CoSeal for Hemostasis of Aortic Anastamoses

Status Completed

Clinical Trial Summary

Surgery on the aorta can be associated with significant blood loss. Most commonly this is due to bleeding at the site of aortic anastomosis. Surgical bleeding is associated with significant morbidity.

One way to prevent bleeding is to use a special glue (sealant) after performing large connections on the aorta. The goal of this study is to compare the different methods surgeons use to stop/prevent bleeding.

The study team will collect medical information about patients before, during, and after surgery on their aortas, including the methods used to prevent bleeding. This information may help doctors improve the way that they care for these patients.

Clinical Trial Description

Bleeding is a major complication of cardiac surgery, and a significant cause of morbidity and mortality [1-4]. Hemostasis can be challenging during complex cardiac surgery, particularly due to friability of the tissue, coagulopathy, poor visualization of the surgical field, and limited accessibility to bleeding sites [5]. Failure to achieve and maintain hemostasis and reinforce fragile tissue may result in additional bleeding, which can further reduce visualization, increase operative blood loss, lengthen surgery, increase the use of blood products, and contribute to postoperative complications and reoperation [1-4].

Postoperative bleeding is a significant concern in cardio-thoracic surgery. Bleeding, either intraoperative or postoperative, has been associated with extended in-hospital length of stay, reoperations, severe morbidity and death [12]. In addition to surgical technique, a variety of therapeutic agents are available to assist in hemostasis. Surgical sealants are used to prevent suture line bleeding when ligation or conventional methods are ineffective or impractical [13]. CoSeal® Surgical Sealant (CoSeal®, Baxter, Westlake Village, CA) is a synthetic polyethylene glycol (PEG) polymer [11, 13]. The polymers cross-link with proteins in the tissue and begin to gel in approximately 5 seconds and set within 60 seconds, forming a strong, flexible, clear, degradable hydrogel that adheres to both tissue and synthetic graft surfaces [11, 13-14]. A secure seal is maintained through covalent tissue bonds even under high pressures in vessels, such as the aorta [15]. The gel is completely resorbed within 30 days [14]. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
