Introduction
Aneurysm of extracranial carotid artery (ECAA) is an uncommon but important clinical entity
Incidence of intracranial carotid artery aneurysm (0.8 – 18 %) and ECAA is 1- 1.5 %
ECAA is less than 1 % of all carotid pathologies
Definition
The accepted difinition of most arterial aneurysm is 50 % increase in diameter compared to the normal diameter of artery.
But in case of carotid bifurcation diameter should be 200 % more than ICA / 150 % of CCA
Etiology
Degenerative / Atherosclerosis
Post traumatic causes
Postendarterectomy
Vasculitis
Connective tissue disorder
Mycotic Aneurysm /SABE
Clinical features
Pulsatile mass
Painful ,tender mass , fever
Neurological symptoms
Cranial nerve dysfunction
Dysphagia
Hemorrhage and rupture
Differential diagnosis
Tortuous , kinked /coiled carotid artery
Prominent carotid bifurcation
Cervical lymphnodes overlying the carotid bifurcation
CBT
Cervical metastatic disease
Branchial cyst
Cystic hygroma
Investigation
Duplex ultrasound – limitation ?
CTA ; Advantages
;bony anatomical landmark
;circle of willis
; brain imaging
Treatment
Surgical Reconstruction
Endovascular
Advantage Avoiding difficult dissection
Proximal control is difficult
Reduce the risk of cranial nerve injuries
CONTRAINDICATION
Unstable Thrombs
Very tortuous carotid arteries
Post procedure
Surgical reconstruction ; Aspirin
Endovascular treatment ; clopidogrel
: Aspirin
* Statins
Form 2010 – 2013 we have total 29 cases
Out of them 18 have surgical reconstruction
11 have endovascular procedure
European journal of vascular &
endovascular surgery From Jan 1998 to Dec 2011 ,50
consecutive interventions for ICA aneurysmal disease was performed
3 patients developed major stroke
6 patients had cranial nerve injuries
3 patients had Thrombosis
Conclusion; surgical treatment provided satisfactory early & long term result,selected patients with non infected aneurysm endovascular option seems to be feasile
