3D angiography. Clinical interest. First applications in interventional neuroradiology. (1/642)

3D angiography is a true technical revolution that allows improvement in the quality and safety of diagnostic and endovascular treatment procedures. 3D angiography images are obtained by reconstruction of a rotational angiography acquisition done on a C-arm (GE Medical Systems) spinning at 40 degrees per second. The carotid or vertebral selective injection of a total of 15 ml of non-ionic contrast media at 3 ml/sec over 5 seconds allows the selection of the "arterial phase". Four hundred sixty 3D angiographic studies were performed from December 1996 to September 1998 on 260 patients and have been analyzed in MIP (Maximum Intensity Projection) and SSD (Shaded Surface Display) views. The exploration of intracranial aneurysms is simplified and only requires, for each vascular axis, a biplane PA and Lateral run followed by a single rotational angiography run. The 3D angiography image is available on the workstation's screen (Advantage Workstation 3.1, GE Medical Systems) in less than 10 minutes after the acquisition of the rotational run. It therefore allows one to analyze, during the intervention, the aneurysm's angioarchitecture, in particular the neck, and select the best therapeutic technique. When endovascular treatment is the best indication, 3D angiography allows one to define the optimal angle of view and accurately select the microcoils dimensions. 3D angiography replaces the multiple oblique views that used to be required to analyze the complex aneurysms and therefore allows a reduction of the total contrast medium quantity, the patient X-ray dose and the length of the intervention time which is a safety factor. Also, in particular for complex cases, it brings additional elements complementing the results of standard 2D DSA and rotational angiograms. In the cervical vascular pathology, 3D angiography allows for a better assessment of the stenosis level and of dissection lesions. Our current research activities focus on the matching without stereotactic frame between 3D X-ray angiography and volumetric MR acquisition, which should allow us to improve the treatment of intracerebral arterio-venous malformations (AVMs).  (+info)

Rupture mechanism of a thrombosed slow-growing giant aneurysm of the vertebral artery--case report. (2/642)

A 76-year-old male developed left hemiparesis in July 1991. The diagnosis was thrombosed giant vertebral artery aneurysm. He showed progressive symptoms and signs of brainstem compression, but refused surgery and was followed up without treatment. He died of rupture of the aneurysm and underwent autopsy in March 1995. Histological examination of the aneurysm revealed fresh clot in the aneurysmal lumen, old thrombus surrounding the aneurysmal lumen, and more recent hemorrhage between the old thrombus and the inner aneurysmal wall. The most important histological feature was the many clefts containing fresh blood clots in the old thrombus near the wall of the distal neck. These clefts were not lined with endothelial cells, and seemed to connect the lumen of the parent artery with the most peripheral fresh hemorrhage. However, the diameter of each of these clefts is apparently not large enough to transmit the blood pressure of the parent artery. Simple dissection of the aneurysmal wall by blood flow in the lumen through many clefts in the old thrombus of the distal neck may be involved in the growth and rupture of thrombosed giant aneurysms of the vertebral artery.  (+info)

Bilateral vertebral artery occlusion following cervical spine trauma--case report. (3/642)

A 41-year-old female presented with a rare case of bilateral vertebral artery occlusion following C5-6 cervical spine subluxation after a fall of 30 feet. Digital subtraction angiography showed occlusion of the bilateral vertebral arteries. Unlocking of the facet joint, posterior wiring with iliac crest grafting, and anterior fusion were performed. The patient died on the 3rd day after the operation. This type of injury has a grim prognosis with less than a third of the patients achieving a good outcome.  (+info)

Outcome of angioplasty for atherosclerotic intracranial stenosis. (5/642)

