A patient had total occlusion of the left main coronary artery that was proved by coronary arteriography. Patients with total occlusion of the left main coronary artery have a varying clinical presentation and may have prolonged survival. In patients with good collaterals, left ventricular function may be preserved. This report reveiws the clinical and angiographic findings of a patient with occlusion of the left main coronary artery with symptoms of unstable angina pectoris but without congestive heart failure or EKG evidence of myocardial infarction.

We retrospectively evaluated the 20 patients who underwent the Raz operation for stress urinary incontinence. In the degree of severity, 4 cases were in Stamey grade I, 14 cases in Stamey grade II and 2 cases in Stamey grade III. Posterior urethrovesical angle(PUVA) and Urethral inclination angle(ULA) on lateral cystourethrogram were measured preoperatively and postoperatively. Preoperative PUTA and ULA were increased as the grade was higher, but postoperative PUVA and ULA were returned to normal range. The overall success rate were 90% and complications were minima1. We think that Raz technique for stress urinary incontinence is safe, reliable and low morbidity procedure.

Coarctation of aorta is a rare cause of secondary hypertension, and premature death will occur if no appropriate treatment is given. The only effective treatment was surgery before 1980, but restenosis was frequent. Several works on percutaneous transluminal angioplasty of the disease were reported. In patients with previously operated recoarctation, there is no doubt that balloon angioplasty is now the first choice of the therapy because of the surgical risks of reoperation. Nevertheless, there has still been some controversy regarding the application of this therapy to native coarctation, because of the potential risk of aortic disruption and the high incidence of restenosis. There have been some clinical reports of successful stent implantation for coarctation without major complications since 1991. We report on our experience with balloon-expandable stent implantation for native coarctation of the aorta in a 23-year-old man with congenital mitral stenosis. Aortogram showed a coarcted aortic segment of 3 mm in diameter and 25 mm long just distal to the left subclavian artery. The peak systolic pressure gradient across the coarctation before stent implantation was 100 mmHg. Stent implantation was performed with 14 X 40 mm balloon with Palmaz P308 stent. The peak systolic pressure gradient decreased to zero and the diameter of the coarctation of aorta increased to 14 mm after stent implantation immediately. The patient tolerated well and no significant complications were encountered during the procedure.

Beh et's syndrome is a multisystem disorder presenting with recurrent oral and genital ulcerations as well as ocular involvement. Vascular complications consist of venous thromboembolism, arterial aneurysms and occlusions, and they develop in about 25% of patients. Weakening of the aortic wall may lead to aneurysms that may rupture and cause life-threatening hemorrhage, but nothing in the surgical and nonsurgical techniques proposed for the treatment for aneurysms in Beh et's syndrome has proved to be satisfactory. The traditional treatment for thoracic aotic aneurysms is the surgical replacement of a prosthetic graft. Although advances in the operative care of patients with thoracic aortic aneurysms have been achieved, the associated morbidity and mortality are considerable, especially in those with coexisting conditions such as advanced age, coronary artery disease and heart failure. Currently, transluminally placed endovascular stent-grafts offer an alternative approach to treatment that is potentially less invasive with a lower risk. We report a 37-year-old male patient with thoracic aortic aneurysm associated with Beh et's syndrome. Transluminal endovascular stent-graft placement was attempted : the stent-graft was introduced through a 22-Fr sheath using a common femoral artery cut down and expanded to 25-30 mm in diamter. There was increased thrombosis of the aneurysm on a follow-up imaging study, and the patient was discharged without complications.

PURPOSE: In order to evaluate microstructural changes after shock wave exposure, gross, light microscopic and transmission electron microscopic findings were analyzed with rabbit gallgladders. MATERIALS AND METHODS: A preliminary study(2 rabbits) was performed to determine the dosage intensity of shock waves needed to inflict damage, using a EDAP LT 01 piezoelectric extracorporeal shock wave Iothotriptor. The gallbladders of three different groups of rabbits were given shock waves of various intensity. A storage value of 100, 50, 25 at rate of 20/sec under 80% power were given to group I (4 rabbits), group II( 4 rabbits), and group III(3 tabits), respectively. The rabbits were sacrified 6--12 hours later. RESULTS: The observed pathologic changes in the transmission electron microscopy were vaculization of cytoplasm and swelling of epithelial cells with dilatation and structural alteration of intracellular organelles, especially endoplasmic reticulum. Cell membrane rupture and necrosis were observed at the markedly affected area. The structural changes of intracellular organelles were minimally found at a storage value of 25. However, above pathologeic changes with dilatation and structural alterations of endoplasmic reticulums were more profund at value of 100. CONCLUSION: Early histologic changes induced by shock waves are dose dependent and the findings of cellular damage caused by ESWL might be explained as above.

The schwannoma is a benign neoplasm originating from Schwann cell. Solitary nerve sheath tumors such as benign schwannomas arising in the pelvic retroperitoneum are infrequently reported. Those tumors can indeed be misdiagnosed for other more common conditions both clinically and instrumentally. We report a very rare case of a benign retroperitoneal pelvic schwannoma of the obturator fossa, which was incidentally found and misdiagnosed as adnexal mass preoperatively in fifty one-years-old postmenopausal women.
