The Role of Multislice Computed Ttomography in Diagnostics and Estimation of the Treatment Quality of Popliteal Artery Aneurism

Purpose: to determine the role of multislice computed tomography (MSCT) in assessment of popliteal artery aneurysm and to estimate the quality of reconstructive operations, as well. Materials and Methods. 37 patients with popliteal artery ane urysm were investigated and treated surgically from 2006 to 2013. Patients age ranged from 20 to 71 years. Tactics of surgical treatment was based on Collor Doppler ultrasound, MSCT and in some cases on digital subtraction angiography datas. Results. 52 aneurysms of popliteal arteries were revealed in 37 patients. Aneurysms were unilateral in 22 (59.4%) cases and bilateral in 15 (40.6%). They were associated with aneurysms in other locations in 15 cases: with abdominal aorta - in 8 (21.6%) cases, with iliac arteries - in 3 (8.1%) cases, with femoral arteries - in 4 (10.8%) cases. Ligation of afferent and efferent vessels of aneurysm with autovenous grafting was performed in 12 (32.4%) cases; resection of aneurysm with autovenous grafting in 8 (21.6%) cases, dissection of aneurysm with autovenous grafting and coverage with duplication from aneurysmatic walls in 5 (13.5%) cases, endovascular grafting of aneurysm in 4 (10.8%) cases, ligation of afferent vessel of aneurysm in 1 (2.7%) case. Conclusion. As the standard method of diagnosis for all patients at revealing the popliteal artery aneurism, it is necessary to perform CD of aorta and the arteries of lower extremities on the whole length that helps to reveal accompanying aneurysms of abdominal aorta and of ilio-femoral segment. The advantage of MSCT to CD is the possibility of performing three dimentional (3D) images and enhanced images of tissues. This gives the opportunity for more detailed and precise study of topography of aneurism, involving vessels and tissues around it, also reveal the severity of lesions of the peripheral vascular bed and choosing optimal surgical treatment. The evaluation of efficiency of the surgical treatment and the adequacy of performed angioplasty or reconstruction of vessels is preferable to be assessed with CD. In case of some disorders, for more accurate evaluation of the vessels’ pathologies, examination should be added with MSCT.
