在体外循环期间，通过心内技术从4只感染犬中手术取出成年心丝虫。每只犬取出的蠕虫数量范围为12至14条。术后9个月的观察未发现活动性成年犬恶丝虫感染的临床证据，尽管在随访期间发现了一致的循环微丝蚴。没有明显的早期或晚期术后并发症。术后血液学和生化检查结果无异常。尸检时（人道处死后，手术后9个月），所有犬的心脏和肺动脉均无心丝虫成虫;未发现归因于残留感染的病理变化。
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.
