The conundrum of endovascular common femoral artery treatment: a case report of lithoplasty as a viable solution

BACKGROUND: Highly calcific stenosis located in common femoral artery (CFA) represents a difficult target for endovascular treatment due to the possible need for stent implantation in that area. CASE SUMMARY: A 63-year-old man with history of coronary artery disease and previous multiple percutaneous transluminal angioplasties for peripheral artery disease (PAD) was admitted for recent onset left lower limb pain at rest with severe activity restriction (Leriche-Fontaine Class III and Rutherford Class III–IV). The angio-computed tomography scan showed a highly calcific stenosis of left CFA. The patient underwent lithoplasty balloon angioplasty followed by drug-eluting balloon inflation with excellent angiographic result and complete blood flow restoration. No procedural complications occurred. DISCUSSION: Highly calcified stenosis in PAD represents a huge challenge for endovascular treatment as not all lower extremity arteries are suitable for stenting because of compressive and torsional forces associated with stent fracture and restenosis. Lithoplasty is a new technology allowing effective blood flow restoration while minimizing vessel injury.
