We describe the case of a 69 year-old man who presented with repeated episodes of irregular jerking movements in the bilateral upper and lower extremities, precipitated by standing up. Cerebral angiograms revealed occlusion of both internal carotid arteries, and the patient's symptoms responded to targeted blood pressure management. Physicians should be mindful of bilateral limb-shaking TIAs when presented with bilateral paroxysmal events that can mimic seizures or orthostatic hyperkinesia.

We report a 77-year-old woman with marked enlargement of a middle cerebral artery (MCA) aneurysm 4 years after the successful intra-aneurysmal embolization of an ipsilateral large internal carotid artery (ICA) aneurysm. She intially presented with right third cranial nerve palsy due to a large ICA aneurysm, 20.8 mm in diameter. Initial magnetic resonance angiography (MRA) revealed a signal decrease in the right MCA, suggesting hemodynamic disturbance based on the contrast pooling in the right large ICA aneurysm exhibiting “Windkessel phenomenon”.

We report a case of reversible cerebral angiopathy after viral infection in a pediatric patient with genetic variant of RNF213 mutation. The patient had developed a severe headache after hand, foot, and mouth disease.

CONCLUSIONS: Despite the greater inherent complexity, procedural and long-term clinical outcomes following PCI of distal LM trifurcations with everolimus-eluting stents in a modest-sized cohort from the EXCEL trial were similar compared with treatment of distal LM bifurcation disease without trifurcations. These findings support PCI as a treatment strategy for selected patients with distal LM trifurcation disease. PMID: 31793882 [PubMed - as supplied by publisher]

ConclusionBaseline cut off thrombus appearance predicts a  higher number of thrombectomy maneuvers. In day to day practice this may prepare the neurointerventionalist for a more challenging endovascular procedure ahead. Stroke etiology, clinical outcomes and thrombus-specific characteristics did not show any associations with the thrombus appearance.

This study assessed the efficacy of a pro-thrombotic VTA targeting phosphatidylserine (PS) in a radiation-primed AVM animal model. The model AVM was surgically created in rats by anastomosis of the left external jugular vein to the adjacent common carotid artery. After 6  weeks, the AVM was irradiated (20 Gy) using gamma knife surgery (GKS). A PS-targeting VTA was created by conjugation of annexin V with human thrombin and administered intravenously 3 weeks post-GKS or sham. Unconjugated thrombin was used as a non-targeting control. AVM thrombosis and occlusion w as monitored 3 weeks later by angiograph...

Authors: Rashid MK, Singh K, Bernick J, Wells GA, Hibbert B, Russo J, So DY, Le May MR, CAPITAL PCI Group Abstract BACKGROUND: A pharmacoinvasive strategy for ST-segment elevation myocardial infarction (STEMI) management combines the use of fibrinolysis with the routine transfer to coronary angiography, with percutaneous coronary intervention (PCI) if needed. This method reduces the risk of major adverse cardiovascular event (MACE) compared with fibrinolysis alone; however, it is associated with higher bleeding risk. We sought to assess the bivalirudin compared with unfractionated heparin (UFH) used during PCI as p...

Abstract: A 34-year-old man with chronic neck pain was treated with regular cervical paravertebral ozone injections. After his last injection, he experienced a syncopal episode and, upon awakening, was found to have ataxia, aphasia, hemiparesis, and left sixth nerve palsy. Computed tomographic angiography demonstrated intra-arterial gas in the right vertebral artery; multiple posterior circulation infarcts were seen on brain MRI. This case illustrates the potential dangers of paravertebral injections of ozone.

Introduction: To assess the differences of completion angiography after carotid endarterectomy between local and general anesthetic approach. Our secondary outcomes were to evaluate the relationship between intraoperative reparations and postoperative strokes; and to assess the usefulness of external carotid reparation when it was occluded during the procedure.
