Mycotic Aneurysm of Brachial Artery Secondary to Infective Endocarditis

Surgical treatment of a rare brachial artery aneurysm post-arteriovenous fistula closure after kidney transplant: A case report

BACKGROUND

Brachial artery aneurysms are defined as dilations greater than 50% of the normal diameter, which are rare among all peripheral arterial aneurysms. While they are often present as pseudoaneurysms, true brachial artery aneurysms are also detected rarely. In this case report, the surgical repair method of true brachial artery aneurysms, which is a rare condition, is explained.

CASE SUMMARY

Herein, we present a 61-year-old male patient with complaints of swelling and pain in the right arm antecubital region that had been progressing over 6 mo. Upon the diagnosis of a true brachial artery aneurysm associated with arteriovenous fistula, the aneurysm was surgically repaired with an autologous saphenous vein graft. The patient was discharged without any neurovascular complications postoperatively.

CONCLUSION

True brachial artery aneurysms are rare and there are not any recommendations for their management in the current literature. Even though the treatment of true aneurysms in this artery is primarily based on a surgical treatment, endovascular repair also might be an option.

Surgical Treatment of Multiple Venous and Arterial Aneurysms Due to Arteriovenous Malformations of the Arm

Introduction

Arteriovenous malformations (AVMs) are rare, especially in elderly patients. Occasionally, AVM can produce aneurysmal degenerations, which can lead to bleeding or rupture. The aim of this case report was to describe the surgical treatment of large arterial and venous aneurysms in the arm associated with an AVM.

Report

An 83 year old woman of White ethnicity who was a non-smoker presented with a large pulsatile aneurysm at the left elbow with paresis of the first three fingers. The diagnosis was made by duplex ultrasonography (DUS), computed tomography angiography (CTA), and arteriography. Additional tests confirmed aneurysms of the brachial artery and the outflow veins, with the largest more than 7 cm in diameter. A very proximal brachial artery bifurcation and increased venous flow were noted. DUS confirmed the AVM by showing continuous flow in the axillary vein. The decision for surgical resection involved vascular surgeons, radiologists, angiologists, and anaesthetists. Treatment involved opening and excision of multiple venous aneurysms and AVMs. A short segment of the aneurysmal brachial artery was also resected and repaired with end to end anastomosis. The deep brachial artery which supplied AVMs and venous aneurysms was ligated and excision of these lesions was performed. At one year follow up, there were no complications and the revascularisation was patent.

Discussion

Arterial and venous aneurysms occurring together with AVMs are rare and not well documented in the medical literature. In this case, surgical intervention, including resection with direct anastomosis of the arterial aneurysm coupled with excision of venous aneurysms and AVM, proved to be effective, as evidenced by stable post-operative outcomes after one year.

Late-onset mycotic aneurysm of brachial artery secondary to infective endocarditis: case report

Infective endocarditis remains a dreaded and severe disease because of its course, its complications, its need for good antibiotic management, as well as its morbidity. Peripheral mycotic aneurysm is a rare complication of infective endocarditis. We report the case of a 62-year-old female patient who presented with Streptococcus SPP infective endocarditis treated by antibiotics. Two months later, she presented with a mycotic aneurysm of the right brachial artery with the same germ, we have performed a brachial artery ligation, then a complete revascularization by graft of the saphenous vein. Through this case, we should not forget that the lesional assessment is always necessary to avoid missing serious complications that could threaten the functional prognosis, even vital.

True Idiopathic Brachial Artery Aneurysm Treated With a Saphenous Vein Graft

Purpose: The objective of this study is to report a case of a 65-year-old woman who presented with pallor and pain of her left arm secondary to a true arterial brachial aneurysm, which was successfully treated with saphenous vein bypass and embolization of the aneurysm sac. A review of the literature is also presented. Case report: A 65-year-old woman presented with an acute onset of pallor and pain of her left forearm, and hand. On physical examination, there was a pulsatile mass at the forearm. A doppler ultrasound showed a fusiform aneurysmal dilatation of the brachial artery of 23 mm of diameter. A dynamic contrast-enhanced MRI angiogram confirmed a fusiform dilation of the distal brachial artery. The patient was scheduled for open repair. A fusiform 20 x 60 mm aneurysm of the distal brachial artery extending to the cubital fossa was found and a brachial artery to radial and ulnar arteries bypass with interposed reverse right saphenous vein was created. Embolization of the aneurysm sac was performed using Gelita-spon ® (Gelita Medical, Eberbach, Germany). A final angiogram showed an adequate perfusion through the bypass to the hand, and no contrast in the aneurysmal sac. Postoperative course was uneventful with discharge on the fourth postoperative day. Conclusion: Revascularization with autologous saphenous vein graft and exclusion of the aneurysm with local embolization is a good treatment alternative in a patient with symptomatic brachial aneurysm with distal embolization.

True Brachial Aneurysm in an Older Female Patient. A Case Report and Review of Literature

INTRODUCTION

Brachial artery aneurysms constitute 0.5% of peripheral aneurysms. These can be true or secondary to trauma or arteriovenous fistulas. These present as an asymptomatic pulsatile mass or may cause symptoms due to compression of adjacent neurological structures.

CASE REPORT

We present a review of the literature on clinical, histological, and therapeutic characteristics of true brachial aneurysms, motivated by the case of a 67-year-old woman with an asymptomatic pulsatile mass dependent on the brachial artery of the left arm who underwent open surgical correction with resection of the aneurysmal sac and interposition of great saphenous vein graft with adequate postoperative results.

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.
