Insights
Balloon catheter thrombembolectomy for arterial occlusion has a 4.3% complication rate, including perforations, dissections, and aneurysms. Proper technique is crucial to minimize these risks during the procedure.
Area of Science:
- Vascular Surgery
- Interventional Radiology
- Cardiovascular Medicine
Background:
- Balloon catheter thrombembolectomy is a common procedure for arterial occlusion.
- Understanding complication rates and types is essential for improving patient outcomes.
- Previous studies have highlighted various complications associated with this intervention.
Purpose of the Study:
- To analyze the incidence and types of complications in a large series of balloon catheter thrombembolectomy procedures.
- To identify potential causes and contributing factors to these complications.
- To emphasize the role of intraoperative angiography in managing complications.
Main Methods:
- Retrospective analysis of 717 cases undergoing balloon catheter thrombembolectomy for arterial occlusion.
- Classification of complications into predefined groups.
- Review of procedural details and intraoperative findings.
Main Results:
- A total of 31 complications (4.3%) were recorded in 717 cases.
- Complications included perforations/ruptures (2.2%), dissections (1.4%), AV-fistulas (0.3%), and aneurysms (0.4%).
- Intimal lesions and catheter failures were also noted; inadequate handling is suspected as a primary cause.
Conclusions:
- Balloon catheter thrombembolectomy carries a low but significant complication rate.
- Meticulous technique and handling are paramount to prevent adverse events.
- Intraoperative angiography is vital for timely recognition and management of complications.
Abstract:
Complications related to balloon catheter thrombembolectomy in 717 cases of arterial occlusion occurred in 4.3% (= 31) and are classified in 6 groups: 16 perforations resp. ruptures (2.2%), 2 AV-fistulas (0.3%), 10 dissections (1.4%), 3 aneurysms (0.4%), intimal lesion and catheter failure. Inadequate handling is probably responsible in the majority of cases. Intraoperative angiography usually permits to recognize the complication and displays the details required for additional procedures.
