[Superior vena cava thrombosis or stricture secondary to implanted central venous access: Six cases of endovascular and direct surgical treatment in cancer patients].

Superior vena cava (SVC) stenosis or thrombosis is a well-known complication of central venous catheterization for endocavitary treatments, hemodialysis, or chemotherapy. In cancer patients, these SVC lesions are often symptomatic due to intimal damage and chemotherapy toxicity. We report our experience with six patients treated between 2007 and 2012 via an endovascular approach (n=5) or a direct surgical approach (n=1).

[Treatment of radiation-induced iliofemoral arterial complications with groin radionecrosis].

Long-term iliofemoral complications induced by radiation include vascular (arterial and venous) lesions, nervous lesions and soft tissue loss that can be cutaneous and subcutaneous and potentially lead to radionecrosis with vessel exposure. We present five cases of groin radionecrosis. There were three men and two women (age 30-73 years).

[Critical ischemia in patients over 80: waiting or evidence-based surgical treatment?].

Critical ischemia is defined by continuous pain, impending sleep, with ankle pressure less than 50mm Hg, and/or first toe pressure less than 30 mm Hg (Dormandy et Rutherford, 2000; Norgren et al., 2007). Treatment of patients aged over 80 requires specific knowledge of arteriopathy at this age and an evaluation of co-morbidity factors (diabetes mellitus, renal failure, ischemic cardiopathy).

[How can we improve the prognosis of infrapopliteal bypasses?].

Infrapopliteal bypasses are often used for critical ischemia, in patients older than 80, in diabetics patients in 20% of cases, and patients with end-stage renal disease in 10% of cases. The goal of this paper is to analyze the systemic factors, which contribute to the clinical results, the technical aspects, which improve the patency of the bypass, and the role of postoperative follow-up. Postoperative mortality in those patients ranges from 3 to 10%, depending on several factors: age, global cardiovascular diffusion, diabetes mellitus, end-stage renal disease.

[What are the guidelines for using a venous segment for an arterial bypass? General review].

Since the first femoropopliteal bypass, performed by J. Kunlin, in 1950, the saphenous vein has remained the material of choice for arterial bypass in a wide variety of localizations. Harvesting must be adapted to vein quality and the length necessary for the bypass.
