Mycotic aneurysm and renal transplantation.

A case of mycotic aneurysm secondary to suppuration of a renal transplant is reported. This aneurysm was responsible for ischemia of the leg and was treated successfully by ligation and venous bypass grafting.

[Hereditary protein S deficiency and recurrent venous thrombosis. Study of a family].

Hereditary protein S deficiency was detected in three subjects belonging to three generations of one single family. The deficiency was heterozygous and was associated with recurrent venous thromboembolism in two of the subjects affected. Plasma analysis by two-dimensional immunoelectrophoresis showed that the protein S fraction bound to C4b-binding protein was quantitatively normal, whereas the free protein S fraction was much reduced.

[Revascularization of the 2 lower limbs from the descending thoracic aorta without laparotomy].

Arterial bypass of the lower limbs from the thoracic aorta approached through a thoracic or abdominal route has already been described. The technique reported here is original in that the descending thoracic aorta is exposed through thoracotomy, and the prosthesis is passed behind the left kidney, then, for the right leg bifurcation, through Retzius' space without laparotomy. Two patients were operated upon with this technique which is described in detail, together with its potential indications, advantages and disadvantages.

[Aneurysm of the trunk of the superior mesenteric artery and polyaneurysmal disease of the right paracolic arcade of fibromuscular hyperplasia type. A case].

The authors report a case of an aneurysm of the mid part of the superior mesenteric artery associated with polyaneurysmal disease of the right paracolic arterial arcade. Features of special interest in this case were the rarity of the location of the aneurysm and its aetiology: a hyperplastic fibromuscular angiodysplasia.
