Brain Tumor Procedures

Astrocytoma

An astrocytoma is a type of brain tumor that originates from cells called astrocytes, which are a type of glial cell. Glial cells provide support and nourishment to neurons in the brain. Astrocytomas can occur in various parts of the brain and spinal cord.

Awake Mapping Surgery

Awake mapping surgery, also known as awake craniotomy or awake brain surgery, is a specialized surgical technique performed on patients with brain tumors or lesions that are located in or near critical brain areas responsible for vital functions, such as language, motor control, and sensory perception. The purpose of awake mapping surgery is to precisely identify and protect these critical brain regions during tumor removal while minimizing the risk of postoperative neurological deficits.

Brain Cancers (Glioma)

A glioma is a type of tumor that originates from glial cells in the brain or spinal cord. Glial cells are supportive cells that surround and nourish neurons. Gliomas are the most common type of primary brain tumors, meaning they start in the brain rather than spreading from other parts of the body.

Brain Cysts

Brain cysts are fluid-filled sacs that can develop within the brain. They are noncancerous and are generally considered benign. Brain cysts can vary in size and location, and they can be present from birth (congenital) or develop later in life.

Brain Metastases

Brain metastases refer to secondary tumors that have spread to the brain from cancer originating in another part of the body. These tumors are more common than primary brain tumors, which originate within the brain itself. Brain metastases occur when cancer cells break away from the primary tumor site and travel through the bloodstream or lymphatic system to reach the brain.

Fluorescence-Guided Tumor Surgery

Fluorescence-guided tumor surgery is a surgical technique that utilizes fluorescent dyes or contrast agents to enhance the visualization and precise removal of tumor tissue during surgery. The technique involves the administration of a fluorescent agent that selectively accumulates in tumor cells, making them glow or emit fluorescence under specific lighting conditions.

Glioblastoma Multiforme

Glioblastoma multiforme (GBM) is a highly aggressive and malignant type of brain tumor that belongs to the group of gliomas. It is the most common form of primary brain cancer in adults. GBM tumors are characterized by their rapid growth, invasive nature, and ability to affect various regions of the brain.

Laser Tumor Ablation (LITT)

Laser Tumor Ablation, also known as Laser Interstitial Thermal Therapy (LITT), is a minimally invasive surgical technique used to treat tumors in the brain or other parts of the body. It involves the use of laser energy to heat and destroy the tumor cells while minimizing damage to surrounding healthy tissue.

Meningiomas

Meningiomas are tumors that originate from the meninges, which are the protective membranes that cover the brain and spinal cord. Meningiomas are typically slow-growing and are usually noncancerous (benign), although in rare cases they can be malignant.

Metastatic Brain Tumors

Metastatic brain tumors, also known as secondary brain tumors, are tumors that have spread to the brain from cancer originating in another part of the body. These tumors are more common than primary brain tumors, which originate within the brain itself.

Neuro-Oncology

Neuro-oncology is a specialized field of medicine that focuses on the diagnosis and treatment of tumors affecting the central nervous system, which includes the brain, spinal cord, and surrounding structures. Neuro-oncology combines principles of neurology, neurosurgery, oncology, and other related disciplines to manage and care for patients with brain and spinal cord tumors.

Primary Brain Tumors

Primary brain tumors are tumors that originate within the brain itself, rather than spreading from cancer in other parts of the body. These tumors develop from various types of cells in the brain, including glial cells (such as astrocytes, oligodendrocytes, and ependymal cells) or cells within the brain’s supporting structures (such as meninges).

Stereotactic Radiosurgery

Stereotactic radiosurgery (SRS) is a non-invasive technique used to deliver highly precise and concentrated radiation to target specific areas within the brain or other parts of the body. Despite its name, SRS does not involve traditional surgery and does not require any incisions or invasive procedures.

Skull Base Procedures

Cushing's Disease

Cushing’s disease, also known as pituitary Cushing’s syndrome, is a rare endocrine disorder characterized by the excessive production of cortisol, a hormone normally produced by the adrenal glands. The condition is caused by a benign pituitary adenoma, a non-cancerous tumor of the pituitary gland, which secretes an excess amount of adrenocorticotropic hormone (ACTH). ACTH stimulates the adrenal glands to produce cortisol, leading to the characteristic symptoms of Cushing’s disease.

Endoscopic Skull Base Surgery

Endoscopic skull base surgery is a minimally invasive surgical technique performed to access and treat conditions affecting the skull base using an endoscope. The endoscope is a long, thin tube with a light and camera at the tip, allowing the surgeon to visualize the surgical field on a monitor.

