Branching pattern of the femoral artery at the femoral triangle: a cadaver study

Abstract

The proper knowledge of the course and ramification of the blood vessels of the lower limbs is very important for surgeons and interventional radiologist. This is because the lower limb arteries are commonly involve with peripheral occlusive arterial diseases and the femoral artery at the femoral triangle is widely used for certain clinical procedures like arterial catheterization. Although there are several studies on the branching pattern of the femoral artery in the femoral triangle the Sri Lankan studies are spars.

Origin of profunda femoris artery and its circumflex femoral branches: anatomical variations and clinical significance

“…In disagreement with the results of present study, different ranges of the distance were obtained in literature: 31-40 mm in right limbs and 41-50 mm in left limbs [8]; 55 mm on right side and 45 mm on left side [17]; commonly between 31-40 mm [2] and its mean was 42 mm [15], 44 mm [18], 32 mm [16] and its normal range was 35-40 mm [21]. Awareness of the original site and distance of PFA is important for prevention of iatrogenic injuries that may occur during the diagnostic or therapeutic procedures in the femoral region.…”

“…In agreement with the results of present study, Dixit et al [8] found this origin pattern in 28.5% of the limbs. However, a higher incidence rates were recorded in the literature, 53.3% [11], 46.9% [15], 46.1% [17] and 44.6% [20]. Moreover, the PFA originated from the lateral aspect of FA in 20% of the limbs with no side or sex differences in the present study and this in agrees with Siriporn et al [20] who found this pattern in 21.4% in Thailand population.…”

“…These findings agree with the studies of Dixit et al [8] and Prakash et al [15] who stated that the incidence of the posterolateral origin of the PFA from the FA was seen in 42.1% and 50% of the limbs, respectively. However, a lower incidence rate, 13.3%, 18.3%, 30.4% and 30.8%, were previously reported in the literature for this original pattern of PFA [11,16,17,20]. Moreover, in 25.6% of the cases in present study, the PFA originated from the posterior aspect of the FA with no side difference, but with a relative higher incidence in the female limbs.…”

“…The authors added that the knowledge of the original variations of PFA and its circumflex branches is of great significance in preventing the clinical complications that may occur in plastic and reconstructive surgery [8,16,17,25].…”

A Study on the Profunda Femoris Artery and Its Perforator Branches

“…The mean distance of PFA origin from the femoral artery in our study was 4.31 cms, which was similar to study by Siddharth P et al [3] who reported it to be 4.4 cms. MB Samarawickrama et al [10] observed distance of origin of PFA to be 5 cms and Mamatha et al [11] found it to be 3.9 cms. In the present study high origin of PFA was noted 2 cms from the mid inguinal point.…”
