We describe a cuff-type electrode specifically designed for recording from, and electrical stimulation of, cut nerves in acute experiments on small animals. Unlike existing designs of cuff electrodes, it is simple to manufacture, inexpensive and takes little time to implant. The electrode was tested on the hypoglossal, phrenic, recurrent laryngeal, and superior laryngeal nerves in anesthetized ...

INTRODUCTION The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD) in patients with or without a variant hepatic artery arising from superior mesenteric artery. MATERIAL AND METHODS We reviewed 151 patients with periampullary tumoral pathology. All patie...

Many variations exist in the branching pattern of the aortic arch. One variation exists in which there is a common origin of the carotid arteries, known as a bicarotid trunk, coexisting with a retroesophageal right subclavian artery. This anomaly is associated with a right non-recurrent laryngeal nerve. Aortic arch anomalies are clinically applicable to the fields of anatomy, radiology, general...

Introduction Recurrent laryngeal nerve injury caused by cardiovascular disease is a rare condition, and often it is the only prominent sign of an imminent break of an aortic artery aneurysm. Objective To report left laryngeal paralysis caused by a great aortic arch aneurysm and to highlight the importance of an otorhinolaryngologic evaluation along with a thoracic radiologic study. Resumed Repo...

Introduction The study examined the effects of cuff inflation of a ProSeal Laryngeal Mask Airway on the carotid bulb during sevoflurane induction in pediatric population. The hemodynamic parameters measured were: systolic and diastolic pressure, heart rate and sovraortic flow trough measurements of bilateral carotid cross sectional area, velocity of blood flow, resistance index, flow accelerati...

Instruction: Measurement of brachial artery diameter variation by ultrasound methods has commonly been used to test the endothelial function. It is known that the artery diameter is increased by flow stimulation. Therefore in the present study, the effect of external obstruction, as flow stimulation, on the radial strain of the brachial artery was assessed. Also the biomechanical behavior of...

Effects of perineural capsaicin (CAPS) treatment on compound action potentials of the superior laryngeal nerve (SLN) afferents were studied in 6 sevoflurane-anesthetized dogs. Perineural CAPS (100 microg/ml) to the bilateral SLNs reduced (P<0.01) the peak and integral amplitudes of the C-wave of the compound action potential. By contrast, the perineural CAPS had no effect on the A-wave componen...

Isolated superior cerebellar artery infarction is rare, and the mechanism is often not readily apparent. We describe a patient with an isolated superior cerebellar artery infarction resulting from an ipsilateral vertebral artery dissection. Angiography demonstrated intraluminal clot in the superior cerebellar artery, suggesting artery-to-artery embolus as a mechanism of this uncommon stroke syn...
