Arytenoid subluxation or recurrent laryngeal nerve paralysis may result from injury to the larynx following endotracheal intubation or blunt laryngeal trauma. Early diagnosis is important for appropriate treatment and better prognosis. A 62-years-old man was admitted for cholecystectomy. He was intubated without any difficulty and nasogastric tube was inserted with the help of laryngoscope and Magill forcep before surgery. He had a weak voice and hoarseness after atraumatic extubation and those symptoms did not improve even 2 days after. Indirect laryngoscopy, videolaryngotelescopy, electromyography(EMG) and computed tomographic findings revealed anterior, inferior subluxation of left cricoarytenoid cartilage associated with left thyroarytenoid muscle denervation and resultant unilateral vocal cord palsy. Conservative treatment for 40 days after the operation and follow-up examination was done. The voice quality was improved and indirect laryngoscopy examination showed that right vocal cord crossed midline in a attempt to meet its paralyzed counterpart on phonation.

From January, 1984 to January, 1985 twelve patients with unstable fracture and fracture-dislocation of the thoraco . lumbar spine with neurologic deficits were treated with Harrington Instrument. Fixation by Harrington Instrumentation appeared to provide stabilization, reduction and return of neural function. Author performed Harrington Instrumentation with experience of 12 cases of unstable thoraco . lumbar spine fructure and fracture-dislocation with neurologic deficits. Results were as follows : 1) Spinal fracture and fracture-dislocation were most common in thoraco . lumbar Junction. 2) Harrington Instrumentation was very effective for keeping the spine stability in unstable fracture. 3) Six cases (50%) had a complete neurologic deficit and six cases (50%) had a incomplete neurologic deficit, two cases of the six patients with complete neurologic deficits recovered slightly but two cases with incomplete neurological deficit gained complete recovery. 4) During the postoperative period, early ambulation was possible and average admission period were 71 days. 5) Correction of spinal deformity. A. Average value of kyphotic angle (12.5 degrees). B. Average value of Iw(Index of weding) (1.32). C. Displacement was completely corrected in eight patients (100%).

At the Kyung Hee Medical Center all patients receiving general anesthesia in the operating room are monitored continuously with electrocardioscope, Burdick CS-515 Monitor, and recorded by EK4S ECG. Among 50 patients 18 cases (36%) developed a variety of arrhythmias. Seven (14%) were considered serious in nature, such as ventricular extrasystoles. There was an increased incidence of arrhythmias during induction of anesthesia, in old age group and in poor risk patients. Continuous cardiac monitoring is valuable, easy, and practical in virtually all instances during anesthesia and surgery.

The effect of a new analeptic, doxapram hydrochloride, on respiration has been studied in ten subjects anesthetized with thiopental or with nitrous oxide-oxygen-halothane. The results are as follows: 1) Respiratory stimulation was more pronounced in the group anesthetized with thiopental than that with nitrous oxide-oxygen-halothane. 2) The stimulatory effect lasted for four minutes. Subjects who received multiple doses of the drug, however, showed a cumulative effect. 3) Most cases showed moderate hypertensive effect and brief electrocardiographic change was observed in one of the ten.

In an attempt to clarify the protective action of an antioxidant agent against acute toxicity of thioacetamide (TAA) and in order to throw some light on an satisfying concept of the mechanism of its action, a single dose of alphatocopherol (200 mg per kg) was given orally by stomch tube to male mice prior to the administration of thioacetamide in a dose of 200 mg per kg of body weight. Sections of liver samples, obtained from the mice which were sacrificed at intervals of 3, 6, 9, or 12 hours after TAA administration, were stained using the methyl green-pyronin technique. At 3 hours following TAA administration, the pretreatment with alpha-tocopherol inhibited almost completely such alterations of the hepatocytes in the animals given TAA alone, as revealed by loss and clumping of cytoplasmic pyroninophilic granules in the periportal zone of the lobule. At 6, 9, and l2 hours, the prevention of alpha-tocopherol was incomplete in degree and extent. The changes of the hepatocytes were more intense and extensive in the TAA-treated 6 to 12 hour-groups than in the 3 hour-group of TAA-treated ones. Some discussion is given of the mechanism of TAA toxicity, with respect to the microsoma1 lipid peroxidation.

