Brachial Artery Vasospasm Caused by Cervical Dorsal Root Ganglion Degeneration After Subarachnoid Hemorrhage: An Experimental Study

Kayaci, Salim; Cakir, Tayfun; Aydin, Mehmet Dumlu; Kanat, Ayhan; Omeroglu, Muhammed; Levent, Akin; Demirci, Elif (Elsevier Science Inc, 2019)

PURPOSE: Subarachnoid hemorrhage (SAH) may lead to vasospasm in various vessels. the cervical nerves have a vasodilatory effect on the upper extremity arteries. the aim of this study was to investigate if there is a ...

A New Determinant of Poor Outcome After Spontaneous Subarachnoid Hemorrhage: Blood pH and the Disruption of Glossopharyngeal Nerve-Carotid Body Network: First Experimental Study

Kanat, Ayhan; Aydin, M. Dumlu; Bayram, Ednan; Kazdal, Hizir; Aydin, Nazan; Omeroglu, Muhammet; Calik, Muhammet (Elsevier Science Inc, 2017)

OBJECTIVE: the chemoreceptor network, consisting of the glossopharyngeal nerve and carotid body (GPN-CB), is essential for the regulation of blood pH. Its ischemic insults after subarachnoid hemorrhage (SAH), which may ...

New Evidence for Causal Central Mechanism of Hyperglycemia in Subarachnoid Hemorrhage Secondary to Ischemic Degenerative Disruption of Circuitry Among Insular Cortex, Nodose Ganglion, and Pancreas: Experimental Study

Aydin, Mehmet Dumlu; Kanat, Ayhan; Aydin, Nazan; Kantarci, Abdulmecit; Ayvaz, Muhammet Ali; Rakici, Halil; Demirci, Elif (Elsevier Science Inc, 2017)

INTRODUCTION: Although hyperglycemia is a serious complication of subarachnoid hemorrhage, its pathophysiologic mechanism based on neural circuitry has not been known. - MATERIALS AND METHODS: Twenty-five rabbits were ...

Unraveling of the Effect of Nodose Ganglion Degeneration on the Coronary Artery Vasospasm After Subarachnoid Hemorrhage: An Experimental Study

Yolas, Coskun; Kanat, Ayhan; Aydin, Mehmet Dumlu; Altas, Ender; Kanat, Ilyas Ferit; Kazdal, Hizir; Gursan, Nesrin (Elsevier Science Inc, 2016)

BACKGROUND: Cardiac arrest is a major life-threatening complication of subarachnoid hemorrhage (SAH). Although medullary cardiocirculatuar center injury and central sympathetic overactivity have been suspected of initiating ...

Rational Roots of Sympathetic Overactivity by Neurogenic Pulmonary Edema Modeling Arising from Sympathyco-Vagal Imbalance in Subarachnoid Hemorrhage: An Experimental Study

Onen, Mehmet Resid; Yilmaz, Ilhan; Ramazanoglu, Leyla; Tanriverdi, Osman; Aydin, Mehmet Dumlu; Kanat, Ayhan; Sipal, Sare (Elsevier Science Inc, 2016)

BACKGROUND: Autonomous innervations of the lungs are maintained by cervical sympathetic and vagal nerves. Sympathetic overactivity-induced neurogenic pulmonary edema (NPE) is known as a serious complication of subarachnoid ...

Uncovering a New Cause of Obstructive Hydrocephalus Following Subarachnoid Hemorrhage: Choroidal Artery Vasospasm-Related Ependymal Cell Degeneration and Aqueductal Stenosis-First Experimental Study

Yolas, Coskun; Ozdemir, Nuriye Guzin; Kanat, Ayhan; Aydin, Mehmet Dumlu; Keles, Papatya; Kepoglu, Umit; Gundogdu, Cemal (Elsevier Science Inc, 2016)

BACKGROUND: Hydrocephalus is a serious complication of subarachnoid hemorrhage (SAH). Obstruction of the cerebral aqueduct may cause hydrocephalus after SAH. Although various etiologic theories have been put forward, ...
