Prevention of Colon Ischemia During Aortic Aneurysm (AAA) Repair - Full Text View

Sponsor:	Spectros Corporation
Collaborators:	Stanford University University of California
Information provided by:	Spectros Corporation
ClinicalTrials.gov Identifier:	NCT00671203

Purpose

Patients undergoing surgery on their Aorta can get ischemia, a lack of blood flow, to their intestines and colon. This is very serious, as 2 out of 3 patients who have this problem die before leaving the hospital. A device developed by Spectros, called T-Stat, is approved by the US FDA to detect ischemia, and has been reported to detect ischemia in AAA aneurysm surgery and stenting, allowing the surgeon or interventional radiologist to take action quickly, while the colon ischemia is still treatable.

This purpose of this study is to establish how T-Stat can best be used to prevent deaths.

Further study details as provided by Spectros Corporation:

Primary Outcome Measures:

Detect colon ischemia early [ Time Frame: Just before, and during, surgery or stenting ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Allows change in the untreated course of colon ischemia [ Time Frame: 28 days or discharge from hospital ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	500
Study Start Date:	June 2007
Estimated Primary Completion Date:	September 2009 (Final data collection date for primary outcome measure)

Intervention Details:

If ischemia is detected, and the detection in consistent with the physician's clinical view, blood flow to the colon is established using any of the known techniques that would be used had the diagnosis been made in the absence of T-Stat, which include changes in the deployment of stents and/or coils, reanastomosis, reimplantation, or stenting, of obstructed vessels, or other established techniques.
