Authors: Turunen P. , Wikström H. , Carpelan-Holmström M. , Kairaluoma P. , Kruuna O. , Scheinin T. 
Published: January 2017

Backround and Aims: The aim of this study was to establish whether smoking is associated with complicated diverticular disease and adverse outcomes of operative treatment of diverticular disease. Smoking has been associated with increased rate of perforations in acute appendicitis as well as failure of colonic anastomosis in patients resected for colonic tumours. It has also been suggested that smoking is a risk factor for complicated diverticular disease of the colon. Material and Methods: Retrospective investigation of records of 261 patients electively operated for diverticular disease in Helsinki university Central Hospital during a period of five years. Results: The smokers underwent sigmoidectomy at a younger age than the non-smokers (p = 0.001) and they had an increased rate of perforations (p = 0.040) and postoperative recurrent diverticulitis episodes (p = 0.019). Conclusions: We conclude that smoking increases the likelihood of complications in diverticulosis coli. The development of complicated disease also seems to proceed more rapidly in smokers.
Comparison of Linear versus Circular Stapling Techniques in Laparoscopic Gastric Bypass Surgery — A Pilot Study
Authors: Giordano S. , Tolonen P. , Victorzon M. 
Published: January 2017

Background: There is major variability in how the gastrojejunostomy (GJ) is created when laparoscopic gastric bypass (LRYGB) is performed. This is a prospective, non-randomised pilot comparison of two different techniques during our learning curve period performed by two different surgeons with similar surgical experience. Methods: From March 2006 until May 2008, 71 consecutive patients, 28 men and 43 woman, mean age 44 (range 24 to 62 years) who were operated for morbid obesity by laparoscopic bypass surgery have been included. Mean preoperative Body Mass Index (BMI) (range) was 47 (34–63). The patients were divided into two groups on the basis of the stapler used. Group 1 comprised 30 patients who underwent surgery using a 25 mm circular stapler to create the GJ. Group 2 comprised 41 patients who underwent surgery using a 45 mm, blue cartridge linear stapler. Operative time, intra-operative complications, hospital stay, major and minor complications were detected. Results: Intra-operative complications occurred in 4 patients (13.3%) in Group 1, in 5 patients (12.2%) in Group 2. Re-operations occurred 3 times (10.0%) in Group 1, and 4 times (9.8%) in Group 2 due to anastomotic complications, bleeding and/or bowel obstruction. Major complications occurred in four patients in Group 1 (13.3%) and in seven patients in Group 2 (17.1%). There was a significant difference in the overall morbidity rate (major and minor complications), which was 56.7% in Group 1 and 34.1% in Group 2 (p = 0.05). Mean operative time in Group 1 was 135 minutes, and in Group 2 122 minutes. Mean hospital stay was significantly shorter in Group 2 (3.9 days) than in Group 1 (5.7 days, p = 0.04). Conclusions: Learning to handle the technique when performing the gastrojejunostomy during laparoscopic gastric bypass surgery may be faster and easier by using the linear stapler. This may be important knowledge for centres considering starting LRYGB practice, although the surgeon factor needs to be taken in account. The results should be interpreted with caution because the confounding effect of one surgeon performing one type of operation while the other surgeon (is performing) the second type of operation could not be taken into account in this prospective non-randomized analysis.

Authors: Turtiainen J. , Saimanen E. , Partio T. , Kärkkäinen J. , Kiviniemi V. , Mäkinen K. , Hakala T. 
Published: January 2017

Background and Aims: This multicenter prospective observational study defined the incidence and risk factors of surgical wound infections (SWI) after infrarenal aortic and lower limb vascular surgery procedures and evaluated the severity and costs of these infections. Methods: The study cohort comprised of 184 consecutive patients. Postoperative complications were recorded. The additional costs attributable to SWI were calculated. Results: Eighty-four (46%) patients had critical ischaemia, 81 (45%) patients underwent infrainguinal bypass surgery and 64 (35%) received vascular prosthesis or prosthetic patch. Forty-nine (27%) patients developed SWI. Staphylococcus aureus was the leading pathogen cultured from the wound. Forty-seven of the 49 infected wounds responded to and healed with the treatment. SWI was the cause of one major amputation. Independent predictors for SWI were infrainguinal surgery (OR 7.2, 95% Cl 2.92–17.65, p < 0.001), obesity (OR 6.1, 95% Cl 2.44–15.16, p < 0.001) and arteriography injection site within the operative area (OR 2.5, 95% Cl 1.13–5.48, p = 0.02). The average cost attributable to SWI was 3320 €. Conclusion: The incidence of SWI after vascular surgery is high. The risk factors for SWI are infrainguinal surgery, obesity and arteriography injection site within the operative area. SWI increases morbidity and costs of operative treatment.
African American Consent and Nonconsent Cases: Are There Significant Differences?
Authors: Dodd-McCue Diane , Tartaglia Alexander 
Published: January 2017

