Acute limb ischemia due to diclofenac sodium iatrogenic intra-arterial injection: a case report.

Unlabelled: Diclofenac sodium is a nonsteroidal anti-inflammatory, the injection of which by the intra-arterial route can lead to serious vascular complications, including limb ischemia.

Case Presentation: We report the case of accidental intra-arterial injection of diclofenac sodium in the brachial artery leading to acute limb ischemia.

Clinical Discussion: Iatrogenic intra-arterial injection is rarely reported in the literature; however, it is toxic and can lead to limb amputation. Only two cases of intra-arterial injection of diclofenac have been reported in the literature. The proposed pathophysiological mechanism is vasospasm, intravascular thrombosis, and chemical endoarteritis. The most common anatomical location in accidental intra-arterial injection is the antecubital fossa, where branches of the ulnar and brachial arteries are more superficial.

Conclusion: The injection of medication must be as careful as possible, since the intra-arterial injection can affect the functional prognosis of the organ.
