Re-188 is useful candidate for therapeutic radionuclide because it has a physical half life of 17 hours, contains beta emissions suitable for therapy(maximum energy 2.12MeV) and emits a gamma ray that is suitable for quantitative diagnostic scanning(155keV). To use Re-188 as a radionuclide compound of angioplasty balloon radiotherapy, we investigated the labelling method and biodistribution of Re-188-DTPA We postulated that labeled Re-188-DTPA is preferable because it would be excreted via urinary system more easily than other compounds. To label Re-188 with DTPA, 1ml of 222MBq(6mCi) of Re-188 was added to DTPA solution(DTPA 20mg, $SnCl_2{\cdot}2H_2O$ 10mg, pH 3.5) and boiled at $100^{\circ}C$ for 120min in water bath. pH was adjusted to 5 with 2.3% sodium acetate. Labeling efficiency was measured using TLC-SG(acetone, saline). We evaluated biodistribution of Re-188-DTPA in sacrificed mice at 10 and 60 minutes after injection. We acquired images of kidneys, and drew time-activity curves in normal dogs and rats and calculated Tmax and Tl/2 in rats. The labelling efficiency was 95.7% on average. Labelling of Re-188-DTPA was.stable(90% after 5hours) in vitro at room temperature. According to time-activity curves of dogs and rats, it took 15 to 20 minutes after injection for Re-188-DTPA to be washed out through kidneys. In conclusion, Re-188-DTPA was successfully labeled, Re-188-DTPA was stable in vitro and was excreted early via kidneys in animals. We could recommend Re-188-DTPA as radionuclide of potential use in angioplasty balloon radiotherapy.

We report her on a rare case of a renal stent that migrated into the right ventricle in a patient with nutcracker syndrome. A 29-year-old woman was admitted to the hospital and she was suffering from flank pain. The computed tomography of the abdomen demonstrated that the left renal vein was compressed between the abdominal aorta and the superior mesenteric artery (nutcracker syndrome). A self expandable stent was placed across the left renal vein for treating her nutcracker syndrome. The next day after the procedure, the follow up chest radiograph showed that the displaced stent had migrated into the right ventricle. After percutanous endovascular stent removal had failed, the stent was ultimately removed by performing cardiac surgery. At the $6^{th}$ postoperative month, there have been no abdominal or cardiac symptoms.

A 67 years old male patient was admitted with back pain that had recurred from 6 months previously. Eleven years previously, he underwent stent grafting at the descending thoracic aorta for a chronic Stanford type B aortic dissection. The preoperative computed tomography showed aortic dissection from the origin of the left subclavian artery to the bifurcation of the abdominal aorta, and there was a type I endoleak at the proximal portion of the stent graft and aneurysmal dilatation of the descending aorta. A hybrid endovascular repair was successfully performed, and this involved debranching and rerouting the aortic arch vessels under extracorporeal cardiopulmonary bypass and then this was followed 13 days later by stenting in the ascending aorta, the aortic arch and the descending aorta. The postoperative computed tomography showed complete exclusion of the type I endoleak. After discharge, he has been followed up for 8 months without any problems.

This study was performed on 16 patients diagnosed with tsutsugamushi disease and cerebral infarction from January 2007 to December 2015. An acute cerebral infarction was diagnosed by brain MRI and MRA. Tsutsugamushi disease was diagnosed using a polymerase chain reaction. To distinguish the difference between the generalized cerebral infarction and infarction with tsutsugamushi disease, the blood pressure and body temperature were measured uponadmission. In general, the blood pressure increases during an acute cerebral infarction. Interestingly, in this study, 12 patients showed a systolic blood pressure less than 130 mmHg uponadmission. The location of the cerebral infarction and whether single or multiple cerebral infarction were examined. Thirteen patients had a cerebral infarction in anterior circulation and 3 patients developed in posterior circulation. To evaluate the coagulation disorders, prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimer, fibrinogen, fibrin degradation product (FDP). D-dimer, which is generally known to increase in an acute cerebral infarction, showed a significant increase in the 13 patients. Fibrin degradation products (FDP) showed a significant increase in 15 patients. The pathophysiological mechanism of tsutsugamushi disease is known as vasculitis, which may result in an endothelial cell injury and proliferation of the endothelial wall, which may lead to a cerebral infarction accompanied by coagulopathy. Without endothelial cell damage and proliferation, a vasospasm caused by vasculitis may cause vasoconstriction and cerebral infarction.

