Acute basilar artery thrombosis is associated with a poor prognosis. However, the advent of high-quality, reliable, and noninvasive technology (eg, magnetic resonance imaging [MRI]) has made its diagnosis possible even in subjects with mild symptoms (see the image below).

TY - JOUR. T1 - Endothelium-independent contractions to jvg-monomethyl-l-arginine in canine basilar artery. AU - Katušić, Zvonimir S.. PY - 1991/11. Y1 - 1991/11. N2 - Background and Purpose: NG-substituted analogues of L-arginine are potent and selective inhibitors of nitric oxide synthase(s). The present study was designed to determine the effects of these analogues on the vascular smooth muscle of isolated canine basilar arteries. Methods: Basilar artery rings without endothelium were suspended for isometric tension recording in Krebs-Ringer bicarbonate solution bubbled with 94% O2-6% CO2 (temperature=37°C, pH=7.4). A radioimmunoassay technique was used to determine the levels of guanosine 3,5-cyclic monophosphate (cyclic GMP). Results: NG-Monomethyl-L-arginine (L-NMMA) caused concentration-dependent contractions, whereas the D-enantiomer and NG-nitro-L-arginine did not. Contractions to L-NMMA were reduced in the presence of L-arginine but not in the presence of D-arginine. Superoxide ...
TY - JOUR. T1 - Role of ATP-sensitive K+ channels in CGRP-induced dilatation of basilar artery in vivo. AU - Kitazono, Takanari. AU - Heistad, D. D.. AU - Faraci, F. M.. PY - 1993/9/22. Y1 - 1993/9/22. N2 - Stimulation of adenylate cyclase appears to activate ATP-sensitive K+ channels in the basilar artery. We tested the hypothesis that calcitonin gene-related peptide (CGRP), which increases intracellular adenosine 3,5- cyclic monophosphate (cAMP) levels, activates ATP-sensitive K+ channels and thereby causes vasodilatation. Using a cranial window in anesthetized rats, we examined responses of the basilar artery to CGRP in vivo. We also examined responses of the artery to another vasoactive peptide, vasoactive intestinal peptide (VIP). Topical application of CGRP (10-11 to 10-8 M) increased diameter of the basilar artery. Responses of the basilar artery to CGRP were almost abolished by a CGRP1 receptor antagonist, CGRP-(8-37). Vasodilatation in response to VIP was much smaller than that ...
Basilar artery stenosis treatment - What is the treatment and prognosis for someone with a combination of carotid occlusion/stenosis and occlusion/stenosis of the basilar artery? Depends. Artery disease in the neck vessels (carotid/basilar) is associated with risk for stroke. Your doc, vascular provider can best assess all the associated factors and give you a risk assessment. Treatments vary from medical management, nicotine cessation, stenting, surgery and combinations of them all.
Rationale: Recently our study group reported the results of the Basilar Artery International Cooperation Study (BASICS), a prospective registry of patients with an acute symptomatic basilar artery occlusion (BAO). Our observations in the BASICS registry underscore that we continue to lack a proven treatment modality for patients with an acute BAO and that current clinical practice varies widely. Furthermore, the often-held assumption that intra-arterial thrombolysis (IAT) is superior to intravenous thrombolysis (IVT) in patients with an acute symptomatic BAO is challenged by our data. The BASICS registry was observational and has all the limitations of a non-randomised study. Interpretation of results is hampered by the lack of a standard treatment protocol for all patients who entered the study.. Objective: Evaluate the efficacy and safety of IAT in addition to best medical management (BMM) in patients with basilar artery occlusion.. Study design: Randomised, multi-centre, open label, ...
The trigeminal artery is one of the embryonic anastomoses between the carotid and the vertebrobasilar systems. These anastomoses arise early during the 5 to 6 mm stage of embryonic development. The embryonic hindbrain is supplied by a pair of longitudinal neural arteries, which in turn are supplied by the carotid system through these primitive anastomoses. As the paired longitudinal neural arteries fuse to form the basilar artery, these vessels regress, typically at the 14 mm embryo stage [1, 2]. Persistence of any of these anastomoses may occur, and the persistent trigeminal artery [PTA] is the most common, accounting for 85% of cases [1].. The PTA connects the cavernous segment of the internal carotid artery and the basilar artery. It has a reported incidence of 0.2%, although actual incidence may be higher due to undiagnosed cases [1]. PTA is mostly asymptomatic, and patients usually undergo imaging for other clinical concerns. In some cases, patients present with symptoms of cerebrovascular ...

The amplification was antagonized by methiothepin, but not by ketanserin, and it could be mimicked by methysergide.

The basilar artery (/ˈbæz.ɪ.lər/)[1][2] is one of the arteries that supplies the brain with oxygen-rich blood. The two vertebral arteries and the basilar artery are sometimes together called the vertebrobasilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of Willis from the internal carotid arteries.[3] ...