BACKGROUND AND PURPOSE: We sought to assess the long-term outcome and efficacy of percutaneous transluminal angioplasty in the treatment of symptomatic intracranial atherosclerotic stenoses. METHODS: Twenty-three patients with fixed symptomatic intracranial stenoses were treated over a 5-year period with percutaneous transluminal angioplasty. Patients who underwent successful angioplasty were followed up for 16 to 74 months (mean, 35.4 months). RESULTS: An angioplasty that resulted in decreased stenosis was performed in 21 of 23 patients (91.3%). In 1 case a stenosis could not be safely crossed, and in another balloon dilatation resulted in vessel rupture. This vessel rupture resulted in the 1 periprocedural death in the series. In follow-up there was 1 stroke in the same vascular territory as the angioplasty and 2 strokes in the series overall. This yielded an annual stroke rate of 3.2% for strokes in the territory appropriate to the site of angioplasty. CONCLUSIONS: Intracranial angioplasty can be performed with a high degree of technical success. The long-term clinical follow-up available in this series suggests that it may reduce the risk of future stroke in patients with symptomatic intracranial stenoses.  (+info)

Clinical and neuroradiological features of intracranial vertebrobasilar artery dissection. (6/642)

BACKGROUND AND PURPOSE: We sought to determine the clinical and neuroradiological features of intracranial vertebrobasilar artery dissection. METHODS: The clinical features and MR findings of 31 patients (20 men and 11 women) with intracranial vertebrobasilar artery dissections confirmed by vertebral angiography were analyzed retrospectively. The vertebral angiography revealed the double lumen sign in 11 patients (13 arteries) and the pearl and string sign in 20 patients (28 arteries). RESULTS: The patients ranged in age from 25 to 82 years (mean, 54.8 years). Clinical symptoms due to ischemic cerebellar and/or brain stem lesions were common, but in 3 cases the dissections were discovered incidentally while an unrelated disorder was investigated. Headache, which has been emphasized as the only specific clinical sign of vertebrobasilar artery dissection, was found in 55% of the patients. Intramural hematoma on T1-weighted images has been emphasized as a specific MR finding. The positive rate of intramural hematoma was 32%. Double lumen on 3-dimensional (3-D) spoiled gradient-recalled acquisition (SPGR) images after the injection of contrast medium was identified in 87% of the patients. The 3-D SPGR imaging method is considered useful for the screening of vertebrobasilar artery dissection. CONCLUSIONS: Intracranial vertebrobasilar artery dissection is probably much more frequent than previously considered. Such patients may present no or only minor symptoms. Neuroradiological screening for posterior circulation requires MR examinations, including contrast-enhanced 3-D SPGR. Angiography may be necessary for the definite diagnosis of intracranial vertebrobasilar artery dissection because the sensitivity of the finding of intramural hematoma is not satisfactory.  (+info)

Perimesencephalic hemorrhage. Exclusion of vertebrobasilar aneurysms with CT angiography. (7/642)

BACKGROUND AND PURPOSE: It is important to recognize a perimesencephalic pattern of hemorrhage in patients with subarachnoid hemorrhage (SAH), because in 95% of these patients the cause is nonaneurysmal and the prognosis is excellent. The purpose of this study was to investigate whether CT angiography can accurately exclude vertebrobasilar aneurysms in patients with perimesencephalic patterns of hemorrhage and therefore replace digital subtraction angiography (DSA) in this setting. METHODS: In 40 patients with posterior fossa SAH as shown on unenhanced CT, 2 radiologists independently evaluated unenhanced CT for distinguishing between perimesencephalic and nonperimesencephalic pattern of hemorrhage and assessed CT angiography for detection of aneurysms. All patients subsequently underwent DSA or autopsy. RESULTS: Observers agreed in 38 of 40 patients (95%) in differentiating perimesencephalic and nonperimesencephalic patterns of hemorrhage on unenhanced CT. On the CT angiograms, both observers detected a vertebrobasilar aneurysm in 16 patients and no aneurysm in 24 patients. These findings were confirmed by DSA or autopsy. No patients with a perimesencephalic pattern of hemorrhage were found to have an aneurysm on either CT angiography or DSA. CONCLUSIONS: Good recognition of a perimesencephalic pattern of hemorrhage is possible on unenhanced CT, and CT angiography accurately excludes and detects vertebrobasilar aneurysms. DSA can be withheld in patients with a perimesencephalic pattern of hemorrhage and negative CT angiography.  (+info)

