[Evaluation of surgical renal revascularization in renovascular arterial hypertension. Measurement by 99m Tc DTPA scintigraphy].

The effects of surgical renal revascularization on both hypertension and kidney function was assessed in 16 patients with renovascular hypertension (14 unilateral). We have taken a special interest to the split renal function studied with DTPA renogram. The function of the operated kidney was improved in 9 patients and not improved (worsened or unchanged) in 7.

[Technics for the exploration of pulmonary arteriovenous shunts in liver cirrhosis. Apropos of 2 cases].

Pulmonary arterio-venous shunts represent a rare cause of hypoxia in cirrhosis. We present two cases, the first was an alcoholic cirrhotic with anthracosilicosis. This patient rapidly developed a picture of significant hypoxaemia with a raised alveolar-arterial oxygen gradient.
