Late results of reconstructive surgery for renovascular hypertension.

In order to evaluate the late results of reconstructive surgery for renovascular hypertension, a review was made on a series of 120 consecutive patients who underwent operations over a 11 year period. There were 82 males (68.3%) and 38 females (31.7%) with a mean age of 48.4 years. Renal artery by-pass grafts were used in 90% (120/133), a thromboendarterectomy in 5.2% (7/133), and other surgical procedures were performed in 4.8% (6/133). Associated vascular procedures were performed in 38.3% (46/120) of patients. Operative mortality was 2.5% (3/120) overall; there was no mortality in the isolated renal artery reconstructions. There was a clinical success (after a mean follow-up of 48 months) in 80.4% of patients. The most important factors influencing clinical result after renal revascularization were: a generalized atherosclerosis (p less than 0.05), duration of hypertension (p less than 0.01) and the early post-operative response of the blood pressure (p less than 0.01). The overall five- and ten-year actuarial survival probabilities were 85 and 68%, respectively. The most common causes of death were myocardial infarction, stroke and cancer. Cox regression analysis for variables influencing survival indicated that persistence of severe hypertension was the major determinant of late survival (p less than 0.05). Hypertension in females is better tolerated, while younger patients appear to have better results and late survival after surgical treatment.

[Hairy cell leukemia. I.--Clinical, biological and evolutive study on twenty-eight cases (author's transl)].

A clinical and laboratory evaluation of 28 patients with hairy cells leukemia is performed. Twenty-two had splenomegaly and all but one had a pancytopenia with 5 to 70% of hairy cells in blood. A tartrate-resistant acid phosphatase activity was positive in the hairy cells of 11 patients of 14 studied. In all patients a myelofibrosis and a leukemic infiltration were found in a bone-marrow biopsy of iliac crest. Hemodilution by splenomegaly, mild hemolysis and dyshematopoiesis were observed in 10 patients by a 51Cr or 59Fe isotopic exploration. In seven cases an immunological study of the hairy cells was performed, a high percentage of the leukemic cells of these 7 patients had polyclonal surface Ig but without resynthesis of monoclonal S Ig which is a feature usually associated with B lymphocytes. In the blood of these patients normal T and B lymphocytes were decreased. A splenectomy was done in 12 patients (43%) always for severe pancytopenia Splenectomy was not randomised. Spleen weights ranged from 1 085 to 3 600 g. In splenectomised patients the level of hemoglobin, segmented cells and thrombocytes was significantly higher after surgery. The survival rate is better in the splenectomised group (median survival 57 months) than in the non-splenectomised group (median survival 19 months). Infectious diseases were frequent in all patients but less after splenectomy. Fourteen patients died, 8 owing to pancytopenia.
