"Marsupial cava" and ruptured abdominal aortic aneurysm. A case report and review of the literature.

A patient with a ruptured abdominal aortic aneurysm underwent an emergency operation. A rare anomaly of inferior vena cava, known as "marsupial cava," was found. The iliac vein confluence crossed anteriorly (rather then posteriorly) the right common iliac artery.

[Incidence and treatment of vascular prosthesis infection in the groin. Personal experience].

The incidence of prosthesis infection in the groin ranges between 1 and 3%, with high morbidity and mortality rates. Contamination, irrespective of whether it is endogenous or exogenous, may occur during surgery of afterwards due to a secondary bacterial load which is often associated with a traumatic surgical technique for tissues, often in emergency surgery or re-operations.

[Controversies regarding an algorithm and the type of surgical treatment in popliteal aneurysms].

Having outlined their 20-year experience in the treatment of popliteal aneurysms (PA), the authors discuss the type of therapeutic approach used. From the authors' point of view an overly aggressive approach to PA is unnecessary, and the decision to adopt a given therapy must instead be weighed up on the basis of the careful clinical evaluation of each individual case, taking into account the patient's clinical conditions at the time, the pathological anatomy of the lesion and its consequences. The authors divide primary PA into symptomatic and asymptomatic cases; in the latter surgery is definitely indicated and the possible contraindications represented by anesthesiological risk or small aneurysm diameter need not be evaluated.
