Bypass of thoracic aorta using axillofemoral shunt
Vascular Surgery
|November 1, 1975
Abstract:
A left thoracotomy was performed and the thoracic aorta was occluded for 1 hr. in 7 dogs following placement of an 8 mm. right axillary-to-femoral artery shunt. Postop serial blood urea nitrogen and creatinine levels showed no significant changes and pathological examination of the kidneys at 2 weeks showed no abnormalities. Neurological deficits were not observed, suggesting that an axillary-to-femoral bypass will maintain adequate perfusion to the lower body during cross-clamping of the thoracic aorta.

01:15Thoracic Aorta
The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
01:25Abdominal Aorta
Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

01:19Veins of Thorax
The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
