Embolic and occlusive complications from thrombosed femorofemoral grafts
Insights
Acute arterial occlusions linked to thrombosed femorofemoral grafts pose a risk to limb survival. Prompt graft intervention or removal is crucial to prevent embolic and occlusive complications.
Area of Science:
- Vascular Surgery
- Cardiovascular Medicine
Background:
- Femorofemoral grafts are used to bypass arterial blockages in the legs.
- Thrombosis (clot formation) within these grafts can lead to serious complications.
Observation:
- Five cases of acute arterial occlusion due to thrombosed femorofemoral grafts were identified.
- Four occlusions were linked to graft trauma and suspected embolism.
- All patients exhibited thrombus extending from the graft into the femoral artery.
Findings:
- Thrombosed femorofemoral grafts can cause limb-threatening arterial occlusions.
- Embolism is a potential complication, especially following graft trauma.
- Thrombus extension into the femoral artery poses a significant risk.
Implications:
- Graft thrombectomy should be considered when feasible.
- If thrombectomy fails or is not performed, graft detachment or excision is recommended.
- Prophylactic removal of thrombosed grafts can prevent further embolic and occlusive events.
Abstract:
Five episodes of acute arterial occlusions associated with thrombosed femorofemoral grafts are reported. Four of these occlusions were directly associated with trauma to the graft and were thought to be embolic. All patients had thrombus extending from the thrombosed graft into the femoral artery, threatening the survival of the lower extremity. We recommend that when a graft thrombectomy is not performed, or is not successful, the thrombosed femorofemoral graft should be detached or excised as prophylaxis against embolic and occlusive complications.
