Investigation of the popliteal artery branching patterns in Magnetic resonance angiography examinations: Kayseri Education and Research Hospital centre experience
Department of Radiology, Medical Health University Kayseri Education and Research Hospital, Kayseri, Turkey
To evaluate the variations of popliteal artery distal branching in examinations of lower extremity Magnetic resonance angiography (MRA).
Material and Methods
576 lower extremity MRA examinations that were done consecutively between years 2008 and 2012 in our hospital retrospectively evaluated. 151 examinations that were inappropriate quality for evaluation were excluded. 767 lower extremities belong to 425 patient included in our study. 342 lower extremities were evaluated bilaterally, 83 lower extremities were evaluated unilaterally.
The anatomical variations in the PA branching patterns were classified according to the system used by Kim et al.
The results determined from our study evaluated with other studies that researching PA distal branching variations with digital subtraction angiography and computed tomography angiography.
The most frequently seen pattern was type IA (normal pattern). Type IA was detected in 613 (80%) extremities. Variations in PA branching were depicted in 154 (20%) extremities.
733 (95.6%) limbs had a normal level of PA branching.
Type II variation that high division of the PA (at or above the level of the tibial plateau) was seen 34 (4.4%) extremities. Type III variation was detected in 87 (11.4%) extremities.
Of the 342 bilaterally evaluated patients, 251 (73%) had bilaterally symmetrical pattern. Type IA was the most frequently bilaterally symmetrical encountered pattern.
MRA examination can be used as an alternative to DSA for evaluation of PA branching patterns.
