Occipital alopecia after Open Heart Surgery under the Cardiopulmonary bypass is an uncommon minor complication. We had experienced Occipital alopecia in 6 cases after Open Heart Surgery. The cause of the alopecia was transient circulatory disturbance due to pressure effect of the patient`s head and intraoperative hypotension. The prodromal symptoms of the alopecia were erythema, itching, and watery discharge, but some patients showed non-specific symptoms. The common site of the alopecia was right occipital region and the size was 2-4 cm in diameter. The regrowth of the hair was completed at postoperative 3 to 5 months without specific treatment except conservative treatment. Fortunately the postoperative alopecia is a self-limiting condition, and spontaneous regrowth of hair is the rule without other complications.

Unroofed coronary sinus syndrome is an uncommon anomaly, Unroofed coronary sinus syndrome is caused by incomplete formation of the left atriovenous fold, and it usually is associated with Left SVC. If it is not diagnosed, a residual reversed or bidirectional shunt will result, and its complications will reduce life expectancy. We experienced 3 cases of unroofed coronary sinus syndrome which combines TOF with PLSVC, partial ECD, primum type ASD. In case of Unroofed coronary sinus syndrome which combines TIF with PLSVC, preoperative diagnosis was not made. In corrective operation for TOF of this case, pump weaning was failed due to hypoxia and cardiac arrest, and he expired at operation room. At autopsy of this case, complete unroofed coronary sinus was found. In the other 2 cases, partial unroofed coronary sinus syndrome was found in operation field and corrective operation was performed successfully. We report these 3 experiences with its review. ^u ++ Noninvasive Assessment of Pressure Gradients across Prosthetic Heart Valve by Doppler Ultrasound - A comparative study of the Duromedics Bileaflet Valves in mitral position and Normal Mitral Valves -with its review.

The aneurysm arising from the posterior cerebral artery is relatively uncommon, and has been reported in 0.7- 2.2% of whole cerebral aneurysm. Moreover, only a few cases of the giant aneurysm over 2.5cm in diameter arising from the distal portion of the posterior cerebral artery have been reported. Neurologic complications may occur after surgical treatment of this aneurysm due to difficult surgical approach and neurovascular complexity around the brain stem. Authors experienced a case of the thrombosed giant aneurysm with approximately 2.7cm in diameter arising from the P2 segment of the left posterior cerebral artery. Complete removal of the thrombus in the aneurysmal sac and direct neck clipping was performed via left subtemporal approach.

Penetrating injuries to the upper cervical spine resulting from gunshots are rare in South Korea due to restrictions of gun use. Moreover, gunshot wounds to the upper cervical spine without neurological deficits occur infrequently because of the anatomic location and surrounding essential structures. We present an uncommon case involving the surgical removal of a bullet located in the anterior arch of first cervical vertebra (C1) via a transoral approach without neurological complications or subsequent mechanical instability.

Extrarenal manifestations of hemolytic uremic syndrome (HUS) have increasingly been recognized and may be major determinants of mortality and morbidity. Although microthrombi are often found in the pulmonary and coronary circulation, apparent lung and cardiac involvement are clinically infrequent. We describe here a 10-month-old boy with HUS who developed pulmonary hemorrhage, acute respiratory distress syndrome and dilated cardiomyopathy. Complete renal as well as clinical recovery from these very uncommon complications was achieved by optimum supportive care.

Spontaneous pneumomediastinum is a very uncommon entity that is defined as the presence of free air in the mediastinum without an obvious etiology. The presence of air in the spinal canal, known as concurrent pneumorrhachis, is an extremely rare epiphenomenon of spontaneous pneumomediastinum. We report a rare case of spontaneous pneumomediastinum with pneumorrhachis associated with influenza. The patient was diagnosed without invasive procedures, was managed with supportive treatment, and recovered without any complications.

Venous aneurysms are uncommon in the lower limb and are more frequently found in the neck and thoracic and visceral veins. However, they have been reported to cause thrombosis, pulmonary thromboembolism, and other related complications. Popliteal venous aneurysms are often undetected because they are usually asymptomatic, but they may cause pulmonary thromboembolic events. We experienced a case of a 44-year-old man who was referred for recurrent pulmonary thromboembolism. He showed no other symptoms or signs except shortness of breath. A popliteal venous aneurysm was diagnosed incidentally because the examinations were performed to detect a deep vein thrombosis in relationship to the patient's history of pulmonary thromboembolism. We report a case of surgical treatment for a popliteal venous aneurysm that was complicated by pulmonary thromboembolism.

Mycotic anuerysms are uncommon but it is a fulminant infectious process frequently resulting in rupture and death if not properly treated. Commonly known it as infected aneurysm caused by noncardiogenic bacteremia. We experienced a case of infected aneurysm of the abdominal aorta that ruptured into the retroperitoneum. A 57 year old man was admitted with lower back pain, fever and palpable mass. It was identified as an inf cted abdominal aneurysm with staphylococcal septicemia. He underwent resection of aneurysm and replacement with a prosthetic graft and prolonged postoperative organism-specific antibiotics therapy. He recovered well and discharged without complications postoperatively.

Traumatic diaphragmatic rupture is quite uncommon and rarely lethal injury. However, delayed presentation between the injury and the diagnosis can cause a life-threatening condition with various complications such as intestinal hernia, obstruction, strangulation, respiratory distress. Here, we present a case of delayed presentation of traumatic diaphragmatic rupture in a 51-year-old man, and then discuss about the clinical implication of delayed presentation of diaphragmatic rupture with a review.

Isolated injury to the pancreas after abdominal trauma is uncommon, and a delay in diagnosis and treatment can increase the morbidity and mortality. Therapeutic decisions with respect to pancreatic trauma are usually made based on the site of injury and the status of the pancreatic ductal system. In this report, we describe the surgical management of pancreatic head transection as an isolated injury following blunt abdominal trauma. A 55-year-old man presented with epigastric pain that radiated to the back. Abdominal computed tomography revealed a hematoma in the pancreatic head and upstream dilatation of the main pancreatic duct. Endoscopic retrograde cholangiopancreatography showed complete disruption of and contrast leakage from the main pancreatic duct in the pancreatic head region with a nonenhanced upstream duct. Emergency pancreaticoduodenectomy was successfully performed, and the patient was discharged on postoperative day 9 without any complications.
