Q

aetiology of sublcavian artery aneurysms

A
-Post-stenotic. This is related to the thoracic outlet -syndrome –arterial type (a- TOS)
· Non-specific degenerative type 
· HIV-related
· Intimo-medial mucoid degeneration
· Tuberculous aneurysms 
· Trauma
· Fibromuscular dysplasia (FMD)
2
Q

clinical features of subclavian artery aneurysms

A
· Upper limb ischaemia
· Brachial plexus compression
· Limb swelling (venous compression)
· Stroke (rare complication)
· Hoarseness
· Stridor
· Pulsatile mass
3
Q

treatment of subclavian artery aneurysms

A

symptomatic = needs treatment
asymptomatic and < 2.5cm = observation
- open surgical repair
- endovascular repair with covered stent

4
Q

aetiology of extracranial carotid aneurysms

A
· Non-specific degerative
· HIV-related
· Tuberculous
· Trauma
· Anastomotic - following carotid surgery
5
Q

clinical features of extracranial carotid aneurysms

A
· Pulsatile mass
· Stroke
· Transient ischaemic attacks(TIAs)
· Hoarseness
· Stridor
· Dysphagia
· Odynophagia
· Nerve compression (e.g.hypoglossal n, facial n)
· Horner’s syndrome
6
Q

treatment of extracranial carotid aneurysms

A

open surgical repair

endovascular repair - trauma patients or to avoid sternotomy - not advised for infected aneurysms

7

which vessels are involved in mesenteric aneurysms

A

Splenic artery aneurysms (60%)
hepatic artery aneurysms (20%)
superior mesenteric artery aneurysms (6%).

8
Q

aetiology of mesenteric artery aneurysms

A

11
Q

morphology of renal artery aneurysms and where they are found

A

90% of true renal artery aneurysms are extrarenal

75% of these are sacular

12

clinical features of renal artery aneurysms

A
· Most are asymtomatic and detected on routine angio- imaging
· Pain
· Haematuria
· Renovascular hypertension
· Rupture =most feared complication.
