Problems related to previous thrombendarterectomy of the aorto-ilio-femoral arterial segment
1Department of Surgery, Trondheim University Hospital, Norway.
Insights
Early complications of aorto-ilio-femoral thrombendarterectomy include occlusion and bleeding. Late reobstruction, often due to atherosclerosis, may require bypass grafting or percutaneous transluminal angioplasty (PTA).
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
- Surgical Complications
Background:
- Aorto-ilio-femoral thrombendarterectomy is a procedure to remove plaque from arteries.
- Early and late complications can arise, impacting patient outcomes.
- Understanding these complications is crucial for surgical planning and patient management.
Purpose of the Study:
- To discuss technical aspects for preventing early complications.
- To outline management strategies for late complications like reobstruction.
- To compare surgical approaches for redo procedures.
Main Methods:
- Review of technical considerations for preventing early postoperative issues (occlusion, bleeding, emboli).
- Discussion of causes and management of late complications (reobstruction, sexual dysfunction, aneurysm).
- Evaluation of redo aorto-ilio-femoral reconstruction, favoring bypass grafting and laparotomy, with consideration for ureteral stents and profunda artery reconstruction.
Main Results:
- Early complications are primarily occlusion, bleeding, and emboli, preventable with specific technical details.
- Late reobstruction, often from atherosclerosis progression or technical failure, is a significant concern.
- Bypass grafting is preferred for redo procedures; percutaneous transluminal angioplasty (PTA) is an option for localized obstructions.
Conclusions:
- Meticulous surgical technique is vital for minimizing early complications.
- Management of late reobstruction often involves bypass grafting or, in select cases, PTA.
- Redo aorto-ilio-femoral reconstruction requires careful planning, including ensuring adequate run-off and potentially supplementing with profunda artery reconstruction.
Abstract:
Early postoperative problems following aorto-ilio-femoral thrombendarterectomy include occlusion, bleeding and emboli. Technical details important for the prevention of these complications are discussed. Late problems include reobstruction, sexual dysfunction and aneurysm formation, the last complication being unusual following thrombendarterectomy. Late reobstruction is usually caused by progression of atherosclerosis and technical failures. Bypass grafting using synthetic material is usually the preferred method in redo aorto-ilio-femoral reconstruction since extensive dissection of the arteries is then avoided. We prefer a regular laparotomy for these operations. It might be an advantage to introduce ureteral stents making it easier to identify the ureter which may be surrounded by scar tissue following previous dissection. The creation of sufficient run-off is important. In several cases the procedure must therefore be supplemented with a profunda artery reconstruction. In case of localized and moderate obstruction PTA may be indicated for the relief of recurrent arterial obstruction following thrombendarterectomy.
