Texas Radiology Associates (TRA) is a physician-owned practice made of more than 90 fellowship-trained radiologists encompassing all of the subspecialties in radiology.
Cerebral angiography is a form of angiography which shows images of blood vessels in and around the brain, thereby allowing detection of abnormalities such as aneurysms, arteriovenous malformations, fistulas, and tumors.
Typically a catheter is inserted into a large artery (such as the femoral, brachial, or radial artery) and threaded through the circulatory system to the carotid, vertebral, or subclavian artery, where a contrast agent (dye) is injected. For some applications, and in particular when dynamic information is useful or necessary, this method yields better diagnostic information than less invasive methods, such as computed tomography angiography (CTA) and magnetic resonance angiography (MRA). In addition, cerebral angiography allows certain treatments to be performed immediately, based on its findings.
Venography can also be used to distinguish blood clots from obstructions in the veins, to evaluate congenital vein problems, and to measure pressure difference between different venous structures across areas of narrowing. The term stroke, or cerebrovascular accident (CVA), is a broad term generally indicating a sudden neurologic deterioration secondary to one of two etiologies: 1) a clot in one of the arteries supplying flow to the brain, or an “ischemic stroke”, or 2) bleeding into the brain. The mainstay of treatment for acute ischemic stroke involves administration a clot dissolving drug called tPA (tissue plasminogen activator) through a vein in the arm or leg. However, the treatment of acute ischemic stroke is continuously evolving as new technology develops. Furthermore, these mechanical methods for flow restoration may be offered to some patients that cannot safely receive intravenous tPA, either because they have a contraindication to receiving the medication or because too much time has lapsed between their symptom onset and their arrival at the hospital. An intracranial aneurysm (also called cerebral aneurysm or brain aneurysm) is a cerebrovascular disorder in which weakness in the wall of a cerebral artery causes a localized outpouching or ballooning of the blood vessel.
If an aneurysm ruptures, blood leaks into the thin coverings of the brain called the subarachnoid space. Arteriovenous malformations (AVMs) and arteriovenous fistulas (AVFs) occur when an abnormal connection develops between arteries and veins in the brain or dura (i.e. A brain AVM is an abnormal connection between the cerebral arteries and veins, bypassing the capillary system, located within the brain parenchyma. A dural arteriovenous fistula (dAVF) is an abnormal direct connection (fistula) between a meningeal artery and a meningeal vein or dural venous sinus.
Whether it is the mechanical retrieval of a thromboembolic occlusion of a blood vessel in the brain or medical dissolution of a blood clot using direct infusion of medicine at the clot face, large vessel occlusions responsible for symptoms of acute stroke may be treated with interventional neuroradiology, as an adjunct to intravenous tPA (clot buster) administration, which is the current standard of care. A stent is a tubular piece of mesh that can be placed inside of a blood vessel to maintain the blood vessel’s patency.
Flow restoration may rapidly re-establish oxygen supply in the brain region that has been deprived of oxygen and nutrients that the blood.
Particularly advantageous is that the stent is applicable repeatedly and can be used even in small peripheral brain blood vessel branches (eg, M2 segments).
The carotid arteries are blood vessels in the neck that circulate oxygenated blood and nutrients from the heart to the brain. Carotid artery angioplasty and stenting is performed for the treatment of carotid artery stenosis. An empty and collapsed balloon on a guide wire, known as a balloon catheter, is passed into the narrowed carotid artery and then inflated to a fixed size. A stent (tubular piece of mesh) is then routinely deposited to ensure that the vessel remains open. Idiopathic intracranial hypertension (IIH), sometimes called by the older names benign intracranial hypertension (BIH) or pseudotumor cerebri (PTC), is a neurological disorder that is characterized by increased intracranial pressure (pressure around the brain) in the absence of a tumor or other disease. The symptoms are headache, nausea, and vomiting, and sometimes pulsatile tinnitus (buzzing in the ears synchronous with the pulse), diplopia (double vision) and other visual symptoms. Older treatments of IIH included repeat lumbar punctures, medications that decrease production of CSF, surgical decompression of the optic nerve (optic nerve sheath fenestration), surgical shunting of the CSF from the spine to the abdomen (lumboperitoneal shunt), CSF shunting from the brain to the abdomen (ventriculoperitoneal shunt), and even CSF shunting from the brain to the heart (ventriculoatrial shunt). Various tumors in the brain, head, neck, and spine can be treated pre-operatively with embolization to reduce the risk of bleeding during open surgery. The list of tumors amenable to this therapy is very broad and includes meningiomas, glomus tumors, paragangliomas, nasopharyngeal angiofibromas, as well as metastatic cancerous tumors from the lung, breast, kidney, skin, and bowel.