The pontine arteries are a number of small vessels which come off at right angles from either side of the basilar artery and supply the pons and adjacent parts of the brain. Branches of basilar artery - The basilar artery extends from the lower to the upper border of the pons. It lies in the median groove under the cover of arachnoid membrane.It divides into following branches on either side- Pontine artery Anterior inferior cerebellar artery (AICA) Superior Cerebellar artery (SCA) Posterior cerebral artery Internal auditory artery Perforators - The small branches of the basilar artery are also known as perforators and this peroforating arteries can be classified into three subgroups : (i) rostral (mesencephalic perforating arteries, distal to the SCA); (ii) middle (pontine perforating arteries, between the SCA and AICA); (iii) caudal (proximal to the AICA). There are between two and five rostral BA perforators, which have an average diameter of 250 μm; the caudal perforators vary in diameter ...
Methods We present the case of a 49-year-old female with a history of smoking, who was diagnosed with a symptomatic, large vertebrobasilar junction (VBJ) aneurysm. Initially thought to be a proximal basilar dilatation, the aneurysm was later found to arise from an obscured and distended basilar fenestration. The small caliber fenestration limbs were the only access to the distal basilar artery, but stretched laterally and concealed by the aneurysm fundus. ...
Direct CCFs are included among type A fistulas according to Barrows classification. Etiologically, most dissecting CCFs are traumatic, but less commonly they may be spontaneous. Spontaneous direct CCFs are usually caused by rupture of an intracavernous carotid aneurysm, and aneurysmal CCFs account for about 20% of direct CCFs (8).. Spontaneous or traumatic CCF from the persistent trigeminal artery to the cavernous sinus and its endovascular treatment has rarely been reported (2-7). To the best of our knowledge, however, CCF caused by a ruptured aneurysm of the anomalous cerebellar artery has not been reported.. The cerebellar artery originating from the internal carotid artery was first reported by Teal et al (9). The level of the internal carotid artery from which these vessels took origin led to the conclusion that they were persistent trigeminal artery variants (1, 11). Unlike the usual persistent trigeminal artery that has a direct communication with the basilar artery, the persistent ...

Not a section from the instruction manual of my vacuum cleaner. But models of the church as described by Peter Neilson in his book Church on the Move. He suggests that most of us work on the suction model of church - hoping to draw people in through the doors. The slipstream model, by contrast, is about believing that God is at work out in the community and that a different kind of church should form in the slipstream of that movement of grace …. Meanwhile, Ive also been reading that cheery book Turning the Tide - Report of the 2002 Scottish Census - which charts the inexorable decline of churches in Scotland. Canute tried to stop the tide coming in - my job is to stop it going out.

Patients admitted in severe neurological condition, with reduced consciousness and already permanent brain tissue damage, pose a dilemma to emergency medical personnel who need to weigh different therapeutic options in the face of uncertain long-term prognosis. Thrombolysis might save the life, but what kind of quality of life will follow? Vertebrobasilar cerebrovascular disease may provide the most extreme physical deprivation while leaving the faculty for contemplation as good as intact. The recent analysis of the delayed-phase outcome after BAO thrombolysis suggests that on the long term, survivors who initially reach the worst functional outcome (modified Rankin Scale 5) will subsequently either decease or improve.10 Eventually, more than half of those who recanalize will acquire functional independence. Furthermore, the perceived quality of life of the survivors seems at least fair, correlating with the level of functional independence.10. What are the risks of recanalization therapy? The ...

