AI Article Synopsis

  • The basilar bifurcation area is a common location for intracranial aneurysms and is associated with arteries supplying crucial brain regions.
  • This paper discusses a unique case where a basilar tip fenestration resulted in five perforating arteries, highlighting its importance for clinical awareness.
  • Understanding the complex neuroanatomy is essential for neurosurgeons and neurologists to avoid severe complications during neurovascular procedures.

Article Abstract

The basilar bifurcation region is a common site for intracranial aneurysms, as well as it gives rise to a group of perforating arteries that supply the mesencephalon and the thalamus. Complex vascular microanatomy poses a diagnostic and therapeutic challenge for neurosurgeons, neuroradiologists and neurologists. In this paper, we present a previously unreported case of basilar tip fenestration that gave rise to five perforating arteries: the artery of Percheron and four mesencephalic arteries. Due to invaluable clinical significance, the possibility of such a variant must be considered during performing various neurovascular procedures, since e.g., embolization of the fenestration misdiagnosed as an aneurysm would inevitably lead to severe neurological complications (consciousness disturbances, quadriplegia, and sensory loss). Comprehensive knowledge of the neuroanatomy and neuroembryology is crucial to safe execution of intracranial interventions.

This detailed case report presents and discusses the endovascular treatment of a large proximal basilar artery fenestrated aneurysm (PBAFA). Aneurysms occur rarely at the vertebrobasilar junction, with a moderate proportion of cases presenting fenestrations. Considering the high risk associated with posterior circulation aneurysms, including estimated rupture risk, periprocedural complications, or treatment difficulties in surgical procedures, endovascular treatment options are becoming increasingly favored, particularly considering the advancements in stent and flow diverter techniques.

Fenestration of the basilar artery is a well-known anatomical variant which can be misdiagnosed as arterial dissection. Misdiagnosis as an aneurysm is also possible and has been reported. A 41-year-old woman was referred to our hospital for evaluation of a suspected aneurysm of the proximal basilar artery trunk found on 1.

Article Synopsis
  • Basilar artery (BA) fenestration and its occlusion are uncommon, and performing mechanical thrombectomy in these cases carries significant complication risks.
  • A case study of a 75-year-old woman showed that thorough imaging techniques identified BA fenestration and an occluded limb, leading to a successful thrombectomy without complications.
  • Preoperative basi-parallel anatomical scanning (BPAS) helped in understanding the BA's structure, allowing for a safe and effective recanalization using specialized catheter techniques.

This is a case of a young male patient with no known prior risk factors who presented for acute-onset right-sided neurological deficits suspicious for stroke, and magnetic resonance angiography (MRA) identified the development of an occlusion at the level of a basilar artery (BA) fenestration in the setting of right vertebral artery occlusion. The patient was treated with dual-antiplatelet therapy in the hospital and was able to return to work shortly after discharge. The case provides insights into several possibilities for the clinical significance of BA fenestration and its potential causal or contributory relationship with ischaemic stroke of the brainstem.
