Duodenal ulcer haemorrhage treated by embolization : results in 28 patients


Price: €10,00

Background : To assess the effectiveness and prospects of transcatheter gastroduodenal artery embolization in the control of massive duodenal bleeding and to relate our experience. Methods of study : The study is based on the retrospective analysis of 165 patients with endoscopically detected bleeding duodenal ulcer who presented between 1991-1998. 28 patients were considered eligible for endovascular treatment either at initial presentation or following hemorrhage recurrence after endoscopic therapy. Results : Technical failure was noted in 3 cases, thereafter treated by surgery. In the other 25 patients, embolization was performed : bleeding recurrence occurred in 7 cases. Four were treated only endoscopically. One was reembolized and the last two were treated by surgery. In 6 cases, a coaxial technique was used (guiding catheter in 2 and 3F microcatheter in 4). No complication related to the catheterization was observed. Conclusion : Transcatheter embolization of the gastroduodenal artery appears to be an efficient procedure even in the absence of active bleeding at the time of the procedure. Failure and recurrence rates can be reduced by using a coaxial technique in the uneasy cases. Embolization seems to have a low recurrence rate and a very low complication rate.

Interest of the association clonidine-spironolactone in cirrhotic patients with ascites and activation of sympathetic nervous system


Price: €10,00

Background : The aim of this study was to examine the effects of spironolactone, clonidine and the association of clonidine-spironolactone on renin-aldosterone and sympathetic systems, renal function, systemic hemodynamics and mobilization of ascites in 32 alcoholic cirrhotic patients with marked increase in sympathetic system. Methods : Measurements were taken before and after an 8-day treatment with spironolactone (200 mg/day), after an 8-day treatment with clonidine (0.150 mg/day) and 10 days after adjunction of spironolactone (200 mg/day) to clonidine. Results : Three patients abandoned the treatment or were excluded because lack of compliance. Spironolactone alone induced an increase in renin-aldosterone and sympathetic systems without any remarkable increase of natriuresis and body weight loss. Given for 8 days, clonidine alone induced a significant decrease in plasma norepinephrine associated with a significant increase in glomerular filtration rate without effect on natriuresis. In contrast, 10 days after adjunction of spironolactone to clonidine, plasma renin and aldosterone significantly decreased, natriuresis increased (from 7.4 ± 0.7 to 41.6 ± 3.2 mEq/24h) and body weight decreased (from 66.03 ± 2.3 to 63.5 ± 2.3 kg) without adverse effects. Conclusion : In cirrhotic patients with ascites and marked activation of sympathetic nervous system, spironolactone (200 mg/day) is unable to mobilize ascites. In these patients, after 8 days, clonidine decreases sympathetic activity, increases glomerular filtration rate and after 18 days, decreases plasma renin and aldosterone concentrations allowing a better action of spironolactone. The association clonidine-spironolactone enhances natriuresis and body weight loss. [Product Details...]
