Percutaneous Coil Embolization for the Treatment of a Giant Brachial Artery Pseudoaneurym in a Child

True brachial artery aneurysm: A case report and review of literature

Introduction

A true brachial artery aneurysm is a rare pathology with an incidence of 0.17% of all peripheral artery aneurysms. This pathology can manifest devastating complications if overlooked, however, a high index of suspicion coupled with a thorough history and physical allows easy diagnosis. We present a rare case of the oldest documented patient with a true brachial artery aneurysm with idiopathic etiology.

Presentation of case

An 83-year-old gentleman presented with left upper extremity pain, erythema, and swelling for 1 week. He denied trauma to the area. Examination revealed a pulsatile mass of the antecubital fossa and decreased distal pulses. Imaging illustrated a 9mm aneurysm of the brachial artery with stenosis of the radial artery and non-enhancement of the origin of the ulnar artery. The patient underwent a brachial aneurysm excision, radial and ulnar embolectomy, and brachial to ulnar and radial artery bypass. Postoperatively, palpable pulses were appreciated in the radial and ulnar arteries. Pathology demonstrated a true aneurysm. The patient's postoperative course was uneventful and follow-up 6 months later revealed normal perfusion.

Discussion

This case highlights the importance of maintaining a high index of suspicion coupled with a thorough history and physical examination when encountering neurovascular complaints of the upper extremities. Operative intervention even in asymptomatic patients is warranted due to a high complication rate of 33%.

Conclusion

More research into the pathophysiology of this rare pathology is needed to further understand, prevent, or mitigate its complications.

A false aneurysm of internal mammary artery: A case report

A false aneurysm of the internal mammary artery is a very rare clinical entity. Early and accurate diagnosis and treatment of false aneurysms of internal mammary artery are critical, as it may result in rupture, severe bleeding, and even death. Currently, endovascular therapeutic approaches such as stenting and coil embolization have been considered the first-line treatment. Herein, we report a case of false aneurysm of the internal mammary artery in the light of literature data.

Acute Upper Limb Ischemia Due to Delayed Presentation of a Brachial Artery Pseudoaneurysm Post-Venipuncture

Brachial artery pseudoaneurysms (BAPs) are rare but could lead to complications of high morbidity. We report a case of a BAP presenting with hand ischemia and median nerve neuropathy nearly a decade after the inciting iatrogenic trauma, successfully treated with excision and direct repair. This report highlights that untreated pseudoaneurysms can be indolent and present late with both symptoms of embolization and local compression.