Background Previous research has examined the differences in organ donation consent rates between African Americans and other racial/ethnic groups. However, there is limited examination of whether differences exist between African American families that consent and those that do not. Objective To examine if there are significant differences between African American families that consent to donation compared to those that do not. Methods A random sample of 120 African American potential donor cases from an academic medical center between 1997 and 2004 were included in this study. Variables of interest included next-of-kin relationships, family interactions, knowledge of donor wishes, family initiation of the donation discussion, and satisfaction with the donation process. Results The data include 32 consent and 88 nonconsent cases. Compared to nonconsent cases, consent cases differed significantly in next-of-kin knowledge of donor wishes, frequent involvement of parents, and infrequent involvement of spouses. Donor wishes were known in 19% of consent cases but in none of the nonconsent cases. A parent was the dominant next-of-kin decision maker in 68% of consent cases, compared to 36% of nonconsent cases. A spouse assumed the dominant role in 29% of nonconsent cases but in only 6% of consent cases. Of these differences, wishes known, parental involvement, and spousal involvement were statistically significant ( P= .000, P= .002, and P= .013, respectively). Conclusions The results highlight the statistically significant differences between African American consent and nonconsent cases: knowledge of donor wishes and those involved in the donation decision. These results reinforce the importance of programs that encourage African American families to discuss donation with loved ones.
5-Year Angiographic and Clinical Follow-up of Coil-Embolised Intradural Saccular Aneurysms

Published: January 2017

The purpose of the paper is the follow-up of embolised intradural saccular Arterial Aneurysms (AA), excluding giant, dissecting, inflammatory, fusiform or AA associated to BVAM. Since its introduction in 1991, the Guglielmi Detachable Coil has offered protection against aneurysmal rebleeding in the critical few days and months after SAH regardless of the grade. A number of questions remain: is complete angiographic obliteration necessary at first embolisation? What duration of clinical / angiographic follow-up (FU) is required to ensure the risk of haemorrhage has been eliminated? What is the long-term protection against rebleeding? One hundred and two patients with 160 intradural saccular AA embolised before april 1997 were selected for this study. They had at least 5-yrs clinical FU, of which 22 patients had a mid-term (3 years) and 45 patients had a 5-year or more angiographic FU (mean 67,7 months per patient). Twenty-eight embolised AAs with 100% occlusion at 1 year, remained unchanged on the 5-year angiograms. A further 14 patients with complete occlusion at 1 year showed persisting complete occlusion on angiogram at 3-years FU, which in our series means that complete occlusion after the first year post-embolisation implies that the aneurysm will remain completely occluded. All secondary spontaneous thromboses (27.6% of cases), occurred during the first year pos-embolisation. In six patients with subtotal or partial occlusion no change was seen for three consecutive years of FU; none showed later change at 5-year angiography. Below 80% occlusion our series does not provide enough information but we consider the situation instable. No mortality related to the procedure was observed in the unruptured AA group. No bleeding or re-bleeding has occurred since the beginning of our experience (1993) in saccular AA treated by GDC-Coil. Coil-embolisation of properly selected patients is effective in protecting against bleeding or re-bleeding at short and long-term with stable morphological results provided a strict follow-up control is established at short term.

The authors reviewed 531 patients with cerebral aneurysms treated with Guglielmi detachable coils (GDCs) over 5 years to clarify both the advantages and disadvantages of embolization based on the evidence of complications by aneurysm profile. There were 52 technical complications, 25 of which resulted in unfavorable patient outcomes. Intraoperative rupture, the most serious complication exacerbating the patient's condition, occurred in 19 patients, 4 of whom expired. All of these aneurysms were very small and were mostly located in the AcomA and PICA portions. Thirteen patients encountered thromboembolic complications, 6 of whom were elderly with acute ruptured aneurysms at MCA and the tip of BA. For large or giant aneurysms manifesting the mass effect, particularly those in the ICA-C2 portion compressing the optic nerve, the saccular packing did little to ameliorate the symptoms, and subsequent surgical or endovascular trapping was needed. Therefore, saccular embolization of endovascularly difficult, very small AcomA aneurysms and large C2 aneurysm with visual symptoms should be used sparingly based on a risk-benefit assessment.

