: Long duration of anesthesia may induce toxicity in the developing brain. However, little is known about the effects of the combination of surgery and anesthesia on the developing brain. The mechanisms for the effects are not clear. To determine these effects, postnatal day 7 male and female Sprague-Dawley rats were exposed to 3% sevoflurane for 2 h with or without right common carotid exposure. Pyrrolidine dithiocarbamate (PDTC), an anti-inflammatory agent, was given 30 min before and 6 h after the carotid exposure...

BACKGROUND Ischemia-reperfusion injury of whole brain involves a complicated pathophysiology mechanism. Dexmedetomidine (Dex) has been shown to have neuro protective functions. This study observed the effect of Dex on serum S100B and cerebral intracellular adhesion molecule-1 (ICAM-1) in a rat model of cerebral ischemia-reperfusion. MATERIAL AND METHODS Healthy Sprague Dawley (SD) rats (males, 7 weeks old) were randomly divided into sham, model, and Dex groups (n=20 each). A cerebral ischemia-reperfusion model was prepared by clipping of the bilateral common carotid artery combined with hypotension...

The carotid-cavernous fistula (CCF) is a rare complication in patients victimized by craniofacial trauma. It involves multidisciplinary medical action. Owing to its potential complications, it is essential that maxillofacial surgery and neurosurgery specialists diagnose this condition so that appropriate treatment can be performed. The authors present a report of a case 11 years after the surgery.

Though the variations of vertebral artery are clinically asymptomatic yet abnormalities are of diagnostic importance either prior to vascular surgery in the neck region or in patients of intravascular diseases such as arteriovenous malformations or cerebral aneurysms. Therefore, the aim of the study is to bring out 2 variations in the configuration of vertebral artery and their clinical implication. During dissection of thorax of 2 female cadavers, 2 different variants of configurations of left vertebral arteries were observed...

During rodent experiments, the caudal ventral artery (CVA) is useful for blood pressure (BP) measurement. However, CVA measurements may not reflect the true BP. This study was performed to verify the site-specific accuracy of invasive arterial BP monitoring during surgery in rats. Invasive arterial BP was simultaneously measured in rats via the CVA and the common carotid artery (CCA). The BP values were analysed while the rats were subjected to cooling of the head or tail. Additionally, the rats underwent digital subtraction angiography and histological examination of these arteries...

BACKGROUND: Moyamoya disease is an idiopathic progressive cerebrovascular steno-occlusive disorder characterized by the formation of numerous collaterals called moyamoya vessels. Accurate evaluation of vascular status and CBF is needed for prompt treatment to prevent ischemic and/or hemorrhagic events. The pathogenesis of the ivy sign on fluid attenuated inversion recovery (FLAIR) images of moyamoya disease patients is unclear. We report a moyamoya disease case wherein the ivy sign changed in relation to SPECT-measured CBF during progression and following treatment...

OBJECTIVE: Randomized trials support carotid endarterectomy (CEA) in asymptomatic patients with ≥60% internal carotid artery (ICA) stenosis. The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Our goal was to determine the natural history stroke risk of asymptomatic patients who might have undergone CEA based on consensus statement PSV of ≥230 cm/s but instead were treated medically based on more conservative CDUS imaging criteria...

BACKGROUND: Perioperative care for patients undergoing carotid endarterectomy (CEA) often presents a challenge to the anesthesia provider, as this patient group commonly suffers from a wide range of comorbidities. Although clinical trials could not demonstrate a significant benefit associated with regional anesthesia for outcomes such as insult, cardiac infarction or mortality, many authors concur that regional anesthetic techniques might be preferential in specific patient populations for this type of surgery...

In atherosclerosis studies, there are few data, especially in men, on the biology of perivascular adipose tissue (PVAT) compared to that of other adipose tissue (AT), on amendments in obesity, and its possible role in the development of atherosclerosis. We conducted an ex vivo human study on pericarotid adipose tissue-collected in the immediate vicinity (PVATp) and away from the plate (tapas)-and subcutaneous (SC) neck gathered during surgery from patients suffering from atheromatous carotid disease. In addition, we conducted a study in obese Zucker rats (models of obesity and insulin resistance) and Wistar rats subjected to moderate stress...

The author has encountered a 67-year-old man with dural arteriovenous fistula (AVF) presenting as a non-traumatic chronic subdural hematoma (CSDH). This previously healthy patient was hospitalized due to progressive headache with subacute onset. He underwent burr-hole surgery twice for evacuating the left CSDH that was thickest at the posterior temporal area. The operative procedure and finding was not extraordinary, but subdural hematoma slowly progressed for days following the revision surgery. After investigation by super-selective external carotid angiography, a dural AVF found near the transverse-sigmoid sinus was diagnosed...

Bilateral cavernous carotid aneurysms (CCAs) are often not amenable to neurosurgical clipping or endovascular coiling. Here, we report the case of a 50-year-old female who presented with a 1-year history of gradual severe headache. Preoperative angiograms revealed bilateral CCAs. Among these findings, the right giant CCA had been trapped after the external carotid artery-saphenous vein-middle cerebral artery (ECA-SV-MCA) bypass 8 years prior. Additionally, the left CCA was again trapped after the internal maxillary artery-radial artery-middle cerebral artery (IMA-RA-MCA) bypass, followed by parent artery occlusion (PAO), because of the enlargement of a 0...

Positron emission tomography with (15)O-labeled gases ((15)O-PET) is important for in vivo measurement of cerebral oxygen metabolism both in clinical and basic settings. However, there are currently no reports concerning (15)O-PET in mice. Here, we developed an (15)O-PET method applicable to mice with spontaneous respiration of (15)O-gas without a tracheotomy catheter. Sequential (15)O-PET was also performed in a mouse model of chronic cerebral hypoperfusion with bilateral common carotid artery stenosis (BCAS) induced by placement of microcoils...
