- Introduction. Intracavernous aneurysms of the carotid artery (ICAs) can produce symptoms through mass effect of the aneurysm on adjacent structures or through rupture, which leads to carotid cavernous fistula or occasionally to subarachnoid hemorrhage (SAH) if the aneurysm extends through the dura.n one patient, one aneurysm was treated by occlusion of the parent vessel and the other by embolization with coils. In the fifth patient, both aneurysms were treated by balloon occlusion.

What is an Aneurysm? Weak, Bulging Artery Wall An aneurysm is an abnormal bulging out or ballooning of a portion of the artery, usually due to weakness of the arterial wall. The aneurysm may enlarge and rupture, often with disastrous consequences.

cerebral aneurysm A cerebral aneurysm occurs at a weak point in the wall of a blood vessel (artery) that supplies blood to the brain. Because of the flaw, the artery wall bulges outward and fills with blood.This bulge is called an aneurysm.An aneurysm can rupture, spilling blood into the surrounding body tissue.erry aneurysm (brain aneurysm) a small saccular aneurysm of a cerebral artery, usually at the junction of vessels in the circle of Willis; such aneurysms frequently rupture, causing subarachnoid hemorrhage.

Aneurysm An aneurysm is an abnormal widening or ballooning of a part of an artery due to weakness in the wall of the blood vessel. It is not clear exactly what causes aneurysms. Some aneurysms are present at birth (congenital). Defects in some parts of the artery wall may be a cause. Common locations for aneurysms include: 1  Major artery from the heart (the aorta) 2  Brain (cerebral aneurysm)  Behind the knee in the leg (popliteal artery aneurysm)

A to Z List of Neurological Disorders 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 diseases.

- An aneurysm or aneurism (from Greek: ἀνεύρυσμα, aneurysma, dilation, from ἀνευρύνειν, aneurynein, to dilate) is a localized, blood-filled balloon-like bulge in the wall of a blood vessel.neurysms can occur in any blood vessel, with examples including aneurysms of the circle of Willis in the brain, aortic aneurysms affecting the thoracic aorta, and abdominal aortic aneurysms. Aneurysms can also occur within the heart itself.

Aortic Aneurysm - Topic Overview An aortic aneurysm (say a-OR-tik AN-yuh-rih-zum) is a bulge in a section of the aorta, the body's main artery. The aorta carries oxygen-rich blood from the heart to the rest of the body. Because the section with the aneurysm is overstretched and weak, it can burst.lood flow often slows in the bulging section of an aortic aneurysm, causing clots to form. If a blood clot breaks off from an aortic aneurysm in the chest area, it can travel to the brain and cause a stroke. Blood clots that break off from an aortic aneurysm in the belly area can block blood flow to the belly or legs.

Aneurysm Cerebral aneurysms, also known as intracranial or brain aneurysms, occur most commonly in the anterior cerebral artery, which is part of the circle of Willis. This can cause severe strokes leading to death. The next most common sites of cerebral aneurysm occurrence are in the internal carotid artery.

- Many reports on endovascular treatment of intracavernous aneurysms by balloon occlusion or coiling have now been published, but a systematic review of the risks and effectiveness of the two endovascular treatment modalities is lacking.n one patient, one aneurysm was treated by occlusion of the parent vessel and the other by embolization with coils. In the fifth patient, both aneurysms were treated by balloon occlusion.

Intraoperative floppy iris syndrome This syndrome is characterized by a flaccid iris which billows in response to ordinary intraocular fluid currents, a propensity for this floppy iris to prolapse towards the area of cataract extraction during surgery, and progressive intraoperative pupil constriction despite standard procedures to prevent this.FIS has been associated with Flomax (tamsulosin), a medication widely prescribed for urinary symptoms associated with benign prostatic hyperplasia. Tamsulosin is a selective alpha blocker that works by relaxing the bladder and prostatic smooth muscle.

Cerebral Aneurysm A cerebral aneurysm (also called an intracranial aneurysm or brain aneurysm) is a bulging, weakened area in the wall of an artery in the brain, resulting in an abnormal widening, ballooning, or bleb. Because there is a weakened spot in the aneurysm wall, there is a risk for rupture (bursting) of the aneurysm.

Lacunar stroke Lacunar stroke or lacunar infarct (LACI) is a type of stroke that results from occlusion of one of the penetrating arteries that provides blood to the brain's deep structures.

This can cause severe strokes leading to death. The next most common sites of cerebral aneurysm occurrence are in the internal carotid artery.neurysms are a result of a weakened blood vessel wall, and can be a result of a hereditary condition or an acquired disease. Aneurysms can also be a nidus for clot formation (thrombosis) and embolization.

- Although the mature hemodialysis arteriovenous fistula is associated with fewer complications compared with other types of vascular access, when problems occur, they need to be managed effectively. The main causes of failure in a mature hemodialysis arteriovenous fistula are vascular stenotic lesions. These lesions manifest as decreased flow leading to inadequate dialysis and eventually thrombosis. Failure of the mature AVF and management will be reviewed here. Primary failure of the newly created hemodialysis arteriovenous fistula is reviewed separately as are other types of AVF dysfunction, such as hemodialysis ischemic syndrome, aneurysm formation, infection, and excess flow leading to congestive heart failure are discussed separately.

Ascending and Aortic Arch Aneurysms This type of aneurysm is located above the heart and can cause the aortic valve to leak. An aortic arch aneurysm is a bulge in the portion of the aorta closest to the heartlocated away from the heart and can involve the blood vessels that supply to your head and neck.

Peripheral Arterial Disease (PAD) / Peripheral Vascular Disease (PVD) Interventional radiologists are vascular experts who offer minimally invasive treatment for abdominal aortic aneurysm. An aortic aneurysm is a weak area in the aorta, the main blood vessel that carries blood from the heart to the rest of the body.As blood flows through the aorta, the weak area bulges like a balloon and can burst if the balloon gets too big.hree out of four aneurysms show no symptoms at the time they are diagnosed. When symptoms are present, they may include: 1  Abdominal pain (that may be constant or come and go). 2  Pain in the lower back that may radiate to the buttocks, groin or legs.
