We present a case of coronary dissection with retrograde extension to the sinus of Valsalva and ascending aorta after transradial percutaneous coronary intervention. Sealing the entry port of the coronary dissection with a stent resulted in failure. We made careful observation of the patient s course because the dissection did not seem to progress. Abnormal staining of the false lumen disappeared within an hour and the dissection repaired itself spontaneously in a day.

Two patients with cervical carotid artery aneurysms were treated with stent grafts. Case report #1 was a 65-year-old male with aneurysm of the right internal carotid artery and recurrent transient ischemic attacks. ⋯ Case report #2 also underwent coil embolization of the right external carotid artery to prevent retrograde filling of the aneurysmal sac. Endovascular stent graft obliteration of carotid aneurysms appears safe, feasible and a less invasive option compared to surgical repair.
