Published: October 2019

AbstractThe primary purpose of present study is to “prove” that the angle and distance between the superior mesenteric artery (SMA) and aorta are significantly correlated with the body mass index (BMI). This in turn indicates the strong etiological role of this factor for the causation of SMA syndrome. The superior mesenteric artery syndrome is characterized by the compression of the third segment of the duodenum by the mesentery at superior mesenteric artery level and a resulting duodenal (±gastric) dilatation. The disease is closely related with the depletion of the fat pad between the vessels narrowing the angle and reducing the distance between the vessels. A prospective study of 300 patients (163 males and 137 females) in the age range of 40-70 years (mean age 51 years) who had undergone multislice detector CT scan in Alzahra Hospital for various other complaints in the year 1395. CT scans had been performed with routine protocol comprising of plain phase followed by arterial and venous phases to measure the angle between the aorta and superior mesenteric artery,BMI was also calculated. Mean values for distance and angle were obtained with P value of 5% and 95 % confidence intervals. Pearson coefficients and T test were also calculated and results were tabulated. A strong positive correlation was observed between BMI and the angle between the aorta and SMA. With increment in BMI, the angle also increases leading to a smaller chance of developing superior mesenteric artery syndrome.

Published: October 2019

Introduction: Central venous catheterization has been usually performed during major surgeries in order of central venous pressure assessment and fluid therapy. Variety of techniques has been performed for central venous catheterization previously but the information in this regard about pediatrics is limited. In the current study, the comparison of electrocardiographic technique with landmark one for central venous catheterization performance has been done. Methods: This is a cross-sectional study conducted on 75 patients underwent central venous catheterization for elective cardiovascular thoracic surgery. In the first step, the location of catheterization was estimated based on body surface landmarks. Then catheterization was done using electrocardiography. Then by cardio-surgeon aid, during open cardiac surgery, the catheter tip location was found (gold standard). Finally, chest X-ray was taken and catheter place based on radiological markers was recorded.Results: In the current study, 75 children with age under 18 years and gender distribution of 42.7% females and 57.3% males were assessed. Mean of central venous catheter depth in gold standard method was 7.5±1.35 centimeters. Significant association between central venous catheter placement in gold standard technique and both landmark and electrocardiographic was seen (P-value<0.001; r=0.94 and P-value<0.001; r=0.77). Logistic regression showed a significant association between weight and placement of catheter tip in landmark technique (P-value=0.038) as following formula (Depth of central venous catheter= 5.33+0.07*weight).Conclusion: Our study showed that the use of ECG for CVC considering carina-to-tip as reference was superior to the landmark. In addition, catheter tip correct position was affected by weight but not height based on landmark technique.

Authors: Mansouritehrani Nedasadat 
Published: October 2019

Introduction: Currently, various methods are being used for determining difficult laryngoscopy. The present study aimed to compare the acromioaxillosuprasternal notch index function with the old head and neck anatomic criteria in predicting difficult laryngoscopy with respect to trachea intubation under general anesthesia in children. Materials and Methods: In this cross-sectional study, 379 children under intubation with general anesthesia entered the study. Patients were divided into two groups: easy laryngoscopy (grades 1 and 2) and difficult laryngoscopy (grades 3 and 4) based on Cormack-Lehane score. The thyromental distance systems, height to thyromental distance, Upper-Lip-Bite test, neck circumference, and acromioaxillosuprasternal notch index were studied and compared. Results: Laryngoscopy was difficult in 48 subjects (38 were grade 3 and 10 were grade 4). Interestingly, no significant difference was detected between easy and difficult laryngoscopies based on the thyromental distance, neck circumference, height to thyromental distance, and acromioaxillosuprasternal notch index (P>0.05). height to thyromental distance , acromioaxillosuprasternal notch index , and neck circumference have a sensitivity of 32.2%, 47.9%, 51.1%, respectively, and the specificity was 52.7%, 45.6%, and 48.9%, respectively. Conclusion: Neck circumference and acromioaxillosuprasternal notch index outperform the height to thyromental distance. On the other hand, Modified Mallampati test is better than Upper-Lip-Bite test in determining difficult laryngoscopy in children.

