“…This had already been reported by Beregi et al [21]. However, new advances in multi-row detector technology, especially 16-row CT scans as used in our study, allows larger volume acquired with a high resolution at similar or shorter acquisition times than the CT scans reported in previous studies.…”

“…Thus, they recommended long-term surveillance of all PAAs with contrast enhanced CT or Doppler ultrasound (DU). Few reports exist in the literature about CT reliability in detecting popliteal aneurysmal disease, especially using multi-slice CT (MSCT) angiography [20,21]. To our knowledge, none of them evaluated the potential of CT in the post-operative surveillance of excluded PAAs.…”

Long-term follow-up of surgically excluded popliteal artery aneurysms with multi-slice CT angiography and Doppler ultrasound

The purpose of this study was to evaluate the role of multi-slice computed tomography (MSCT) angiography in the follow-up of popliteal artery aneurysms (PAAs) that have been operated on. Aneurysm exclusion and progression, graft patency and graft-related complications were analyzed. Fourteen patients with 21 surgically excluded PAAs were evaluated with MSCT angiography with slice thickness of 1.25 mm. The mean follow-up time was 67 months. MSCT demonstrated blood flow in six nonexcluded PAAs (24%), with an average increase in the diameter of 21 mm over time. Fifteen PAAs demonstrated no blood flow and revealed an average decrease of 7 mm in diameter. The origin of this residual perfusion was demonstrated, and collaterals were involved in five of six non-excluded PAAs. In addition, MSCT demonstrated three graft stenoses. Furthermore, two occluded grafts were visualized. Twenty-four percent of the patients after surgical exclusion of PAAs revealed residual perfusion within the aneurysmal sac during follow-up, with a significant increase in the aneurysmal size with MSCT. Moreover, evaluation of the graft patency could also be done as could demonstration of anastomotic abnormalities. Thus, MSCT might be considered as a new tool to evaluate residual collateral feeding of popliteal aneurysmal sac and could be useful in identification and localization of feeding vessels.

“…It provides detailed information on the wall and diameter of the artery and relation of the artery to adjacent structures but it too uses contrast material and ionizing radiation. 5 MRI and MR angiography have emerged as promising imaging modalities for the diagnosis of PAES, and have the advantage of multiplanar capabilities, nonionizing radiation, high soft-tissue contrast and avoidance of iodinated contrast material. They can be undertaken at rest and during active manoeuvres, and thus show functional entrapment if present.…”

Popliteal artery entrapment syndrome is a rare abnormality of the anatomical relationship between the popliteal artery and adjacent muscles or fibrous bands in the popliteal fossa. The following is a case report of a 19 year old female, in whom popliteal artery entrapment syndrome was diagnosed, and successfully treated surgically. A review of literature is also presented and provides details on how PAES is classified, diagnosed both clinically and radiologically, and treated surgically.

1Lietuvos sveikatos mokslų universiteto Širdies, krūtinės ir kraujagyslių chirurgijos klinika SANTRAUKAReikšminiai žodžiai: arterijų pažeidimas, kompiuterinės tomografijos angiografija, invazinė angiografija. Darbo tikslas. Nustatyti, ar 320 pjūvių kompiuterinė tomografijos angiografija yra patikimas ir tikslus tyrimas nustatant arterijų stenozės laipsnį, esant periferinių arterijų ligai apatinėse galūnėse. Tyrimo medžiaga ir metodai. Įtraukimo kriterijai: pacientai, sergantys periferinių arterijų liga, kuriems atlikta 320 pjūvių kompiuterinės tomografijos angiografija ir invazinė angiografija per mažiau nei 2 savaičių laikotarpį, kuriems tuo laikotarpiu nebuvo taikytas operacinis ar intervencinis gydymas; pakankamos kokybės kompiuterinės tomografijos angiografijos vaizdai. Rezultatai. Įtraukimo kriterijus atitiko ir buvo vertinami 275 apatinių galūnių arterijų segmentai. Invazinės angiografijos tyrime 0-49 proc. stenozė nustatyta 161 segmente (58,5 proc.), 50-69 proc. stenozė -14 segmentų (5,1 proc.), 70-99 proc. stenozė -22 segmentuose (8 proc.), 100 proc. okliuzija -78 segmentuose (28,4 proc.). Kompiuterinės angiografijos tomografijos tyrime 0-49 proc. stenozė nustatyta 162 segmente (58,9 proc.), 50-69 proc. stenozė -9 segmentuose (3,3 proc.), 70-99 proc. stenozė -32 segmentuose (11,6 proc.), 100 proc. okliuzija -72 segmentuose (26,2 proc.). 320 pjūvių kompiuterinės tomografijos angiografijos rezultatai, palyginti su invazine angiografija, sutapo 216 segmentų (78,5 proc.), kappa = 0,63. 320 pjūvių kompiuterinės tomografijos angiografijos jautrumas ir specifiškumas diagnozuojant kliniškai reikšmingą stenozę (> 50 proc.) buvo atitinkamai 90,4 proc. ir 94 proc. 320 pjūvių kompiuterinės tomografijos angiografijos jautrumas nustatant didesnę nei 70 proc. stenozę buvo 91 proc., specifiškumas -93 proc. Išvados. Mūsų tyrimo rezultatai parodė, kad apatinių galūnių 320 pjūvių kompiuterinės tomografijos angiografija nustatyti pakitimai atitiko invazinės angiografijos rezultatus. Nustatyta, kad 320 pjūvių kompiuterinės tomografijos angiografija yra jautrus ir specifiškas tyrimas nustatant arterijų stenozes. ABSTRACTKey words: arterial disease, computed tomography angiography, invasive angiography. Objective. To determine whether 320 slices computed tomography angiography is a reliable test when determining the degree of arterial stenosis in case of peripheral artery disease in lower extremities. Materials and methods. Patients with peripheral artery disease who had 320 slices computed tomography angiography and invasive angiography performed in less than two weeks, to whom surgical or interventional treatment was not applied; computed tomography angiography images of sufficient quality.
