Obturator foramen bypass in the management of infected prosthetic vascular grafts
Insights
Obturator foramen bypass grafts are effective for lower extremity revascularization in cases of infected groin vascular grafts. This technique offers a durable solution for limb salvage, with high patency rates after surgery.
Area of Science:
- Vascular Surgery
- Infectious Disease Management
Background:
- Infected prosthetic vascular grafts in the groin present a significant challenge for lower extremity revascularization.
- Conservative treatments often fail to eradicate infection and can lead to complications like hemorrhage.
Purpose of the Study:
- To evaluate the efficacy and durability of obturator foramen bypass grafts for limb salvage in patients with infected groin vascular grafts.
Main Methods:
- Retrospective review of six obturator foramen bypass grafts performed in five patients.
- Grafts were used to revascularize the lower extremity after failure of conservative management for infected groin grafts.
Main Results:
- All patients had failed conservative measures, including antibiotic irrigation and abscess drainage.
- Five out of six obturator foramen bypass grafts remained patent at 11-26 months follow-up.
- This approach facilitated limb salvage in complex infectious groin complications.
Conclusions:
- The obturator foramen bypass graft is a durable and effective option for limb salvage in the context of infected groin prosthetic grafts.
- An aggressive surgical approach involving graft excision and bypass is recommended over conservative measures.
Abstract:
The obturator foramen bypass graft remains an excellent option for revascularizing the lower extremity when dealing with an infected prosthetic vascular graft in the groin. In this series, six obturator foramen bypass grafts were performed in five patients for infectious groin complications following vascular surgery. Conservative measures such as local antibiotic irrigation and abscess drainage designed to preserve the graft in situ had failed to eradicate the infection in all instances and was complicated by suture-line haemorrhage in three instances. An aggressive approach should be adopted, aimed at excision of the infected graft. The obturator foramen bypass graft remains a durable graft for limb salvage. Five out of six obturator foramen bypass grafts were patent after 11-26 months follow up.
