Clinical impact of anatomical variation of the pancreas and its vascular supply
 Rousek, Michael ; Kachlík, David (advisor) ; Liška, Václav (referee) ; Šubrt, Zdeněk (referee)
Knowledge of the anatomy of the pancreas, its vascular structures and their anatomical variations is crucial for the hepato-pancreato-biliary surgeon. Some anatomical variations of the pancreas can cause specific diseases in patients. Our work aims to provide a detailed review of clinically important variations in the anatomical structure of the pancreas and its vascular supply. The other goal was to identify the clinically important anatomical variations in the two most frequently performed pancreatic resections. The next goal was to describe the vascular supply of postresection pancreatic remnants and to determine a potentially critical anatomical arrangement that could influence postoperative perfusion of the remnant. The results were confirmed in a retrospective analysis of the patients after pancreatic resections. The most critical variations in the vascular supply of the pancreas were identified as a result of the experiment. Critical anatomical variations in the vascular supply of the postresection remnant after pancreaticoduodenectomy were found. In these cases, the vascular supply of the pancreatic remnant is provided only through non-constant anastomosis between the splenic artery and the transverse pancreatic artery. In the retrospective analysis, these patients had a significantly...

Possibilties of Portal Vein Reconstruction During Surgical Treatment of Pancreatic Cancer - Experiment on a Large Animal
 Pálek, Richard ; Liška, Václav (advisor) ; Ryska, Miroslav (referee) ; Loveček, Martin (referee)
Possibilities of Portal Vein Reconstruction during Surgical Treatment of Pancreatic Cancer - Experiment on a Large Animal Introduction: Pancreatic cancer is a fatal malignancy that is known as one of the leading causes of cancer mortality worldwide. The only potentially curative treatment is radical surgical resection. Because of the lack of early symptoms, the diagnosis is usually made in advanced stages of the disease. In the majority of patients, the tumor is already locally advanced or it has distant metastases at the time of diagnosis. Pancreatic cancer tends to infiltrate the portal vein (PV) or the superior mesenteric vein (SMV). Nowadays, resection of infiltrated parts of PV/SMV is recommended in specialized centers. There are several established techniques of PV/SMV reconstruction. The use of allogeneic venous grafts seems to be a method with minimal risk of adverse effects but there is only limited experience with these grafts. The optimal anatomical origin of allogeneic venous grafts for PV/SMV reconstruction remains unknown. Aims: The aim of this experiment was to compare two types of allogeneic venous grafts used for PV reconstruction in a large animal model of pancreatico- duodenectomy. These grafts were harvested from the systemic venous system (inferior caval vein grafts - IVC grafts) and...
