OBJECTIVE: The purpose of study was to assess the status of posterior communicating artery in patient with aneurysms arising from the internal carotid-posterior communicating artery and the angiographic blood flow pattern of anterior-posterior circulation through the posterior communicating artery especially to the posterior cerebral artery. The clinical outcomes according to the pattern of posterior communicating artery and the blood flow to the posterior cerebral artery were analysed. PATIENTS AND METHODS: The data includes 41 cases of internal carotid-posterior communicating artery aneurysm among 248 cases of aneurysms which were operated from September 1993 to August 1998. The clinical informations were obtained by review of the records and radiologic films retrospectively. The statistical analysis were performed using Chi-square tests. RESULTS: The female was predominant and peak age was fifties. The operative result was in close relation with initial Hunt-Hess grades(p=0.039), Fisher grade(p=0.001) but showed no statistical differences with age(p=0.106). The flow pattern of posterior cerebral artery was mainly from both anterior and posterior circulation(28cases, 68%), and the size of posterior communicating artery was smaller than P1 segment of posterior cerebral artery in 28cases(68%) but each of them showed no statistical differences with outcome. CONCLUSIONS: Even though there were no statistical differences of outcome according to the size of posterior communicating artery and the pattern of blood flow to the posterior cerebral artery, it is mandatory to save the posterior communicating artery for the preservation of otherwise normal blood flow to the perforators and main branches of posterior circulation.

Splenic abscess is an uncommon lesion and may be present either as a localized area of infection in the spleen or as a part of generalized sepsis. The diagnosis is difficult because of the rather nonspecific clinical picture. Hence, splenic abscess has a high mortality rate and is after diagnosed only at autopsy. Computerized tomography (CT) offers the clinician a reliable tool for the diagnosis of intra-abdominal abscess. A successful outcome is dependent on an early diagnosis and prompt treatment by splenectomy with antibiotic cover. We experienced a care of splenic abscess which was diagnosed by CT and treated by splenectomy with antibiotics. Postoperative course was relatively uneventful.

Leriche syndrome is a chronic disorder mostly in male and is a specific symptom complex due to thrombotic obliteration of the aortic bifurcation as result of an atherosclerotic change. The symptoms include 1) extreme liability to fatigue of both lower limbs; 2) symmetric atrophy of both lower limbs; 3) pallor of the legs and feets; 4) inability to maintain stable erection. There are several methods for surgical management of this disorder; 1) thromboendarterectomy with or without sympathectomy; 2) aortoiliac bypass graft; 3) aortofemoral bypass graft. Here we report a case of Leriche syndrome which was successfully managed with aortobifemoral bypass graft with Dacron and reviewed literatures on it briefly.

We report a case of thoracolumbar extradural arachnoid cyst in a 39-year-old male who presented with left lower thoracolumbar back pain, left buttock pain, hypesthesia in the left leg for three months. Magnetic resonance image revealed a cystic mass which lies posterior to the spinal cord from T12 to L2 vertebra level. The spinal cord was displaced anteriorly and flattened. We performed total laminectomy from lower half of T12 to upper half of L2 to remove cystic mass which was found to be an extradural lesion. There was a dural opening near the left L1 nerve root sleeve through which cerebrospinal fluid(CSF) was leaking and part of nerve roots were moving back and forth by CSF pulsation. A prompt improvement of the symptoms was noted after surgery. Possible mechanisms of spinal extradural arachnoid cyst and surgical intervention are discussed.

OBJECTIVES: To investigate the vestibular evoked myogenic potentials (VEMP) results in benign paroxysmal positional vertigo (BPPV) patients and to verify its clinical applications in BPPV. SUBJECTS AND METHODS: Forty-one patients with diagnosis of BPPV and 92 healthy volunteers who underwent VEMP testing. Patients were treated by canalith repositioning maneuvers according to the affected canal, and testing of VEMP was performed at diagnosis and after treatment. RESULTS: VEMP results of BPPV patients showed prolonged p13 and n23 latencies compared with those of the control group, and we could not find any significant difference in VEMP latencies between patients with posterior and horizontal canal type of BPPV. The number of times that the maneuver was repeated did not correlate with the degree of latency prolongation, but in the "no response" group, the number of times was considerably greater than those in the "response" group. CONCLUSIONS: We found that VEMP latencies are increased in BPPV patients, which may signify neuronal degenerative changes in the macula of the saccule. When an extensive neuronal damage was suspected by VEMP results such as "no response" in VEMP, the disease progress showed a chronic and resistive course. Therefore, we propose that VEMP could be a useful method to determine a clinical prognosis of patients with BPPV.
