Abstract
We analyzed the incidence and management of major vascular complications at the arterial puncture site following diagnostic or interventional cardiac catheterization. 27387 cardiac catheterization procedures were performed for diagnostic (n = 19581) or interventional (n = 7806) purposes at our institution during a 7-year study period. A total number of 114 major vascular complications (0.42%) were identified. In 36 (0.13%) patients an arterial occlusion at the puncture site was detected, 34 patients (0.12%) had severe hematoma (blood transfusion or surgical repair necessary), 32 patients (0.12%) developed false aneurysms, 9 patients (0.03%) with av-fistulas and 3 patients (0.01%) had other complications. The following factors were predictive for a significant increase in the incidence of major vascular complications: Female gender, interventional catheterization using larger introducer sheaths and necessitating effective perioperative doses of heparine, and peripheral vascular disease. Operative repair was necessary in 62 patients (54%), 34 patients (30%) were treated conservatively. In 18 patients (17%) acute vascular occlusion could be managed by percutaneous transluminal balloon dilatation and intravascular thrombolysis of the obstruction, in 3 patients additional stent-implantation was necessary in the presence of a large occlusive dissection. Overall the rate of clinically significant major vascular complications is low. In the future a greater number of vascular complications at the entry site for cardiac catheterization will be treated with nonoperative methods (e.g. manual compression of pseudoaneurysms or catheter-based techniques for recanalization of acutely occluded vessels.
