AIM: To conduct a single-stage, combined computed tomography (CT) arterial portography (CTAP) and CT arteriography (CTA) imaging operation, we used Y-shaped sheaths with 2 valves, which allowed the insertion of 2 catheters simultaneously. METHODS: Of 1254 patients who underwent abdominal angiography for transarterial embolization and/or intraarterial chemotherapy in our department from May 2002 to November 2009, 664 patients in whom Y-shaped sheaths with 2 valves were used underwent CT angiography using a combination of CTA and CTAP. The Seldinger method was used to insert a 10 cm Y-shaped short sheath with 2 valves into the femoral artery. Under radiographic guidance, a 3.2 French (Fr) catheter was placed in the celiac artery or proper hepatic artery, and a second 3.2 Fr catheter was then placed distal to the inferior pancreaticoduodenal artery of the superior mesenteric artery. CTAP was then performed followed by CTA 10 min later. Photographs were taken during the early and late phases of the ***: Insertion of 3.2 Fr catheters was not possible in 6 of 664 (0.9%) patients with strong curvature of the femoral artery and 4 of 664 (0.6%) patients with strong curvature of the abdominal aorta. In addition, performing CTAP and CTA as a single-stage combined intervention was not possible in 14 of 664 (2.1%) patients whose right hepatic artery originated from the superior mesenteric artery and in 8 of 664 (1.2%) patients whose left hepatic artery branched from the left gastric artery. There were no sheath-related complications such as those related to arterial dissection or hemostasis. CONCLUSION: Although transfers to and from the CT room were necessary for anatomically variant patients, CT angiography using the Y-shaped sheath for combined CTAP and CTA was considered useful.

Successful treatment of multiple lung metastases of hepatocellular carcinoma by combined chemotherapy with docetaxel, cisplatin and tegafur/uracil

第六次全国大肠癌会议暨中日韩大肠癌会议

The presence of metatatic tumor in regional lymph nodes at the time of colorectal surgery is of major significance for tumor recurrence and prognosis in patients with colorectal cancer. However, conventional staining may not be sensitive enough. Mutant allele-specific amplification(MASA) is a method to be able to detect micrometastasis to lymph nodes that are histologically diagnosed as negative.

We report the successful treatment of multiple lung metastases after hepatic resection for hepatocellular carcinoma (HCC) with combined docetaxel, cisplatin (CDDP), and enteric-coated tegafur/uracil (UFT-E). A 68-year-old man was diagnosed with multiple lung metastases of HCC 7 mo after partial hepatectomy for HCC. Oral UFT-E was given daily and docetaxel and CDDP were given intra-arterially (administered just before the bronchial arteries) every 2 wk via a subcutaneous injection port. One month after starting chemotherapy, levels of tumor marker, protein induced by vitamin K absence(PIVKA--), decreased rapidly,and after a further month, chest X-ray and computed tomography revealed the complete disappearance of multiple liver metastases. Two years after the combined chemotherapy, HCC recurred in the liver and was treated but no pulmonary recurrence occurred. In the absence of a standardized highly effective therapy, this combined chemotherapy with docetaxel, CDDP and UFT-E may be an attractive option for multiple lung metastases of HCC.

AIM: To evaluate sample adequacy, safety, and needle passes of a new biopsy needle device compared to the Quick-Core biopsy needle for transjugular liver biopsy in patients affected by liver disease. METHODS: Thirty consecutive liver-disease patients who had major coagulation abnormalities and/or relevant ascites underwent transjugular liver biopsy using either a new needle device (18 patients) or the Quick-Core biopsy needle (12 patients). The length of the specimens was measured before fixation. A pathologist reviewed the histological slides for sample adequacy and pathologic diagnoses. The two methods’ specimen adequacy and complication rates were assessed. RESULTS: Liver biopsies were technically successful in all 30 (100%) patients, with diagnostic histological core specimens obtained in 30 of 30 (100%) patients, for an overall success rate of 100%. With the new device, 18 specimens were obtained, with an average of 1.1 passes per patient. Using the Quick-Core biopsy needle, 12 specimens were obtained, with an average of 1.8 passes per patient. Specimen length was significantly longer with the new needle device than with the Quick- Core biopsy needle (P < 0.05). The biopsy tissue was not fragmented in any of the specimens with the new aspiration needle device, but tissue was fragmented in 3 of 12 (25.0%) specimens obtained using the Quick-Core biopsy needle. Complications included cardiac arrhythmia in 3 (10.0%) patients, and transient abdominal pain in 4 (13.3%) patients. There were no cases of subcapsular hematoma, hemoperitoneum, or sepsis, and there was no death secondary to the procedure. In particular, no early or delayed major procedure-related complications were observed in any ***: Transjugular liver biopsy is a safe and effective procedure, and there was significant difference in the adequacy of the specimens obtained using the new needle device compared to the Quick- Core biopsy needle. Using the new biopsy needle device, the specimens

AIM： To evaluate the efficacy of CT-maximum intensity projection （CT-MIP） in the detection of gastric varices and their infiowing and outflowing vessels in patients with gastric varices scheduled to undergo balloonoccluded retrograde transvenous obliteration （B-RTO）. METHODS： Sixteen patients with endoscopically confirmed gastric varices were included in this study. All patients were evaluated with CT-MIP using threedimensional reconstructions, before and after B-RTO. RESULTS： CT-MIP clearly depicted gastric varices in 16 patients （100%）, the left gastric vein in 6 （32.5%）, the posterior gastric vein in 12 （75.0%）, the short gastric veins in 13 （81.3%）, gastrorenal shunts in 16 （100%）, the hemiazygos vein （HAZV） in 4 （25.0%）, the pericardiophrenic vein （PCPV） in 9 （56.3%）, and the left inferior phrenic vein in 9 patients （56.3%）. Although flow direction itself cannot be determined from CT-MIP, this modality provided clear images of the inflowing and the outflowing vessels. Moreover, in one patient, short gastric veins were not seen on conventional angiographic portography images of the spleen, but were clearly revealed on CT-MIP. CONCLUSION： We suggest that CT-MIP should be considered as a routine method for detecting and diagnosing collateral veins in patients with gastric varices scheduled for B-RTO. Furthermore, CT-MIP is more useful than endoscopy in verifying the early therapeutic effects of B-RTO.

适用于聚变堆三种典型的低活化材料是铁素体钢，V合金以及SiC/SiC复合物。日本研究了调节这些材料的物质成分以增加浅土埋藏率。由日本核安全委员会测定的裂变废的不能看估可以通过浅土埋藏处理的低水平废话的（LLW）。这趾为废话的有超过极限浓度值的任何单一放射性核素，从而造成单个剂量为100μSv·y^-1。聚变堆中产生的放射性核素的极限浓度值是根据核安全委员会的方法学推导出的。根据现在的材料成分估算采用三种低活化材料的聚变动力堆产生的生废物的放射性核素浓度。放射性废物分为低水平废物（LLW）和中等水平废物（MLW）。MLW被定义为不符合LLW的废物。因为1个或更多的放射性核素都超过了推导出的极限浓度值。发现在LLW和MLM总和之中MLW的重量百分率为：铁素体钢店10％，V合金占54％和SiC/SiC占43％。研究了通过物质成分调节来减少MLW重量百分率的可能性。发现，如果能把V合金中的Nd杂质含量以及SiC/SiC复合物中的N杂质含量减少，就能够大大地减少MLW百分率。另一方面，必需减少合金成分材料（W）中的含量，以进一步减少在用铁素体钢P82H情况下MLW的百分率。