Published: January 2017

The purpose of this study was to evaluate the efficacy and safety of staged carotid stenting (CS) and carotid endarterectomy (CEA) for bilateral internal carotid artery stenosis. With this strategy, initial carotid stenting was performed for the high grade carotid stenosis to reduce the risk of subsequent CEA. Eight patients were treated with staged CS and CEA; CS for asymptomatic side followed by CEA for symptomatic side. Sufficient revascularization was obtained in all procedures but one CS procedure. Two minor stroke caused by distal embolism occurred during the perioperative period of CS. Postprocedural persistent hypotension was observed in one CS procedure. The mean interval between CS and CEA was 19.8 days. In conclusion, although our strategy has some advantages such as avoidance of bilateral cranial nerve palsy and shorter admission period over staged CEA, relatively high complication rate was noted at the first CS without any stroke morbidity post CEA. Our preliminary result showed that further reduction of periprocedural complication rate at the initial stenting is mandatory for this approach justified.
Anatomic Variations of the Superficial Middle Cerebral Vein: Embryologic Aspects of the Regressed Embryonic Tentorial Sinus
Authors: Chung J. I. , Weon Y. C. 
Published: January 2017

The embryonic tentorial sinus usually regressses during postnatal development, but its typical prenatal drainage patterns and intradural anastomoses can be depicted as various developmental phenotypic representations. Here, we tried to clarify the variant types of the superficial middle cerebral vein (SMCV) associated with the embryonic tentorial sinus. Total 41 patients and 82 hemispheres were included in this study. CT angiography was performed in all patients as screening for cerebrovascular disease or other intracranial disorders. A separate workstation and 3D software were used to evaluate the cranial venous systems with 3D volume rendering techniques, thin-slice MIP images, and MPR techniques for the analysis of its complicated angioarchitecture. Variations of the SMCV were classified according to the developmental alterations of the embryonic tentorial sinus, including sphenoparietal sinus (cranial remnant of tentorial sinus), basal sinus (floor of middle cranial fossa), petrosal and caudal remnant of the tentorial sinus. Secondary intradural anastomoses of cavernous and superior petrosal sinuses were also evaluated for the efferent pathways. The most frequent type of remnant tentorial sinus, sphenoparietal sinus was present in 49% (40/82) of hemispheres examined. Other regressed patterns of embryonic tentorial sinus were also identified in 38% (31/82): nine caudal remnant type around the transverse sinus, 12 petrosal type, one basal type, five unclassified cases, and mixed type were found in four cases. Secondary intradural cavernous sinus anastomosis was seen in 44% (36/82), however the most prevalent pattern was no anastomosis (46/82) with cavernous sinus. Only one case of superior petrosal sinus anastomosis was found in this series associated with basal sinus type. Anatomic variations of SMCV can be clearly demonstrated with embryologic aspects of the tentorial sinus according to its developmental regression and postnatal secondary adaptations of cerebral venous drainage.
Anatomic Variations of the Deep Cerebral Veins, Tributaries of Basal Vein of Rosenthal: Embryologic Aspects of the Regressed Embryonic Tentorial Sinus
Authors: Chung J. I. , Weon Y. C. 
Published: January 2017

The embryonic tentorial sinus regresses at the 60–80 mm embryologic stage and most of the deep venous channels constitute the basal vein of Rosenthal (BVR). Persisting remnants of the embryonic tentorial sinus can be seen in the adult configuration of the BVR. We tried to explain the anatomic representations of the BVR associated with the remnant embryonic tentorial sinus. A total 41 patients and 82 hemispheres were included in this study. CT angiography was performed in all patients as screening for cerebrovascular disease or other intracranial disorders. A separate workstation and 3D software were used to evaluate the cranial deep venous systems with 3D volume rendering techniques, thin-slice MIP images, and MPR techniques for the analysis of complicated angioarchitecture. Variations of the BVR were classified according to the developmental alterations of efferent pathways into four groups: telencephalic group (A) including tributaries of the uncal vein, inferior frontal vein, anterior communicating vein, and inferior striatal vein; diencephalic group (B) of the interior ventricular vein and peduncular vein; tegmental bridging group (C) of the longitudinal LMV anastomosis; tectal group (D) of the superior vermian vein and internal occipital vein in relation to the Galenic connection. The BVR constituted from the embryonic tentorial sinus was also assessed and the developmental aspects reviewed. Remnant embryonic tentorial sinus was visualized in 12% (10/82) of hemispheres, all of them invariably connected with the telencephalic (A) and diencephalic (B) groups. Most of those connections (9/10) to basal venous tributaries originated from the medial tentorial sinus except one case from the lateral tentorial sinus. No Galenic connections of the BVR were identified in 10% (8/82). Various tributaries of the BVR were classified as: Telencephalic group (A) 43% (35/82), Diencephalic group (B) 35% (29/82), Bridging group (C) 11% (9/82), and Tectal group (D) 6% (5/82). Four cases (5%) were unclassified and revealed only small basal tributaries of the BVR without connection to the great vein of Galen. Anatomic variations of the BVR connected with persistent embryonic tentorial sinus could often be demonstrated in adult configurations considering the embryologic aspects of developmental regression and secondary cerebral venous adaptations.
Coil Migration under Stent-Assisted Embolization
Authors: Cho C.S. 
Published: January 2017

