WAKASSA, Tais Bugs et al. Follow-up of the aneurysmal sac after exclusion and bypass of popliteal artery aneurysms. Clinics [online]. 2006, vol.61, n.2, pp.107-112. ISSN 1807-5932.

Popliteal artery aneurysms are frequent and may lead to thromboembolic events and limb loss. PURPOSE: To evaluate clinical and ultrasonographic follow-up of patients who underwent exclusion of a popliteal artery aneurysm using the technique proposed by Edwards. METHODS: Data of all patients who underwent surgery to repair a popliteal artery aneurysm at Hospital das Clinicas, the São Paulo University Medical School between 1996 and 2004 were reviewed. Inclusion criteria were repair with aneurysm exclusion and bypass using the technique proposed by Edwards, as well as the existence of preoperative and postoperative measurements of the aneurysmal sac. RESULTS: Data of 16 patients who underwent 20 procedures for popliteal artery aneurysm exclusion and bypass were available to analysis. The preoperative diameter of the popliteal artery aneurysms ranged from 1.3 cm to 6.1 cm (mean = 3.1 cm). Patients underwent duplex ultrasound scanning 1 month to 7 years after surgical repair. Follow-up of the 20 cases revealed that 10 aneurysms exhibited decreased mean transverse diameters, ranging from 0.2 to 2.3 cm, while 7 had increased in diameter, ranging 0.3 to 3.3 cm, and 3 remained unchanged. Flow was observed only in 5 outo f the 20 procedures, 3 of which (60%) had increased diameters. CONCLUSION: Although exclusion is a widely accepted procedure for the repair of popliteal artery aneurysms, data in the literature and the results of this study, which did not include cases of rupture or compression, suggest that strict follow-up of patients who undergo aneurysm exclusion is necessary.
