BACKGROUND: Popliteal artery aneurysm (PAA) is the most common peripheral aneurysm. When left untreated, it is associated with significant morbidity and limb loss. Here, we present our experience and outcome of endovascular repair of popliteal artery aneurysm with Gore Viabhan stent.
METHODS: This was an observational study of 68 patients (79 limbs) to determine primary patency in patients with PAA who underwent endovascular repair between 2011–2016.
RESULTS: Males accounted for approximately 92% of the population with an average age of 73 years. The majority of subjects were smokers and hypertensives with a mean follow-up of 2.5 years. Primary patency rate was 73.4% with a 12-month primary patency rate of 91.1%. Reintervention was necessary for 19.0% of the population, with 9% occurring within the first year. Index intervention for acute ischemia was predictive of 12-month post-operative stenosis (p = .017). Smoking was the strongest risk factor for restenosis followed by endoleak. Refer to Table 1 for a more detailed analysis.
CONCLUSIONS: Endovascular repair of PAA with Gore Viabhan stent graft is an effective and durable treatment strategy. We report newly identified, avoidable predictors of endoprosthesis occlusion like smoking, and acute limb ischemia during index intervention.
