RESUMO
Variant angina is a syndrome of cyclical chest pain at rest caused by vasospasm and associated with ST-segment elevation. Most of these cases are induced by the provocation with ergonovine or acetylcholine, and mechanical irritation of coronary artery by catheter, but spontaneous migrating spasm in right coronary artery is very rare. We report a fifty one year old male patient presenting as a variant angina due to spontaneous migrating spasm in right coronary artery during diagnostic coronary angiogram. The spasm was relieved spontaneously or by the administration of intracoronary nitroglycerin. No chest pain was documented after medication with calcium-channel blocker and nitrates on 6 month clinical follow-up. This paper presents our experience with a patient presenting with migrating coronay vasospasm of right coronary artery.

Transient cortical blindness is a known but rare complication occurring in 0.3~1% of patients undergoing cerebral or vertebral angiography. It is an extremely rare complication following cardiac catheterizaton and coronary arteriography. Cortical blindness is characterized by complete loss of visual perception and optokinetic nystagmus with preservation of ocular motility, pupillary responses, and normal fundoscopic examination. It has been suggested that its occurrence is due to an adverse reaction to the contrast agent, which causes an osmotic disruption of the blood-brain barrier. Patients outcome appears to be generally favorable with return of vision within 24-48 hr. We report a case of 48 year-old male patient with transient bilateral cortical blindness after coronary angiography.

Complete or partial agenesis of dorsal pancreas has been reported in a small number of pediatric and adult patients. A case of partial agenesis of dorsal pancreas was reported. This case was not associated with diabetes mellitus and pancreatic exocrine dysfunction, or abdominal pain. A 37-year-old man with chronic hepatitis B visited to our hospital due to further examination for chronic hepatitis B. Abdominal ultrasonography showed enlarged pancreatic head. Diagnosis was made by endoscopic retrograde cholangiopancreatography and computed tomography. Explor-laparotomy was not done.
