[Minimally invasive access to the abdominal aorta in pigs].

Experiments were conducted on 10 sows weighing 50-60 kg. Animals were randomly divided into two experimental groups comprising 5 individuals each. Surgical procedure of reaching the abdominal aorta below the renal arteries was performed using two different methods. In animals from the first group the procedure involved cutting the linea alba in order to obtain access to the abdominal aorta through the abdominal cavity. In the second group the access to the abdominal aorta was obtained by retroperitoneal approach. The approach was made in lower lateral one-third of the abdomen cutting through the muscles and without opening the peritoneal cavity. The study showed superiority of the second surgical method over the median approach along the linea alba in the form of: better animal survival (100% of animals), shorter procedure time, lack of postoperative complications, shorter recovery period and better general postoperative condition
