ABSTRACT Purpose: To determine the varients of profunda femoris artery [PFA] in origin, size and distance to origin by femoral artery CTA imaging. Materials and Method: Retrospectively review of 117 patients with femoral artery CTA, sites of origins were identified, diameter and distance of PFA Results: 234 femoral CTA. Shown 35.9% of PFA were originated from posterior site of Femoral artery, the second were originated from lateral site 33.33% then posterolateral origin was 27.78%. Most of MCFA (62.88%) and LCFA (67.09%) were originated from PFA. The diameter of PFA in Thais were 5.29 mm. and 5.49 mm. , mode of diameter of PFA was 5.1-6.0 mm [38.03%]. The Distance of PFA from the mid point of inguinal ligament to the origin of PFA was 34.29 mm. in the left PFA and 36.29 mm. in the right PFA. Conclusion: Variant of PFA in which the origin of PFA is posterior side of the femoral artery differed from Boonkham (1987) who studied in Thais cadavers. However most of PFA vessel was originated in lateral side of femoral artery in female both side and male left side

JIRTN 2011 vol.5 no.1 Introduction Type of anatomical variation in the origin of profunda femoris artery [PFA] is concern during puncture by seldinger method for cathererization in interventional procedure. Many minor and major complication is reported such as [3][7][9] arterial dissection, hematoma, arterio-thrombosis and pseudoaneurysm due to double side puncture technique or the tip of introducer invade the origin of PFA. Never report is described in the imaging and any suggestion in the performance. However the vascular disease in this location is rare [3][5][6][9] which only case reported. PFA had 4 type were described as type A: PFA arise from posterior side, type B: PFA arise from posterolateral side, type C: PFA arise from lateral side and type D: PFA arise from medial side, many PFA in cadavers is reported as [1][2][8][11]. Pioneer repost in PFA in Thai

established type B however the lastest report shown type A [1][12] instead however the report determined by high resolution imaging from living is still not. The purpose of our study was to determine sites of origins, diameter and distance of PFA

JIRTN 2011 vol.5 no.1 Bangkok, Thailand. Institutional ethical review board approval was accepted our study. Procedure Femoral artery CTA were done by CT 64 slices [LightSpeed,GE Medical] with iodinated contrast medium administration for 100 ml. of 370 mgI concentration by automatic injection at 4ml/sec, 300 PSI and serial scan with smart-prep technique. 1.25 mm. of slice thickness and interval then postprocessing with Advantage Workstation version 4.2 were set. Statistical Analysis We compared origin, size, distance in Femoral Artery CTA measured by 2 observers (interobserver reliability p
