“…Duplication of the SFA is an extremely rare anatomical variant with only five reported cases in the imaging literature to the best of the authors' knowledge ( 2 – 6 ). Observation of duplicated the SFA has been described on a variety of diagnostic imaging modalities including digital subtraction angiography (DSA), CTA, color Doppler ultrasonography (CDU), and magnetic resonance angiography.…”

“…Duplication of SFA most commonly occurred in the proximal or mid segments of the SFA 4–8 cm below the common femoral artery (CFA) bifurcation. The duplicated SFA lumens were symmetric in caliber and were in the range of 4–7 mm in diameter ( 2 – 6 ). Distal convergence of the duplicated SFA typically occurred near the adductor hiatus, with the exception of one case by Akysoy et al.…”

“…No major arterial branches were observed from the duplicated SFA, although a small collateral artery branch was identified in one case arising from the duplicated medial limb ( 3 ). Two reported cases of duplicated SFA were incidentally discovered on DSA for planning of endovascular intervention for above knee popliteal artery stenosis and intraoperative DSA during embolectomy for acute limb ischemia ( 2 , 6 ). Incidental detection of the variant with CTA occurred while investigating a CFA pseudoaneurysm 2 months post coronary angiography ( 5 ).…”

An extremely rare case of duplicated superficial femoral artery (SFA) was incidentally observed on computed tomography angiogram (CTA) of the lower limbs for presurgical planning for an osteomyocutaneous fibula flap in a patient with T4a oropharyngeal squamous cell carcinoma (SCC). To our knowledge, this is the sixth reported case in the imaging literature. We performed a comprehensive review of the English literature and discuss the underlying embryological origin underpinning this rare anatomical variant.

“…Although US examination is an easily assessable and radiation-free modality for evaluation of lower extremity arterial disorder, there are some limitations to detect duplicated vessels when the operator is unaware of anatomic variation. For example, initial US examination of other two previous case reports [7] have not necessarily revealed the duplicated SFA. Since anatomic variations of femoral artery, including the duplicated SFA, are not common and may not be easily discovered by US examination only, CTA may provide a better implemental analysis of the vascular system and its surrounding tissues [5].…”

“…Variations of the femoral artery are rarely reported, especially for the superficial femoral artery (SFA) [1][2][3]. Few cases of the duplicated SFA have been reported with limited combinations of imaging modalities, such as computed tomography angiography (CTA), conventional angiography, ultrasonography (US), or magnetic resonance angiography (MRA) [2,[4][5][6][7]. We report a case of the duplicated SFA, which was diagnosed using both CTA and US, with a brief literature review.…”

Background: Duplication of the superficial femoral artery (SFA) is an extremely rare anatomic variation, with few case studies reported. We report one case of the duplicated SFA, discovered by both ultrasonography (US) and computed tomography angiography (CTA). We also reviewed literatures concerning 6 cases of the duplicated SFA (including our present case), and summarized the clinical and imaging features of the anatomic variation. Case presentation: A 55-year-old woman presented to our hospital with an intermittent cramp in the lateral aspect of the right leg. The patient underwent Doppler US examination on bilateral lower extremity arteries and veins to examine potential vascular abnormality. Incidentally, US discovered the duplicated left SFA and CTA of bilateral lower extremities revealed the anatomic orientation, course, length, diameter and distance of the duplicated left SFA. It was revealed to be divided into two trunks with similar luminal diameter and courses parallel. They reunited at distal thigh level. The findings of US and CTA examination did not correspond with the symptom of the patient, and the patient was discharged. Conclusion: We report a rare case of the duplicated SFA diagnosed with the combinations of US and CTA examination, which served as valuable imaging methods to detect and diagnose the vascular anatomic variation in lower extremities.

Arteries of the Lower Limb—Embryology, Variations, and Clinical Significance

Objectives: The purpose of this article is to review the embryology of the lower limb arterial anatomy along with common variants and their clinical relevance. Design: Embryologic variations of the lower limb arterial system may be explained by i.) persistence of primordial arterial segments, ii.) abnormal fusion, iii.) segmental hypoplasia/absence, or a combination of both. Persistent sciatic artery, corona mortis, and popliteal entrapment syndrome will also be discussed with associated symptoms, and potential complications. Conclusion: Knowledge of these variations is essential for surgical and endovascular management as failure to recognize them can result in complications.
