Immediately after undergoing coronary bypass grafting using the left internal thoracic artery, a 59-year-old man developed left leg ischemia. Right-to-left femoral artery crossover bypass was performed and the ischemia resolved. A 72-year-old man developed left calf pain 12 days after a similar procedure; peripheral angiography revealed stenosis of the abdominal aorta and distal peripheral arteries, which did not require intervention.
Hypothermia plays an important role in radial artery vasospasm. Normothermic organ bath and verapamil-nitroglycerin solution alone or in combination relieve spasm of radial artery.
It can be commented that reducing the ambient temperature is more beneficial than modifying the laser wavelength on perforation rates. Therefore we suppose tumescent anaesthesia temperature is effective on perforation independently from the wavelengths or type of the laser fibre.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
