Basilar Aneurysms

Basilar Aneurysms - Irfacilities


Aneurysms of the basilar trunk artery are extremely rare, accounting for only 2.1 per cent of all intracranial aneurysms. They're most common in people over 60, have a little male predominance, and are linked to a high rate of morbidity and mortality. Aneurysms can have a variety of causes, including atherosclerosis (the most frequent), traumatic, mycotic, or vasculitic.

Aneurysm of the basilar tip. A type of posterior circulation cerebral aneurysm that accounts for just a small percentage of all aneurysms, with 90% occurring in the anterior circulation. Cerebral aneurysms are common around bifurcations, such as this one, which has the posterior cerebral artery running directly behind it. A basilar artery stroke is a sort of posterior stroke that affects the back of the brain's circulation. This type of stroke can manifest in a variety of ways since the basilar artery sends blood to the cerebellum, occipital lobes, and brainstem, all of which have diverse functions. Berry (saccular), fusiform, and mycotic aneurysms are the three forms of cerebral aneurysms. The most frequent type, known as a "berry aneurysm," is more common in adults. It can be a few millimetres long or more than two centimetres long. If you have a family history of aneurysms, you're at a higher risk.

Cerebral aneurysms, like other forms of aneurysms, may not cause any symptoms. However, the following symptoms may occur:-

· Headache that is severe

· Above and behind the eyes, there is a lot of pain.

· Loss of feeling

· Weakness

· On one side of the face, there is paralysis.

· The pupil of the eye is dilated.

· Changes in vision or double vision

· Vomiting or nausea

· Neck stiffness

· Light sensitivity is a term used to describe a person's sensitivity to light

· Seizures

· Consciousness loss (brief or prolonged)

· Arrest of the heart

Procedures involving the endovascular system

Patients with unruptured vertebral and basilar artery aneurysms were given a dual-antiplatelet regimen (75 mg clopidogrel and 100 mg aspirin daily) for at least 3 days before the surgery. We gave a loading dose of antiplatelet medication (300 mg aspirin and 300 mg clopidogrel) orally or through a stomach tube 4 hours before the procedure to patients with ruptured vertebral and basilar artery aneurysms. The endovascular procedures were then carried out under general anaesthesia with the use of systemic heparin.

When flow diverters are used in the posterior circulation, the risk of complications is higher than when they are used in the anterior circulation. However, flow diverters in the posterior circulation have primarily been employed to treat dissecting, fusiform, and/or partly thrombosed aneurysms in the literature, making comparisons with earlier series problematic. Because clipping vertebral and basilar artery aneurysms are frequently difficult, endovascular coil embolization has become popular for these aneurysms. However, because of the poor long-term stability of coiling alone to repair complex vertebral and basilar artery aneurysms, it is still contentious.

Bilateral Varicocele Embolization

Image
Varicoceles are not life-threatening, however, they can be linked to serious illnesses in rare cases. If a varicocele arises on the right side of the abdomen rather than the left, for example, make sure there is no mass or other abnormalities in the abdomen that could be causing it. Blood is transported back to the heart via veins throughout the body. They usually feature valves to keep the blood flowing in the right way. When the valves in the testicular vein don't work properly, blood can pool in the scrotum, resulting in a varicocele. They commonly happen on the left side, and they're caused by the testicular vein's path through the abdomen. Varicocele is a frequent condition that is not hazardous. In fact, a varicocele affects 15% of all adult men. Many men's varicocele will go undiscovered for the rest of their lives or may create no complications at all. Varicoceles affect about 20% of teens, therefore a portion of them will most likely resolve on their own. The

LIVER ABSCESS DRAINAGE

Image
A pus-filled patch of fluid within the liver is known as a pyrogenic hepatic abscess. Pyogenic denotes the production of pus. A liver abscess can arise from a number of various causes, including a blood infection, an abdominal infection, or an infected abdominal injury. An abscess in the liver is a serious infection. It has the potential to cause major issues and even death. It can cause tissue damage in the spot where it is discovered. Fever, discomfort, nausea, diarrhoea, and loss of appetite are all possible symptoms. The whole first treatment for an amebic liver abscess is amebicidal medicines. The medication of choice is metronidazeole. The size of the abscess is a key determinant in deciding how well medical therapy works. Other treatment options include percutaneous needle aspiration and/or catheter drainage.  The type of abscess that occurs is influenced by one's age. People in their 40s and 60s are more likely to have a liver abscess that is not caused by trauma.  The foll

What is Interventional Radiology?

Image
  The medical technology has done so much progress in the past one decade that it’s sometimes surprising. Interventional radiology is one such amazing medical innovation that involves medical imaging which guides minimally invasive surgical procedures that help in diagnosis, treatment and cure of many different kinds of treatments. For imaging, the modalities used are ultrasound, MRI, CT and fluoroscopy. Why Interventional Radiology? Many surgeries are now being switched to the method of Interventional radiology and that is because the IR procedure is known to be more effective compared to their traditional surgical counterparts. This method is any day less risky, less painful and even costs you way lesser comparatively. These reasons are influencing people to prefer the IR treatment methods and hence it is starting to expand all across the world. How does Interventional Radiology work? There are various broad range procedures performed under Interventional Radiology like treating tumo
