No results posted yet for this study

Summary

The primary objective of this study is to evaluate the relative intraoperative improvement in perfusion between arterial reconstruction and sympathectomies with quantitative ICG. A minimum of 40 patients, 20 Sympathectomy Prior to Bypass (group 1) and 20 Bypass Prior to Sympathectomy (group 2), will be recruited for this study. This study will enroll participants in a one to one randomized study design. There is the potential risk of loss of confidentiality. The study involves the intraoperative assessment of perfusion by quantitative ICG. ICG is FDA approved for this usage and will be used according to its labeling. Assessment involves intraoperative quantitative ICG data, questionnaires, and patient and physician assessments. There are no additional physical risks associated with participating in this study over and above that of the planned arterial reconstruction (bypass) and sympathectomies.The information collected will be kept confidential and will comply with the HIPAA.

PROCEDURE

Order of two elements of surgical procedure

Please see the arm/group descriptions for the order of elements of the surgical procedure in group 1 and group 2.

DRUG

Indocyanine Green

Intraoperative ICG has been validated to correlate to postoperative outcomes. ICG is administered by means of peripheral or central intravenous access, is excreted exclusively by the liver into the bile, and is not associated with risk for nephrotoxicity. We will be using a concentration of 2.5mg/cc. 12.5mg will be administered at each injection of ICG. Complete washout of the ICG occurs after 15 minutes, plenty of time considering the interval surgery that must occur. As per the protocol, ICG will be administered 3 times during the surgery. The patients will receive a total of 37.5mg of ICG, well below the recommended threshold of 2mg/kg. No significant toxic effects have been observed in humans with the high dose of 5 mg/kg of body weight.
