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.{{cite web|title=Revascularization|url=http://medical-dictionary.thefreedictionary.com/revascularization|work=Medical Dictionary|publisher=The Free Dictionary|access-date=24 March 2013}} Vascular bypass and angioplasty are the two primary means of revascularization.
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 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.{{Citation needed|date=August 2008}}
Applications
For coronary artery disease (ischemic heart disease), coronary artery bypass surgery and percutaneous coronary intervention (coronary balloon angioplasty) are the two primary means of revascularization.{{cite web | last = Kalyanasundaram | first = Arun| title = Comparison of Revascularization Procedures in Coronary Artery Disease | work = Drugs, Diseases, and Procedures | publisher = Medscape | date = April 5, 2012 | url = http://emedicine.medscape.com/article/164682-overview | access-date = 2017-11-10 }} When those cannot be done, transmyocardial revascularization or percutaneous myocardial revascularization, done with a laser, may be an option.
Treatment for gangrene often requires revascularization, if possible.{{cite journal|last1=Mills JL|first1=Sr|last2=Conte|first2=MS|last3=Armstrong|first3=DG|last4=Pomposelli|first4=FB|last5=Schanzer|first5=A|last6=Sidawy|first6=AN|last7=Andros|first7=G|last8=Society for Vascular Surgery Lower Extremity Guidelines|first8=Committee|title=The Society for Vascular Surgery Lower Extremity Threatened Limb Classification System: risk stratification based on wound, ischemia, and foot infection (WIfI).|journal=Journal of Vascular Surgery|date=January 2014|volume=59|issue=1|pages=220ā34.e1ā2|pmid=24126108|doi=10.1016/j.jvs.2013.08.003|doi-access=free}} The surgery is also indicated to treat ischemic wounds (inadequate tissue perfusion) in some forms of chronic wounds, such as diabetic ulcers.{{cite journal |author=Gottrup F |title=A specialized wound-healing center concept: importance of a multidisciplinary department structure and surgical treatment facilities in the treatment of chronic wounds |journal=Am.
