Severe upper extremity polyneuropathy due to inferior brachial plexus compression as a result of left subclavian artery pseudoaneurism

Abstract

In the present report, we describe the case of a 76-year-old hemodialysis patient who was admitted with clinical features of neurological thoracic exit syndrome due to subclavian artery pseudoaneurysm following the insertion of a dual lumen vascular internal jugular catheter (vascath) with excellent outcome after endo-arterial stent placement.

Complex Regional Pain Syndrome Type II Secondary to Endovascular Aneurysm Repair

“…Neuropathological symptoms arising from pseudoaneurysms are a moderately common complication, depending on location of the vessel wall malformation [ 6 , 7 ]. CRPS II, although notably rare sequelae, has been reported from catheter penetration through the femoral and radial arteries [ 9 , 10 ].…”

“…Pseudoaneurysms are a rare but existing complication of intravascular percutaneous access. Cases have been cited of pseudoaneurysm formation in the aorta, radial artery, and the brachial artery [ 1 – 6 ]. In the majority of these instances, the pseudoaneurysms rarely led to symptom development and when noticed were quickly operated on with no short- nor long-term effects.…”

“…An even fewer number of cases have reported minor neurological symptoms from postoperative pseudoaneurysm formation. From upper extremity polyneuropathy to brachial plexus compression, a wide array of symptoms have been reported [ 6 , 7 ]. Of note, brachial artery pseudoaneurysms have produced exclusive symptoms along the distribution of the median nerve [ 8 ].…”
