Aneurysm of Persistent Primitive Hypoglossal Artery Occluded with Guglielmi Detachable Coils

Abstract

<jats:p> The persistent primitive hypoglossal artery is rare remnant of one of the four embryonal carotid-basilar anastomoses. It is present in 0.02–0.26% of all cerebral angiogram. 14 cases of PHA aneurysms have been reportede in the literature and as far as we know no case in which endovascular embolization was used as a treatment. We present a case with subarachnoid haemorrhage due to aneurysm of persistent primitive hypoglossal artery. The aneurysm was successfully occluded with Guglielmi detachable coils. The SAH resolved and recovery was uneventful. </jats:p>

Persistent hypoglossal artery aneurysm: Case report and qualitative systematic review

“…Following inclusive wide-ranging literature search, over 700 abstracts were included for analysis (Figure 3), after review 24 articles were included for the qualitative study (Tables 1 and 2). 8–30 In total, 24 aneurysms (25 including this study) have been treated in relation to a PHA, 18 have been with surgery and six (seven including this study) with endovascular therapy. The majority of these aneurysms are reported to have occurred at the hypoglossal-basilar artery junction whilst six (seven including this study) have specified an aneurysm relating to the PICA origin.…”

Anaesthetic management of a case of giant cerebral aneurysm with persistent hypoglossal artery

“…[9,10] Aneurysms in carotid basilar anastomotic vascular malformations can be diagnosed with MR angiogram, CT scan and DSA. These can be treated by either endovascular coiling [11] or surgical clipping. A proper understanding of the anatomy and physiology of the brain, protection of the posterior circulation, cerebral protection, continuous monitoring and maintaining transmural pressure gradient by maintaining stable haemodynamics are essential for successful anaesthetic management.…”
