Revascularization is the process of restoring the functionality of an affected organ. Contrast this term with vasculature , which describes the circulatory structures of an organ.

Revascularization involves a thorough analysis and diagnosis and treatment of the existing diseased vasculature of the affected organ, and can be aided by the use of different imaging modalities such as magnetic resonance imaging, pet scan, CT scan, and X ray fluoroscopy.

This is a concept important in the subdisciplines of biomedicine which are concerned with the rehabilitation of important organs, such as the heart, liver, and lungs.

The term revascularization is also used in conjunction with other medical terms such as angioplasty, cardiac, and myocardial to denote specific forms of revascularization techniques.

Treatment for gangrene often requires revascularization, if possible.
