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.

Infectious Aneurysm

Intracranial infectious aneurysms are rare entities accounting for approximately 1- 6 % of all cerebral aneurysms and have high propensity of rupture associated with mortality. The principal risk factor is infective endocarditis and the management includes antimicrobial treatment with or without obliteration of the aneurysm by microsurgical or endovascular means. We present a young patient with intracranial infectious aneurysm who was successfully treated with endovascular coil embolization. A 20-years-old female with history of rheumatic heart disease presented with subarachnoid hemorrhage due to rupture of IIA associated with infective endocarditis. Cerebral angiogram revealed right distal posterior cerebral artery aneurysm. Echocardiography showed vegetation in mitral valve and blood culture was positive for Enterococcus faecalis. Antibiotic treatment was administered for 6 weeks. The follow-up angiogram showed an enlarging aneurysm. So, the patient underwent endovascular coil embolization of the aneurysm preserving the parent artery. There were no post-procedure deficits. Intracranial infectious aneurysm should be considered as a differential diagnosis in a patient with infective endocarditis presenting with focal neurological deficits or altered consciousness. Early diagnosis and individualized approach are the key to successful treatment and endovascular treatment is an effective modality for such lesions.

P2A (anterior) segment aneurysm of posterior cerebral artery is one of the rare aneurysm of posterior circulation. We report a case of 30 years old right handed young man who presented with features of SAH in Emergency Department and cerebral angiogram confirmed left posterior cerebral artery P2A segment thrombosedfusi form aneurysm. Postoperative recovery was good except left sided ptosis after microsurgical trapping via left temporal approach. Treatment modality and outcome after intervention for P2A segment aneurysm will be discussed. Nepal Journal of Neuroscience, Volume 14, Number 3, 2017, Page : 42-45

History Of

A 34-year-old female patient presented with a history of sudden loss of vision in right eye. On neurological examination, she was having visual agnosia in right eye. MRI was performed which revealed left posterior cerebral artery infarct. Trans thoracic echocardiography was performed. This showed a large left atrial myxoma. Patient underwent resection and had an uneventful postoperative course. This case report showed the importance of cardiac source of emboli in patients presenting as acute stroke. Performing echocardiography and diagnosing and treating cardiac source of emboli could prevent further complications.

✓ Improved access to the tentorial notch can be obtained by removal of the roof of the external auditory meatus in association with a low temporal craniotomy. This approach decreases temporal lobe retraction and the risk of venous infarction. This method was perfected in the surgical laboratory on five cadavers and was successfully performed in a patient with a giant aneurysm of the posterior cerebral artery.

Background and purpose The diagnosis and management of acute fetal posterior cerebral artery occlusion are challenging. While endovascular treatment is established for anterior circulation large vessel occlusion stroke, little is known about the course of acute fetal posterior cerebral artery occlusions. We report the clinical course, radiological findings and management considerations of acute fetal posterior cerebral artery occlusion stroke. Methods We performed a retrospective review of consecutive patients presenting with acute large vessel occlusion who underwent cerebral angiogram and/or mechanical thrombectomy between January 2015 and January 2021. Patients diagnosed with fetal posterior cerebral artery occlusion were included. Demographic data, clinical presentation, imaging findings and management strategies were reviewed. Results Between January 2015 and January 2021, three patients with fetal posterior cerebral artery occlusion were identified from 400 patients who underwent angiogram and/or mechanical thrombectomy for acute stroke (0.75%). The first patient presented with concomitant fetal posterior cerebral artery and middle cerebral artery occlusions. Thrombectomy was performed with recanalisation of the fetal posterior cerebral artery but the patient died from malignant oedema. The second patient presented with isolated fetal posterior cerebral artery occlusion. No endovascular intervention was performed and the patient was disabled from malignant posterior cerebral artery infarct. The third patient presented with carotid occlusion and was found to have fetal posterior cerebral artery occlusion after internal carotid artery recanalisation. No further intervention was performed. The patient was left with residual contralateral homonymous hemianopia and mild left sided weakness. Conclusion Fetal posterior cerebral artery occlusion is a rare, but potentially disabling, cause of ischaemic stroke. Endovascular treatment is feasible. Further investigation is needed to compare the efficacy of medical versus endovascular management strategies.

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.
