Aortopulmonary fistula is an exceedingly rare vascular malformation. It is commonly derived after chest injuly or from complication of chest operation and aortic dissection and congenital aortopulmonary fistula is only several cases combined with Tetralogy of Fallot or aortic stenosis. But a congenital aortopulmonary fistula without any hemodynamic abnormalities was not reported. A 56-year old man with exertional dyspnea was admitted. In an examination on admission, there were no abnomalities. Aortography showed an aortopulmonary fistula that branches from the ascending aorta adjacent to the right coronary artery, running to the main pulmonary artery. Transcatheter coil embolization was performed and he was discharged 7 day after embolization without complication. Exertional dyspnea disappeared and careful follow up has be performed periodically.

PURPOSE: During the night time decision making on patients suspicious of appendicitis is often difficult because diagnosis and timing for operation are frequently delayed. Therefore, we analyzed above cases and solution is suggested. METHODS: This retrospective study included 360 patients who underwent laparotomies for suspected appendicitis at Hanil Hospital during one year, from March 1998 to Feb. 1999. They were divided into two groups according to presenting time to physician (Day time: 6 a.m. to 6 p.m., Night time: 6 p.m. to 6 a.m.). Sex & age distribution, time of presentation to physician, duration of symptoms, symptoms & physical findings, white blood cell counts, interval from presentation to operation, hospital stay, and pathologic diagnosis were compared. RESULTS: There were no significant differences in sex & age distribution, duration of symptoms, symptoms & physical findings, white blood cell counts, pathologic diagnosis between the two groups. However, during the night time, the interval from presentation to operation was longer than that of the day time (9.15 hours versus 4.83 hours, p<0.001), the rate of delayed appendectomy during the night was 58.0%, the rate of negative laparotomy increased when appendectomy was delayed for more than 12 hours compared with less than 12 hours (28.1% vs 11.7%, p<0.01), and in the cases with perforated appendicitis, delayed appendectomy for more than 12 hours had longer hospital stay compared with less than 12 hours (12 days vs 9.44 days, p<0.01). Factors causing delayed appendectomy were related to the physician (42.5%), lack of anesthetic & nursing supports (19.5%), failure to structure the operation team (20.7%), and patient itself (17.3%). When white blood cell counts were rechecked in the next morning, levels above 10,000 cells/mm3 were highly associated with appendicitis in contrast to that below 10,000 cells/mm3 (91.7% vs 43.5%, p<0.002).

Primary tumors of the heart are rare, three quarter of the tumors are benign, and nearly half of the benign heart tumors are myxomas. Cardiac myxoma usually originate in the left atrium about 75 percent, however, only 3 to 4 percent of myxoma are detected in the left ventricle. We report on a 32 years old woman with left ventricular myxoma who presented with shortness of breath, chest tightness, and general weakness. Acute pulmonary embolism and left ventricular myxoma were found on a perfusion lung scan and echocadiogram. A mass located on septal wall of left ventricle was excised en bloc. The patient recovered uneventfully and careful follow up has be performed periodically.

One of the complication during or after subclavian vein cannulation is intravascular catheter or wire embolization. Although some studies have reported safety of retaining foreign body embolization, and even death. The intravascular foreign body can be removed surgically or non-surgically. With improvement in instrument technology and technique, percutaneous retrieval of intravascular foreign bodies has become a relatively common procedure. Commonly used methods to remove intravascular foreign bodies are loop snare and basket technique. Sometimes biopy forcep can be used. We have experienced 2 cases of non-surgical removal of intravascular foreign bodies. One of the foreign bodies was 7cm wire fragment in right atrium(RA), the other was a 50cm guide wire. We used the standard loop snare technique for removal of 7cm wire fragment in RA and stone removal basket and 3.0mm ACS PTCA balloon to remove the 50cm short guide wire.

PURPOSE: It is not easy to determine the cause of pulmonary consolidative lesion. Even without any definite mass, malignancy cannot be ruled out. And sometimes, it is difficult to differentiate tuberculosis from pneumonia. To differentiate malignant consolidative lesion from benign one, we studied patterns of air bronchogram, mucoid impaction, and computed tomographic anglogram etc. MATERIALS AND METHODS: Fifty seven cases of pulmonary consolidative lesions(23 cases of malignancy,34 cases of benign lesion) were retrospectively reviewed by three radiologists. RESULTS: Among the 28 cases which showed a little air bronchogram(less than 1/3 of the whole lesion in volumetric measure with the eye) 19 cases were malignancy and nine cases were benign lesions. All of the 12 cases which showed profound air bronchogram over 2/3 of the whole lesion were benign lesions. Bronchiectasis was detected in 31 cases(four of malignancy and 27 of benign lesions). Among the 20 cases which didn't show the mucoid impaction five cases were malignancy and 15 cases were benign lesions. Out of eight cases with mucoid impaction filling the long segments(branching tree shape), seven cases were malignancy and one case was benign lesion. So called CT anglogram was detected in nine cases of malignancy and two cases of benign lesions. All of nine cases of malignancy showed CT anglogram which was like arborizing tree. CONCLUSION: Scanty air bronchogram, profound arborizing mucoid impaction and/or CT angoigram within consolidative lesion could suggest malignancy.
