Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare, and has been reported previously in pregnant patients in association with collagen vascular disease, and in cases of high-energy trauma or intensive activity in athletes. There is no consensus yet on indications for medical or surgical therapeutic modality. Due to the rarity of spontaneous dissection of external iliac artery, its natural history has been poorly described.

A healthy 50-year-old male with normotension was admitted with an acute onset of left flank pain. Left external iliac artery dissection was diagnosed by abdominal computed tomography.

Stent dislodgement is a rare complication of complex percutaneous coronary artery intervention and is often associated with significant morbidity. We report a case of stent dislodgement complicated by coronary artery dissection and acute total occlusion of left circumflex coronary artery. Direct expansion of the dislodged stent was performed using parallel wire technique and small balloon. An overlapping stent was implanted for remained coronary artery dissection. Coronary artery flow was restored and ST segment elevation was normalized after successful intervention.