The procedure involves diagnostic angiography followed by angiographic guided selection of the small arteries that supply blood flow to the tumor. Next, small particles are injected in order to reduce blood flow and induce ischemia within the tumor tissue.
Spinal arteriovenous fistulas (AVFs) are uncommon vascular lesions that occur in the spine. Patients become symptomatic because the AVF causes spinal cord venous congestion and hypertension, resulting in hypoperfusion, hypoxia, and edema of the spinal cord. Spinal arteriovenous malformations (AVMs) are an even more uncommon vascular lesion the spine.
Both spinal AVFs and spinal AVMs can be treated endovascularly with embolization using liquid embolics, such as Onyx and n-BCA, and with open surgery.
Vertebral augmentation is a general medical term used to describe a group of procedures that include vertebroplasty, kyphoplasty, and sacroplasty.
Epidural Steroid Injections Epidural steroid injection (ESI) is a technique for relieving pain from spinal stenosis and spinal disc herniation.
Facet Joint Injections The zygapophysial joint or facet joint is a synovial joint between the superiorarticular process of one vertebra and the inferior articular process of the vertebra directly above it. Synovial Cyst Injection and Rupture A synovial cyst of the facet joint is a non-neoplastic cystic lesion that develops as a response to the biomechanical stressors that are placed upon the synovial lined joints of the spine, the facet joints. A series of radiographs are taken as the contrast agent spreads through the brain’s arterial and venous systems.
If, for example, the images reveal an aneurysm, metal coils may be introduced through the catheter already in place and maneuvered to the site of aneurysm; over time these coils encourage formation of connective tissue at the site, strengthening the vessel walls. Currently available devices are able to be navigated through the arteries in the neck and brain to retrieve or aspirate clots and remove large blockages that may not dissolve with intravenous tPA administration. Although many AVMs are asymptomatic, AVMs in the brain can cause headache, intracranial bleeding, and lead to other serious neurologic problems, such as seizures. Like other vascular malformations, a dural AVF can be treated endovascularly with embolization using liquid embolics, such as Onyx and n-BCA, by open surgery, or by gamma knife radiosurgery.
In the setting of acute ischemic stroke, stent placement enables entrapment of the thrombus between the stent and the vessel wall to provide fast recanalization and to restore antegrade blood flow. Stent retrievers allow thrombectomy to be performed by first deploying the stent inside of the clot and then pulling back the deployed stent into the guide catheter. In contrast to conventional stent systems, stent retrievers require no anticoagulation, as the stent is not deployed permanently. The carotid arteries are located anteriorly on both sides of your neck and carry blood to the majority of the brain.
The technique of the procedure involves mechanically widening narrowed or obstructed carotid arteries that is usually the result of atherosclerosis. The balloon forces expansion of the blood vessel wall for improved flow, and the balloon is then deflated and withdrawn. An embolization protection device may be used during the procedure to prevent the atherosclerotic plaque from the narrowed vessel wall from migrating to the brain during the procedure and causing symptoms of stroke. Using a needle, relatively small amounts of corticosteroids together with a local anesthetic are injected into the epidural space around the spinal cord and spinal nerves. When cysts arise from these joints, they may press upon critical neurologic structures, including the ventral nerve roots and the spinal cord.
Normally the catheter is inserted by the vessels in the groin and moved to the appropriate site by navigating through the vascular system. Vascular malformations can be treated endovascularly with embolization using liquid embolics, such as Onyx and n-BCA, by open surgery, or by gamma knife radiosurgery.
In this scenario, the struts of the stent engage the thrombotic material and allow removal of the clot from the patient’s body. The vertebral arteries are the smaller, more posteriorly located arteries located on both sides of your neck that carry blood to the back of the brain and brainstem.

The procedure is technically similar to that described for cervical carotid artery angioplasty and stenting, although the angioplasty balloons and intracranial stents are smaller and more flexible than those used in the cervical circulation. The biomechanical function of each pair of facet joints is to guide and limit movement of that spinal motion level.
These benign yet painful cysts may be treated by performing synovial cyst injection and rupture.

The anti-inflammatory effect of the corticosteroid is responsible for providing pain relief when radiculopathy exists. The procedure involves cyst puncture under CT or fluoroscopic guidance followed by the high pressure injection of fluids, including injection of long acting local analgesics and corticosteroid suspensions. Spinal AVMs are extremely rare lesions that develop before birth or develop at a very early age for reasons that are not entirely understood. Mohamed Sheeraye - Carotid body tumor- Hopital de Balbala- Djibouti 40 YRS OLD FEMALE WITH - UNCONTROLLED HYPERTENSION - MASS RT SIDE OF THE NECKGlomus Tympanicum Pulsation Glomus tympanicum is a slow growing benign vascular tumour involving the middle ear.
It is derived form glomus bodies which are chemoreceptors found along certain blood vessels and nerves within the proximity of middle ear region.
Its presenting symptoms include hearing loss (conductive type), pulsing tinnitus, ear pain or rarely bleeding from the ear. This video shows a pulsatile red vascular mass (synchronous with the patient heart beat) at its typical position (behind the lower quadrant of the middle ear). The Glomus-group is sent to investigate the case and in the end the butler is the murderer.
Several authors have suggested that the carotid body tumor represents a proliferative response of the normal organ to some unknown disturbance within the nervous system, rather than a true neoplasm. Bungeler (1952) suggested that this was some form of adaptive hyperplasia, which was produced by traumatic destruction of the cortical projection fields of the X nerve. In contrast to this hypothesis, is the realization that a significant number of these lesions undergo malignant transformation with metastasis, which establishes the carotid body tumor as a true neoplasm.
Study of the familial occurrence of chemodectomas has established a definite genetic influence in the development of these neoplasms. They proposed that hypoxia, acting from birth, served as a stimulus for chemoreceptor tissue hyperplasia, which eventually led to tumor formation. There is subjective tinnitus where the ringing or the wheezing is heard by the patient alone and objective tinnitus in which the doctor can also hear the noise by using acoustic instruments. Some of these are unilateral (can be heard in one ear) or bilateral where it is heard in both the ears. Persons suffering from Pulsatile Tinnitus can hear their own heartbeats while Somatic Tinnitus resonances lie outside the ear, probably beyond the cochlear nerves and is believed to arise from central crosstalk within the grey matters. Atheroscl*** Carotid Artery Disease in which the arteries become narrowed due to heavy cholesterol buildup that result in uneven blood flow to the head and neck area. Glomus tumor that consists of bunches of tissues and entangled blood vessels in the ear or the immediate surrounding area can become a cause of tinnitus. Intracranial vascular lesion often causes tinnitus of aneurism and arteri-venous malformation or deformity that is usually typified by abnormal or irregular connection between the artery and the vein..
