intraarterialis

Intraarterialis is a Latin adjective used in medical terminology to denote something that occurs within an artery or is delivered through an arterial route. In English-language practice, the direct equivalent is intraarterial, whereas intraarterialis appears mainly in Latin-language texts or in formal nomenclature.

As a descriptor, intraarterialis appears in descriptions of procedures, drug delivery, or anatomical localization related to the arterial system.

In modern medicine, intraarterial administration is used to concentrate drugs in a target area and limit systemic exposure. Examples include intraarterial chemotherapy for certain cancers, intraarterial thrombolysis for select cerebrovascular events, and diagnostic or therapeutic intraarterial injections under imaging guidance.

Procedures require arterial access, usually via femoral or radial arteries, and imaging guidance such as angiography. Risks include arterial injury, vasospasm, thrombosis, embolism, bleeding, and infection.

The term derives from Latin intra- "within" and arterialis "arterial." In contemporary English, the preferred term is intraarterial.
