B) MR angiography shows a defect in the flow signal of the right internal carotid artery (white arrows) with preservation of the right middle cerebral artery. (bmj.com)

Procedure-related complications occurred in 38 aneurysms (7.6%): 19 ischemic, 11 hemorrhagic, and 8 others. (ajnr.org)

The resuscitation after an HS causes a reperfusion or reoxygenation insult [ 2 - 4 ], gut injury, and multiple organ dysfunctions [ 5 , 6 ]. (medsci.org)

The concern is that aggressive resuscitation may elevate the blood pressure and increase hemorrhage through an uncontrolled injury site. (medscape.com)

These devices can be threaded into the blocked artery for removal of the clot or thrombus in a procedure called mechanical thrombectomy. (adam.com)

If no significant injuries requiring surgery are present, observation or expectant management may proceed. (medscape.com)

The purpose of the study was to evaluate the effect of delta-9-tetrahydrocannabinol (THC), the major psychoactive constituent of marijuana, on ischemic neuronal injury. (erowid.org)
THC at either dose did not significantly reduce ischemic neuronal damage in the hippocampus. (erowid.org)

Thus, some authors have proposed a "no-zone" management approach to penetrating neck trauma, treating the neck as a whole and choosing to explore or image each patient by the presentation and symptoms, not exclusively by the anatomic location of the injury. (medscape.com)

An MRI confirmed diffusion and FLAIR positive ischemic strokes within the deep periventricular white matter compatible with a "watershed" distribution of injury (Figure 3). (nspc.com)

However, it is not known whether resuscitation after a [ 10 - 12 ] HS can cause cerebral injury and concomitant neurological dysfunction, and its potential mechanisms. (medsci.org)

Evaluate and monitor the neurologic status of the patient with consideration for spinal cord injury, as well as vascular trauma with cerebral circulatory compromise. (medscape.com)
Blunt cerebrovascular injury (BCVI) is found in 1-2.7% of all blunt trauma when appropriate screening criteria are employed. (openneuroimagingjournal.com)

Thus, we hypothesized that the endogenous mannose-binding lectin (MBL)/ficolin-associated protein-1 (MAP-1) that inhibits complement activation in vitro also could be an in vivo regulator by attenuating myocardial schema/reperfusion injury and thrombogenesis when used at pharmacological doses in wild-type mice.

Thus, we hypothesized that the endogenous mannose-binding lectin (MBL)/ficolin-associated protein-1 (MAP-1) that inhibits complement activation in vitro also could be an in vivo regulator by attenuating myocardial schema/reperfusion injury and thrombogenesis when used at pharmacological doses in wild-type mice.METHODS AND RESULTS: In 2 mouse models, MAP-1 preserves cardiac function, decreases infarct size, decreases C3 deposition, inhibits MBL deposition, and prevents thrombogenesis.

Angiography of the right ICA showed a severely stenotic but intact lumen of the artery, and we decided to perform endovascular carotid artery stenting. (bmj.com)

They also point to the efficacy of N-acetylcysteine in reducing the deleterious effects of inflammation-associated perinatal injuries by a previously undescribed mechanism, i.e. the inhibition of innate immune cell migration across the choroid plexuses, without interfering with the systemic inflammatory response to infection. (biomedcentral.com)

This prevents plaque, a waxy deposit, from building up in the carotid arteries. (medlineplus.gov)
Carotid plaque. (medscape.com)

With the advance of noninvasive imaging modalities, most notably CT angiography, came a paradigm shift in the management of these injuries. (medscape.com)
