Primary intimal sarcoma of the pulmonary artery is a rare disease and there has been no report of any case originating from the pulmonary valve. Recently we experienced a 62 year-old female patient who had a primary intimal sarcoma of the pulmonary valve with distal metastasis. She was brought to medical attention due to exertional dyspnea facial edema productive coughing and general weakness for 1 month. Chest CT and echocardi-ography suggest an acute pulmonary thromboembolism or tumor. Exploration showed a large polypoid mass arising from the pulmonary leaflets and multiple masses on distal pulmonary arteries. We replaced the pulmonary valve and reconstructed the pulmonary artery. She received radiotherapy 1 month postoperatively and now 4 months after surgery she has begun receiving chemotherapy.

PURPOSE: To determine the usefulness of microbubble contrast enhanced power Doppler ultrasonography (PDUS)for the detection of residual tumor in hepatocellular carcinomas (HCCs) treated by transcatheter arterialchemoembolization (TACE). MATERIALS AND METHODS: Fourteen nodular HCCs (size range: 1 - 7.3 cm, mean: 3.5) intwelve patients treated by TACE, and on the basis of follow-up liver CT, thought to have a residual tumor, wereincluded in this study. Between July 1997 and April 1998, PDUS examinations were performed with a 2-4 MHz convextransducer before and after intravenous injection of a microbubble contrast agent (Levovist(, Schering AG, Berlin,Germany). Real-time power Doppler ultrasonographic images were recorded on videotape and representative imageswere color-printed. Tumor vascularity was analyzed on real-time images with regard to its presence or absence, andchanges, and two observers reached a consensus. The results were compared with those of other diagnostic tests(three-phase helical CT, conventional angiography, percutaneous biopsy, and/or surgical pathology). RESULTS: Contrast-enhanced PDUS revealed intratumoral vascularity in ten of 14 tumors, none of which showed vascularity onunenhanced PDUS. In the remaining four tumors, both unenhanced and enhanced PDUS showed intratumoral tumorvascularity, which in all cases was more pronounced on enhanced than on unenhanced PDUS. Other diagnostic testsrevealed residual tumors in eleven lesions. CONCLUSION: Microbubble contrast-enhanced PDUS was more sensitivethan non-enhanced PDUS in depicting vascularity within a residual tumor and could be a useful method for thedetection of residual tumor in HCCs treated by TACE.

PURPOSE: To assess the effectiveness of subsegmental transcatheter arterial chemoembolization(TAE) forhepatocellular carcinomas(HCCs) on the basis of tumor necrosis rate. MATERIAL AND METHODS: Between May 1996 andMarch 1998, ten patients with single HCC after subsegmental TAE underwent surgical resection. Subsegmental TAE wasperformed by injecting a mixture of lipiodol and adriamycin followed by gelatin sponge particles into the distalbranches of the subsegmental arteries. Tumor size and the extent of necrosis were analyzed in ten resectedlesions, and in all patients, complications after subsegmental TAE were assessed. RESULTS: The size of resectedtumors ranged from 1 to 5,5cm. On histological examination, complete necrosis was seen in 6 to 10 resected lesionsand 95% necrosis in three. In the remaining lesion, 85% necrosis had occured. Complete necrosis was noted in 4 of6 small HCCs(less than 3cm in diameter), while in the remaining two the extent of necrosis was 95%. Nocomplications were observed. CONCLUSION: For the treatment of HCC, subsegmental TAE is safe and effective.Curative therapy must, however, involve follow-up and repeated TAE.

Multiple gastric caner, now considered to be a sort of multiple primary cancer by Moertel's classification, is a special type of cancer in which two or more tumor lesions arise independently from the stomach. Although its incidence is rare and it has never been reported in Korea yet, the report of multiple gastric cancer is increasing with lengthened life survival and improved diagnostic method. We recently experienced two cases of triple gastric cancer, the one in 53-years-old male who had well differentiated adenocarcinoma(EGC IIb+c) on antrum, poorly differentiated adenocarcinoma on cardia and moderately differentiated adenocarcinoma on mid-body, and the other in 65-years-old female who had two poorly differentiated adenocarcinoma on cardia and anterior wall of low body and moderately differentiated adenocarcinoma (EGCIIc) on posterior wall of low body. Triple gastric cancer is rare, so we reported 2 cases of triple gastric cancer.

Background: Although traumatic thoracic aortic rupture is potentially a fatal condition requiring surgical attention, the presence of concomitant injury involving other parts of the body may greatly increase the risk of cardiopulmonary bypass. We report our experience of treating associated injuries prior to the thoracic aortic rupture in these patients. Material and Method: From 1997 to 2003, the medical records of 24 traumatic aortic rupture patients were retrospectively reviewed and checked for the presence of associated injury, surgical method, postoperative course, and complications. Surgical technique comprised thoracotomy with proximal anastomosis under deep hypothermic circulatory arrest followed by side arm perfusion to reestablish cerebral circulation. CSF drainage was performed to prevent lower extremity paraplegia. Result: Major concomitant injuries (n=83) were noted in all of the reviewed patients. Of these, there were 49 thoracic injuries, 18 musculoskeletal injuries, and 13 abdominal injuries. Operations for associated injuries (n=16) were performed in 12 patients on mean 7.6+/-12.6 days following the injury. The diagnosis of aortic rupture at the time of injury was detected in only 18 patients. Delayed surgery of the thoracic aorta was performed on average 695+/-1350 days after injury and there were no deaths or progression of rupture in any of these patients during the observation period There were no operative deaths and no major postoperative complications. Conclusion: Treating concomitant major injuries prior to the aortic injury in traumatic aortic rupture may reduce surgical mortality and morbidity.
