Right Subclavian Artery Aneurysm

Abstract

Subclavian artery aneurysms are rarely seen in the clinical setting, representing 1% of all peripheral artery aneurysms. The cause of a subclavian artery aneurysm is variable, and the symptoms are sometimes vague. Although other nonsonography imaging modalities are more likely to incidentally diagnose a subclavian artery aneurysm, sonographers must be aware of a subclavian artery aneurysm as a possible incidental finding to help prevent a potential fatal rupture.

Mycotic subclavian artery aneurysms: a scoping review

“…Initial antimicrobial therapy was mentioned for 18 patients [7-9, 12, 16, 18, 19, 21, 23, 24, 26, 29, 31-33, 35, 37]. The antibacterial drugs were antibacterial agents (cefotaxime, ceftazidime, cephalexin, meropenem, or vancomycin) for 14 (77.8%) patients, both antibacterial Pleural effusion (1) [31] Bronchial wash and brushings (1) [27] Unknown (4) [9,32,34,37] Methicillin sensitive staphylococcus aureus [8,11,17,22,28,30] 6 Blood (4) [11,17,22,28] Hickman line tip (1) [11] Pus (1) [22] Surgical specimen (1) [30] Unknown (1) [8] Wound tissue (1) [28] Surgical specimen (1) [17] Escherichia coli [16,24] 2 Blood (1) [24] Urine (1) [24] Pus (1) [16] Methicillin-resistant staphylococcus aureus [23,25] 2 Blood (1) [23] Wound tissue (1) [25] Staphylococcus aureus [35] 2 Blood (1) [35] Wound tissue (2) [35] Streptococcus viridans [15,35] 2 Blood (1) [15] Wound tissue (1) [35] Streptococcus pneumoniae [10] 2 Pus (1) [29] Surgical specimens (1) [10] Burkholderia pseudomallei [33] 1 Blood (1) [33] Surgical specimen (1)…”

“…Subclavian artery aneurysms (SAAs) are very rare, representing about 1% of peripheral arterial aneurysms [1]. The underlying etiologies of SAA formation include atherosclerosis, thoracic outlet syndrome, collagen disorders, infection [2] and iatrogenic or traumatic injuries [3].…”
