TY - JOUR. T1 - Pharmacological properties of serotonin receptor subtypes mediating contraction of bovine inferior alveolar arteries. AU - ODonohue, H. A.. AU - Abel, P. W.. AU - Bockman, C. S.. PY - 2004/3. Y1 - 2004/3. N2 - Objective: To characterise the 5-hydroxytryptamine (5-HT) receptor subtypes mediating contraction of the inferior alveolar artery. Additionally, to determine the role of cyclooxygenase products, nitric oxide, endothelium, monoamine oxidase and 5-HT uptake in modulating contraction of inferior alveolar arteries to 5-HT. Methods: Contractile responses to 5-HT were examined in vitro using ring segments of bovine inferior alveolar arteries. Affinity constants (KBs) of subtype-selective 5-HT receptor antagonists were determined to characterise the 5-HT receptor-subtypes causing contraction of inferior alveolar arteries. Results: In 100nM ketanserin or 30nM spiperone, 5-HT caused a biphasic contraction best-fit by a two-site curve model, where one site was antagonist-sensitive ...
Definition of anterior superior alveolar arteries. Provided by Stedmans medical dictionary and Drugs.com. Includes medical terms and definitions.
The infraorbital artery is an artery in the head that branches off the maxillary artery, emerging through the infraorbital foramen, just under the orbit of the eye. The infraorbital artery appears, from its direction, to be the continuation of the trunk of the maxillary artery, but often arises in conjunction with the posterior superior alveolar artery. It runs along the infraorbital groove and canal with the infraorbital nerve, and emerges on the face through the infraorbital foramen, beneath the infraorbital head of the levator labii superioris muscle. While in the canal, it gives off (a) orbital branches which assist in supplying the inferior rectus and inferior oblique and the lacrimal sac, and (b) anterior superior alveolar arteries - branches which descend through the anterior alveolar canals to supply the upper incisor and canine teeth and the mucous membrane of the maxillary sinus. On the face, some branches pass upward to the medial angle of the orbit and the lacrimal sac, anastomosing ...

The complication rates of carotid artery stenting (CAS) vary from 3.0% to 4.4%, and most commonly include ischemic stroke, intracranial hemorrhage, or groin complications. We present the rare complication of a patient who underwent CAS for a symptomatic 90% left internal carotid artery stenosis and developed an expanding cervical hematoma after the procedure with imminent respiratory compromise. After intubation, an arteriogram revealed perforation of the external carotid artery trunk, proximal to the origin of the internal maxillary artery. The artery was subsequently embolized and the hematoma resolved without further intervention. We present a potential catastrophic complication and suggest potential causes and treatment options available.. ...
Materials and methods Cone beam CT (CBCT) was performed using a flat panel detector angiography system. Datasets were reconstructed from 620 projection images acquired over a 200° arc (rotation time 20.7 s) at 80 kVp and a total of 260 mAs. To maximize spatial resolution, projection images were obtained using a small detector format (22 cm) and reconstructions were performed without pixel binning.. A contrast injection protocol was optimized in a porcine model for balance between stent visualization host vessel opacification. Three different intracranial stents were deployed in the internal maxillary arteries of two Yorkshire swine. Selective CBCT angiography was performed at contrast concentrations between 10 and 30% (Iopamidol 51%, by volume in normal saline) and flow rates between 0.5 and 3.5 ml/s. The CBCT datasets were reviewed and the optimal combination of parameters was used for clinical testing.. The clinical study was approved by our institutional review board. 57 CBCT examinations of ...

The effects of 5-hydroxytryptamine (5-HT, serotonin) on cerebral blood flow were evaluated in unanesthetized goats under normal conditions and after selective blockade of 5-HT receptors or impairment of the sympathetic activity present in cerebral vessels. Small doses of 5-HT (0.1-9 micrograms) injected directly into the internal maxillary artery produced dose-dependent reductions in cerebral blood flow, a decrease of 49.8 +/- 2.5% (S.E.M.) occurring with the highest dose. Slow i.v. infusion of lysergic acid diethylamide (0.2-0.4 micrograms/kg/min), methysergide or cyproheptadine (2-5 micrograms/kg/min) partially abolished the cerebral vasoconstriction produced by 5-HT. Both phentolamine and reserpine also diminished the vasoconstriction induced by 5-HT. Goats in which the superior cervical sympathetic ganglion had been removed 7 to 20 days before the experiment showed a significant decrease in the cerebral vasoconstriction elicited by 5-HT. These results indicate that 5-HT produces marked ...

