A spontaneous dissecting Aneurysm of the posterior inferior cerebellar artery(PICA) is a very rare cause of subarachnoid hemorrhage(SAH) or ischemic stroke. We report a 53-year-old male patient with left PICA territory infarction due to the spontaneous dissection of the PICA. A Brain MRI revealed an infarction of the left PICA territory and an angiography showed spindle-shaped dilatations of the left PICA followed by an irregular luminal narrowing. An angiography taken 3 months later showed spontaneous resolution of the left PICA dissecting aneurysm. The management of the intracranial dissecting aneurysm is still controversial. Some authors recommend surgical approaches for the prevention of SAH while others present medical management. Our case showed spontaneous regression of the PICA dissecting aneurysm.

We present a retrospective analysis of arterial embolectomies performed at the Inje University Seoul Paik Hospital. During the period of March 1987 - Feburary 1996 twenty-six patients underwent embolectomies, eighteen patients were male and eight patients were female, mean age of patients was 56.8 years. Rest pain was the chief complaint in 24 patients, the remaining two patients complained of long term history of claudication after recovery of acute symtoms. But only 10 patients had sensory/motor symtoms. Heart was the most common source of embolization and frequent predisposing factor of embolism was ischemic heart disease in 8 cases and valvular heart disease in 11 cases. The sites of embolization were upper extremities artery in 6 cases, saddle embolism in 2 cases, lower extremities artery in 18 cases and the most common site of embolism was femoral artery in 11 cases. Preoperative angiography was taken in the diagnosis and planning of the embolectomy in 13 patients while in the other patient preoperative angiography was not taken. Only two cases were operated within the golden period of 6 hours and other cases were operated in more than 6 hours after embolization. In all patients, the Fogarty embolectomy catheter was used without bypass surgery via bachial ateriotomy in the embolism of upper extremities artery, bilateral groin approaches in the saddle embolism and transfemoral approach in the embolism of lower extremities artery. However 3 patients were re-operated via transpopliteal approach in the distal poplitiotibial embolism. Eighteen patients received perioperative anticoagulation therapy by heparin or fraxiparine and wafarin was used in 17 patients at the time of discharge and the indication of anticogulation was patients of valvular heat disease and/or atrial fibrillation, peripheral artery atherosclerosis and recurrent embolism. Postoperative results of the embolectomy were as follows: fouteen pateints had excellent results, five cases had symtom improvement after re-operation, B.K. amputation in 1 case who had sever atherosclerosis of lower extremities, recurrent embolism in 1 case and death in 2 cases the cause of death were acute renal failure and cerebral artery embolism, respectively. The complications of the embolectomy were reperfusion syndrome, pseudoaneurysm and intimal dissection in one case each. Conclusively the problems of embolism is delayed diagnosis and increasing number of old aged patient who had suffered ischemic heart diease. Preoperative angiography was not always needed for embolectomy. Selective anticoagulation therapy can decrease incidence of re-embolism. In the distal poplitiotibial embolism, seletive embolectomy of tibial artery was difficult.

We have experienced two cases of mycotic aneurysms of the superior mesenteric artery. The first case originated from septic embolism of infective endocarditis and the second case originated from salmonella enteritis eight months before. The aneurysms were diagnosed by abdominal ultrasonography and comfirmed by computed tomogram and angiography but the blood culture was negative in both cases at the time of the surgery. Both patient were successfully treated by resection only and the restorations of vascular continuity were not neccesary because of adequate collateral circulations to the intestine. Both patient's postoperative courses were uneventful after the follow up of one year and nine months, respectively.

Insulin resistance in patients with diabetes mellitus may be aggravated by various causes, including infection, obesity, and medications known to affect insulin sensitivity. During pregnancy, insulin resistance can be the result of hormones secreted by the placenta. Blood glucose control during pregnancy is important in preventing obstetric complications including miscarriage, congenital malformations, and macrosomia. We report a case of severe insulin resistance in an obese diabetic pregnant woman whose one-day insulin requirements were up to 1,000 IU.

PURPOSE: The incidence of subarterial ventricular septal defect(SA VSD) ranges 25-30% among oriental patients with VSDs, which is greater than 5% reported in western. Natural history of the disease is characterized by progressive aortic valve prolapse(AVP), frequently subarterial VSD, we evaluated clinical characteristics emphasizing on the incidence of AVP and the degree of AI as aging. METHODS: Study subjects consisted of 140 patients, who were diagnosed as subarterial VSD and operated in Seoul paik Hospital during a 5 year period from Jan.1988 to Dec. 1992. The data were analyzed detrospectively as to clinical profiles, data of cardiac catheterization, frequencies of AVP, and AI in 5 each age group, operative methods, postoperative complications and mortality. RESULTS: The incidence of subarteial VSD was 34.6% of total operated VSD cases. Data of preoperative cardiac catheterization showed mean values of Qp/Qs and systolic pulmonary artery pressure, 1.43+/-0.47 and 33.8x16.4mmHg in each. Aortic valve prolapses and aortic insufficiencies were observed in 70.0% and 20.7% among patients, which showed increasing tendencies as ages increased. As operative methods, patch closures through main pulmonary artery were done mainly. In mild cases without AI or with grade I AI, simple VSD closures were performed but in more a advanced cases, 10 aortic valvuloplasties and additional 2 aortic valve replacements were performed. Total mortality rate was 2.1%. CONCLUSIONS: In the management of subarterial VSD, early elective closure regardless of shunt volume is important to prevent progressive aortic valve prolapse leading to aortic insufficiency.

A very rare case of mycotic aneurysm in the descending thoracic aorta due to salmonellosis was treated in our hospital. The patient was a 62 year-old male who 48 days before the operation was admitted to the department of internal medicine complaining of fever, nausia, vomiting, and loose stool. He was treated for 35 days and discharged. Three days after discharge, however, the patient was readmitted to the hospital complaining of right upper quadrant abdominal pain. Fever developed on the third hospital day, and on the eighth hospital day, the patient complained of back pain and epigastric pain. A simple chest x-ray showed evidence of hemothorax in the left plueral space, and therefore, computed tomography of the chest was done. The patient was diagnosed as a ruptured mycotic aneurysm of the descending thoracic aorta, and was transferred to our Department of Thoracic and Cardiovascular Surgery. The aneurysm and infected tissues was widely debrided, and the site was then patched with a Dacron graft. Salmonella choleraesuis was identified in the blood and aneurysm cultures, and antibiotics were administered for 6 weeks according to the sensitivity of the organism. The patient experienced no complication thereafter and for the last three months since the operation, he has been leading a healthy and normal social life.
