We report two cases of pulmonary arterial hypertension (PAHT) in HIV infected patients who never were, or had ceased to be, drug addicts. A study of these cases and a review of the literature show that this association is not fortuitous and persists after the classical causes of PAHT (pulmonary embolism, toxic factors, cirrhosis) have been excluded. The clinical features and the results of complementary cardiovascular examinations are identical with those of the so-called "primary" PAHT. ⋯ Histology displays signs of plexogenic pulmonary arteriopathy, as in primary PAHT. In HIV patients pulmonary arterial hypertension occurs independently of the degree of immunodeficiency. Its relation with other HIV-related vasculites and their physiopathology are discussed.

The results of the revascularizations carried out over a 10-year period for "critical" chronic ischaemia, using the femoropopliteal bypass technique, have been retrospectively analyzed. In all, 600 patients underwent femoro-distal revascularization in 644 limbs, and 695 bypasses were performed. The hospital mortality rate was 4.3 percent. ⋯ The failure of revascularization ending in amputation did not significantly increase the postoperative mortality rate (4.1 percent versus 4.6 percent), but the life expectancy of patients who were amputated was significantly lower than that of patients who were not (55 +/- 5 percent versus 63 +/- 3 percent at 3 years; P = 0.03). The factors predictive of successful bypass were examined; they included age, clinical stage, diabetes, bypass material, site of distal implantation, revascularization procedure and reoperation. Femoro-distal revascularization makes it possible to cope with the challenge of limb salvage, even when the receiving vessel is an artery of the foot.