We have previously shown that in situ beta radiation prevents recanalization after coil embolization.1 This process seems to occur soon after coil implantation into canine arteries, and if recanalization is inhibited for 3 weeks, arteries remain occluded at 3 months.1 We thus limited the period of observation to 4 weeks for most animals of the present experiments. The coil arterial occlusion model is simple and reliable. Multiple devices (up to 6) can be compared within the same animal. Coil occlusions routinely recanalize, and, as such, this model is well suited to evaluate coil modification strategies designed to inhibit recanalization. This model is not subject to variations of residual flow found after embolization at the neck of aneurysmal models, which can confuse follow-up results.. The present study emphasizes the strength of the recanalization process after coil occlusion of canine arteries, which occurred routinely regardless of coil caliber, coil length, resulting packing density, and ...

With that being said, last week I had the 2nd most personal scare of my life on Sunday morning, about 4am (2nd only to my sons accident a couple years ago,)18 days post surgery. Apparently, I suffered a side affect that only affects approx 1 in 800 patients so they dont specifically go over this risk in the 5 sheets of risks you sign off on before surgery. I woke with a ruptured aneurysm of my Maxillary Artery (this runs from the back wall of your sinus cavity to your Maxilla- explains why blood comes from nose and mouth)... I am not telling this to scare those who might be in the process of having this surgery but to let you know if it happens to you, which it most likely will not, it will be o.k. FIRST: call 911 - apply pressure to the front of your mouth with a towel and your nose (pinch the very top of your nose.) I woke with blood gushing out my nose and 2 seconds later it was gushing out of my mouth as well.... not really knowing where the bleeding was coming from was frightening. Husband ...
What treatments were available for skin wounds, and what were the challenges and controversies surrounding them? Did early modern surgeons discuss pain control, or is this, as some historians have claimed, a modern concern? And what can all of this tell us about the history of skin? 13 Many of the surgical cases in mid- to late eighteenth-century London came to St Bartholomews Hospital, one of the English capitals seven teaching hospitals. Patients there often came under the care of Percivall Pott (1714-1788), considered by his peers to be the best practical surgeon of his day. Case three in the book involved an Oxfordshire man who presented himself at the hospital with three diseased lymphatic glands of the neck, each the size of a large plum. Sir Charles Blicke, a surgeon, removed the diseased gland and the external maxillary artery was unavoidably divided. The patients wound was sutured (with one suture) and closed with sticking plasters. 64 In fact suturing more often involved dead ...

Woodruff[who?] in 1949 discovered plexus of prominent blood vessels lying inferior to posterior end of inferior turbinate. Woodruffs area is present under the posterior end of inferior turbinate on the lateral nasal wall which is also called nasopharyngeal plexus. The sphenopalatine and posterior pharyngeal arteries anastamoses at the posterior end of inferior turbinate. Sphenopalatine artery enter the nasal cavity through the sphenopatine foramen located on lateral nasal wall within superior meatus usually between the middle turbinate and posterior horizontal end of the lamella of the superior turbinate. Generally this is just about the posterior end of the horizontal lamella of the middle turbinate and just posterior to the ethmoidal crest of the perpendicular plate of the palatine bone. Posterior epistaxis occur primarily in old adult. Only about 5-10% of bleeding which occurs is from woodruffs area from the branches of internal maxillary artery including: Posterior nasal, Spheno-palatine ...

A 15-year old Selle Francais gelding was presented to the equine referral hospital for treatment of a left guttural pouch mycosis previously diagnosed. After induction the horse was shortly hoisted by all four feet, moved on a padded surgical table and positioned in right lateral recumbency. In order to reduce the risk of bleeding during surgical manipulation of the carotid and maxillary arteries, a mean arterial pressure between 60 and 70 mmHg was targeted. After surgery, the horse was moved in a padded recovery box keeping the same lateral recumbency. Four unsuccessful attempts were performed, with the horse always returning to sternal recumbency keeping the left hind limb up. At the fifth attempt, performed 120 minutes after the end of the general anesthesia, the horse stood up correctly but moderate ataxia and absence of weight bearing on the left hind limb were shown. Both the stifle and the fetlock joint were held in a flexed position and could not be extended properly in order to set the foot on
The mandibular nerve is one of three branches of the trigeminal nerve, and the only one having motor innervation. One branch of it, the inferior alveolar nerve as well as the inferior alveolar artery enter the foramen traveling through the body in the mandibular canal and exit at the mental foramen on the anterior mandible at which point the nerve is known as the mental nerve. These nerves provide sensory innervation to the lower teeth, as well as the lower lip and some skin on the lower face. ...

