简介：

Overview

This protocol describes a novel surgical technique for reconstructing donor atrial cuff anterior wall defects during lung transplantation. The method involves rotating the donor posterior atrial flap to enhance the repair process.

Key Study Components

Area of Science

• Lung transplantation
• Surgical techniques
• Cardiac anatomy

Background

• Challenges in lung transplantation include donor scarcity and quality.
• Common injuries occur to the left atrial cuff during procedures.
• Excess donor pericardial and atrial tissues can be utilized for repairs.
• Retention of the intact posterior atrial wall is crucial for effective reconstruction.

Purpose of Study

• To improve the quality and utilization of donor lungs.
• To present a new technique for repairing left atrial cuff defects.
• To reduce anastomosis time and cold ischemia time during lung transplantation.

Methods Used

• Positioning the patient and disinfecting the surgical area.
• Preparing the donor lung and performing necessary dissections.
• Trimming the posterior atrial wall to form a flap for repair.
• Anastomosing the atrial cuffs using continuous sutures.

Main Results

• The new technique effectively repairs anterior wall defects in vivo.
• Postoperative pulmonary artery systolic blood pressure was significantly lower.
• No significant differences in pulmonary systolic blood pressure among groups.
• Right atrial cuff anastomosis time was shorter for the new technique.

Conclusions

• The posterior atrial flap technique enhances donor lung utilization.
• It offers a feasible strategy for repairing left atrial cuff defects.
• The method is more convenient and reduces surgical time.
