Successful Endovascular Therapy Using the Transtibial Approach in a Patient With a History of Iliofemoral and Femorofemoral Surgical Bypass.

Multiple stenotic lesions may restrict the access sites for endovascular therapy in the lower extremity arteries. Because guide sheaths used for endovascular therapy have recently become easier to insert, they are directly inserted into the posterior tibial or dorsalis pedis artery to perform the transtibial approach. We herein describe an 81-year-old man who was admitted to our hospital because of claudication of the left lower extremity. He had a history of left iliofemoral and femorofemoral bypass surgery. The patient's symptom was due to a stenotic lesion extending from the left common femoral artery to the distal part of the left superficial femoral artery. In an angiographic procedure using the antegrade approach via the right radial artery, a multipurpose catheter became stuck in the middle of the left iliofemoral bypass. The antegrade ipsilateral approach was too close to the stenotic lesion for the insertion of the guide sheath. Therefore, a retrograde approach using a 5-French guide sheath inserted via the dorsalis pedis artery was successfully performed.
