Adult heartworms were surgically removed from 4 infected dogs by use of intracardiac techniques during cardiopulmonary bypass. The number of worms removed ranged from 12 to 14 per dog. Observation for 9 months after surgery gave no clinical evidence of active adult heartworm infection, in spite of the consistent finding of circulating microfilariae during the follow-up period. There were no significant early or late postoperative complications. Results of postoperative hematologic and biochemical studies were unremarkable. At necropsy (following euthanasia, 9 months after surgery) the heart and pulmonary arteries of all dogs were free of adult heartworms; pathologic changes attributable to residual infection were not found.
在体外循环期间，通过心内技术从4只受感染的犬身上手术摘除了成虫心丝虫。每只犬摘除的心丝虫数量为12至14条。术后观察9个月，尽管在随访期间持续发现循环微丝蚴，但未发现成虫心丝虫感染活跃的临床证据。术后无明显的早期或晚期并发症。术后血液学和生化研究结果无异常。尸检时（术后9个月安乐死后），所有犬的心脏和肺动脉均未发现成虫心丝虫；未发现残留感染引起的病理变化。
