Objective: The purpose of this study was to examine the patterns of injury and the strategies of surgical repair of iatrogenic vascular injuries from a percutaneous vascular suturing device after arterial cannulation. Methods: We retrospectively reviewed the clinical experience from an academic vascular surgical practice over a 2-year period. The subjects were patients undergoing vascular repair of iatrogenic vascular injury after deployment of a percutaneous vascular suturing device. Interventions were direct repair of arterial injury (with or without device extraction) or arterial thrombectomy and repair. The main outcome variables included patterns of arterial injury, magnitude of arterial repair, limb salvage, hospital stay, and perioperative mortality and morbidity rates. Results: From August 1998 through August 2000, eight patients (4 men, 4 women; median age, 55 years; range, 44-80 years) required vascular operations for complications of percutaneous suturing devices after diagnostic (2) or therapeutic (6) arteriograms through a transfemoral approach. Complications included four pseudoaneurysms (1 infected) due to arterial tear from suture pull through, two entrapped closure devices due to device malfunction, and two arterial thromboses due to narrowing/severe intimal dissection. All patients required operative intervention. Direct suture repair with or without device removal was performed in five patients, arterial debridement with vein patch angioplasty in one patient, and arterial thrombectomy and vein patch angioplasty in two patients. There were no perioperative deaths. The median hospital stay was 5 days (range, 2-33). Limbs were salvaged in all patients with a mean follow-up of 4.8 months (range, 1-13). Conclusions: Although abbreviated postangiography recovery periods and early ambulation have motivated the widespread use of percutaneous suturing devices, the infrequent occurrence of vascular injuries produced by these devices can be significantly more challenging than simple acute pseudoaneurysms or hemorrhage. In addition, thrombotic complications have a small but finite risk of limb loss. (J Vasc Surg 2001;33:943-7.)