Hemi-Facial Spasm

Hemi-facial spasm is a neurological disorder characterized by involuntary muscle contractions or spasms on one side of the face. The spasms usually begin in the muscles around the eye and can gradually spread to involve other facial muscles, including the cheek, mouth, and jaw.

Pituitary Tumors, Endoscopic Endonasal Removal

Endoscopic endonasal removal of pituitary tumors is a minimally invasive surgical technique used to access and remove pituitary tumors through the nasal passages. This approach avoids the need for traditional open skull surgery, resulting in shorter hospital stays, faster recovery times, and reduced risk of complications.

Removal of Skull Base Tumors

The removal of skull base tumors refers to surgical procedures aimed at removing tumors located in the skull base region. These surgeries are complex and require a multidisciplinary approach involving neurosurgeons, otolaryngologists (ear, nose, and throat specialists), and other specialists.

Skull Base CSF Leaks

Skull base cerebrospinal fluid (CSF) leaks refer to the abnormal leakage of cerebrospinal fluid from the skull base region. The skull base is the bottom part of the skull that separates the brain from the structures of the face and neck. CSF leaks can occur as a result of trauma, surgery, underlying medical conditions, or spontaneously.

Skull Base Surgery / Surgeries

Skull base surgery refers to a specialized type of surgical procedure performed to treat conditions affecting the skull base, which is the area at the bottom of the skull where the brain meets the structures of the face and neck. The skull base is a complex region containing critical nerves, blood vessels, and vital structures.

Trigeminal Neuralgia

Trigeminal neuralgia, also known as tic douloureux, is a severe facial pain disorder that affects the trigeminal nerve, which is responsible for transmitting sensations from the face to the brain. It is characterized by sudden, intense, and recurring episodes of excruciating facial pain that can be triggered by even mild stimuli, such as eating, talking, or brushing teeth.

Vestibular Schwannomas / Acoustic Neuromas

Vestibular schwannomas, also known as acoustic neuromas, are benign tumors that develop from the Schwann cells of the vestibulocochlear nerve, which is responsible for transmitting sound and balance information from the inner ear to the brain. These tumors typically arise from the vestibular portion of the nerve, which is responsible for balance.

Neurovascular Procedures

Arteriovenous Malformation (AVM) Embolization and Resection

Arteriovenous Malformation (AVM) embolization and resection are two treatment options for arteriovenous malformations, which are abnormal tangles of blood vessels in the brain or spinal cord. AVMs consist of abnormal connections between arteries and veins, bypassing the capillary network.

AV Fistulas

Arteriovenous fistulas (AV fistulas) are abnormal connections or passageways between an artery and a vein. Normally, arteries carry oxygenated blood away from the heart to the body’s tissues, while veins carry deoxygenated blood back to the heart. In an AV fistula, the direct connection between an artery and a vein bypasses the capillary network, resulting in abnormal blood flow patterns.

Brain Aneurysm Coiling and Clipping

Brain aneurysm coiling and clipping are two different treatment approaches for managing a brain aneurysm, which is a bulge or ballooning in a blood vessel in the brain. These procedures aim to prevent the risk of rupture and subsequent bleeding, which can lead to a potentially life-threatening condition known as a subarachnoid hemorrhage.

Carotid Artery Diseases

Carotid artery disease refers to the narrowing or blockage of the carotid arteries, which are the major blood vessels that supply oxygenated blood to the brain, head, and neck. It is typically caused by the buildup of fatty deposits called plaques within the inner lining of the arteries, a condition known as atherosclerosis.

Carotid Artery Dissection

Carotid artery dissection is a condition characterized by a tear or rupture in the layers of the carotid artery, which is one of the main blood vessels supplying blood to the brain, head, and neck. This tear can lead to the formation of a blood clot, which can partially or completely block blood flow through the artery.

Carotid-Cavernous Fistulas

Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus, a venous structure located at the base of the skull. The carotid artery is a major blood vessel that supplies oxygenated blood to the head and brain, while the cavernous sinus is a network of veins that drain blood from the brain.

Carotid Endarterectomy (CEA)

Carotid endarterectomy (CEA) is a surgical procedure performed to remove plaque buildup from the carotid arteries, which are the major blood vessels in the neck that supply oxygenated blood to the brain. Plaque is composed of fatty deposits and other substances that can accumulate within the arteries and cause narrowing or blockage, a condition known as carotid artery stenosis.

Carotid Stents

Carotid stenting is a minimally invasive procedure used to treat carotid artery disease. It involves the placement of a stent, which is a small metal mesh tube, into the carotid artery to open and support the narrowed or blocked artery.

