Özet
Popliteal artery aneurysms (PAA) are the most common (0.1-2.8%) peripheral artery aneurysms. Although popliteal
artery aneurysms are rare, they can cause serious complications. One of the reasons for the surgical treatment of PAA is
thromboembolism and its complications and another reason for surgery is to prevent rupture by enlarging the aneurysm itself.
82-yr male patient admitted to the emergency service with the development of sudden pain, coldness and paleness in right
lower extremity. The patient was taken into an emergency operation, as a PAA with a size of 8.6x5.5x4.4 cm was observed in
the Doppler USG and distal flow was not detected due to thromboembolism. PAA was exposed through an incision applied
to the popliteal fossa with a posterior approach. The aneurysm was fully explored, embolectomy was performed on anterior
tibial artery (ATA), peroneal tibial artery (PETA) and posterior tibial artery (PTA) with a fogarty catheter. Then, the aneurysm
was excised and 10 mm polytetrafluoroethylene (PTFe) graft was placed in its place. The proximal part distal to the popliteal
artery and the peronal truncate were anastomosed end-to-end. ATA was anastomosed to graft with an end-to-side anastomosis.
Postoperative pulses were palpable in the dosalis pedias artery and PTA.
Limb loss was demonstrated at rate of 20-59% and mortality rate 5.4-11.8% in patients who underwent emergency surgery with
critical ischemia. Surgical approach is performed posteriorly or medially. Endovascular approaches are also available, but longterm results of endovascular approach are required, as stent fractures secondary to flexion movement of the knee joint may
occur. For this reason, surgical procedures are still the gold standard.
