Comparison of the Omentum, Pleura and Diaphragm for Tracheal Autograft Neovascularization in Rats

Study objectives: Pleura, diaphragm, pericardial fat pad, intercostal muscles and omentum can be used to protect and revascularize the bronchial suture line. To compare the efficiency of pleura, diaphragm and omentum, an experimental study was designed.

Design: Heterotopic tracheal autotransplantation was performed in 15 rats.

Interventions: The animals were divided into 3 groups. The heterotopic tracheal segment was transplanted into omentum, diaphragm and pleura cavity.

Measurements and Results: The tracheal Segment Necrosis segment.The pleural and diaphragmatic groups showed the least necrosis and there was significant statistical difference among these groups and the omental group. (p<0.05)

Conclusions: Our study showed that the pleura and diaphragm could be used as safely as omentum for protection and neovascularization of bronchial suture lines