PURPOSE: To describe the imaging findings of traumatic intracranial aneurysms (TICA) in children. MATERIALS AND METHODS: Five boys aged 3-15 (mean, 7) years with surgically confirmed TICA were included in this study. All had a history of nonpenetrating head trauma, and they underwent precontrast CT imaging immediately after the injury and follow-up CT or MRI. In all cases, angiography revealed the presence of aneurysms, which at surgery were shown to be pseudoaneurysms with severe adhesions. RESULTS: Angiography demonstrated that all aneurysms were located in the anterior cerebral artery (ACA) or its branches. The precise locations were the A2 segment of the ACA, the site of origin of the callosomarginal artery or its first branch, or of the anterior internal frontal artery, or between the first and second branch of the pericallosal artery. In all patients, precontrast CT performed immediately after trauma depicted subarachnoid hemorrhage (SAH) in the anterior interhemispheric fissure (AIHF). Follow-up precontrast CT showed nodular high density around the anterior falx in three, recurrent SAH in the AIHF in two, and intracerebral hemorrhage (ICH) with intraventricular hemorrhage in two. In two patients with a nodular high-density lesion, nodular enhancement was demonstrated at postcontrast CT, and in one, follow-up MRI revealed a nodular signal void around the anterior falx; nodular enhancement was seen at postcontrast imaging, and MR angiogram depicted a saccular aneurysm. In one patient, MRI demonstrated infarction in the caudate nucleus and ACA territory. CONCLUSION: If, after head injury, an area of nodular high density is revealed by CT, or a signal void by MRI, or if SAH or ICH is present around the anterior falx, the possibility of TICA should be considered.

PURPOSE: To assess the results and usefulness of interventional procedures for hepatic arterial stenosis or thrombosis following liver transplantation. MATERIALS AND METHODS: During the past five years, eight patients aged 1-59 (mean, 39) years among 187 liver transplant recipients showed elevated of liver enzyme levels (AST/ALT) and decreased arterial flow at Doppler ultrasound. Hepatic arteriography revealed luminal stenosis or occlusion at the proper hepatic artery, and six patients, one of whom required thrombolysis before the procedure, underwent percutaneous transluminal angioplasty (PTA) using a balloon. In two with thronbosis, thrombolysis without PTA was performed. In order to increase hepatic arterial flow, four patients underwent additional coil embolization of the gastroduodenal or splenic artery. RESULTS: Hepatic arterial flow recovered in all six patients after PTA. Three required repeat PTA for restenosis and one of these needed stent placement after repeated PTA. At follow-up, 6-17 months later, the three had good hepatic function. Within four days, the other three expired due to graft failure, hepatorenal syndrome and sepsis. One of the patients who underwent thrombolysis without PTA expired and the other required retransplantation. In this case there were no procedure - related complications. CONCLUSION: Radiologic interventions are useful for treatment of hepatic arterial stensis or thrombosis in patients with liver transplantations.

BACKGROUND: Intracoronary stenting in large coronary artery with diameters >3 mm has been shown to be beneficial in the treatment of acute or threatened closures complicating balloon angioplasty and in the prevention of restenosis. However, whether equally favorable results are afforded by stent placement in small vessels (<3 mm) remains unclear. Accordingly, we evaluated the safety and feasibility of intracoronary stenting in native coronary vessels less than 2.75 mm in size. METHODS: Between January 1997 and July 1998, seventy eight patients with 81 lesions were treated with 83 stents, regardless of clinical setting. The angiographic criteria for enrollment included at least 70% stenosis and a vessel that reference diameter was less than 2.75 mm. Every patients received aspirin (300 mg qd, indefinitely) and ticlopidine (250 mg bid, one month) and was given a bolus dose of 10,000 U heparin during procedure. RESULTS: Angiographic success was achieved in 80 of 81 attempts (98%). There was one in-hospital death because of pump failure in AMI patient. There was no acute stent thrombosis. At 6 month follow-up, event free survival was achieved in 90% of patients and angiographic restenosis was found in 28% of patients (9/32). CONCLUSION: The present observational study demonstrates that angiography-guided stent placement in coronary artery < 2.75 mm in diameter is safe and effective in conjunction with current stent deplyment technique and antiplatelet protocol.

A case changing blood pressure severely by manipulation of the huge tumor mass during the brain tumor surgery was observed. Decreased blood pressure (55/35 mmHg) might be caused by the stimulation of the brain increased to 150/75 mmHg after a neurosurgeon undermined and elevated the tomor mass, and blood pressure decreased again to 55/35 mmHg when he put it on the same position. Removing the mass completely, blood pressure was stabilized (about 130/70 mmHg). There are central vasomotor centers of autonomic nervous organization in the hypothalamus, midbrain, pons or medulla oblongata of the brain. By the stimulation of specific region in the above area, various features of responses were anatomically defined. The supratentorial contents may herniate through the tentorial incisura into the infratentorial spaces and posterior fossa, when intracranial pressure gradients become large enough to overcome the resistance of the brain tissue, and they can affect vital changes.