Management of aneurysms of the vertebral artery-posterior inferior cerebellar artery complex. (8/642)

Aneurysms of the vertebral artery (VA) and posterior inferior cerebellar artery (PICA) account for only about 3% of all diagnosed intracranial aneurysms. The surgical therapy of these aneurysms is complex and difficult due to the close topographical relationship between the neurovascular structures. Here, we report upon 27 patients with 29 such aneurysms. Of these, 22 patients (81%) were hospitalized because of a subarachnoid hemorrhage. Sixteen of these patients (72%) had an additional intraventricular hemorrhage. Twenty-one patients (78%) were surgically treated for their aneurysms, three of them also for an associated arteriovenous malformation. Aneurysms of the VA and the proximal PICA were exposed via a transcondylar (n = 11) or lateral suboccipital (n = 3) approach, those originating from the distal PICA via a paramedian suboccipital (n = 7) route. Endovascular therapy was used in three patients. A patient with a fusiform aneurysm of the vertebrobasilar junction was treated with a ventriculoperitoneal shunt only. Three aneurysms with a complex morphology were not treated. Of the patients operated upon, two died postoperatively due to vasospasm. Two other patients developed an incomplete dorsolateral medullary syndrome. One individual was lost for follow-up. The median follow-up period was 4.6 years (range 3-86 months). Both, the overall mortality (2/27) and morbidity (2/27) were 7.5%, respectively. Our results show that even complex vascular lesions of the posterior fossa can be treated with a satisfactory long-term outcome in the majority of our patients (85%). The multimodal management and an individually tailored microsurgical approach are key issues for the treatment of such aneurysms.  (+info)

