[Percutaneous angioplasty of the infra-renal aorta. Report of 9 cases].

Between June 1996 and September 2000, nine angioplasties of the infra-renal aorta were performed in two Surgical Vascular Centers (Hospital Saint-Joseph, Paris, Polyclinic La Baule), in 6 men and three women age ranged from 36 to 72 years (middle age 48 years and 2 months). Eight of these patients presented important stenoses of the middle infra-renal aorta, or in the aortic bifurcation, one of them presented an occlusion, leading to severe intermittent claudication, and rest pain. After endoluminal kissing balloon angioplasty, five aortic stents (five patients), and six iliac primitive arteries stents (in three patients), extended beyond the aorta, were placed.

[Isolated stenosis of the popliteal artery after treatment with methysergide. An anatomopathologic study].

One case of isolate stenosis of the popliteal artery in a young woman is reported in this article. Since acid Methysergide maleate had been taken over a longer period, this lesion was placed into the nosological context of toxic arterial fibrodysplasia. Although such lesions usually recede at the end of treatment, the severity and abruptness of ischemia in this case led to operating the patient.

[Malignant melanoma among the ethnic Melanesian population of New Caledonia].

Melanesian population amounts to 61,270 out of 145,368 inhabitants in New Caledonia according to the last census. Melanesians of phototype VI have no predisposition in regard to malignant melanoma. From 1977 to 1987, 7 cases have been reported.

[Traumatic lesions of the supra-hepaticocaval veins or lessons from failure. Apropos of 5 cases].

Strategic therapeutic principles in 5 cases of injury to supra-hepaticocaval veins were based on vascular exclusion of liver prior to any approach to the lesion. An approach to the intrapericardial inferior vena cava by sternotomy is proposed together with the use of an endocaval shunt introduced through the atrium.

[Indications and tactical aspects of emergency colonic surgery in a tropical environment].

As 92 emergency operations of the colon have been carried out, a record is given of their indications, the most prevailing being, in Africa, intussusceptions and volvulus of the pelvic colon. Out of 64 exercises and colic derivations, 42 ideal colectomies are used as a ground for the analysis of the requirements and limits of this emergency operation. As out of the 7 fistulas they have observed, 6 of them have been outcomes of exeresis of necrosed colic segments, the authors in accordance with the newest bibliographic data, emphasize the importance of mastering the anastomosis technique.
