Abstract

This is a case report of a woman in her 60s with Rutherford class 3 bilateral calf claudication and a resting right Ankle Brachial Index (ABI) 0.49 and left ABI 0.57. The arteriogram of lower extremities demonstrates bilateral persistent sciatic arteries (PSAs). The patient had severe stenosis of left common iliac artery, and thus underwent successful stenting resulting in normalisation of flow and filling of PSA with symptom resolution.

Keywords: Interventional cardiology; Radiology (diagnostics).

Figure 1
Right persistent sciatic artery (PSA). The image demonstrates the right PSA originating from the internal iliac artery (IIA). The external iliac artery (EIA) divides into the superficial femoral artery (SFA) and the deep femoral artery (DFA). CFA, common femoral artery; CIA, common iliac artery.

Figure 2
Right popliteal artery occlusion. There is distal occlusion of the right persistent sciatic artery (PSA), and the right popliteal artery reconstitutes via collaterals from the right superficial femoral artery (SFA) and PSA.

Figure 3
Left common iliac artery stenosis. There is also a pseudo-occlusion or underfilling of the left internal iliac artery.

Left leg angiogram. The left common iliac artery (CIA) poststenting demonstrates contrast filling of the left internal iliac artery. EIA, external iliac artery.
Figure 5
Figure 5
Left persistent sciatic artery (PSA). The left leg angiogram post-CIA stenting demonstrates filling of the left PSA. EIA, external iliac artery; IIA, internal iliac artery.

Left leg angiogram. The left leg angiogram demonstrates continuation of the left persistent sciatic artery (PSA) as the popliteal artery.
