Apraxia of ocular movements is often present with bilateral lesions. Balints syndrome Some patients with bilateral occipital or parietooccipital infarctions present with Balints syndrome.[notes.medicosnotes.com]
We present case series of seven patients of PCA dissecting aneurysms that were treated with endovascular therapy. Clinical and radiological presentation, technique, and follow-up data are presented.[frontiersin.org]
CASE REPORT A 17-year-old male patient was admitted to a different institution than ours complaining of blurred vision, headache, and three episodes of generalized tonic-clonicseizures, which had occurred 3 months before his admission.[surgicalneurologyint.com]
Further workup may include referral to a geneticist for evaluation of potential genetic or metabolic causes of stroke in these populations.[clevelandclinicmeded.com]
He is still being given a noninterventional treatment combined with clinical follow-up.[surgicalneurologyint.com]
Endovascular treatment has been utilized as a modality of treatment of this rare entity [3]. But the proper choice of the treatment and the long term results are yet to be clear.[austinpublishinggroup.com]

Conclusion Endovascular therapy for the treatment of dissecting aneurysms of the PCA is safe and effective.[frontiersin.org]

Keywords: Stent-assisted coil embolization; Hemorrhagic P1 dissection; Posterior cerebral artery Introduction Hemorrhagic dissecting aneurysms of cerebral artery tend to rebleed and the prognosis after rebleeding is poor.[austinpublishinggroup.com]
As shown here, newer generation stent-retrievers can also achieve rapid and complete arterial recanalisation of distal thrombus in the posterior circulation preventing an increase in the ischaemic volume, which appears to directly affect the clinical prognosis[ejmint.org]
Although alertness generally returns, prognosis for good functional recovery is poor because of severe memory dysfunction. The syndrome may result from a “top of the basilar” artery embolus. The artery of Percheron may be involved.[emedicine.medscape.com]
Prognosis This will depend on the extent of disease; however: Acute basilar artery occlusion has a very high mortality rate. Vertebrobasilar stroke usually leaves significant neurological deficits.[patient.info]
They are large-artery atherosclerosis, embolism, small-vessel disease, stroke of other determined etiology, and stroke of undetermined etiology.[clevelandclinicmeded.com]
In spite of thorough diagnostic evaluation, the etiology of PCA territory infarction cannot be determined in at least one quarter of patients.[ncbi.nlm.nih.gov]
CLINICAL-ANATOMIC CORRELATION Infarction in the distribution of different cerebral arteries often produces distinctive clinical syndromes, which can facilitate anatomic and etiologic diagnosis and help guide treatment.[neupsykey.com]
Various etiologies are suggested including infectious (syphilis, mycotic), migraine, cystic medial necrosis, fibromuscular dysplasia, homocysteinuria, mixed connective tissue disease, and trauma ( Hamada et al., 2005 ).[frontiersin.org]
Risk factors Once the appropriate acute therapies (if any) are instituted, the history should be directed at cerebrovascular risk factors and contributing historical elements that may reveal the underlying etiology.[emedicine.medscape.com]

Palinopsia, micropsia, and macropsia These are illusory phenomena that are of uncertain pathophysiology. Palinopsia describes the persistence of a visual image for several seconds to days in a partially blind hemifield.[emedicine.medscape.com]
The suggested pathophysiological mechanisms for this growth include successive aneurysmal wall dissections;[ 8 ] recurrent hemorrhages from proliferated intramural capillaries;[ 15 ] and the presence of intrathrombotic endothelized vascular channels.[[surgicalneurologyint.com]

Even with vertebral artery occlusion, collaterals (circle of Willis) may prevent ischaemia.[patient.info]
Optimization of stroke risk factor reduction is critical in both primary and secondary prevention.[clevelandclinicmeded.com]
Recognition of these may allow prevention of a stroke. Prodromal photopsias did not closely resemble the scintillating displays of migraineurs. When the stroke occurred, visual complaints usually predominated.[ncbi.nlm.nih.gov]
Identification of the underlying mechanism or risk factors is an important aspect of stroke prevention because it has implications for optimum preventive treatment—such as anticoagulation for atrial fibrillation.[bmj.com]
