Chronic lymphatico-venous bypass: surgical technique and aftercare in a porcine model

Peripheral Lymphatico-Venous Anastomoses

TI HE EXISTENCE of communications between the lymphatic and the venous systems has been established. These communications may occur in the lymph nodes or between the lymphatic vessels and the veins. With the advent of lymphography, these communications have assumed practical importance since they provide a route for the sudden entrance of significant amounts of oily contrast material into the b...

An augmented reality system in lymphatico-venous anastomosis surgery†

Indocyanine green lymphography, displayed as infrared image, is very useful in identifying lymphatic vessels during surgeries. Surgeons refer the infrared image on the displays as they proceed the operation. Those displays are usually placed on the walls or besides the operation tables. The surgeons cannot watch the infrared image and the operation field simultaneously. They have to move their ...

Peripheral lymphatico-venous anastomoses. Report of two cases.

Cerebral histopathology following portal venous infusion of bacteria in a chronic porcine model.

BACKGROUND The aim of this study was to histologically investigate brain damage after prolonged periods of bacteremia in pigs. METHODS Twenty-one pathogen-free Göttingen minipigs were anesthetized and instrumented with a femoral arterial, a pulmonary arterial, and through midline abdominal incision with a portal venous catheter. After craniotomy the superior sagittal sinus was cannulated. A l...

Hematological effects of a low-prime neonatal cardiopulmonary bypass circuit utilizing vacuum-assisted venous return in the porcine model.

Limiting hemodilution in neonates is difficult when extracorporeal circuits require priming volumes that are 2 to 3 times the blood volume of the newborn patient. This extreme hemodilution contributes to the development of significant postbypass coagulation disturbances. The purpose of this project was to design a low-prime neonatal bypass circuit and evaluate the coagulation status after reduc...
