Evaluating the effects of a surgical technique on gastrointestinal function in patients with aortic dissection

Impact of Retrograde Inferior Vena Cava Perfusion on Gastrointestinal Function in Patients Undergoing Surgical Repair for Acute Type A Aortic Dissection: A Study Protocol and Prospective Evaluation.

The Second Hospital of Nanjing Medical University · NCT06434987

This study is testing if a special surgical technique called Retrograde Inferior Vena Cava Perfusion can help improve gut function and reduce complications for patients recovering from surgery for aortic dissection.

What this trial studies

This study investigates the impact of Retrograde Inferior Vena Cava Perfusion (RIVP) on gastrointestinal function in patients undergoing surgical repair for Acute Type A Aortic Dissection (ATAAD). It aims to assess whether RIVP can reduce ischemic reperfusion injury and inflammatory responses that may compromise gastrointestinal integrity during and after surgery. The study will compare postoperative gastrointestinal complications in patients receiving RIVP alongside standard surgical procedures. By focusing on this often-overlooked aspect of patient recovery, the research seeks to enhance overall outcomes following ATAAD repair.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 who are scheduled for surgical repair of Acute Type A Aortic Dissection under cardiopulmonary bypass.

Not a fit: Patients with pre-existing gastrointestinal conditions or those on certain medications that affect gut microbiome may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved gastrointestinal health and recovery for patients undergoing surgery for aortic dissection.

How similar studies have performed: Previous studies have shown promising results with RIVP in reducing organ dysfunction, suggesting potential for success in this area, although specific gastrointestinal outcomes require further investigation.
