Abstract

BRAGA, André Felipe Farias et al. Open versus endovascular surgery for treatment of popliteal artery aneurysms: 5 years’ experience at the HCRP-FMRP-USP. J. vasc. bras. [online]. 2015, vol.14, n.4, pp.297-304. ISSN 1677-5449.  http://dx.doi.org/10.1590/1677-5449.02715.

Background

popliteal artery aneurysms (PAAs) account for 70% of peripheral aneurysms. Surgery is indicated for aneurysms that have diameters greater than 2.0 cm or are symptomatic. Repair can be achieved by conventional surgical techniques or using endovascular methods, which are becoming increasingly popular, but for which there is not yet a consensus on indications.

Objective

To describe the experience of treating PAAs at the vascular and endovascular surgery department of the Hospital das Clínicas de Ribeirão Preto, affiliated to the Universidade de São Paulo (Brazil).

Method

A review was conducted of cases of conventional and endovascular repair of PAAs over the last 5 years, analyzing demographic data, comorbidities, surgical indications, preoperative and early and late postoperative complications, length of hospital stay and patency, during follow-up of up to 1 year.

Results

During the period analyzed, ten endovascular surgeries (ES) and 21 open surgeries (OS) were performed. The ES group exhibited a higher frequency of comorbidities. There was a higher frequency of symptomatic patients in the OS group (85%) than in the ES group (40%). The ES group exhibited a lower number of clinical and surgical complications. There were no statistical differences between the groups in terms of age or length of hospital stay. Primary patency at 1 year was 80% in the ES group and 75% in the OS group.

Conclusions

Endovascular treatment for PAAs offers good results in terms of patency, with acceptable complication rates, in patients with high surgical risk and favorable anatomy. Controlled studies are therefore warranted to validate the endovascular technique and afford it the status of an alternative procedure for use in selected cases.