Cavernous Malformations

Cavernous malformations, also known as cavernous angiomas or cavernomas, are abnormal clusters of blood vessels found in the brain or spinal cord. These malformations are characterized by dilated, thin-walled blood vessels that resemble small “caverns” or cavities filled with blood.

EC / IC Bypass Surgery

EC / IC bypass surgery, also known as extracranial-intracranial bypass surgery, is a surgical procedure performed to restore or improve blood flow to the brain when there is a significant blockage or narrowing of the major blood vessels supplying the brain.

Evacuation of Intra Cerebral Hemorrhage Procedures

Evacuation of intracerebral hemorrhage (ICH) refers to the surgical removal or reduction of bleeding that occurs within the brain tissue. This procedure aims to alleviate pressure on the brain and minimize damage caused by the accumulation of blood.

Hemicraniectomy

Hemicraniectomy is a surgical procedure in which a part of the skull is removed to relieve pressure on the brain. It is typically performed in cases of severe brain swelling, often caused by conditions such as traumatic brain injury, stroke, or brain tumors.

Idiopathic Intracranial Hypertension (Pseudo Tumor Cerebri)

Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a condition characterized by increased pressure inside the skull without an identifiable cause. “Idiopathic” means that the cause is unknown, and “intracranial hypertension” refers to the increased pressure in the skull.

Intracranial Stents

Intracranial stents are devices used in neurosurgery to treat certain conditions affecting the blood vessels within the brain. These stents are similar to those used in other parts of the body, but they are specifically designed for use in the delicate and narrow blood vessels of the brain.

Micro-Vascular Decompression for Facial Pain / Trigeminal Neuralgia

Microvascular decompression (MVD) is a surgical procedure used to treat certain types of facial pain, including trigeminal neuralgia. It is considered a highly effective treatment option for patients who have not responded well to medications or who experience intolerable side effects from medication.

Moyamoya Disease

Moyamoya disease is a rare progressive vascular disorder that affects the blood vessels in the brain, particularly the arteries at the base of the brain. The name “moyamoya” means “puff of smoke” in Japanese, describing the appearance of the tiny blood vessels that form to compensate for the blocked or narrowed arteries.

Pulsatile Tinnitus

Pulsatile tinnitus is a type of tinnitus characterized by hearing a rhythmic sound or pulsing sensation in the ears. Unlike the more common form of tinnitus, which is often described as a constant ringing or buzzing noise, pulsatile tinnitus is associated with the perception of a rhythmic or pulsing sound that coincides with the heartbeat.

Spinal AVM (Arteriovenous Malformations)

A spinal arteriovenous malformation (AVM) is an abnormal tangle of blood vessels in the spinal cord. It is a type of vascular malformation that involves abnormal connections between arteries and veins in the spinal cord. AVMs in the spinal cord disrupt the normal blood flow and can cause a variety of symptoms and complications.

Spine Fistulas

Spinal fistulas, also known as spinal dural arteriovenous fistulas (SDAVFs), are abnormal connections or passageways between the arteries and veins in the spinal cord. These fistulas occur within the dural covering of the spinal cord, which is the outermost protective layer.

Stroke (Cerebrovascular Accident) – CVA

A stroke, also known as a cerebrovascular accident (CVA), is a medical condition that occurs when the blood supply to a part of the brain is interrupted or reduced, depriving the brain tissue of oxygen and nutrients. This can cause brain cells to become damaged or die within minutes.

Thrombectomy for Ischemic Stroke

Thrombectomy is a specialized procedure performed to remove a blood clot (thrombus) that is causing an ischemic stroke. It is a highly effective treatment option for certain patients who have experienced a severe stroke caused by a large artery blockage.

Transcarotid Artery Revascularization (TCAR)

Transcarotid artery revascularization (TCAR) is a minimally invasive surgical procedure used to treat carotid artery stenosis, a condition where the carotid arteries in the neck become narrowed or blocked due to plaque buildup. TCAR combines elements of both traditional carotid endarterectomy (CEA) and carotid artery stenting (CAS) techniques.

Spine Procedures

Cerebrospinal Fluid Leak Repair

Cerebrospinal fluid (CSF) leak repair refers to the surgical or non-surgical procedures performed to locate and repair a leak in the protective fluid-filled sac that surrounds the brain and spinal cord, called the dura mater. CSF leaks can occur spontaneously or as a result of trauma, surgery, or underlying medical conditions.

Spontaneous Intracranial Hypotension

Spontaneous intracranial hypotension (SIH) is a condition characterized by low cerebrospinal fluid (CSF) pressure within the skull, which can lead to various symptoms and complications. It is typically caused by a spontaneous cerebrospinal fluid leak, where the fluid that surrounds and cushions the brain and spinal cord leaks out.
