Prоcedure: Right femоrаl аngiоgrаphy, percutaneous transluminal tibioperoneal angioplasty and stenting. Description of Procedure: The patient was premedicated and brought to the cardiovascular laboratory. The right inguinal region is prepped and draped in the usual sterile fashion. Local cutaneous anesthesia was obtained with 1% Lidocaine. A 6 French sheath was inserted antegrade into the right femoral artery. It was kinked and was replaced with a 6 French Arrow sheath.Findings: Selective injections into the right femoral artery revealed diffuse irregularities of the superficial femoral artery with a 95 percent mid to distal stenosis and a 60 percent distal stenosis. The distal popliteal artery had an eccentric 60 percent stenosis. The tibial peroneal trunk was diffusely diseased with sequential 95 percent stenosis present. The anterior tibial and posterior tibial arteries are both occluded. We gave intravenous heparin 2,500 units. The distal vessel was wired with a V18 wire. We then dilated both superficial femoral artery lesions with a 5 x 4 Diamond balloon and achieved good angiographic result. We then elected to approach the tibial peroneal trunk that was a high-grade stenosis leading into the only remaining circulation. This was dilated with a 3 x 4 Diamond balloon. This had satisfactory results, but we elected to stent this for a better long-term patency. We exchanged out the V18 wire for a coronary extra support wire and deployed a 3.5 x 40 mm GR2 coronary stent. This was then post-dilated to high pressures with a 3.5 x 40 mm NC Bandit balloon. We then performed inflations in the popliteal artery with a 4 x 2 Symmetry balloon, also achieving a satisfactory angiographic result. The balloon catheter was then withdrawn. The final angiographic result was excellent, with wide patency from the superficial femoral artery into the peroneal down to the ankle. Following the procedure, an ACT was obtained. The sheath was removed. A strong popliteal pulse was obtained. The patient was transported in stable condition to the recovery unit.Impression: 1. Successful percutaneous transluminal angioplasty of sequential 95 and 60 percent mid and distal superficial femoral artery lesions. 2. Successful percutaneous transluminal angioplasty of a 60 percent popliteal lesion. 3. Successful percutaneous transluminal angioplasty of diffuse 95 percent tibial peroneal trunk stenosis with stenting producing a residual stenosis to 0 percent.
