Long-term surgical outcome of closed mitral commissurotomy.

Seven hundred and fifty-four patients who underwent closed mitral commissurotomy (CMC) between 1958 and 1993 (71% female, 29% male; mean age 39 years) for acquired mitral stenosis were reviewed postoperatively. Particular attention was given to those patients who later required mitral valve replacement (MVR). The total follow up experience was 9,607.

Pathogenesis of aortoenteric fistula. An experimental study.

The pathogenesis of aortoenteric fistulas was studied in the experimental laboratory. In 23 dogs patch of woven dacron was interposed in the anterior wall of the infrarenal abdominal aorta. In two groups (I and II), the serosa denuded duodenal wall was sutured to an opening of the proximal anastomosis--creating a pseudoaneurysm--, with induction of staphylococcal bacteremia, without (group I) and with simultaneous administration of methicillin (group II) pre and postoperatively.

[Rare primary localizations of Echinococcus cysticus].

Seven cases of unusual location of echinococcus cysts are described. Three of them were located in the muscles, three in the subcutaneous tissue and one in a retroperitoneal position.

Inferior vena cava thrombosis due to migration of retained functionless pacemaker electrode.

Thrombosis of the inferior vena cava due to migration of a pacing wire has not been published previously. We describe such a complication due to migration of a retained pacemaker electrode. The distal cut end of the wire was found looped at the level of thrombosis of the inferior vena cava.
