Aneurysm Flow Diverter Treatment

What does flow diversion entail?

What does flow diversion entail?

Instead of inserting a device inside the aneurysm sac, as with coiling, a flow diversion device is placed in the parent blood artery to divert blood flow away from the aneurysm.

 What is the procedure for flow diversion/Pipeline?

  1. Slide for flow diversion
  2. The Pipeline stent is being inserted.

A microcatheter is steered through the aneurysm without needing to enter it during a flow-diversion/Pipeline treatment. Then, in the parent blood vessel where the aneurysm is situated, the flow-diverting device (Pipeline Embolization Device) is deployed across the neck of the aneurysm.

The blood flow to the aneurysm is reduced almost immediately, and the aneurysm closes completely between 6 weeks and 6 months after the treatment. Reasons for performing flow diversion

An unruptured brain aneurysm may be treated using a flow diversion technique. Flow diversion is one way for avoiding the most risky phase of endovascular aneurysm treatment: entering the aneurysm. By not putting a device into the aneurysm, the chance of it rupturing during surgery is considerably reduced.  For wide-necked side-wall aneurysms, flow diverters are employed to provide a curative endovascular therapy option. 1–4 The majority of the high-quality data available for these devices comes from the treatment of large and enormous aneurysms. The flow of blood from the parent artery into the aneurysm is disrupted by a flow-diverter stent, which gradually slows the flow of blood into the aneurysm and, over time, prevents blood from entering the aneurysm altogether. 

Doctors do not need to operate on the aneurysm during flow diversion. Doctors doing this procedure include:

To observe your blood vessels clearly, use modern imaging technologies and radioactive contrast dye.

Pass a catheter through your blood vessels until it reaches the aneurysm's location.

The flow of blood from the parent artery into the aneurysm is disrupted by a flow-diverter stent, which gradually slows the flow of blood into the aneurysm and, over time, prevents blood from entering the aneurysm altogether.

Place a stent, a small, clever device, in the parent blood vessel of the aneurysm, where the aneurysm developed, with care. This redirects blood flow away from the aneurysm, guaranteeing that it is no longer a threat to your health.

 BEFORE FLOW DIVERSION

    


 

Blood flows freely into the aneurysm.

FLOW DIVERSION TECHNIQUE


 

After treatment with Pipeline Flex, blood flow into the aneurysm slows. Over time, blood may no longer flow into the aneurysm.

AFTER FLOW DIVERSION

What are the possible side effects of endovascular coiling?

 · Consciousness loss.

· Transient ischemic attack (TIA) or stroke (TIA, a temporary stroke-like condition)

· One-half of the body is paralysed.

· Clot of blood.

· Bleeding.

· A swollen region caused by a blood collection (hematoma)

Sudden dizziness, impaired vision, and seizures are all indications of a brain aneurysm. Some people experience nausea, vomit, confusion, or drooping eyelids (further symptoms of a stroke are also possible)

Medical applications:- Flow diverters are an alternative to endosaccular coil embolization for cerebral aneurysms (although the two methods can be used together, especially in large/giant aneurysms). It is most successful in unrupted saccular aneurysms with a large neck that are difficult to coil due to the coils' tendency to fill the parent artery (referred to as prolapse). Fusiform shape or circumferential aneurysms are another scenario. Many intracranial aneurysms went untreated before flow diverters were invented.

What are the hazards and complications of installing a flow diverter?

With the advancement of technology, the complication rate is now less than 5% in expert hands. Hematoma (blood clot in the groyne), hemorrhagic or ischemic stroke (small or large) are all possible complications. However, in most circumstances, these can be prevented with good procedure planning, device selection, and post-procedure care.

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
