Gastroduodenal Artery (gastroduodenal + artery)
Selected AbstractsAnatomy of the cystic artery arising from the gastroduodenal artery and its choledochal branch,a case reportJOURNAL OF ANATOMY, Issue 3 2000A. K. SARKAR Variations in the branching pattern of the common hepatic artery often occur and may be encountered during cholecystectomy. Variants of the cystic artery, its branches and relations with the biliary structures and blood vessels emphasise the importance of arterial dissection in biliary surgery. In this study, a rare variant of the cystic artery and its choledochal branch is described. The cystic artery arose from the gastroduodenal artery, passed anterior to structures in the free margin of lesser omentum and travelled a long distance before supplying the gall bladder. A long choledochal branch was noted accompanying the common bile duct. Surgical implications of this variation of the cystic and choledochal arteries are discussed. [source] Hepatic arterial cannulation using the side holed catheterJOURNAL OF SURGICAL ONCOLOGY, Issue 2 2005Masashi Watanabe MD Abstract Background Hepatic arterial infusion chemotherapy (HAIC) has been recognized as one of the effective treatments for patients with hepatic metastatic tumor. However it is difficult to perform HAIC in the long term without complications. This report describes the laparotomic approach using the side holed catheter, which is a novel method of implanting a catheter-port system. Methods and Results We designed a new anti-thrombotic catheter for HAIC. This catheter is tapered from 5F (diameter of shaft) to 3.3F (diameter at tip), and a side hole is opened 7 cm from the tip of catheter. This catheter is inserted from the gastroduodenal artery to the common hepatic artery (CHA), and the tip is put in the aorta or in the splenic artery. The side hole is adjusted distal to the CHA. In our surgical department, our new catheter was inserted in four patients at the time of their abdominal surgery. The cannulation was performed successfully in all patients. In two of them, HAIC was finished without problems at 6 months after starting, and two were still treated by HAIC at 9 and 8 months after starting. Conclusions Initial results from a study of a new method of implanting a catheter-port system in the hepatic artery using the new tapering side hole catheter suggest that this method may enable operators to avoid complicated selective coiling and may lower the incidence of hepatic artery occlusion in patients receiving long-term HAIC.

[source] Arterioportal shunting as an alternative to microvascular reconstruction after hepatic artery resectionBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 2 2004S. Kondo Background: Portal vein and hepatic artery resection and reconstruction may be required in radical surgery for biliary cancer. Microvascular reconstruction requires special equipment and training, and may be difficult to accomplish when the arterial stump is small, when there are multiple vessels or when the stump lies deep within the wound. This study examined the feasibility and safety of arterioportal shunting as an alternative to arterial reconstruction. Methods: Over 30 months, ten patients with biliary cancer (six bile duct and four gallbladder carcinomas) underwent radical surgery with en bloc resection of the hepatic artery and end-to-side arterioportal reconstruction between the common hepatic or gastroduodenal artery and the portal trunk. Results: No patient died. Complications included bile leakage in two patients and liver abscess in one. Routine angiography performed 1 month after surgery revealed shunt occlusion in three patients. Once the existence of hepatopetal arterial collaterals had been confirmed in the remaining patients, the shunt was occluded by coil embolization. Conclusion: Arterioportal shunting appears to be a safe alternative to microvascular reconstruction after hepatic artery resection. However, the safety of the procedure and its potential to increase the cure rate require further assessment in a larger series with a longer follow-up.