We performed the present study to determine whether the site of occlusion in the vertebrobasilar circulation could be identified by the measurement of blood flow velocity in the bilateral vertebral arteries.. Using color-coded duplex carotid ultrasonography, we measured the time-averaged mean and end-diastolic flow velocities with incident angle correction in 130 bilateral vertebral arteries between the C3 and C6 segments of the spine in 65 stroke patients with or without occlusive diseases in the vertebrobasilar circulation. The site of occlusion was confirmed by cerebral angiography. The subjects included 12 patients with unilateral subclavian artery occlusion (SA group), 11 patients with unilateral occlusion at the origin of the vertebral artery (V1 group), 6 patients with unilateral vertebral artery occlusion before the branching of the posterior inferior cerebellar artery (V2 group), 14 patients with unilateral vertebral artery occlusion after the branching of the posterior inferior ...
A 27-year-old man presented with a huge hematoma in the neck because of a knife wound. Vertebral artery rupture was suspected by ultrasonography. Vertebral arteriography was performed for a possible cover stent placement, and a right vertebral artery rupture was identified. A balloon was placed proximal to the right vertebral artery (Figure 1A). Left vertebral arteriography showed a huge hematoma at the site of the rupture of the right vertebral artery (Figure 1B), and a microcatheter was placed into the right vertebral artery via the left vertebral artery with the tip at the site of rupture (Figure 1C). The distal of vertebral artery was embolized by coils (Figure 1D). The wound and hematoma were treated with surgical irrigation and debridement after the embolization procedure, and the patient recovered without procedure-related complications and side effects at 4 years follow-up. ...
Extracranial vertebral artery aneurysms are extremely rare and account only for 0.5% of all aneurysms. Most extracranial vertebral artery aneurysms are located in the V3 segment followed by the V1 segment.7 These aneurysms are diagnosed secondary to an embolic infarct or incidentally as a palpable mass. Patients with connective tissue disorders, including Ehlers-Danlos syndrome, Marfan syndrome and neurofibromatosis type I are at higher risk of developing extracranial vertebral artery aneurysms. A ruptured vertebral artery aneurysm with local pain and haematoma are often found in this particular group of patients,.3 4 8 In contrast, our case report presents a young patient without any trauma who presented with sudden onset of severe supraclavicular pain. CT angiography and DSA are the standard tools to diagnose and reveal the anatomy of vasculature and to plan treatment. Treatment options include ligation, isolation, balloon embolisation, onyx embolisation and coil embolisation.6 9-11 There is ...
CASE REPORT: A case report of a 58-year-old man who sustained a laceration of his left vertebral artery during a routine corpectomy for cervical myelopathy is reported. OBJECTIVE: To report iatrogenic injury of a tortuous vertebral artery during anterior cervical spine surgery and discuss appropriate diagnosis and treatment options for this complication. SETTING: UMass Memorial Medical Center, Worcester, MA, USA. BACKGROUND DATA: Vertebral artery anomalies, although rare, are typically present with degenerative processes and great care must be taken to avoid damage during a corpectomy. Cross-sectional imaging coupled with intraoperative angiography is helpful for the urgent evaluation of the injury site and identification of the contralateral vertebral arterys status. METHODS: This is a single case of a patient sustaining a laceration of the left vertebral artery during surgery, which resulted in a lateral medullary stroke. RESULTS: After the left vertebral artery laceration, hemostasis was achieved.
The vertebral arteries arise from the subclavian arteries, one on each side of the body, then enter deep to the transverse process of the level of the 6th cervical vertebrae (C6), or occasionally (in 7.5% of cases) at the level of C7. They then proceed superiorly, in the transverse foramen (foramen transversarium) of each cervical vertebra. Once they have passed through the transverse foramen of C1 (also known as the atlas), the vertebral arteries travel across the posterior arch of C1 and through the suboccipital triangle before entering the foramen magnum.. Nunziante Ippolito, a neapolitan physician, indicated the angle of Nunziante Ippolito to find vertebral artery, between anterior scalene muscle and Longus colli muscle.. Inside the skull, the two vertebral arteries join up to form the basilar artery at the base of the medulla oblongata. The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of the brain if there is ...
Methods We retrospectively reviewed cases of ruptured distal vertebral artery or PICA dissecting aneurysms that underwent endovascular treatment. Diagnosis was based on the presence of subarachnoid hemorrhage on initial CT imaging and of a dissecting aneurysm on catheter angiography. Patients with vertebral artery aneurysms were selected for coil embolization of the diseased arterial segment based on the adequacy of flow to the basilar artery from the contralateral vertebral artery. Patients with PICA aneurysms were generally treated only if they were poor surgical candidates. Outcomes included symptomatic and asymptomatic procedure-related cerebral infarction, recurrent aneurysm rupture, angiographic aneurysm recurrence, and estimated modified Rankin Scale (mRS). ...
The vertebral artery is a branch of the subclavian artery and has four segments. The second part courses through the transverse foramen of the C6 vertebra upto C1. There is variation of the course of the vertebral artery in upto 20% of patients with the vertebral artery traversing through the transverse foramen of C7 in 7.5%. The cervical nerve root exits through the intervertebral foramen, posterior to vertebral artery along the groove on the transverse process.. TFCNRI is a diagnostic and often therapeutic treatment for cervical radiculopathy.[3] Variation of normal vertebral anatomy might predispose to accidental injection of local anaesthetic or steroids that could result in serious complications. The normal variation of corkscrew morphology can result in posterolateral displacement of the vertebral artery at one or more levels.[11] An accessory vertebral artery which can lie posterior to the nerve root is a rare anatomic variation and if present and may lie along the path of the needle for ...

