Drug-eluting stent patency at 6 months in the pedal artery of a patient with polyarteritis nodosa: a case report.

Drug-eluting stents are largely used in coronary arteries and more recently in tibial arteries owing to their potentially better outcomes compared with bare metal stents. A patient with polyartetitis nodosa and critical limb ischemia and a:dorsal foot ulcer was previously unsuccessfully treated with multiple angioplasties and subsequently underwent implantation of a drug-eluting stent in the pedal artery. At 6 months, stent patency on color Doppler ultrasound and complete healing of the foot ulcer were observed.