Published: October 2019

Introduction: We present three cases of ruptured sinus of Valsalva aneurysm concomitant with a cardiac lesion in 2 cases of ventricular septal defect and 1 case of bicuspid aortic valve with mild aortic insufficiency. Case presentation: In 2/3 cases, the site of ruptured sinus of Valsalva aneurysm originated from right coronary cusps and one from non-coronary cusps. Both ruptured sinus of Valsalva aneurysm from right coronary cusps communicated to right ventricle, and one that originated from non-coronary cusps ruptured to right atrium. All cases were diagnosed by transthoracic echocardiography and confirmed by transesophageal echocardiography. Two underwent the surgery, while one did not want to continue treatment. Conclusion: ruptured sinus of Valsalva aneurysm is a rare cardiac anomaly. In the Eastern countries, the most common associated anomalies with ruptured sinus of Valsalva aneurysm are ventricular septal defect and aortic regurgitation. Ruptured sinus of Valsalva aneurysm mainly originates from right coronary cusps and is ruptured into right ventricle. Transthoracic echocardiography and transesophageal echocardiography are employed to confirm the diagnosis. In this cohort, the coexistences of ruptured sinus of Valsalva aneurysm with ventricular septal defect and aortic regurgitation (case 1), ventricular septal defect (case 2), aortic regurgitation and bicuspid aortic valve (case 3) are observed.

Partiremos da análise da trajetória de três colecionadores de arte com diferentes perfis. Jacque Van de Beuque, artista plástico francês, nascido em 1922, buscou no Brasil, através do imaginário dos trópicos, esquecer os horrores da guerra e acabou por construir uma coleção que deu origem ao Museu Casa do Pontal; Lina Bo Bardi, arquiteta italiana nascida em 1914, chegou ao Brasil a convite de Assis Chateaubriand para construir do Museu de Arte de São Paulo e acabou por morar alguns anos na Bahia, período em que formou sua coleção de arte popular brasileira e, por fim, Emanoel Araújo, artista plástico baiano, nascido no Recôncavo em 1940, amealhou durante sua vida uma numerosa coleção que deu origem ao Museu Afro Brasil em São Paulo. Pretendemos então, avaliar o papel exercido pelos colecionadores e pelos museus no processo de formação de discursos sobre arte popular a partir da seleção e classificação dos artistas e de suas obras, ao definir quais os objetos que se destacam em suas coleções. Nossa comparação levará em conta como cada um dos três vê as carrancas do Rio São Francisco criadas do Mestre Francisco Biquica Guarany.

Proximal tibial resection is an important surgical step in total knee arthroplasty (TKA). Normally, an anterior surface of tibia used as anatomical landmark (extramedullary method), this method based on visual judgment. (D.C. Marchant, 2005) calculated ratio for center of the ankle, ratio of lateral distance to total inter-malleolar distance was observed at 0.57 in normal ankle sample. However, there is no study documenting about accuracy of ratio for center of the ankle as a landmark for proximal tibial resection in computer assisted TKA (CAS TKA).This was prospective study on 65 patients with osteoarthritis knees scheduled to receive CAS TKA from January to December 2018. Proximal tibial resection was simulated by extramedullary method and ratio for center of the ankle respectively. Tibial resection alignment were recorded by CAS.Tibial resection alignment within 3 degrees was 84.6 and 92.3% for extramedullary method and ratio for center of the ankle method. The average total tibial resection alignment was 0.84 and 0.66 degrees of valgus (p = 0.497), the average tibial resection alignment within 3 degrees from mechanical axis was 0.33 and 0.55 degrees of valgus (p = 0.513) and the average tibial resection alignment more than 3 degrees from mechanical axis was 3.60 and 1.5 degrees of valgus (p = 0.049) for extramedullary method and ratio for center of the ankle method respectively.Ratio for center of the ankle demonstrated result in numeric value and anatomical landmark of lateral and medial malleoli was simple to identified. Our results shown the tibial resection alignment with ratio for center of the ankle method had higher accuracy and lower average degrees of outlier than extramedullary method.

