(A) Computed tomography angiography (CTA) showed the presence of complete persistent sciatic artery (PSA) with an incompletely developed superficial femoral artery (SFA) (type 2A PSA), without any aneurysmal change, and the complete obstruction of near-end popliteal artery by thrombus. (B) DSA revealed the obstruction of the remote of PSA and popliteal artery by thrombus. (C) One day of thrombolysis digital subtraction angiography (DSA) examination revealed partial dissolution of the thrombus in the blood vessels and multiple stenoses in the lumen, and advanced thrombosis was considered. (D) DSA revealed the vascular stent patency and no stenosis and thrombosis. (E) CTA revealed the patency of the whole PSA. There was no thrombosis or stenosis in the vascular stent. (F) CTA revealed that thrombosis in the vascular stent and the vessel was occluded.

The thrombus in the remote of PSA and near-end popliteal artery were also noted, and the distal arteries below the knee were not obstructed (Figure 1A). The patient underwent percutaneous arteriography and catheter-directed thrombolysis (CDT) of the PSA using infusion catheter (Merit Medical, Utah, USA) and urokinase (Figure 1B). Digital subtraction angiography (DSA) revealed partial thrombolysis, multiple stenoses, and an old residual thrombus in the lumen (Figure 1C). The thrombus was covered by implantation of a peripheral vascular stent (LifeStent, 5 x 170 mm, Bard, USA), the whole segment of the artery with the thrombus was covered (Figure 1D), and the distal end of the stent did not come into the popliteal artery at the knee joint. There was no thrombosis or stenosis in the vascular stent (Figure 1E). CTA showed that the right PSA distal was occluded from the pelvic level (Figure 1F).