I have tachycardia, mitral valve prolapse, some pvcs. I take dixogin and it controls the rapid heart beat pretty well. My change of insurance meant a new cardiologist. I have seen her a few times for chest pains and she has said there was no cause of concern. A scan of my lungs ordered by another dr indicated anomalous origin of left vertebral artery. He didnt know anything about it so I emailed my new cardiologist. Her response stated it is something I was born with and it isnt dangerous. However, I did find limited information that was cause for concern. Supposedly it is crucial to advise surgeons before any neck surgery or angiogram about this condition and that it can mimic stroke symptoms and actually cause strokes, if I understand the jargon correctly.If this is true, then why didnt the cardiologist say anything? I also am concerned that my elderly mom who has already had two strokes and may at some point need an angiogram has not been diagnosed with this same condition. Should I ask ...
ICD-10-PCS code B30F1ZZ for Plain Radiography of Left Vertebral Artery using Low Osmolar Contrast is a medical classification as listed by CMS under Upper Arteries range.
Results Twenty patients experienced progression. Recurrent ischaemic events that occurred in the vertebrobasilar territory were seen in three patients (3.9%). Two of these three patients and other 17 patients showed morphological worsening. None of the patients presented with subarachnoid haemorrhage. The log-rank test showed male sex, migraine, basilar extension and the posterior inferior cerebellar artery involvement were associated with the progression. Multivariate analysis using the Cox proportional hazards model showed that only basilar extension and the posterior inferior cerebellar artery involvement were significantly related to the progression (p=0.012 and 0.019). In addition, patients with these two vertebrobasilar morphologies had a significantly shorter period of progression of siVAD than those without these morphologies (both, median 242 days; one of two, median 1292 days; none, median 2445 days).. ...
Arteries of the Neck and Head ... is the one that provides the blood to the upper right part of the chest, the right arm as well as the head and neck. This is done through an artery branch called the right vertebral artery. The vertebral arteries that are on the left and right, in turn, go into the basilar artery and then upward to the posterior cerebral artery. This provides most of the oxygenated blood to the brain. Both ...
It is the V-2 segment of the vertebral artery that is readily visualized on Color Doppler ultrasound imaging. Yet often the vertebral artery can be difficult to visualize even in the V-2 segment due to the anatomical location of the artery (vertebral bone and cervical musculature). Occlusion or stenosis of the vertebral artery usually occurs at the proximal (V-1) segment. Hence color Doppler ultrasound study of the intertransverse segment (V-2) may often be normal. In stenosis of the subclavian artery proximal to the origin of the vertebral artery, there may be reversed flow through the vertebral artery (a condition known as subclavian steal syndrome). Herein, the arm on the side of subclavian artery stenosis is supplied via reversed flow from the vertebral artery of the opposite side. In the normal individual (color Doppler video clip above), the easiest way to spot retrograde flow is to study the direction of flow in the common carotid artery and the ipsilateral vertebral artery. If both these ...

Introduction: The authors propose a new terminology, Rotational Ischemic Vertebral Artery Compression (RIVAC) syndrome, to describe patients who present with TIA or stroke from compression of the cervical vertebral artery (VA) below C2 by facet hypertrophy or uncinate process osteophyte associated with rotation of the head. The authors review clinical presentation, radiological findings, and management of 7 consecutive cases.. Methods: Prospective analysis of 7 consecutive cases of RIVAC syndrome was performed between 2004 and 2012. We reviewed peri-operative imaging, method of treatment, and clinical and angiographic outcome.. Results: A total of 6 patients (mean 66+/- 4 years) presented with stroke (N=2) or TIA including reproducible dizziness, vertigo, or syncope (N=4) associated with rotation of the head. Pre-operative dynamic cerebral angiogram showed near complete occlusion of cervical VA (N=2) or severe stenosis (60 to 80%) (N=5) during rotation of the head. The location of cervical VA ...
Transverse foramen fractures are of transvserse foramen, an opening on each of the transverse processes that contains vertebral vessels.
Objectives: The aim of this work is to present a case report from a patient diagnosed with a gastrointestinal stromal tumour (GIST), who developed cervical metastasis at C1-C2 level, compromising the right vertebral artery.. Methods: We present a patient with a cervical metastasis from a duodenal GIST. To prevent ischemic complications, the right vertebral artery was occluded prior to the surgery. A review of the relevant literature was performed.. Results: A 69-year-old male, diagnosed in 2014 with a duodenal GIST, peritoneal implants and vertebral metastases was successfully treated with surgery and Imatinib. Two years later, he complained of right-sided neck pain, and presented a stiff and painful retromastoid mass. PET-CT showed a right laterocervical mass at C1-C2 level, located in the paravertebral musculature and infiltrating the C1 transverse foramen and the C1-C2 neural foramen. A core needle biopsy obtained the diagnostic of a GIST metastasis, infiltrating striatal muscle. An MRI ...

