The dimensions of the popliteal aneurysm and its relationship with the result of surgical repair

Abstract

BACKGROUND: Popliteal artery aneurysm (PAA) is the peripheral most frequent aneurysm. Its main complication is the thrombosis and acute limb ischemia (ALI). The majority of the studies analyzed the difference between the endovascular treatment (ET) and open repair (OR) and not factors related to the outcomes. The study aims to evaluate the relationship number of patent leg arteries (NPLA) for outflow and PAA anatomic aspects with primary patency (PP) and amputation-free survival (AFS) in patients treated electively.METHODS: This is a retrospective study of a cohort of 65 popliteal artery aneurysms (56 patients) treated from April 2010 to November 2019 in a single center. Inclusion criteria are all patients who underwent electively PAA OR.RESULTS: The mean age of the patients was 71.3±8.8 years, and most of the patients were male (91%). The incidence of hypertension, smoking, dyslipidemia, diabetes, coronary disease and stroke were 75.4%, 63.1%, 47.7%, 21.5% and 13.8%. The PAA mean diameter was 30,94±10.59 mm varying from 12.5 to 57 mm. The mean of the lenght was 63.4±34.06 mm, and in 46% PAA reach the third segment of PAA (P3). There was no relantionship between the variables diameter and extension with AFS and PP, even as NPLA and PP. Nonetheless, considering AFS, poor runoff were related to a worse result.CONCLUSIONS: We conclude that dimension and length of PAA had not correlation with PP and AFS, nonetheless poor runnof worsens AFS in PPA OR electively.
