Abstract

Objective: The purpose of this study was to compare outcomes after endovascular repair (ER) and contemporary open repair (OR) of popliteal artery aneurysms (PAAs). Methods: Clinical data of PAA patients treated between 2005 and 2012 were reviewed. Primary end points were major adverse events (MAEs) including mortality, major amputation, patency, complications, and reinterventions. Results: A total of 149 PAAs were treated in 120 patients (mean age, 74 ± 10 years). ER was performed in 42 limbs of 35 men (mean age, 81 ± 6.5 years), in 32 electively and in 10 emergently. Technical success was 98%. The 30-day MAEs were more frequent after emergent repair (50% vs 9%; odds ratio [OR], 9.67; 95% confidence interval [CI], 1.74-54; P =.01); mortality and amputation rate was 0% after elective repair, 20% after emergent repair. Mean follow-up was 2.6 years (1 month-6.5 years); 3-year freedom from MAEs was lower after emergent repair than after elective repair (40% vs 66%; hazard ratio [HR], 3.13; 95% CI, 1.10-8.85; P =.03). OR was performed in 107 limbs of 91 patients (90 men; mean age, 71 ± 9.6 years), in 93 electively and in 14 emergently. The 30-day MAEs were more frequent after emergent repair (43% vs 5%; OR, 13; 95% CI, 3.29-53; P <.001); mortality was 1% after elective repair, 0% after emergent cases. Amputation rate was 0% for both elective and emergent repairs. Mean follow-up was 3.8 years (1 month-8.4 years); 3-year freedom from MAEs was lower after emergent repair (50% vs 80%; HR, 3.78; 95% CI, 1.55-9.20; P =.003). The 30-day MAE rates were equivalent between ER and OR independent of urgency of repair (elective: OR, 1.82; 95% CI, 0.41-8.09; P =.43; emergent: OR, 1.33; 95% CI, 0.26-6.81; P =.73). In elective interventions, ER had a trend to decreased freedom from MAEs (66% vs 80% at 3 years; HR, 1.93; 95% CI, 0.92-4.07; P =.08); freedom from reintervention was lower after ER (72% vs 88%; HR, 2.41; 95% CI, 1.02-5.70; P =.046). In emergent interventions, 1-year freedom from MAEs was similar (40% vs 50%; HR, 1.36; 95% CI, 0.49-3.74; P =.55). Emergent ER and poor runoff predicted MAEs. Conclusions: Our study failed to prove the superiority of ER over OR. If anatomy is suitable, ER of PAA in the elderly and high-risk patients is justified. For emergent PAA repairs, MAEs are frequent after both ER and OR; ER has not changed the severe prognosis of acute limb ischemia from PAA. A multicenter randomized controlled trial of PAA patients with acute presentation is warranted.
