[Case of systemic arterio-pulmonary venous fistula detected during a routine group medical checkup].

A 55-year-old man was admitted following the discovery of a radiographic abnormality. A chest radiograph and computed tomography showed a subpleural nodule in the lingular division of the left lung with a dilated pulmonary vein. A pulmonary arteriograph showed no abnormal pulmonary artery in the pulmonary arterial phase, no abnormal pulmonary vein in the pulmonary venous phase, but an abnormal artery (left lateral thoracic artery) from the left subclavian artery with a fistula to the pulmonary vein.

[Evaluation of cerebral hemodynamics with perfusion CT].

We report on the evaluation of cerebral ischemic lesions with perfusion CT. Cerebral blood flow (CBF), cerebral blood volume (CBV) and mean transit time (MTT) of 52 patients mostly with ischemic cerebrovascular disease were analysed using the box-modulation transfer function method with 30 ml of contrast medium intravenously injected at 5 ml/sec. CBF, CBV and MTT of the middle cerebral artery (MCA) territory were 43.

The clinical utility of contrast-enhanced 3D MR angiography for cerebrovascular disease.

The purpose of this study was to evaluate the usefulness of contrast-enhanced 3D MR angiography (CE-MRA) with an automated bolus-detection algorithm (SmartPrep technique) and the specialized phased-array coils for the patients suspected cerebrovascular disease. Forty-three patients with brain attack were examined with CE-MRA. A tracker volume of SmartPrep technique was placed along the ascending aorta in the coronal image.

A case of subarachnoid hemorrhage presenting with temporary blindness disclosed by Xe CT-CBF study.

A 69-year-old male with right oculomotor palsy caused by non-ruptured right internal carotid-posterior communicating artery aneurysm suddenly became blind after cerebral angiography. He lost consensual response of left eye, in spite of no preretinal hemorrhage. Xenon computed tomography(Xe-CT) showed moderate cerebral blood flow(CBF) decrease of bilateral posterior cerebral artery territories at the values of 26.

Permissible arterial occlusion time in aneurysm surgery: postoperative hyperperfusion caused by temporary clipping.

The relationship between hyperperfusion and temporary clipping was evaluated to determine the safe limit for the duration of temporary clipping in aneurysm surgery. Twenty-one patients surgically treated for a ruptured aneurysm were examined using xenon-enhanced computed tomography on postoperative days 4 to 13. Eight of the 16 patients undergoing temporary clipping had focal hyperperfusion; whereas the five patients without temporary clipping had no hyperperfusion.

Effects of prostaglandin F2alpha and cisapride on small intestinal activity during the early postoperative period in humans.

The relationship between intestinal motor activity and the influence of prostaglandin F2alpha (PGF) and cisapride were investigated during the early postoperative period in 26 patients who underwent abdominal surgery. Records of intestinal motility were made using an infusion catheter. PGF, 0.

Patterns of intestinal motility recovery during the early stage following abdominal surgery: clinical and manometric study.

The purpose of this study was to evaluate the pattern of recovery of intestinal motility using manometric and clinical assessment in the postoperative ileus following abdominal surgery. We reviewed the charts of 18 patients who underwent partial colectomy for colon cancer (group A, without vagotomy) and compared them to those of 15 patients who underwent gastrectomy with truncal vagotomy and reconstruction by the Billroth I technique (group B, with vagotomy). A three-lumen catheter was inserted via the nose into the proximal jejunum for drainage of intestinal fluids and to record intestinal motility at laparotomy.

Carcinoma of the cystic duct protruding into the common bile duct: report of a case.

We report herein the case of 65-year-old man in whom a diagnosis of primary carcinoma of the cystic duct was made on the basis of Farrar's criteria. The patient was admitted with upper abdominal pain, and although there was no evidence of jaundice or a palpable mass, there was tenderness in his right upper quadrant. Carcinoma of the cystic duct was suspected on the basis of computed tomography and magnetic resonance imaging findings.

Cushing's syndrome caused by an ectopic pituitary adenoma of the sphenoid sinus: Adrenal crisis after partial resections of the adenoma.

A 60-year-old woman with an 8-year history of Cushing's syndrome was evaluated. Biochemical data were consistent with those of Cushing's disease. Plasma ACTH levels responded paradoxically to GnRH.

[Relationship of Helicobacter pylori to chronological transition of endoscopic atrophic pattern].

The prevalence of Helicobacter pylori (HP) were studied in 117 subjects with no gross findings whose stomach age was equal to its chronological age. HP was detected by culture. The prevalence of HP significantly was higher in thirties and forties than other ages, and in C3 and O1 groups than other groups.

[Insertion anomalies of the horizontal muscles and dysfunctions of the oblique muscles in the A-V patterns].

Insertion anomalies of the horizontal rectus muscles and dysfunctions of the oblique muscles were studied in 141 cases with A-V patterns of 824 patients with horizontal strabisums. The frequency of insertion anomaly among all cases of A-V pattern studied was 49.6%, there were more V pattern insertion anomalies than in those of A pattern, but the ratio of insertion anomalies in each type of A-V pattern was more in the A pattern than in the V pattern.
