Abstract:

Objective To investigate the architecture and arterial blood supply of porcine diaphragm, and explore the feasibility of esophagus repair using diaphragm. Methods 6 anesthetized mongrel Landrace were perfused with gelatin-lead oxide mixture and underwent CT scanning. The acquired images were input into the computer to perform 3-dimensional reconstruction. The origin, course and branches of the diaphragmatic arteries were analyzed. After that, diaphragms were incised and underwent X-ray for exploring the phrenic distribution of different arteries and their anastomosis with each other, and compared with that of anatomic measurement of diaphragm. Results The location and structure of the porcine diaphragm was different with that of human being. It's blood supply was mainly from the musculophrenic artery, posterior intercostal artery, pericardiacophrenic artery and phrenic artery. Their trunks and major branches can be clearly disclosed by the 3D images. X-ray images disclosed their abundant diaphragmic distribution and anastomosis. Conclusions Considering the architecture and blood supply of porcine diaphragm, it is possible to take diaphragm tissue flap pedicled with phrenic artery to repair esophagus.