The researchers designed a simple, randomized, blinded clinical trial to compare the effectiveness of the infraorbital technique in upper premolar anesthesia to that of the MSA technique, using 2% lidocaine with epinephrine 1:80,000. This study was carried out on 30 volunteers, 22 women and 8 men between the ages of 18 and 44 years, in whom a total of 120 teeth were evaluated with the use of an electronic pulp tester (Analytic Technology, Redmond, Washington). Also, 600 vitality tests were performed-six tests per tooth every 5, 10, 15, 20, 30, and 40 minutes. The present study was carried out at the University of Cartagena in Cartegena, Colombia.. The researchers evaluated the degree of successful pulpal anesthesia, pain at the puncture, soft-tissue anesthesia, perception of the patients comfort before this anesthesia, the time of onset, and the duration of the anesthetic effect. Participants were excluded based on the following criteria: patients with premolars without pulpal vitality or with ...
The maxillary nerve is one of the three large branches of the trigeminal sensory nerve. This includes the ophthalmic, maxillary, and mandibular divisions.

This exhibit depicts the right middle meningeal artery within the lateral skull. The middle meningeal artery is a terminal branch of the external carotid artery which enters the skull through the foramen spinosum. Upon entering the skull, it supplies the dura mater and calvaria. Its branches can be seen extending beneath the frontal, temporal, sphenoid, and parietal bones of the skull.
ASA Nerve Block Technique What it numbs: The anterior superior alveolar nerve block (ASA) also known as the infraorbital nerve block. Provides pulpal anesthesia to the maxillary anterior teeth on the side injected, the central and lateral incisors, and canine. In addition to the buccal soft tissue and bone the skin of the lower eye lid, the lateral side of the nose and the upper lip may all be anesthetized.. Needle:. A 27 - gauge short for children or small adults or a 25-gauge long needle is recommended. Positioning:. Patient position is supine or semi supine. For the right ASA nerve block and right handed operator, sit at a 10 oclock position facing the patient. For the left ASA nerve block and right handed operator, sit at a 8 or 9 oclock position facing the patient. Landmarks:. The landmarks are the infraorbital foramen, the mucobuccal fold , the apex of the canine and the canine eminence. Target area:. The target area and injection site is located at the height of the buccal fold adjacent ...
The blood supply of the face is through branches of the facial artery (Figure 1-2). After arising from the external carotid artery in the neck, the facial artery passes deep to the submandibular gland and crosses the mandible in front of the attachment of the masseter muscle. It takes a tortuous course across the face and travels up to the medial angle of the eye, where it anastomoses with branches of the ophthalmic artery. It gives labial branches to the lips, of which the superior labial artery enters ...
ISO 21439:2009 specifies methods for the determination of absorbed-dose distributions in water or tissue that are required prior to initiating procedures for the application of beta radiation in ophthalmic tumour and intravascular brachytherapy]. Recommendations are given for beta-radiation source calibration, dosemetry measurements, dose calculation, dosemetric quality assurance, as well as for beta-radiation brachytherapy treatment planning. Guidance is also given for estimating the uncertainty of the absorbed dose to water. ISO 21439:2009 is applicable to "sealed" radioactive sources, such as plane and concave surface sources, source trains of single seeds, line sources, shell and volume sources, for which only the beta radiation emitted is of therapeutic relevance.. The standardization of procedures in clinical dosemetry described in ISO 21439:2009 serves as a basis for the reliable application of beta-radiation brachytherapy. The specific dosemetric methods described in ISO 21439:2009 apply ...

The extent of resection by surgery affects survival time in GBM patients (5,6). A better prognosis might therefor be predicted for right temporal lobe localized GBM, since total removal can be carried out.. The present case was initially diagnosed as meningioma, because the tumor stain was clearly seen from the middle meningeal artery but not from the internal carotid artery. Only a few case reports of such GBMs have been described (7,8). The timing of surgical treatment may easily be delayed if the lesion is misdiagnosed as a meningioma, and may be of concern for the prognosis of GBM patients.. Cyst formation is known to occur as an adverse event of carmustine wafer implantation for malignant gliomas (9), and there have been several reports of space-occupying cysts in the cavity, which required additional surgical treatment (10-13). Yoshida et al reported that adverse events associated with implantation of carmustine wafers tend to occur in the repeated surgery for the malignant gliomas (11). ...
