RESUMO
BACKGROUND AND OBJECTIVE: It is common clinical practice to perform an arteriotomy for the endovascular treatment of infrarenal and thoracic aortic aneurysms. Instead we used the percutaneous endovascular Perclose device to perform the aneurysm repair without arterial cut-down. PATIENTS AND METHODS: The Perclose device contains four needles with two suture loops for closing the femoral artery access site. The sutures were deployed after the arterial puncture, before introduction of sheaths (diameter 12 - 27 F = 4 - 9 mm). After the procedure the sutures were used to close the puncture site. We attempted to achieve hemostasis with the Perclose system in 104 femoral arteries in 60 patients (7 females, mean age 69 +/- 12 years). The mean vessel diameter was 10 +/- 2 mm. RESULTS: The percutaneous graft implantation was successfully achieved in 58 of 60 patients. The graft could not be forwarded into the aorta in two cases because of calcified iliac arteries. The Perclose suture technique was successfully used in 97 femoral arteries. In one case a false aneurysm developed and in another case a secondary hemorrhage occurred. Seven patients needed additional manual compression to achieve complete hemostasis. A surgical repair was not necessary. The time to hospital discharge ranged from 4.5 hours to 32 days (median: 18 hours). 20 patients stayed longer than 24 h in the hospital, only 2 of them for reasons related to the puncture site. CONCLUSION: Closing the access site with the Perclose system is technically feasible and effective, even with large sheaths up to 27 F = 9 mm. This technique reduces the invasiveness of the endovascular repair of aortic aneurysms and decreases the length of hospital stay, i. e. it allows treatment in outpatients.