Objective: Dominance of arteries has been studied in different tissues/organs of body. Diagnostic, therapeutic and prognostic implications are hypothesized to be related to symmetry or asymmetry of circulation. One major implication in the case of the brain is the hypotheses that asymmetry exists due to differences in vascular requirements of the brain tissue. Vertebral artery origin and … ...
Preoperative planning must take into account the location and course of the vertebral arteries, the degree and locations of any stenosis of the cervical spinal canal as well as the apex of the cervical kyphosis. The greatest concern in planning a high cervical PSO is iatrogenic injury to the spinal cord, nerve roots and vertebral arteries. Flexion-extension films help define the apex of the kyphosis and determine is the kyphosis is amenable to closed reduction. Any patients who demonstrate severe spinal cord compression with associated signal change might not be appropriate candidates for this approach. Although not utilized in this example, dedicated pre-operative imaging of the vertebral arteries would be beneficial when selecting patients best suited for this technique; patients with a single vertebral artery might not be ideal candidates. Study of pre-operative CT imaging helps define the location of the vertebral artery in the foramen transversarium and its relationship to the pedicles as ...
BACKGROUND: Revascularization of the posterior inferior cerebellar artery (PICA) is typically performed with the occipital artery (OA) as an extracranial donor. The p3 segment is the most accessible recipient site for OA-PICA bypass at its caudal loop inferior to the cerebellar tonsil, but this site may be absent or hidden due to a high-riding location. OBJECTIVE: To test our hypothesis that freeing p1 PICA from its origin, transposing the recipient into a shallower position, and performing OA-p1 PICA bypass with an end-to-end anastomosis would facilitate this bypass. METHODS: The OA was harvested, and a far lateral craniotomy was performed in 16 cadaveric specimens. PICA caliber and number of perforators were measured at p1 and p3 segments. OA-p3 PICA end-to-side and OA-p1 PICA end-to-end bypasses were compared. RESULTS: OA-p1 PICA bypass with end-to-end anastomosis was performed in 16 specimens; whereas, OA-p3 PICA bypass with end-to-side anastomosis was performed in 11. Mean distance from OA at the

Owls can rotate their heads and necks about 270°. Owls have 14 neck vertebrae as compared to seven in human beings, that makes their necks extra flexible. They even have adaptations to their circulatory techniques, allowing rotation with out removing blood into the brain: the foramina inside their vertebrae by which the vertebral arteries pass are about 10 moments the diameter on the artery, as opposed to with regard to the exact same dimensions as the artery as in people; the vertebral arteries enter the cervical vertebrae better than in other birds, giving the vessels some slack, as well as the carotid arteries unite in a very huge anastomosis or junction, the most important of any chickens, protecting against blood supply from currently being Slash off whilst they rotate their necks. Other anastomoses amongst the carotid and vertebral arteries aid this effect.[one][2 ...

