Haemorrhagic Nonsecreting Pituitary Adenoma Associated with Persistent Primitive Trigeminal Artery

We describe a case of intra-arterial treatment (IAT) of acute posterior circulation occlusion in a patient with a persistent primitive trigeminal artery (PPTA). The patient presented with an acute left sided hemiparesis and loss of consciousness (Glasgow coma score of 5). Computed tomography angiography showed an acute occlusion of the right internal carotid artery (ICA), the PPTA, distal basilar artery (BA), right posterior cerebral artery (PCA), and right superior cerebellar artery (SCA). Stent-retriever assisted thrombectomy was not considered possible through the hypoplastic proximal BA. After passage of the proximal ICA occlusion, the right PCA and SCA were recanalized through the PPTA, with a single thrombectomy procedure. Ten days after intervention patient was discharged scoring optimal EMV with only a mild facial and left hand paresis remaining. PPTA is a persistent embryological carotid–basilar connection. Knowledge of existing (embryonic) variants in neurovascular anatomy is essential when planning and performing acute neurointerventional procedures.

Saccular Aneurysms

Object. The aim of this study was to determine the prevalence of cerebral saccular aneurysms in patients with persistent primitive trigeminal artery (PPTA). The prevalence of cerebral saccular aneurysms in patients with PPTA previously has been reported to be 14 to 32%, but this rate range is unreliable because it is based on collections of published case reports rather than a series of patients chosen in an unbiased manner.Methods. The authors retrospectively evaluated their own series of 34 patients with PPTA to determine the prevalence of cerebral aneurysms in this population. The prevalence of intracranial aneurysms in patients with PPTA was approximately 3% (95% confidence interval 0–9%).Conclusions. The prevalence of intracranial aneurysms in patients with PPTA is no greater than the prevalence of intracranial aneurysms in the general population.
