Although dural arteriovenous malformations(DAVM) involving the occipital lobe can be the cause of variable posi-tive visual phenomena, the mechanism of these visual disturbances is not fully understood. We report a 42-year-old man with a left occipital DAVM presenting headache and positive visual phenomena in the right hemianopic field. Occipital DAVM was not accompanied by parenchymal lesions in a brain magnetic resonance imaging. The cerebral angiography demonstrated the retrograde flow into the dilated occipital cortical veins as well as the left occipital DAVM having multiple arterial feeders and the drainage into the left transverse sinus. All clinical symptoms disap-peared after a transarterial embolization. Brain 99mTc-ECD single photon emission computed tomography also showed the improvement of hypoperfusion on the left occipital area after the embolization. We believe that the venous hyper-tension by occipital DAVM impeding the perfusion to the occipital lobe plays an important role in producing positive visual phenomena on the hemianopic field.

Heterotopic pregnancy, simultaneous intrauterine and extrauterine pregnancy, is an extremely rare case. The incidence of heterotopic pregnancy was about 1 to 30,000 pregnancies, but it has increased after wider use of assisted reproductive technology. The rising incidence presents a serious problem as the diagnosis of this potentially fatal condition is often missed. Careful pelvic examination combined with serial beta-hCG determinations, and transvaginal sonography to evaluate the adnexal region are necessary prerequisites for early diagnosis. We report a case of heterotopic pregnancy following in vitro fertilization and embryo transfer(IVF-ET) with a brief review of literature.

A temporary balloon occlusion of internal carotid artery (ICA) was performed in 3 patients for carotid artery endarterectomy and 1 patient require sacrifice ICA with neck malignancy. EEG monitoring and neurologic evaluation was done during the test. In one patient who has bilateral ICA stenosis more than 95% shows slurred speech and aphasia during test. Another 3 patients shows no clinical change during test, and operation was done without shunt. There were no postoperative neurologic complication. We believe that preoperative balloon occlusion of ICA provide another helpful criteria to decide using shunt. But it needs another hemodynamic analysis tool according to other's report.

Local or general anesthesia is essential for safe operation. Patients in good preoperative condition are relatively to tolerable to the operation, but the patients in poor preoperative condition have the high mortality and morbidity during and after the operation. Therefore, we should choose the anesthetic agents and methods, which cause little effect to the patient's life. Among the intraventricular blocks, bundle branch is the most common type, and left bundle branch block may progress to a more serious condition of complete heart block. Optimal anesthetic management of patients with cardiovascular disease requires a thorough knowledge of normal cardiac physiology, the circulatory effects of the various anesthetic agents, and the pathophysiology and treatment of these diseases. The authors successfully performed balanced anesthesia in operation of a 63 year old female patient who showed complete left bundle branch block pattern in a preoperative electrocardiographic tracing without any subjective symptoms.