in a good hanging, the victim should not strangle to death (1). A good hanging should be set up such that there is a fall just far enough so that the first and second vertebral bodies are separated, breaking the neck and quickly killing the victim. You do not want them to fall too far, as the head may come clean off and that is aesthetically unpleasant. Most people who die these days from hanging do not get a good hanging; they suffocate at the end of a rope, a particularly gruesome way to die. The vertebral artery is often damaged in suicidal hanging (2); The vertebral artery was shown to be injured quite frequently (rupture, intimal tear, sub-intimal hemorrhage), namely in one quarter of all cases, and indeed in more than half taking into account the perivascular bleeding. This easy injury is in part due to mechanical reasons The vertebral arteries appear to be particularly susceptible to injury in trauma of the cervical spine because of their close anatomical relationship to the spine ...
Nine months later during a coughing fit caused by my allergies, I broke an artery in my neck! Three days later I was a very, very sick woman. I had suffered at stroke as a result of the broken artery. Dissection of the Right Vertebral Artery was the medical term for it. I was 31 years old. I spend 2 weeks in the hospital. As a result of the stroke, I had to use a cane for a while, couldnt hardly use my right hand, had to learn to write again, couldnt talk correctly and had some short term memory loss. I have recovered about 95%. I have to stay on medicine due to the brain damage from the stroke and my right arm is still weak at times. It could have been so much worse! ...
Apparatus and methods for treatment of stroke are provided. In a preferred embodiment, the present invention disposes at least one catheter having a distal occlusive member in either the common carotid artery (CCA) or both the vertebral artery (VA) and the CCA on the hemisphere of the cerebral occlusion. Blood flow in the opposing carotid and/or vertebral arteries may be inhibited. Retrograde or antegrade flow may be provided through either catheter independently to effectively control cerebral flow characteristics. Under such controlled flow conditions, a thrombectomy device may be used to treat the occlusion, and any emboli generated are directed into the catheter(s).

Arteriography has shown that when a subject positions the neck in extension and external rotation, the circulation is compromised on the side contralateral to the rotation (Fig. 8). The proximity of the vertebral artery to the cervicooccipital junction explains the possibility of injury to the arterial wall that may occur with inappropriate maneuvers of the cervical spine. Serious accidents have been described after certain manipulations, or even after some prolonged abnormal postures of the cervical spine that can result in vertebral artery compression and thus restrict blood flow between the atlas and the occiput.

On Monday July 16, 2012, Elis cardiologist will take him before the surgery team to discuss his subclavian steal syndrome. He apparently has been going back and forth with some other doctors and gathering data to present to the team. There are several options and things to consider. Of course they always go from the most invasive to the least invasive. The most invasive is of course is full on heart surgery. This would be very risky since what they would do is bypass surgery. They would take an artery from somewhere else and put it in the spot where Elis artery doesnt exsist. This is where Elis original heart problem is though so if his aorta recoarcs then the vessel could tear and kill him almost instantly. This is EXTREMELY risky and most likely NOT the way they will proceed. Another option is to tie off the left vertebral artery (the artery that goes to Elis brain that now that is stealing the oxygenated blood from his brain). This apparently is normally done during the original surgery, ...
On August 22nd, 2012 at age 37, I had left work and was driving to pick my children up at Boys and Girls Club. I suddenly had the sensation that my view of the world outside my front windshield was slowly turning upside down. I pulled off into a parking lot and called my fiance to explain, as best I could, what was happening to me and that I did not think I should be driving. He left work, picked up our kids and came to get me. This only took about 15 minutes and by the time they found me I was vomiting into the parking lot landscaping. I got into the car and continued to vomit out the open window as he drove me to Providence Regional Medical Center in Everett, WA.. The ER doctor asked questions like, Have you taken any illegal drugs? and could not discover what was causing my symptoms. I had a headache, which had been bothering me consistently for the past month so they gave me an MRI. The images showed a blood clot in my left vertebral artery which had partially dislodged and hit the left ...
