Abstract
Brachial artery aneurysms are rare disease that can be encountered. It is divided into true and false. The frequency of true aneurysm of the brachial artery is so much unusual. So, we present a case of a 59 year old male who presented to us with complaint of mass in left upper limb since many years ago. Now, there was sudden onset of progressive pain with coldness, numbness, tingling sensation and blackish discolouration of skin from 8 hours. The left upper limb was pulseless and color Doppler ultrasound showed a non-pulsatile aneurysm at the mid level of left brachial artery associated with arterial occlusion in its distal branch by thrombus. The patient was successfully revascularised by interposing a saphenous vein graft. Thus,this case suggest that the prompt diagnosis of true brachial artery aneurysm by ultrasound or color Doppler ultrasound and the proper treatment by surgical repair can save limb from dangerous sequel Keywords: brachial artery aneurysm; color doppler ultrasound; true aneurysm; ultrasound.
Highlights
Aneurysms are abnormal dilatations of the vessel wall that classified as true and false (Pseudo) types
True aneurysm is the localized dilation involving all three layers of the arterial wall, but a false type or pseudo aneurysm is a collection of flowing blood that communicates with the arterial lumen and filled only by the adventitia or surrounding soft tissue.[10]
The USG and color Doppler USG findings was suggestive towards the true aneurysm that showed arterial wall and no visible blood flow within the mass which differentiate it from vascular tumor (Figure 1,2)
Summary
Aneurysms are abnormal dilatations of the vessel wall that classified as true and false (Pseudo) types. A 59 year old male referred to our radiodiagnosis department with complain of mass in left upper limb Pradhananga et al True Brachial Artery Aneurysm Presenting as a Non-Pulsatile Mass