Treatment of acute basilar artery occlusion remains clinically challenging. In this preliminary study of diffusion-perfusion MRI changes in patients treated with intra-arterial thrombolysis and studied serially with multimodal MRI, we found that diffusion-perfusion mismatch can be visualized clearly in the posterior circulation, including the brain stem, and can be seen in some patients well beyond 6 hours from symptom onset. Moreover, we were able to demonstrate improvement of this mismatch region after basilar artery recanalization with intra-arterial thrombolytic therapy. This improvement may represent therapeutic salvage of the mismatch region; however, a controlled study is required to confirm this.. Several prior reports have begun to assess the role of advanced MRI techniques in acute posterior circulation stroke.10,11 Du Mesnil de Rochement and colleagues10 studied 4 patients with acute basilar artery occlusions with DWI and MR angiography sequences. They found variable patterns of DWI ...
Pseudoaneurysms, or false aneurysms, are differentiated from true aneurysms by the layers of the artery involved. Pseudoaneurysms are the result of the rupture of all three layers of the artery: the tunica intima, media, and adventitia. The aneurysm is contained by an organized hematoma or neighboring connective tissue. With true aneurysms, the outermost layer, the adventitia, remains intact.. As a result of its secure location, injury to the basilar artery is rare.1 Only 10% of traumatic aneurysms in the brain occur in the posterior circulation. As was seen in this case, the majority of basilar artery aneurysms are associated with skull base fractures. In addition, the connective tissue surrounding the basilar artery is usually unable to contain the aneurysm, making it improbable that a patient would survive a traumatic aneurysm in the posterior circulation.2 Rapid treatment is imperative because of the high morbidity and mortality associated with basilar artery pseudoaneurysms. ...
Cerebral vasospasm is one of the major complications of subarachnoid hemorrhage (SAH). However, its pathogenesis still remains to be elucidated, and effective therapeutic strategies are yet to be established. We have reported, in the previous meeting, that thrombin plays a key role in up-regulation of the proteinase-activated receptor-1 (PAR1) expression and development of the vasospastic response to thrombin in the basilar artery of rabbit double hemorrhage-SAH model. In the present study, we demonstrated a new strategy to prevent the development of such vasospastic response using selective PAR1 antagonists. The rabbits received two injections of autologous blood into the cisterna magna on days 0 and 2. The contractile responses were examined on day 7 using basilar artery ring preparations, in the absence of endothelial cells. Thrombin and PAR1 activating peptide (PAR1-AP) slightly contracted the control artery only at high concentrations (10 U/ml thrombin or 100 μM PAR-1AP). In SAH, the ...
A 28-year-old Pakistani man was admitted with unresolved severe headaches for the past four weeks. Magnetic resonance (MR) imaging and MR angiography showed an enhancing mass in the sphenoid sinus, bilateral cerebellar infarcts and aneurysmal dilatation of the basilar artery. The differential diagnosis included fungal infection versus neoplastic lesion. The scrappings taken through the endoscope from the sphenoid sinus were initially negative for fungal infection. However, the second biopsy, done after putting him on antifungal, itraconazole 200 mg twice daily, revealed the presence of a fungal infection (aspergillosis). MR imaging revealed extension of the fungal infection from the sphenoid sinus into the clivus, and then intracranially. Imaging also revealed aneurysmal dilatation of the basilar artery and infarctions in the cerebellum and subarachnoid haemorrhage. Despite aggressive antifungal treatment, the Patient died after 29 days. This case report describes the probable mechanism of fungal
Subclavian steal is a relatively common vascular phenomenon usually caused by atherosclerotic disease. While symptoms are rare, arm claudication of the ipsilateral limb is most common, with paroxysmal symptoms of vertebrobasilar insufficiency (often exercise induced) being relatively uncommon. Here we present a case of brachial artery embolism during mechanical thrombectomy for basilar artery thrombosis, secondary to subclavian steal phenomenon. This atypical and potentially irreversible complication should be considered in patients with acute ischemic stroke undergoing neurointerventional management when subclavian steal is discovered angiographically. ...
The role of the endothelium was examined in the response to aggregating platelets in cerebral arteries from normal and hypercholesterolemic animals. Male Yorkshire pigs were fed either a normal diet or a 2% high-cholesterol diet for 10 weeks. Endothelium-dependent responses were examined in vitro. In rings of basilar arteries from control animals aggregating platelets caused endothelium-dependent relaxations, which were significantly inhibited by apyrase, an adenosine diphosphatase and triphosphatase, but were augmented by methiothepin, a combined S1- and S2-serotonergic blocker. In quiescent rings platelets induced contractions that were inhibited by the presence of the endothelium; these contractions were significantly inhibited by methiothepin, but not by ketanserin (an S2-serotonergic blocker) or dazoxiben (a thromboxane-synthetase blocker) in the presence or absence of SQ29548 (a thromboxane-receptor blocker). Adenosine diphosphate but not serotonin caused endothelium-dependent relaxations. ...

The internal carotid arteries branch off the common carotid arteries in the neck just below the mandible. They give off no branches until meeting with the communicating branches of the basilar artery. The basilar artery is formed by the two vertebral arteries which arrive at the posterior of the brain via the vertebral column. Together the basilar and internal carotid arteries form the Circle of Willis, the primary vasular structure supplying blood to the brain. Blood from the internal carotids primarily goes to the frontal and temporal lobes. ...
We compared traditional steady-state experiments with nonsteady-state experiments in defining the vasodilating potency of isoflurane in isolated cerebral vessels. The effects of volatile anesthetics on isolated arterial vessel wall tension are typically examined by means of steady-state methodology. This requires the prolonged administration of the agent under study until a stable wall tension is achieved. An alternative, non-steady-state approach to such experiments is proposed as an adjunct technique to help simplify and in some cases evaluate more fully vascular response. Cylindrical segments of the rabbit basilar artery were placed into a perfused tissue bath, stretched to a resting tension of approximately 2000 dynes and then constricted with 30 nM K+. Thirty minutes later, 2.0 MAC of isoflurane was introduced into the fluid reservoir supplying the chamber. This administration was continued for 10 min, at which time isoflurane was discontinued and vessel tension was monitored for another 10 ...

Until the development of the SuperBypass instrument series, our standard platform tipped forceps occasionally disturbed the flow of the procedures because the tip lacked a slip-resistant surface. Despite our standard forceps acceptable performance most of the time, many times I was forced to adjust the forceps grip on either the suture or the needle as I lost control of it.. By extending the platform length to 7mm and 10mm and changing the metallic chemistry of the tips we have created instruments with superior gripping ability. The SuperBypass forceps provides the ultimate control in procedures where manipulation of sutures within narrow and deep areas is also limited to single direction movement. We can now perform P2 bypass and basilar artery anastomosis using the long, straight SuperBypass instruments, while the bayonetted version further moderates the challenge of suturing in tight quarters under the surgical microscope..
