University of Ottawa Identifier:
First received: December 13, 2005
Last updated: NA
Last verified: November 2005
History: No changes posted
The purpose of this study is to determine whether skeletonization of the internal thoracic artery leads to improved flow, increased length, improved sternal perfusion, and decreased pain and dysesthesia in patients undergoing coronary artery bypass surgery

Condition Intervention
Coronary Artery Disease Procedure: Skeletonization of the internal thoracic artery

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Skeletonized Versus Non-Skeletonized Internal Thoracic Artery Harvest for Coronary Artery Bypass Grafting

Further study details as provided by University of Ottawa:

Primary Outcome Measures:
  • Intra-operative Internal Thoracic Artery Flow measure prior to coronary anastomoses

Secondary Outcome Measures:
  • - Internal Thoracic Artery length
  • - Sternal Perfusion (SPECT imaging)
  • - Post-operative pain and dysesthesia

Estimated Enrollment: 48
Detailed Description:
Traditional harvesting of the internal thoracic artery (ITA) for use as a conduit in coronary bypass surgery involves the dissection of a rim of tissue surrounding the artery on either side. Although the benefits of ITA use are well established, there are certain limitations to its routine use. Recent studies, primarily observational, have suggested that skeletonization of the ITA (i.e. harvesting of the ITA alone) may overcome some of these limitations by improving conduit flow, increasing length, and reducing the risk of deep sternal infection in high risk patients. Furthermore, skeletonization of the ITA can potentially preserve intercostal nerves and reduce post-operative pain and dysesthesias associated with ITA harvesting. In order to assess the effects of ITA skeletonization, this is a prospective, randomized, within-patient study design in patients undergoing coronary artery bypass grafting.
