Potential role of the neuropeptide CGRP in the induction of differentiation of rat hepatic portal vein wall.

2005

The media of the rat hepatic portal vein is composed of an internal circular muscular layer (CL) and an external longitudinal muscular layer (LL). These two perpendicular layers differentiate progressively from mesenchymal cells within the first month after birth. In this paper, we studied the development of calcitonin gene-related peptide (CGRP) innervation during post-natal differentiation of the vessel. We show that CGRP innervation is already present around the vessel at birth in the future adventitia but far from the lumen of the vessel. Progressively, CGRP immunoreactive fibers reached first LL then CL. CL by itself become only innervated at day 14 after birth. This corresponds to the…

Reperfusion of liver graft during transplantation: techniques used in transplant centres within Eurotransplant and meta-analysis of the literature

2013

Abstract: It remains unclear which liver graft reperfusion technique leads to the best outcome following transplantation. An online survey was sent to all transplant centres (n=37) within Eurotransplant (ET) to collect information on their technique used for reperfusion of liver grafts. Furthermore, a systematic review of all literature was performed and a meta-analysis was conducted based on patients' mortality, number of retransplantations and incidence of biliary complications, depending on the technique used. Of the 28 evaluated centres, 11 (39%) reported performing simultaneous reperfusion (SIMR), 13 (46%) perform initial portal vein reperfusion (IPR), 1 (4%) performs an initial hepati…

Embolization with ethylene vinyl alcohol copolymer (Onyx®) for peripheral hemostatic and non-hemostatic applications: a feasibility and safety study

2018

International audience; Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures.Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016. Demographic data, clinical presentation, underlying etiology, culprit vessel, endovascular procedure, pain during embolization, out…

Orthotope arterialisierte Lebertransplantation bei Ratten mit Stenttechnik der supra- und infrahepatischen v. cava

2003

The aim of this study was to establish a liver transplant model with a reduced warm ischemic period between cold preservation and completed anastomosis. Male brown Norway rats were used. A cuff was fixed in the portal vein, stents were inserted in the A. hepatica, the suprahepatic and infrahepatic v. cava and in the bile duct. After cross clamping of the recipient liver, another stent, occluded by a small pin, was introduced in the recipient suprahepatic v. cava. After ligation of this recipient suprahepatic caval stent the recipient liver was removed and the cold prepared donor liver was pushed forward along the pin and both suprahepatic stents of recipient and donor were connected. Then c…

Chirurgische Therapie von Lebermetastasen kolorektaler Karzinome

2003

Resection is the only curative treatment of colorectal liver metastases proofed by a long-term follow-up. The operation is indicated if the metastases are completely removable with sufficient liver parenchyma remaining after resection and if the patient is fit for surgery. The resection is not indicated in cases with non resectable extrahepatic tumours and lymph node metastases distal the hepatoduodenal ligament. The postoperative mortality amounts to about 5 % and the 5-year-survival-rates range between 20 and 40 % depending on the selection of patients. Aims of new concepts of operative therapy are the improvement of resectability by preoperative portal vein embolization, the resection co…

Resection of esophageal diverticulum through uniportal video-assisted thoracoscopic surgery

2018

Open surgery remains the standard strategy for management of esophageal diverticulum in symptomatic patients. However, in the last years an increasing number of minimally invasive approaches have been proposed for this issue in order to reduce the surgical trauma and favor a fast return to daily activity. Herein, we describe a novel technique as uniportal video-assisted thoracoscopic surgery (VATS) for performing resection of esophageal diverticulum. This procedure was successfully carried out in three consecutive patients with giant mid-esophageal diverticulum (mean size: 6.5±0.5 cm). The mean post-operative time was 121±10 minutes. The chest drain was removed 48 hours later in all cases a…

Duplexsonographie abdomineller Gefäße

1987

Duplex sonography is a non-invasive procedure which permits the determination of flow velocity and direction in visceral vessels. Results in 50 normals have shown that small arteries can be evaluated in about 50% of cases. The portal venous system can be demonstrated in all cases; average flow velocity and volume is 15.2 +/- 2.8 cm/s and 694 +/- 230 ml/min, corresponding with the values obtained by invasive methods. Clinical application for duplex examinations can be found in portal hypertension, varices, thromboses, aneurysms and transplant kidneys.
