Abstract A case is presented in which the sudden onset of bitemporal hemianopsia was caused by partial thrombosis associated with enlargement of an unruptured anterior communicating artery aneurysm. The features of the sequential computed tomographic scans resembled those of pituitary apoplexy, reemphasizing the necessity for cerebral angiography in preoperative evaluation. The clinical significance of the warning signs of cerebral aneurysm during the era of computed tomography is discussed. (Neurosurgery 22:564-566, 1988)

Thromboembolic stroke from migration of thrombus formed in non-giant intracranial aneurysms is a recognized but rare event. We describe a case of partial thrombosis of a 7 mm anterior communicating artery aneurysm, which embolized to the right callosomarginal artery in the brief time interval between two sequential diagnostic angiograms performed as part of elective endovascular coiling, and before any instrumentation had been advanced into the intracranial circulation. To our knowledge, this is the first reported case of aneurysmal thrombus embolization observed angiographically in near real time.

RUPTURED ANTERIOR COMMUNICATING ARTERY ANEURYSMS TREATED BY COILING TECHNIQUE: CHARACTERISTICS, OUTCOMES AND PROGNOSISES Abstract A prospective study of 31 patients with ruptured anterior communicating artery aneurysm (ACoA) treated by endovascular coiling was carried out at Stroke center - Hue Central Hospital, from September 2018 – February 2020. The results obtained were: Male:female ratio = 2.1: 1, age 54.2 ± 15.3 (21-85); clinically sudden onset 100%, headache 87.1%, vomiting 45.2%, cranial nerve palsy 12.9%, hemiparesis 29%, aphasia 11%; Hunt-Hess 1-3 61.3%, Fisher 1-3 35.2%, Glasgow coma score ≤8 19.4%; aneurysm size 5.6 ± 2.0 mm (2.5-10 mm), complete obliteration 81%; delayed ischemia 19.4%, ventricular dilation 45.2%, in-hospital recurrent hemorrhage 0%, modified Rankin scale (mRS) 0-2 at discharge 51.6%; mRS 0-2 after 3 months 54.8%, in-hospital death 0%, death within 3 months 22.6%. There was a moderate correlation between Hunt-Hess, Glasgow score at admission and mortality within 3 months; there was a statistically significant relationship between Glasgow coma scale-based groups and mortality (OR 0.34; 95% CI: 0.12 - 0.99; p = 0.047, p-value 77.4%).

We describe a misleading case of a partially occluded A1 segment duplication that mimicked an ACoA aneurysm on computed tomography angiography and conventional angiography and led to surgical intervention. The location of such an anomaly at the ACoA on the side of least hemodynamic stress may provide a clue to recognizing this variant.

AbstractA fenestration tube is a clipping reconstruction technique that allows the preservation of critical vessels in aneurysm surgery. A patient with a ruptured anterior communicating artery (ACoA) aneurysm with a posterior projection was admitted to our neurosurgery unit. A right dominant A1 with rotation of the A2 fork was observed on preoperative computed tomography angiography (CTA). During surgery, we observed that the recurrent artery of Heubner branched off the A2 just distal to the neck of the aneurysm. Successful clipping was achieved by building an “A1–A2 fenestration tube,” with preservation of the recurrent artery and of the ACoA perforators. Surgical nuances and the advantages of fenestration tubes are discussed.

A 75-year-old woman underwent Gamma Knife surgery (GKS) for a vestibular schwannoma. Eight years after GKS, she suffered sudden onset of headache. Computed tomography revealed diffuse subarachnoid hemorrhage around the cisterns of the posterior fossa. Right vertebral artery angiography showed an aneurysm arising from the lateral pontomedullary segment of the left anterior inferior cerebellar artery. The aneurysm was not located at a branching site. Trapping of the distal anterior inferior cerebellar artery aneurysm was performed, and the aneurysm was removed. The pathological features of this aneurysm are discussed. This aneurysm was diagnosed as a pseudoaneurysm pathologically. This is the first report of aneurysm formation with pathological findings following GKS for a vestibular schwannoma.

A 44-year-old patient developed paraplegia following rupture of an anterior communicating artery aneurysm. There was no evidence of any spinal lesion. Cerebral angiography showed a paired bihemispheric disposition of the A2 segment. We report this case and consider the anatomical variants of the A2 segment described in literature. The paired bihemispheric variant was reported in 21% of the cases. An azygos (unpaired) artery was observed in 5% and a triplicated A2 segment in 20% of the cases.

A 65-year-old woman presented to the emergency department with sudden onset of left-sided weakness, headache and vomiting. A cerebral CT showed an acute intracerebral haemorrhage involving the right caudate nucleus and lentiform nucleus with mild midline shift and intraventricular extension. CT angiography did not reveal aneurysm or other vascular anomaly. Conventional cerebral angiography demonstrated a 3 mm right medial lenticulostriate branch aneurysm, arising from the right anterior cerebral artery (ACA). Endovascular treatment was performed from the left internal carotid via the anterior communicating artery into the right ACA. Complete occlusion was achieved with injection of N-butyl-2-cyanoacrylate. The patient had neurological rehabilitation during hospitalisation followed by outpatient physical therapy. Two years later, clinical follow-up demonstrated excellent recovery.
