Small stainless steel coils have been developed for transcatheter vascular occlusion procedures. The coils can be passed through a 5-French polyethylene catheter, extending the clinical applications of coil occlusion procedures for small and/or tortuous vessels. Two cases describing the use of these coils are reported.
Fistulas were surgically created between the carotid artery and jugular vein in dogs. They were successfully occluded by means of transcatheter placement of stainless steel coils with attached woolen strands. Angiographic studies performed prior to, immediately after, and 4 weeks after occlusion were used to evaluate the efficacy of the procedure. Specimens excised 4 weeks after occlusion revealed fibrotic encasement of the coil in the fistula, forming a permanent occlusion. The technique has clinical application, and suggestions concerning its clinical use are presented based on information gained from the animal study.
The stainless steel coil has been utilized for permanent intravascular occlusion of the proximal portion of the renal, hepatic, splenic, and internal iliac vessels. This therapeutic approach has been successful in the management of renal arteriovenous fistulas, renal carcinomas, neoplasms of the liver, giant cell tumors of the sacrum, and in hypersplenism. The techniques involved and clinical uses are discussed.
