Unibody design for aortic disease with a narrow aortic bifurcation: tips and tricks for success.

Background: Surgical management of patients with abdominal aortic diseases associated with distal narrowing is a challenging situation.

Objectives: To evaluate outcomes of unibody bifurcated endovascular stent graft repair.

Methods: This is a retrospective, observational, multi-institutional database study of a cohort of consecutive cases, approved by the local Ethics Committee.

Cyclooxygenase-2 expression is associated with infiltration of inflammatory cells in oral and skin canine melanomas.

Melanoma is a fast-growing tumour in dogs and represents 7% of the total malignant neoplasms from the skin and is the most common tumour found in the oral cavity. In these tumours, high expression of cyclooxygenase-2 (COX-2) is associated with a poor prognosis. The aim of this study was to verify if the overexpression of COX-2 is related to the modulation of lymphocytes and if it is associated with the angiogenic and proliferative capacity of the melanoma.

Inferior gluteal artery pseudoaneurysm after fall from a bicycle: case report.

Pseudoaneurysms of gluteal arteries are rare, especially involving the inferior gluteal artery. They are mainly associated with penetrating trauma, infections, or pelvic fractures. A minority of cases are caused by blunt traumas, with only six cases reported in English.

Nutcracker syndrome and deep venous thrombosis in a patient with duplicated inferior vena cava.

Duplicated inferior vena cava is a rare anomaly, and thrombosis in one or both segments is even less frequent. We present a case of deep venous thrombosis of the left lower limb involving the popliteal, femoral, and iliac veins as well as the left segment of the duplicated vena cava and nutcracker syndrome. After catheter-directed thrombolysis complemented by mechanical thrombolysis, the compromised veins had complete revascularization; the nutcracker syndrome was treated with stent placement, followed by the use of anticoagulants.