배경 및 목적: Stand A형 급성대동맥박리증의 박리 시발점이 수술치환부위 내에 있는 경우와 그렇지 않은 경우의 임상적 차이점을 분석하여 치료에 도움을 주고자 하였다. 방법: 1991년 3월부터 1999년 7월까지 본원에서 급성상행대동맥박리증으로 진단되어 상행대동맥치환술을 받은 40명의 환자를 대상으로 병력기록을 근거로 수술 소견 상 찢어진 부위를 발견한 환자 27명을 1군, 발견 못한 나머지 13명을 2군으로 나누고 환자의 술 전 상태와 수술소견 및 술후 경과의 임상적 차이점을 분석하였다. 결과: 1군에서 술전에 저혈압, 대동맥판막부전, 심허혈, 신부전 등이 더 많이 발생되었다. 수술 소견 상 대동맥근부 이상은 1군에서 많았다. 가성 내강 내 혈종은 2군에서 더 많이 관찰되었지만 통계적으로 유의하지는 않았다. 술후에 2군에서는 신부전이 더 많이 발생하였고 술후 출혈로 인한 재수술은 1군에서 더 많았다. 조기 수술사망은 1군에 6명으로 사망률은 22.2%이었고 2군에는 사망 례는 없었다. 결론: 본 연구를 통하여 상행대동맥에서 내막 파열이 발견된 1군에서는 2군에 비해 술전 상태가 불량하였고 대동맥판막 병변으로 수술이 복잡해져 사망률이 높다고 생각된다. 반면 원위부 하행대동맥에서 박리가 진행되어 상행대동맥으로 이어진 2군에서는 1군에 비해 순환 장애로 인해 술후에 신부전이 더 많이 발생되었다. 결론적으로 상행대동맥내막에 파열점이 없었던 군에서 수술 예후는 상행대동맥내막에 파열점이 있는 군보다 더 좋았다.

Thoracoscopic syrnpathicotomy is effective in treating not only palmar hyperhidrosis, but, also in treating axillary hyperhidrosis. In previous studies in Korea, sympathicotomy was focused on combinations including the End to 4th sympathetic chains (R2, 3, 4). Using a minimally invasive technique, the results of sympathicotomy of the 4th and 5th chains (R4, 5) of five patients, from February to August, 2002, for axillary hyperhidrosis without osmidrosis, were reviewed. All patients had a successful operation, their profuse sweating ceased. Three patients suffered from some degree of compensatory sweating. Among the three patients, only one patient suffered from moderate compensatory sweating over his back and thighs. Thoracoscopic R4, 5 sympathicotomy offers a very appealing method in the treatment for axillary hyperhidrosis in patients who have profuse axillary sweating.

Plummer-Vinson syndrome(Paterson-Kelly syndrome) is characterized by dysphagia due to upper esophageal or hypopharyngeal web, iron deficiency anemia, and atropic oral and glossal mucosa. This syndrome is usually known as precancerous lesion that develops into postcricoid carcinoma. Universally, the clinical manifestations of this syndrome were markedly improved after oral iron replacement therapy or endoscopic balloon or electrocautery treatment. 63 year-old woman was received a short segment, free jejunal transfer to be released from esophageal stricture. After the operation, the stenotic lesion proved to be Plummer-vinson syndrome with carcinoma in situ by pathologic study.

Abdominal tumors that can grow through vascular lumen and spread to the right heart are rare. Intravenous leiomyomatosis is a rare tumor that originates from the uterus and spreads through the vessels. Although histologically benign, tumor extension with mechanical obstruction of the inferior vena cava, right cardiac cavities, or even the pulmonary artery, may occasionally result in fatal outcome. The best treatment is complete surgical resection of the entire tumor using cardiopulmonary bypass and total circulation arrest, We report a case of intravenous leiomyomatosis of the uterus that showed intravascular growth up to the right atrium. The patient underwent successful resection of the tumor by one-stage cardiotomy with laparotomy.

Bow hunter's syndrome is a rare disease that shows the symptoms of vertebrobasilar insufficiency resulting from a dynamic obstruction or stenosis of the vertebral arteries during neck movement. This paper reports a case of a 59-year-old male who visited the emergency room with diplopia, tinnitus, and gait disturbance. Magnetic resonance imaging and angiography revealed a multiple cerebellar infarct, total obstruction of the right vertebral artery, and dynamic obstruction of the left vertebral artery during neck extension. As the infarction worsened, a thrombectomy was done. Posterior decompression and fusion at C5-6 were performed for the left vertebral artery. The left vertebral arterial patency was confirmed by intraoperative and postoperative angiography. No recurrence of the symptoms was observed for six months after surgery. Physicians need to pay attention to the diagnosis of vertebrobasilar insufficiency caused by an obstruction of the vertebral arteries during neck extension in cervical instability patients.
