AIMS: We aimed to quantify the relative contributions of the medial femoral circumflex artery (MFCA) and lateral femoral circumflex artery (LFCA) to the arterial supply of the head and neck of the femur. MATERIALS AND METHODS: We acquired ten cadaveric pelvises. In each of these, one hip was randomly assigned as experimental and the other as a matched control. The MFCA and LFCA were cannulated bilaterally. The hips were designated LFCA-experimental or MFCA-experimental and underwent quantitative MRI using a 2 mm slice thickness before and after injection of MRI-contrast diluted 3:1 with saline (15 ml Gd-DTPA) into either the LFCA or MFCA...

BACKGROUND: Disparate outcomes in critical limb ischemia (CLI) persist between ethnicities. The contribution of modifiable factors versus intrinsic biologic differences remains unclear. Hence, we aimed to quantify the associations between ethnicity and anatomic patterns of arterial occlusive disease in CLI, adjusting for known atherosclerotic risk factors. METHODS: We performed a retrospective, single-center review of consecutive patients presenting to the vascular surgery service with CLI...

PURPOSE: Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by HIV, can lead to the development of pseudoaneurysms. Rupture of pseudoaneurysm is a dramatic event in such patients and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, that consist in ligation, repair or substitution of the damaged arterial segment, employing when possible biological grafts...

Vascular complications of intravesical instillation of bacillus Calmette-Guérin (BCG) are rare. BCG is an attenuated strain of Mycobacterium bovis (M. Bovis) that was initially developed for vaccination against tuberculosis, but it has also been used as an adjuvant treatment for bladder transitional carcinoma. We report a patient with a history of instillation of BCG two years before, who underwent surgical treatment of 2 pseudoaneurysms. The first, located in the left superficial femoral artery (SFA), was resected and the artery was ligated because he had a history of femoropopliteal occlusion...

Femoral artery injuries are a rare complication of blunt trauma in children that require expeditious diagnosis and treatment to prevent permanent limb dysfunction. Point-of-care ultrasonography of femoral vessels is a well-established emergency physician technique for ruling out deep vein thrombosis and guiding femoral vessel catheterization. We present the first report of a pediatric emergency physician diagnosing a traumatic femoral artery thrombus using point-of-care ultrasonography.

Limb remote ischemic postconditioning (LRIP) has been confirmed to reduce the ischemia-reperfusion injury but its mechanisms are still not clear. This study clarified the mechanism of LRIP based on the nicotinamide-adenine dinucleotide phosphate (NADPH) oxidase and Myeloid differentiation factor 88 (MyD88)-Tumor necrosis factor (TNF) receptor-associated factor 6 (TRAF6)-P38 pathway of neutrophils. Rat middle cerebral artery occlusion (MCAO) model was used in this study. Ischemia-reperfusion injury was carried out by MCAO 1...

Background Despite guideline-compliant prophylaxis, an increased rate of deep venous thrombosis (DVT) formation has been reported following autologous versus implant-based breast reconstruction. We hypothesized that tight abdominal fascia closure might decrease lower extremity venous return and promote venous stasis. Methods An observational crossover study of patients who underwent autologous breast reconstruction using transverse rectus abdominis musculocutaneous/deep inferior epigastric artery perforator flaps was conducted...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...
