  • Embolisation of the right Gastric Artery in patients undergoing hepatic arterial infusion chemotherapy using two possible approach routes.
    The British journal of radiology, 2010
    Co-Authors: Takuji Yamagami, Rika Yoshimatsu, Tomohiro Matsumoto, Koshi Terayama, Hiroshi Miura, Tsunehiko Nishimura
    Abstract:

    We used a retrospective non-randomised study to investigate the clinical effect of selective embolisation of the right Gastric Artery before hepatic arterial infusion chemotherapy (HAIC) using a port-catheter system. We evaluated whether the hepatic Artery or the left Gastric Artery is the better approach for selecting the right Gastric Artery. A total of 367 patients (244 men and 123 women; mean age, 64.1 years) with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system. In 294 of these patients, right Gastric arterial embolisation with microcoils was attempted before placement of the port-catheter system to prevent Gastric mucosal lesions. Approach was either through the hepatic Artery (175 patients) or through the left Gastric Artery (119 patients), with success rates in catheterising the right Gastric Artery of 78.3% and 77.3%, respectively. If the attempt was unsuccessful, the catheter was redirected to the alternative approach, which increased the final success rate to 96.3%. Only seven patients experienced gastroduodenal mucosal lesions acutely after HAIC, as revealed by endoscopy. Embolisation of the right Gastric Artery is a feasible procedure that can reduce the incidence of Gastric mucosal lesions associated with HAIC. Approach through either the hepatic Artery or the left Gastric Artery is equally acceptable.

  • Embolization of accessory left Gastric Artery to prevent acute Gastric mucosal lesions in patients undergoing repeated hepatic arterial infusion chemotherapy.
    Acta radiologica (Stockholm Sweden : 1987), 2007
    Co-Authors: Takuji Yamagami, Takeharu Kato, Tatsuya Hirota, Rika Yoshimatsu, Tomohiro Matsumoto, Tsunehiko Nishimura
    Abstract:

    Purpose: To retrospectively evaluate results of selective embolization of the accessory left Gastric Artery prior to repeated hepatic arterial infusion chemotherapy using a port-catheter system.Material and Methods: Of 22 patients with unresectable advanced liver cancer who underwent percutaneous implantation of a port-catheter system, an accessory left Gastric Artery was revealed by arteriography in 16 patients before and in six patients after port-catheter implantation. The right Gastric Artery was embolized to prevent Gastric mucosal lesions in all 22 patients. In addition, the accessory left Gastric Artery was selectively embolized for the same purpose using from one to six microcoils, which were from 3 to 5 mm in diameter. Within 10 days after implantation, arteriography was performed while contrast material was infused via the port.Results: Selective embolization of the accessory left Gastric Artery was successful in all 22 patients. No complication related to embolization of this Artery occurred in...

  • Efficacy of the left Gastric Artery as a route for catheterization of the right Gastric Artery.
    AJR. American journal of roentgenology, 2005
    Co-Authors: Takuji Yamagami, Takeharu Kato, Tatsuya Hirota, Shigeharu Iida, Tsunehiko Nishimura
    Abstract:

    OBJECTIVE. Our aim was to evaluate the efficacy of the left Gastric Artery as a route for embolization of the right Gastric Artery before port-catheter implantation for hepatic Artery infusion chemotherapy.MATERIALS AND METHODS. In 88 patients (61 men and 27 women; mean age, 63.4 years; range, 25–83 years) with unresectable advanced liver cancer, retrograde catheterization of the right Gastric Artery through the left Gastric Artery was performed to embolize the right Gastric Artery.RESULTS. The right Gastric Artery was successfully catheterized and embolized in 79 patients (89.8%). In two of the nine patients in whom the procedure was not successful, we found that no right Gastric Artery existed after we succeeded in retrograde advancement of the microcatheter toward the hepatic site. The only procedure-related complication was misplacement of a microcoil into the hepatic Artery site in two patients.CONCLUSION. The left Gastric Artery is an appropriate route for selective embolization of the right Gastric...

  • Embolization of the right Gastric Artery before hepatic arterial infusion chemotherapy to prevent Gastric mucosal lesions: approach through the hepatic Artery versus the left Gastric Artery.
    AJR. American journal of roentgenology, 2002
    Co-Authors: Takuji Yamagami, Takeharu Kato, Shigeharu Iida, Toshiyuki Nakamura, Tsunehiko Nishimura
    Abstract:

    OBJECTIVE. The purpose of our study was to evaluate whether the hepatic Artery or the left Gastric Artery is the better route of approach for selective embolization of the right Gastric Artery before hepatic arterial infusion chemotherapy using a port-catheter system.SUBJECTS AND METHODS. Eighty-six patients (56 men, 30 women; mean age, 62.1 years) with unresectable advanced liver cancer underwent percutaneous implantation of a port-catheter system. In the 75 patients who had not undergone gastrectomy, right Gastric Artery embolization was performed before port-catheter system placement to prevent Gastric mucosal lesions. In 43 patients, the approach for embolization was through a microcatheter inserted from the hepatic Artery site, and in the remaining 32 patients, the approach was from the left Gastric Artery. The success rates of these two groups were compared.RESULTS. Embolization was successfully accomplished at the first attempt in 72.1% of the 43 patients in whom the microcatheter was inserted from...
