From: The “Direct tip injection in occlusive lesions (DIOL)” fashion
Angiography and intravascular ultrasound (IVUS) of superficial femoral arterial occlusion treatment with the “DIOL” fashion in case 1. A Control angiography of right superficial femoral arterial occlusion. B After conventional bidirectional wiring failed, retrograde-DIOL with a forceful tip injection from the retrograde microcatheter revealed a tubular dissection with a vessel road (red arrow). C Reverse controlled antegrade and retrograde tracking and dissection (CART) and re-entry failed. Retrograde-DIOL was reperformed to expand the subintimal lumen (red arrow). DIOL contrast penetrated into the proximal lumen and the branch (orange arrow). D After two drug-eluting stents deployment, a satisfactory result was achieved
