Tortuous treatment process of a complex femoral pseudoaneurysm following atrial fibrillation ablation: a case report

Abstract

Abstract Background Although the rate of vascular complications following catheter ablation has been decreasing in the past 10 years, it remains a common and thorny problem in clinical settings. For the majority of iatrogenic pseudoaneurysms (PSAs), non-surgical therapeutic approaches such as ultrasound-guided compression repair (UGCR) and ultrasound-guided thrombin injection (UGTI) have been used as first-line regimens. However, suitable treatment for PSA mainly depends on the characteristics of the PSA. Case summary This report presented the case of a 75-year-old woman who suffered from a beaded multi-chamber femoral PSA combined with arteriovenous fistula between the superficial femoral artery and the common femoral vein following radiofrequency ablation of atrial fibrillation. The treatment process of the PSA was tortuous. After a UGCR attempt, the PSA was not occluded. The UGTI successfully clotted the superficial and middle chambers of the PSA. After repeat UGCR, the residual deep chamber of the PSA was expanded, and the skin deteriorated. The complicated PSA was finally treated with surgical repair. Discussion Appropriate treatment for PSA depends on the anatomical characteristics of the PSA and indications of various treatment measures.
