The piriformis syndrome is a condition allegedly attributable to compression of the sciatic nerve by the piriformis muscle. Recently, magnetic resonance neurography and electrophysiologic study have helped to diagnose piriformis syndrome. High dose radiotherapy could induce acute and delayed muscle damage. We had experienced piriformis syndrome with fatty(More)
Sphincter of Oddi dysfunction (SOD) is a syndrome of chronic biliary pain or recurrent pancreatitis due to the functional obstruction of the pancreaticobiliary flow.

Atrial septal defect (ASD) is second common congenital heart disease that often leads to adult period. Intracardiac or transesophageal echocardiography (TEE) is essential for percutaneous closure of ASD using Amplatzer septal occluder. Dexmedetomidine (DEX), which is a highly selective α2-agonist, has sedative and analgesic properties without respiratory(More)
