OBJECTIVE The evaluation of the venous neurovasculature, especially the dural venous sinuses, is most often performed using MR or CT venography. For further assessment, diagnostic cerebral angiography may be performed. Three-dimensional rotational angiography (3D-RA) can be applied to the venous system, producing 3D rotational venography (3D-RV) and cross-sectional reconstructions, which function as an adjunct to traditional 2D digital subtraction angiography. METHODS After querying the database of Baylor St...

In patients with major cerebral artery disease, lower blood pressure might reduce blood flow in the collateral pathways, thereby impairing the growth of cerebral collaterals, inhibiting hemodynamic improvement. We evaluated the hemodynamic status twice using positron emission tomography and (15)O-gas, over time, in 89 medically treated patients with atherosclerotic internal carotid artery or middle cerebral artery disease that had no ischemic episodes during follow-up (mean, 28 ± 23 months). Changes in the mean hemispheric values of hemodynamic parameters in the territory of the diseased artery at follow-up were correlated with the mean blood pressure values at the baseline and follow-up examinations...

Temporary parent vessel clip occlusion in aneurysm surgery is not always practical or feasible. Adenosine-induced transient cardiac arrest may serve as an alternative. We retrospectively reviewed our clinical database between September 2011 and July 2014. All patients who underwent microsurgical clipping of intracranial aneurysms under adenosine-induced asystole were included. A total of 18 craniotomies were performed, and 18 aneurysms were clipped under adenosine-induced asystole (7 basilar arteries, 8 internal carotid arteries, 1 middle cerebral artery, and 1 anterior communicating artery) in 16 patients (10 females, 6 males)...

REVIEW
Torstein R Meling
Treatment of blood blister-like aneurysms (BBAs) of the supraclinoidal internal carotid artery (ICA) is challenging and the optimal treatment is yet to be defined. The treatment options for ICA BBAS are microsurgery, endovascular therapy, or a combination of the two. The microsurgical armamentarium consists mainly of direct aneurysm clipping with or without protective EC-IC bypass, clip-wrapping, or trap ligation with ICA sacrifice with or without EC-IC bypass. The endovascular treatment options are mainly endovascular ICA ligation, multiple overlapping stents (≥ 3) with or without coiling, covered stents, or flow diverters...

In the United States, 90% of carotid intervention is being performed for asymptomatic carotid stenosis, even though 90% of patients would be better treated with intensive medical therapy. This is being justified by comparing risks of stroke or death with medical therapy during clinical trials completed decades ago (approximately 2% per year) with risks of intervention with carotid artery stenting (CAS) versus carotid endarterectomy in recent trials that did not have a medical arm. Such extrapolations are, simply put, invalid...

Carotid stent angioplasty (CAS) has been shown to protect patient from future stroke long-term efficacy similar to carotid endarterectomy (CEA). The risk of minor stroke in the perioperative period is higher than with CEA and not related to cerebral protection during the CAS procedure since a significant portion of the neurologic events occur between 1 and 30 days following stent deployment. This observation suggests mechanisms integral to the stent itself may be pertinent such as plaque embolization thru the stent struts may occur...

Prior clinical trials produced evidence-based treatment recommendations for patients with asymptomatic carotid stenosis that may not be appropriate for clinical decision-making today. High-quality patient outcomes data to allow informed decision making regarding the optimal management of high-grade asymptomatic internal carotid artery stenosis is lacking. The results of the Asymptomatic Carotid Atherosclerosis Study were published in 1995 based on a randomized patient enrollment in the 1990s. Outcomes after endarterectomy, stenting, and medical treatment for these patients have all improved in the subsequent 2 decades...

BACKGROUND: Hemodynamic changes frequently occur after carotid artery stenting (CAS), and in some patients these changes, particularly hypotension, may be prolonged. There are discrepant results for predicting patients at high risk for these prolonged hemodynamic changes and identifying the effect on clinical outcome. In this study, we aimed to determine the frequency, predictors and consequences associated with prolonged hypotension (PH) after CAS in our center. METHODS: We retrospectively analyzed the demographics, risk factors, nature of carotid disease, degree of stenosis of both internal carotid arteries, stent diameter and site of dilatation during stenting in 137 CAS procedures...

Spontaneous dissection of cervical arteries (sCAD) is a major cause of ischemic stroke in young patients, with an incidence varying from 1.7 to 3/100,000/year for extracranial internal carotid artery (ICAD) and 1 to 1.9/100,000/year for extracranial vertebral artery (VAD). Reliable epidemiological data on stroke incidence related to sCAD are scarce in Italy. This study aims to evaluate the incidence, clinical features, and outcome of cerebrovascular events related to sCAD and spontaneous intracranial arteries dissections (sIAD) in the city of Pisa (Italy)...

A novel hypothesis proposes that "cardio-cephalic neural crest (NC) syndrome," i.e. cephalic NC including cardiac NC, contributes to the concurrent occurrence of vascular diseases in the cardio- and cerebrovascular regions. NC is a transient structure present in early embryogenesis. Cephalic NC provides mesenchymal cells to the vascular media in these regions. Concurrent cardio- and cerebrovascular lesions have been reported in PHACE syndrome, ACTA2 mutation syndrome, and less frequently in the spontaneous occlusion of the circle of Willis (so-called moyamoya disease)...

BACKGROUND: Multiple dissections rarely occur with ruptured vertebral artery dissecting aneurysms (VADAs). Here, we report three cases of ruptured VADA concurrent with spontaneous cervical internal carotid artery (ICA) dissection. CASE DESCRIPTION: None of the three patients had a history of vasculopathy or trauma. All ruptured VADAs were treated with internal coil trapping in the acute stage of subarachnoid hemorrhage (SAH). Rebleeding was not observed in any patients after the treatment...

Based on standard carotid endarterectomy, we performed modified carotid endarterectomy in two cases of carotid artery stenosis by changing the direction of the carotid artery incision to avoid restenosis of the internal carotid artery without using a patch. The two patients recovered smoothly without any complications. Compared with eversion or patch endarterectomy, this modified carotid endarterectomy avoids restenosis of the carotid artery and shortens operation time.

OBJECTIVE The middle clinoid process (MCP) is a bony projection that extends from the sphenoid bone near the lateral margin of the sella turcica. The varied prevalence and morphological features of the MCP in populations stratified by age, race, and sex are unknown; however, the knowledge of its anatomy and preoperative recognition on CT scans can aid greatly in complication avoidance and management. The aim of this study was to further illustrate the surgical anatomy of the parasellar region and to quantify the incidence of MCP and caroticoclinoid rings (CCRs) in dried preserved human anatomical specimens...
