Polycythemia vera is a hematologic malignancy characterized by excessive proliferation of erythroid, myeloid and megakaryocytic elements within bone marrow, resulting in increased red cell mass, frequently leukocytosis and thrombocytosis. Patients with absolute erythrocytosis can be categorized into primary; those in whom excessive production of red cells results from a disorder intrinsic to the erythroid progenitor cells of bone marrow, or secondary; from excessive stimulation of an otherwise normal marrow by substance such as erythropoietin. Polycythemia vera is a disease process in which control prior to surgery decreases the frequency of perioperative complications. Surgery was postponed on an 61-year-old female patient found to have a hematocrit of 59%. She was phlebotomized and treated with hydroxyurea. Her hematocrit was decreased to 43%. General anesthesia was maintained with N2O-O2-enflurane after tracheal intubation. No thrombotic or bleeding problem was developed and she was discharged without complication at 14th day after operation.

The percutaneous transhepatic biliary drainage (PTBD) is an effective intervention as a palliative therapy for relieving a jaundice and cholangitis. It may be used in place of Endoscopic retrograde cholangiopancreatography (ERCP) in the obstructive biliary disease. Recently, by developing invasive procedures, the incidence of the complications such as bleeding and perforation has been increasing in the diagnosis and treatment of hepatobiliary disease. We report here on a case of remained drawstring after PTBD in a 85-year-old man. The patient was conducted PTBD for relieving a jaundice and cholangitis. And then the patient had complained of abdominal pain constantly. A few days later, we removed PTBD and attempted ERCP for removal of CBD stone. The ERCP showed remained drawstring around ampulla of vater and we removed it by IT knife. The drawstring was successfully removed.

Intracardiac thrombus during cardiopulmonary bypass (CPB) with full heparinization is very rare but fatal. A 60-year-old woman was scheduled for aortic and mitral valve repairs with a maze procedure for mixed aortic and mitral valvular heart disease with atrial fibrillation. Preoperative transthoracic echocardiography and cardiac computed tomography showed moderate aortic regurgitation and moderate mitral stenosis with regurgitation. There was no intracardiac thrombus. Aortic and mitral valve repairs with the maze procedure were successfully performed without unexpected events. During CPB weaning, a mobile hyper-echogenic mass in the left atrium was detected on transesophageal echocardiography. After cardiac arrest, it was surgically removed. On completion of the operation, weaning from CPB was accomplished uneventfully. The patient fully recovered and was discharged from the intensive care unit on her third postoperative day.

We report a case using cerebral oxygen saturation (rCbO2) for off-pump coronary artery bypass graft (OPCAB) surgery in a patient with co-existing Moyamoya disease. The rCbO2 with the routine monitoring for OPCAB surgery were monitored intraoperatively. In spite of infusing nimodipine (0.2 microgram/kg/min) and maintaining the end-tidal CO2 tension at 35-40 mmHg, a sudden reduction in the right-side rCbO2 from the base line value of 70-80%/78-83% (Left/Right) to 70-72%/65-70% was developed during the harvesting of the vascular graft. We increased the rate of phenylephrine infusion to increase systemic and cerebral perfusion pressure, and both rCbO2 values were elevated to 80%/70% within 3 minutes. However, the preferential reduction in the right-side rCbO2 compared with the left-side value was not corrected. While suspecting cerebral ischemia due to cerebral vascular spasm, we administered nimodipine 2 mg bolus and increased infusion rate to 0.5 microgram/kg/min. Finally, the preferential rCbO2 reduction in the right-side was corrected and both rCbO2 reached 84%/91%. We concluded rCbO2 monitoring is useful for detecting an intraoperative episode of cerebral ischemia and maintaining the optimal cerebral perfusion during OPCAB surgery with Moyamoya disease.

Anesthetic management for aortic arch aneurysm (AAA) surgery employing deep hypothermic circulatory arrest in a Jehovah's Witness (JW) patient is a challenge to anesthesiologist due to its complexity of procedures and their refusal of allogeneic transfusion. Even in the strict application of intraoperative acute normovolemic hemodilution (ANH) and intraopertive cell salvage (ICS) technique, prompt timing of re-administration of salvaged blood is essential for successful operation without allogeneic transfusion or ischemic complication of major organs. Cerebral oximetery (rSO2) monitoring using near infrared spectroscopy is a useful modality for detecting cerebral ischemia during the AAA surgery requiring direct interruption of cerebral flow. The present case showed that rSO2 can be used as a trigger facilitating to find a better timing for the re-administration of salvaged blood acquired during the AAA surgery for JW patient.

Transesophageal echocardiography (TEE) can provide real time information about anatomic and hemodynamic state and guide management in cardiac surgery.Despite greater technical advances, TEE has artifacts and pitfalls.This report describes a 68-year-old female patient underwent mitral valve replacement and Maze operation.After the procedures, TEE found right atrial mass which did not exist before cardiopulmonary bypass.After discussing with operator, right atrium was explored because it was thought to be a thrombus attached on pulmonary arterial catheter.However, it was revealed as folding of right atrium.The pitfalls of TEE resulted in misdiagnosis and unnecessary procedure.Therefore, authors reviewed echocardiographical artifacts and pitfalls in right atrium which could be misdiagnosed.

PURPOSE: To reassess the diagnostic value of plain radiographs, compared with computed tomography, in thediagnosis of acute traumatic spinal fracture. MATERIALS AND METHODS: Forty-six patients (total 64 cases) withacute traumatic spinal fracture were studied using plain radiographs and computed tomography. Fracture site andtype (according to the three-column theory), classification as major or minor injury, stability of fracture, andthe presence of associated soft tissue change were evaluated on plain radiographs and CT. The results of the twoimaging techniques were compared. RESULTS: Excluding eight cases of C1 and C2 fractures, 41 cases involvedfractures of the vertebral body, and 15 involved only the posterior column. Plain radiographs and CT showed,respectively, 27 and 25 cases of simple compression fracture, 13 and 16 of bursting fracture. One case ofcompression fracture was not detected on plain radiographs. The results of classification as major (43/56) orminor (13/56) injury were equivalent on plain and CT films. For the evalvation of unstable fracture, plainradiographs were superior to CT(stable fracture, 46/64; unstable fracture, 18/64), while for the evaluation ofsoft tissue change, CT was better than plain radiographs. CONCLUSION: If correct procedures are meticulouslyadhered to, plain radiographs of acute traumatic spinal injury provide good information for the diagnosis oftraumatic fracture.

BACKGROUND: The aim of this study was to compare the accuracy of measured cardiac output using the newly developed esophageal doppler device with that of the thermodilution method using a pulmonary artery catheter. METHODS: In 15 patients undergoing off-pump coronary artery bypass surgery, cardiac outputs were measured at four episodes of surgery; (1) after induction of anesthesia, (2) during dissection of the internal mammary artery, (3) during anastomosis of the left anterior descending artery, and (4) after closure of the pericardium. RESULTS: The bias between the two methods was 0.52 +/- 1.09 L/min. Analysis of the changes in cardiac output from sample episode 1 to 2, from sample episode 2 to 3 and from sample episode 3 to 4, expressed as percent change values, shows no significant differences between the two methods (P > 0.05). CONCLUSIONS: The esophageal doppler accurately reflects changes in cardiac output with time when compared with that of the thermodilution.
