RESUMO

Follow-up evaluation of 44 patients operated upon for renovascular hypertension between Jan. 1, 1969 and Dec. 31, 1978 indicated a 50% rate of cure, a 43% rate of improvement and a 2% operative mortality. The prognosis is much better for younger patients; for those under 35 years of age the cure rate was 100%. The renal vein renin level, although it is a measure of ischemic renovascular hypertension is not a precise criterion for predicting the results of surgical treatment.

RESUMO

The umbilical vein in adults is patent but collapsed. There is a membranous valve at its entrance into the left portal vein. Cannulation of the portal vein via the umbilical vein permits direct access to the portal system for portography and hepatography. This procedure was performed under local or general anesthesia in 30 patients and was successful in 22. It is useful in the investigation of patients with portal hypertension, and suspected intrahepatic tumours or abscesses. It gives excellent contrast visualization of the liver and definition of lesions as small as 1.0 cm. This technique is superior to both hepatic scanning and splenoportography.
