Pseudoaneurysm of the Anterior Interosseous Artery and Anterior Interosseous Nerve Palsy. A Rare Postoperative Complication of Ulnar Fracture Osteosynthesis: A Case Report.

Peripheral arterial pseudoaneurysm is an uncommon complication after open reduction and internal fixation of bone fractures. Here, we describe a rare case of a 72-year-old man who developed a delayed pseudoaneurysm of the anterior interosseous artery after open reduction and internal fixation of an isolated ulnar fracture (nightstick fracture). He presented with a painful forearm mass and anterior interosseous nerve (AIN) neuropathy. Though rare, the appearance of AIN neuropathy is a potential complication of forearm fractures' fixation that should be diagnosed early and managed with a prompt and appropriate treatment.

A delayed diagnosis that altered the professional orientation of an athlete with upper limb chronic arterial embolization.

BACKGROUND: Vascular disorders of the upper extremity in young and physically active patients present a complex and challenging problem for the treating physician. Initial presentation may often be subtle and the consequences of misdiagnosis, delayed diagnosis or mistreatment can be severe. CASE REPORT: In this report, we discuss a case of a young woman with chronic upper limb ischemia due to an arterial thoracic outlet syndrome in whom even though symptoms persisted over a number of years during which she frequently sought medical consultation, remained undiagnosed until finally presenting with limb-threatening ischemia. Furthermore, due to this delay, the patient was forced to withdraw from her professional carrier in athletics. CONCLUSIONS: A thoughtful and through approach combining the history, physical findings, and use of appropriate diagnostic aids will provide the physician and patient with the greatest opportunity for a satisfactory outcome. Furthermore, a delay in definitive treatment may not only cause health deterioration, but may also incur social, economic and occupational consequences.
