Leiomyosarcoma of the Great Saphenous Vein: Case Report and Literature Review.

Vascular leiomyosarcomas are extremely rare, and involve veins 5 times more often than arteries. In the lower extremity, the great saphenous vein is the most frequent site of origin. We report the case of a healthy 45-year-old patient who presented with a painless mass located proximally in the right thigh in line with the great saphenous vein.

Follow-up of aortic stent grafts: comparison of the volumetric analysis of the aneurysm sac by ultrasound and CT.

Background: The long-term follow-up of patients with endovascular aneurysm repair (EVAR) and a normal surgical risk was defined by the French National Authority for Health (Haute Autorité de Santé) in 2009. The monitoring of the volume of the aneurysm sac theoretically avoids the bias related to the measurement of its diameter alone. The objective of this study was to evaluate how reliable and reproducible the volumetric measurement of the aneurysm sac by ultrasound was compared with computerized tomography angiography (CTA).

Chronic renoprotective effect of pulsatile perfusion machine RM3 and IGL-1 solution in a preclinical kidney transplantation model.

Background: Machine perfusion (MP) of kidney graft provides benefits against preservation injury, however decreased graft quality requires optimization of the method. We examined the chronic benefits of MP on kidney grafts and the potential improvements provided by IGL-1 solution.

Method: We used an established autotransplantation pig kidney model to study the effects of MP against the deleterious effects of warm ischemia (WI: 60 minutes) followed by 22 hours of cold ischemia in MP or static cold storage (CS) followed by autotransplantation.
