Popliteal aneurysms. A clinical appraisal

Area of Science:

• Vascular Surgery
• Vascular Medicine
• Medical Diagnostics

Background:

• Popliteal aneurysms are a significant vascular condition.
• Aneurysms can develop synchronously or metachronously in multiple locations.
• Untreated popliteal aneurysms carry a risk of acute limb-threatening complications.

Purpose of the Study:

• To analyze the clinical presentation, management, and outcomes of popliteal aneurysms.
• To evaluate the incidence of associated aneurysms and limb salvage rates.
• To determine the optimal surgical approach for popliteal aneurysms.

Main Methods:

• Retrospective analysis of 49 popliteal aneurysms in 34 patients treated between 1950 and 1980.
• Review of patient records for aneurysm characteristics, clinical presentation, and treatment outcomes.
• Diagnostic methods included physical examination, arteriography, and ultrasonography.

Main Results:

• 88% of aneurysms and 40% of patients had associated aneurysms.
• 22% of patients were asymptomatic; 36% presented with claudication.
• One-third of patients experienced acute limb-threatening complications (thrombosis, embolization, rupture).
• Limb salvage rates were lower in cases of thrombosis (45%) and embolization (75%).

Conclusions:

• Proximal and distal aneurysmal ligation with reversed saphenous vein bypass is the preferred surgical procedure.
• Surgical repair of asymptomatic popliteal aneurysms is indicated due to the risk of complications and superior patency rates.
• Early diagnosis and intervention are crucial for improving limb salvage in popliteal aneurysm patients.
