In medical and surgical therapy, revascularization is the restoration of perfusion to a body part or organ that has had ischemia. It is typically accomplished by surgical means. Vascular bypass and angioplasty are the two primary means of revascularization.
Arterial revascularization
c_7y67y78noyix
The term derives from the prefix re-, in this case meaning "restoration" and vasculature, which refers to the circulatory structures of an organ. It is often combined with "urgent" to form urgent vascularization. Revascularization involves a thorough analysis and diagnosis and treatment of the existing diseased vascula...
