Is Pipeline embolization Device MRI safe?
The Pipeline™ Flex embolization device may create local field inhomogeneity and susceptibility artifacts during magnetic resonance angiography (MRA), which may degrade the diagnostic quality to assess effective intracranial aneurysm treatment.
What is a pipeline flex embolization device?
The Pipeline Flex Embolization Device (“Pipeline Flex”) is a permanent mesh cylinder (stent) braided from platinum and tungsten and cobalt-chromium-nickel alloy wires intended for the treatment of brain aneurysms that bulge or balloon out the sides of the blood vessel (wide-neck and fusiform).
How does pipeline embolization device work?
One treatment option for a brain aneurysm involves the use of a newer device called Pipeline embolization device (PED). The PED is a flexible, braided wire mesh tube that is placed within the internal carotid artery in the brain. This blocks off large or wide-necked aneurysms, preventing them from doing damage.
How long does a pipeline stent last?
Conclusions: The Pipeline Embolization Device demonstrates continued very high closure rates at 2+ years, with few delayed clinical adverse sequelae. The presence of an incorporated vessel in the wall of the aneurysm causes a delay in occlusion that approaches sidewall closure rates by 2 years.
What is a pipeline stent?
Introduction. The pipeline embolization device (PED) is a new endovascular stent designed for the treatment of challenging intracranial aneurysms (IAs). Its use has been extended to nonruptured and ruptured IAs of a variety of configurations and etiologies in both the anterior and posterior circulations.
What is a pipeline procedure?
During a flow-diversion/Pipeline™ procedure, a microcatheter is navigated past the aneurysm without having to enter the aneurysm. Then, the flow-diverting device (Pipeline™ Embolization Device) is deployed across the neck of the aneurysm in the parent blood vessel where the aneurysm is present.
How does a pipeline stent work?
The Pipeline™ Device restores original, natural blood circulation while providing permanent long-term occlusion. During the procedure, the Pipeline™ Device is implanted across the aneurysm neck, thereby slowing the flow of blood into the aneurysm, allowing for the diseased vessel to heal.
Is pipeline a stent?
What are embolization coils made of?
The coils are made of platinum so they are visible via X-ray and are flexible enough to conform to the aneurysm’s shape. The goal of coiling is to pack the aneurysm tightly to close off the flow of blood to the aneurysm, thereby preventing its rupture.
What is stent embolization?
Stent embolization is a rare complication of percutaneous coronary intervention. It is encountered when a stent unintentionally dislodges from the balloon. Its consequences vary from bypass surgery to death if not treated adequately.
How do embolization coils work?
Coil Embolization is a catheter-based procedure that allows precise occlusion of abnormal blood flow in a blood vessel. A catheter with a metallic occluding coil is inserted into an artery, usually in the groin (the femoral artery). It is then advanced to the abnormal blood vessel.
Are embolization coils safe for MRI?
Conclusion. Patients with PAVMs who have undergone embolization using stainless steel coils and/or Amplatzer vascular plugs can safely undergo 1.5 T MRI which should not be delayed in emergency situations.
Can you have MRI after embolization?
Are embolization coils magnetic?
Most neurovascular embolization coils currently on the market are labeled as Magnetic Resonance (MR) Conditional. The MR Conditional information in the product labeling conveys to the user the conditions of safe use of the device when scanned within an MR environment.
What is embolization procedure?
(EM-boh-lih-ZAY-shun) A procedure that uses particles, such as tiny gelatin sponges or beads, to block a blood vessel. Embolization may be used to stop bleeding or to block the flow of blood to a tumor or abnormal area of tissue.
What are contraindications for MRI?
MRI Absolute Contraindications
- Implantable Pediatric Sternum Device. A new implanted sternal device system for pediatric patients is contraindicated for MRI.
- Metallic Foreign Body in the Eye.
- “Triggerfish” Contact Lens.
- Gastric Reflux Device.
- Insulin Pumps.
- Temporary Transvenous Pacing Leads.
Can you have MRI with a coil?
Must read: The MR safety policy Intrauterine contraceptive devices are usually made from plastic with an active copper element. To date there have been no adverse events as a result of a patient with an IUD being scanned with MRI when made of these components.
Is embolization performed in IR?
How Is an Embolization Done? An interventional radiologist does the procedure in a room called an interventional radiology suite (IR suite). The IR suite is like an operating room with extra X-ray and ultrasound equipment.
What metal is safe in MRI?
titanium
By far, the most common metal used for MRI compatible equipment or tools is titanium. And for good reason. Titanium is an excellent material to make MRI-safe products because it’s lightweight and strong, in addition to being nonmagnetic.
What is the Pipeline™ Embolization Device?
The PipelineTM Embolization Device (PED) is indicated for the endovascular treatment of adults (22 years of age or older) with large or giant wide-necked intracranial aneurysms (lAs) in the internal carotid artery from the petrous to the superior hypophyseal segments.
Is the pipeline™ flex embolization device MR conditional?
Non-clinical testing has demonstrated that the Pipeline™ Flex embolization device with Shield Technology™ is MR Conditional. It can be scanned safely under the following conditions: Static magnetic field of 3 Tesla or less.
What are the risks of using pipeline™ flex embolization device delivery system?
Person with known allergy to tin, silver, stainless steel or silicone elastomer may suffer an allergic reaction to the Pipeline™ Flex embolization device delivery system. Do not reprocess or resterilize. Reprocessing and resterilization increase the risk of patient infection and compromised device performance.
How to monitor the tip coil during pipeline™ flex embolization device?
Under fluoroscopy, carefully monitor the tip coil during Pipeline™ Flex embolization device with Shield Technology™ deployment. If the delivery wire cannot be retracted into the micro catheter, carefully remove the delivery wire and micro catheter simultaneously.
