MeSH terms: Case Reports

Introduction:
Advanced-stage thymic malignancies are a heterogeneous group of mediastinal tumors that include thymoma and thymic carcinoma infiltrating the surrounding thoracic structures. When the tumor infiltrates the superior vena cava (SVC), radical resection can be selectively achieved via en bloc SVC resection and its prosthetic conduit replacement. We herein report a case of SVC replacement for thymic carcinoma en bloc radical resection.
Case presentation:
A 75-year-old Japanese man presented at our hospital due to progressive dyspnea and edema of his face and upper extremities. CT showed a 55 × 40 × 38-mm tumor located at the anterior mediastinum lesion. This tumor had invaded the superior vena cava and both brachiocephalic veins. We performed surgical resection for the thymic carcinoma located at the mediastinum that invaded the superior vena cava and both brachiocephalic veins. The surgery was performed through a full median sternotomy and transmanubrial approach without using an artificial heart and lung. The tumor involved the SVC, right brachiocephalic vein (RBCV) and left brachiocephalic vein (LBCV). We performed SVC replacement for thymic carcinoma en bloc radical resection.
Discussion:
This report has two important implications. First, a venovenous shunt (VVS) from the distal LBCV to the right auricle was very useful and safe before performing an SVC complete clamp. The second implication of our study was that using a PTFE with a large inner diameter may prevent thrombus occlusion.
Conclusions:
We experienced SVC replacement for thymic carcinoma en bloc radical resection. We were able to safely performed this surgery using our usual approach.

MeSH terms: Case Reports

Scleredema diabeticorum is a rare cutaneous manifestation of diabetes mellitus. We present a case of an obese male with poorly controlled diabetes who came to the hospital with upper back pain and subsequently developed sepsis due to a small deep-seated abscess in his back that was drained and treated with antibiotics. He was also found to have extensive induration of the skin over his back and neck. Skin biopsy confirmed the diagnosis of scleredema diabeticorum.
Interdisciplinary Surgical Treatments and Long-Term Outcomes of Lumbar Spinal Tumors With Retroperitoneal Involvements: A Retrospective Case Series Study
Authors: Shaohui He, Yifeng Bi, Chen Ye, Dongyu Peng, Jianru Xiao, Haifeng Wei
Journal: Front Oncol (2021)
Keywords: case series, en bloc, interdisciplinary surgery, lumbar spinal tumor, prognosis, vascular and urinary involvements

Purpose:
Surgical treatments are technically challenging for lumbar spinal tumor (LST) with extensive retroperitoneal involvements. Our study aimed to report the experience and outcomes concerning interdisciplinary surgical collaborations in managing such LSTs.
Patients and methods:
Nine patients underwent interdisciplinary surgical treatments which were performed by specialists, namely, spinal, vascular, and urinary surgeries. Data on clinical characteristics were collected, and the Visual Analogue Scale (VAS) and the Japanese Orthopaedic Association Score (JOAS) were used in the evaluation before and after surgery. The postoperative complications and the long-term outcomes were reported as well.
Results:
The interdisciplinary work included double J catheter indwelling (n = 9), nephrostomy (n = 5), replacement of the common iliac vein (n = 2), abdominal aorta repair (n = 3), and vital vessel repair (n = 8). The early-stage complications included complaints of moderate low back pain and slight implant shift (n = 1, 11.1%) and tardive ureterodialysis (n = 1, 11.1%). The 3- and 5-year disease-free survival rates were 76.2 ± 14.8 and 50.8 ± 23.0%, respectively, during the mean follow-up of 34.6 ± 17.9 months (range, 9.5-68.7). Besides this, more blood loss was associated with recurrent and metastatic tumor status (p = 0.043) and surgery time >5 h (p = 0.023). Remarkable pain relief and favorable quality of life were achieved based on the postoperative VAS (3.3 ± 0.9, p < 0.001) and JOAS (16.6 ± 0.5, p < 0.001).
Conclusions:
The treatments of LSTs with wide-range retroperitoneal involvements require interdisciplinary surgical collaborations to lower the risks and improve the long-term outcomes. High-quality prospective cohort studies with large samples are warranted to establish general surgical protocols in managing LSTs with extensive retroperitoneal involvements.
Early Left Ventricular Thrombus Formation in a COVID-19 Patient with ST-Elevation Myocardial Infarction
Authors: Harish Sharma, Sudhakar George
Journal: Case Rep Cardiol (2020)
MeSH terms: Case Reports

Background:
Left ventricular thrombus (LVT) is a complication of acute myocardial infarction (AMI) due to localised haemostasis. LVT is typically seen 3-12 days following AMI and is seldom seen within the first 24 hours. LVT increases the risk of mortality due to systemic thromboembolism. Patients with Coronavirus Disease-19 (COVID-19) are potentially hypercoagulable and this may promote early development of LVT.
Case:
A 50-year-old man with no past medical history was admitted with a severe diabetic ketoacidosis following a 4-day history of cough and fever. The patient tested positive for COVID-19 and required intensive care treatment for ventilation and haemofiltration. After returning to ward-based care, the patient developed chest pain and electrocadiographic changes consistent with an acute anterior ST-elevation myocardial infarction. Emergency percutaneous coronary intervention was performed to the left anterior descending artery. However, the patient developed diuretic-resistant pulmonary oedema and a bedside echocardiogram revealed significant LVT despite only 4 hours of chest pain. The thrombus was associated with the anteroseptal wall of the left ventricle which was hypokinetic but not aneurysmal. An intra-aortic balloon pump (IABP) was inserted, but the patient developed ipsilateral lower limb ischaemia due to the formation of thrombus in the femoral artery and irreversible cardiogenic shock from which he ultimately succumbed.
Conclusion:
COVID-19-positive patients are potentially hypercoagulable, and MI in this population may precipitate LVT earlier than expected. Consideration should be made for routine early screening of post-MI COVID-19 patients for LVT. If detected, anticoagulation may reduce the risk of cardiovascular mortality in this high-risk group.
Minimally Invasive Endoscopic Approach to the Cervicothoracic Junction for Vertebral Osteomyelitis

MeSH terms: Case Reports

The selection of an anterior, lateral, or posterior approach to the cervicothoracic junction for surgical treatment of vertebral osteomyelitis is still a matter of debate. These ordinary approaches generally require an extensile exposure. This article describes a less invasive approach case of a vertebral osteomyelitis of T2/3 using a video-assisted operating technique of thoracic surgery (VATS). A 78-year-old female underwent anterior debridement and interbody fusion with bone graft at T2/3 using a lateral surgical approach through a right thoracotomy with VATS. The VATS through two small skin incisions in the axillary region provides a good view without requiring elevation of the scapula with extensile muscle dissection and rib resection. There was no complication without partial lobectomy due to pleural adhesion during the perioperative period. Currently, at 1 year after operation, the patient has no back pain with neurologically normal findings and no inflammation findings (CRP was 0.01 mg/dl). Although the operating field of the upper thoracic level in the lateral approach is generally deep and narrow, the VATS provides a good view and allows us to perform adequate debridement and bone fusion at the T2/3 level with a less invasive approach than those previously described anterior or laterally or posterior approach.