Detachable coils are established as a safe and effective treatment option for some patients with intracranial aneurysms. However this treatment is not useful for the treatment of certain types of complicated aneurysms. Wide-necked or broad-based aneurysms are still complicated to embolize because of the risk of coil migration or coil protrusion into the parent vessel. The Neuroform stent has recently been introduced for the treatment of complex aneurysms. The stent functions primarily to provide durable parent vessel protection during embolization. This report demonstrates coil migration occurring as a delayed complication of Neuroform stent-assisedt coil embolization of a small intracranial aneurysm.

Published: January 2017

We report on the safety and efficacy of transarterial and transvenous Onyx embolization in the treatment of dural arteriovenous fistulae (DAVFs) of the cavernous sinus. We reviewed the findings from a retrospectively database for 22 patients with cavernous sinus DAVFs who were treated with either transarterial Onyx embolization alone (n = 8) or transarterial and transvenous Onyx embolization (n = 14) over a four year period. The mean follow-up period after endovascular treatment was 21.6 months (range 3–42 mths). Total number of embolizations was 27 for 22 patients. Two patients were treated transvenously after transarterial embolization. All 22 patients (100%) experienced improvement of their clinical symptoms. All 22 patients (100%) experienced total obliteration of their DAVFs, as documented by angiography performed at a mean follow-up of 5.8 months after the last treatment. No patient experienced a recurrence of symptoms after angiography showed DAVF obliteration. One patient exhibited temporary deterioration of ocular symptoms secondary to venous hypertension after near total obliteration; one had transient V cranial nerve deficit related to transarterial embolization, and two patients exhibited transient III and VI cranial nerve weakness related to transvenous embolization. Two patients experienced recurrent symptoms after incomplete transarterial embolization and underwent transvenous embolization at three and four months. Both patients achieved clinical and angiographic cures. Transarterial and transvenous embolization with Onyx, whenever possible, proved to be a safe and effective management for patients with cavernous sinus DAVFs.
Brachiocephalic Vein Stenosis in Association with Ipsilateral Hyperdynamic Brachio-Basilic Fistula Causing Ipsilateral Facial Swelling and Contralateral Papillodema and Visual Loss

Authors: Kombos T. , Meisel H.-J. , Janz C. , Brock M. 
Published: January 2017

A 44-year-old patient developed paraplegia following rupture of an anterior communicating artery aneurysm. There was no evidence of any spinal lesion. Cerebral angiography showed a paired bihemispheric disposition of the A2 segment. We report this case and consider the anatomical variants of the A2 segment described in literature. The paired bihemispheric variant was reported in 21% of the cases. An azygos (unpaired) artery was observed in 5% and a triplicated A2 segment in 20% of the cases.

Published: January 2017

We report our initial experience of stenting for symptomatic stenoses of the proximal vertebral artery. A total of 25 lesions affecting the proximal vertebral artery were treated by PTA with stent in 23 patients. The lesions involved the vertebral artery ostium in 20 lesions and the nonostial V1 portion in five lesions. The mean stenosis rate of those lesions was 81% pre-stenting and was reduced to 4% post-stenting. There were two transient neurological complications: hemiparesis in one patient and visual acuity disturbance in another. Angiographic follow-up studies more than three months after treatment demonstrated restenosis in three patients. One of these patients was symptomatic. These restenoses were successfully treated by PTA. Our initial results demonstrated that stenting is a feasible and safe method of treating stenosis of the proximal vertebral artery.
Division Tenorrhaphy: A Novel Technique for Chronic or Failed Nonoperatively Treated Achilles Tendon Rupture
Authors: Doty Jesse , Katsuura Yoshihiro , Richardson Nicholas 
Published: January 2017

Here we describe a modified open technique for the repair of a ruptured Achilles tendon using multiple looped sutures with the creation of interdigitating tendon stumps maximizing surface area for suture application as well as allowing for significant tissue overlay. This technique produces a high strength repair that is useful in cases of extensive degeneration or poor-quality tissue. Degenerative tissue may be encountered with chronic ruptures or failed nonoperative treatment, as well as those ruptures that occur at the proximal myotendinous junction. We present 2 cases in which the technique was utilized: one of a failed nonoperatively treated rupture and another of a chronic rupture. The technique was found to be successful for both patients with improvement in visual analogue scale, Achilles tendon total rupture score, American Orthopaedic Foot and Ankle Score, and Foot and Ankle Disability Index. Levels of Evidence: Level IV
