The feasibility of endovascular diathermic vessel occlusion (EDVO) is demonstrated in canines. The technique was standardized by measuring current flow through a monopolar intravascular electrode. Between 150 and 350 mA were applied to a spider-shaped intravascular electrode producing venous occlusion without perivascular damage. With further refinements in instrumentation, EDVO holds promise as a quick, safe method of therapeutic vascular occlusion that may eventually be applied clinically for spermatic vein occlusion.
血管内热凝血管闭塞术(EDVO)在犬类动物中已证实其可行性。该技术通过测量流经单极血管内电极的电流进行标准化。向蜘蛛形血管内电极施加150至350毫安的电流,可实现静脉闭塞且不会造成血管周围损伤。随着仪器设备的进一步改进,EDVO有望成为一种快速、安全的治疗性血管闭塞方法,最终可能应用于临床精索静脉闭塞。