Published: October 2019

PurposeInnovative technologies such as robotic assistance and intraoperative load sensors for total knee arthroplasty (TKA) aim to reduce outliers, as well as to address patient dissatisfaction. There is currently no information available that assesses the findings of using these technologies together during TKA.MethodsIntraoperative data on alignment, gap spacing, and quantitative balance was prospectively collected in a cohort of 79 consecutive TKAs performed with robotic assistance. An instrumented trial component was utilized that captured medial and lateral tibio-femoral loads, allowing the quantitative assessment balance.ResultsOf the 79 knees, 58 (73%) had varus alignment and 21 (37%) had valgus. We divided these groups into correctable and fixed deformities. Correctable varus knees: At trial reduction 30% of the knees demonstrated quantitative imbalance at trial reduction. Fixed varus knees. At trial reduction 55% (of knees were deemed imbalanced. Correctable valgus knees: At trial reduction, 35% were imbalanced. Fixed valgus knees: Half of the knees (n=2) were imbalanced at trial reduction. The imbalance in all groups was addressed with combinations of bone and soft tissue adjustments so that at final implantation 99% of cases (n=78) were quantitatively balancedConclusionWhile the robot was both precise and accurate with its cuts to create appropriate gap spaces, only 57% were quantitatively balanced. Ultimately, almost all knees were balanced with final implants, but that state required the use of additional techniques, including soft tissue and bony modifications. More data is needed to determine if these technologies will equate to increased clinical success.

Implant malalignment during TKA may lead to suboptimal outcomes. Accuracy studies are typically performed with experienced surgeons; however, it is important to study less experienced surgeons when considering teaching hospitals where younger surgeons are operating. Therefore, the purpose of this study was to assess whether computer-assisted TKA (CATKA) allows for more accurate and precise implant position to plan when compared to manual TKA (MTKA) when the surgery is performed by less experienced surgeons.Two surgeons, currently in their fellowship training and having minimal CATKA experience, performed a total six MTKA and six CATKA on paired cadaveric knees. Computed tomography (CT) scans were obtained for each knee pre- and post- operatively. CT scans were analyzed to compare post-operative implant position to the pre-operative planned position. Mean system errors and standard deviations were compared between CATKA and MTKA for the femoral component sagittal, coronal, and axial planes and the tibial component in the sagittal and coronal planes. A 2-Variance testing was performed using an alpha=0.05.CATKA had greater accuracy and precision to plan than MTKA for: femoral axial plane (1.1o±1.1o vs. 1.6o±1.3o), coronal plane (0.9o±0.7o vs. 2.2±1.0o), femoral sagittal plane (1.5o±1.3o vs. 3.1o±2.1o), tibial coronal plane (0.9o±0.5o vs. 1.9o±1.3o) and tibial sagittal plane (1.7o±2.6o vs. 4.7o±4.1o). There was no statistical difference between surgical groups or between the two surgeons performing the cases.With limited CATKA experience, the fellows showed increased accuracy and precision to plan for femoral and tibial implant positions. Furthermore, these results are comparable to what has been reported for an experienced surgeon performing CATKA.

This study reports on mid-term survivorship and outcomes of medial bicompartmental robotic assisted primary knee arthroplasty.Forty-six knees in 43 patients with a mean 6 year follow up were consented to participate in this retrospective data collection. All patients received primary treatment for knee osteoarthritis with fixed metal backed medial femoral and patellar implants. Demographic data along with post-operative outcomes were collected including; the KSS patient portion, implant survivorship, and patient satisfaction.All patients were included in the survivorship analysis. 45 knees in 42 patients were available for analysis of KSS and patient satisfaction. The mean follow-up was 6.1 years (range 2.1 - 7.6 years). Sixty-three percent of patients were male and 37% female. Average age at the time of surgery was 67 years and average BMI was 29. There were 3 revisions and 1 arthroscopic surgery resulting in 97.8% all cause survivorship. 86.7% of patients reported walking more than 10 blocks and 95.6% of patients reported walking without the use of assistive devices for support. All patients were able to go up and down stairs, 48.9% required use of a rail. 82.2% of patients reported being satisfied with their knee at 5 years.In this study we found 97.8% survivorship at a mean 6 year follow up with 82.2% of patients being very satisfied or satisfied with the implant. Longitudinal follow up at 7 and 10 years will continue to evaluate long term outcomes on the variations of robotic assisted knee arthroplasty.
