its means an injections that literally goes directly into an artery. Most injections are not given this way, but are instead injected into a large muscle. The particulars situation you are describing often happens with in advertant epi-pen sticks. Somebody fumbles an epi=pen while trying to administer it and it constricts the bloodvessels in teh hand and fingers. Most peopel don't realize the sseverity of teh situation until they lose the fingers or hand

Intra arterial injection means injecting drugs into the arteries which bring blood from heart to other tissues away from the heart. Blood go back to the heart through the veins.Injections of drugs are normally given through the veins. Accidental injection of drugs into the the artery can cause the wall of the artery to constrict, shutting off blood supply to tissues that artery supplies. Clot can also form by giving Intra arterial drug injection. However, intra arterial injection is used in special cases to deliver anticancer drugs to tumors like liver cancers or skin cancer like malignant melanoma
Injection of radioactive substances into the arteries is carried for some special radiological investigations.
