Severe Disturbance

A 54-year old male patient underwent stent reconstruction of the P1-2 segment of the left posterior cerebral artery (PCA) and concomitant coil embolization of a symptomatic giant partially thrombosed P1 segment aneurysm. After an uneventful postinterventional period, on the 7th day the patient developed severe disturbance of consciousness. The imaging workup demonstrated acute venous infarction in the midbrain, caused by the compressive occlusion of the median anterior pontomesncephalic vein by the aneurysm in the interpeduncular fossa.

Pial Arteriovenous Fistula

We present two cases of 17-year-old man and 10-year-old boy presenting with subarachnoid haemorrhage and a history of road traffic accident. One patient had dissecting aneurysm of the posterior cerebral artery (PCA), and the other patient had partially thrombosed aneurysm on CT angiography. On digital subtraction angiography of the second patient, there was formation of PCA pontomesencephalic vein pial arteriovenous fistula (PAVF). Both the patients underwent endovascular treatment: stent-assisted coiling for aneurysm and coiling with parent vessel occlusion for PAVF. There were no procedural complications. Follow-up angiography showed no residual aneurysm or fistula. Trauma is one of the recognised causes of dissection, and intracranial dissections can present as stenotic lesions, aneurysms or fistulas, depending on the pathology. Traumatic dissecting PCA aneurysm has been reported in only two case reports previously, and post-traumatic PAVF in PCA has not been reported.

Introduction Aneurysms of the posterior cerebral artery (PCA) represent ∼ 1% of all intracranial aneurysms and usually present with subarachnoid hemorrhage. Objective The aim of the present study is to describe the case of an adult man presenting a saccular aneurysm of the right PCA at the posterior half of the postcommunicating (P2P) segment, and to discuss the technical nuances of the approach and of the clipping process. Case Report An investigation of a chronic headache in a 55-year-old man found a saccular aneurysm located just posterior to the most lateral portion of the right cerebral peduncle. A digital subtraction arteriography revealed a 7.8 mm × 5.6 mm × 4.8 mm posterior-medial projecting aneurysm of the right PCA at the P2P segment. A subtemporal approach was performed with partial aspiration of the right parahippocampal gyrus for a better exposure of the vascular structures. A proximal temporary occlusion of the PCA was performed at the anterior half of the postcommunicating P2A segment. The aneurysm was clipped with two semi-curved clips. The patient presented an uneventful recovery and was discharged from the hospital on the third postoperative day without any additional neurological deficits. Conclusion Aneurysms of the PCA are an uncommon vascular disease that challenges the ability of the neurosurgeons due to their many anatomical nuances, to their vast number of perforators, and to the risk of bleeding. However, the operative management of aneurysms of the PCA is technically feasible, safe and effective when performed respecting microsurgical principles.

Introduction: Visual field loss is often the first sign of lesion of the anterior or posterior visual pathways. Screening for visual field defects should be a part of all routine eye examinations, mainly when neurological lesions are suspected. A confrontation visual field (CVF) test provide a rapid and practical method of visual field assessment, allowing the recognition of major neurological deficits. Materials and Research Methods: To report a case of posterior cerebral artery (PCA) stroke early suspected by CVF test. Case-Report: A 77 year-old male presented to our emergency department with vision blurring complaints and a strange sensation of a vision loss on one side on the left eye (OS), for the previous 15 days. He explained that symptoms initiated after an episode of dizziness followed by lipothymia. He denied diplopia or headaches. Past history revealed hypertension and diabetes as cardiovascular risk factors. The best corrected visual acuity was 20/25 on right eye (OD) and 20/60 on OS and pupillary reflexes were normal. CVF test was performed and showed a decrease on left hemicampus of OS. The biomicroscopy was normal and the fundus examination showed optic nerve edema bilaterally, also documented by Optical Coherence Tomography. Considering the findings and the history, neuroimaging and a neurological observation were requested. Computerized axial tomography revealed a hypodense lesion in right occipital posterior region, with hematic density. He was hospitalized for proper treatment with the diagnosis of posterior cerebral artery ischemic stroke, with further hemorrhagic transformation. Discussion: In acute stroke, visual disorders may form all or part of the initial presentation. Homonymous visual field deficits are well-known almost universal characteristics of PCA ischemia, however, due to the absent of cognitive impairment or speech problems associated to many cases, the diagnosis can be challenging at early stages. Our case-report highlights the importance of using CVF test to an immediate inspection of the peripheral visual field, in order to detect acute major defects, including homonymous deficits, to understand if a further prompt neurological examination is mandatory.
