IVC Filter Insertion

The inferior vena cava is the widest vein in your body. It carries blood from your lower body to your heart and lungs. In an inferior vena cava filter placement procedure, interventional radiologists use image guidance to place a filter in the inferior vena cava (IVC), the large vein in the abdomen that returns blood from the lower half of the body to the heart.

Blood clots that develop in the veins of the leg or pelvis, a condition called deep vein thrombosis (DVT), occasionally break up and large pieces of the clot can travel to the lungs. An IVC filter is a small metal device that traps large clot fragments and prevents them from travelling through the vena cava vein to the heart and lungs, where they could cause severe complications such as pain, difficulty breathing, shortness of breath, or even death.

Until recently, IVC filters were available only as permanently implanted devices. Newer filters, called optionally retrievable filters, may be left in place permanently or have the option to potentially be removed from the blood vessel later. This removal may be performed when the risk of the clot travelling to the lung has passed. This should be assessed by a physician or the interventional radiologist who inserted the IVC filter sometime after placement, ideally less than six months after insertion. Removing an IVC filter eliminates any long-term risks of filter fracture or recurrent DVT. However, it does not address the cause of DVT. Your referring physician will determine if blood thinners are still necessary. Not all retrievable IVC filters should be removed if the risk of clots travelling to the lung persists and if blood thinners continue to be unusable. These filters can be left in place as permanent filters, but many filters can be removed even after being in place for several years.


What are some common uses of the procedure?

Inferior vena cava (IVC) filters are placed in patients who have a history of or are at risk of developing blood clots in the legs, including patients:

  • diagnosed with deep vein thrombosis (DVT).

  • with pulmonary embolism.

  • trauma victims'

IVC filters are used when patients cannot be successfully treated by other methods, including blood thinning agents

Subcutaneous implantable cardioverter-defibrillator

Image
  A subcutaneous implantable cardioverter-defibrillator (S-ICD) is a type of defibrillator that is implanted under the skin on the chest. Unlike traditional implantable cardioverter-defibrillators (ICDs), which are implanted in the chest with wires inserted into the heart, the S-ICD system is implanted under the skin and does not require any wires to be inserted into the heart. The S-ICD system includes a pulse generator that is implanted under the skin on the left side of the chest, and a lead that is placed under the skin and runs along the left side of the breastbone. The lead senses the heart's electrical activity and delivers a shock to the heart if it detects a life-threatening rhythm. S-ICD s are typically used in patients who are at risk for sudden cardiac death due to a high risk of ventricular arrhythmias, but who do not have a need for pacing therapy. S-ICDs are an alternative to traditional ICDs and can be useful in patients who are unable to tolerate a trans venous IC...

Permanent Pacemaker

Image
  Pacemakers can be defined as devices that are placed in your body by surgery to support the electrical system in your heart. It is generally used to stabilize abnormal heart rhythms and prevent life dangering or disrupting chances. Single-chamber pacemakers use a single wire attached to one chamber of your heart, whereas Dual-chamber pacemakers use two wires.  A pulse generator is a small metal case that contains an electronic circuit with a small computer and battery that regulates the pulses sent to the heart. A lead is an insulated wire that connects to the pulse generator at one end and is placed in one of the heart chambers at the other end. Leads are most often placed through large veins in the chest that lead directly to the heart. An electrode at the tip of the lead contacts the heart wall. The leads send electrical impulses to the heart. It also senses the heart's electrical activity and sends that information back to the pulse generator. Pacing leads are placed in...

HEAD AND NECK CANCER

Image
  Head and Neck Cancer  is begin with the squamous cells which line the mucosal surface of the Head and Neck area. Likewise inside the mouth, voice box, throat, and other parts of the salivary gland, sinuses, muscles, and nerves in the head and neck. Cancers like the brain, thyroid gland, eyes, and skin of the head and neck area are not considered Head and Neck Cancer. If the squamous cells of carcinoma of the head and neck area are spreading, it can harm the crucial part of the head and neck part. The cancerous cells in lymph nodes are found in the upper neck when such evidence of cancer is not found in other parts of the area because the actual primary tumor is comparatively small. SYMPTOMS A lump in the neck, a sore that won’t go away and may hurt, a sore throat that won’t go away, trouble swallowing, a change in voice quality, or hoarseness are all possible signs of head and neck cancer. Other, less serious illnesses may also be at blame for these symptoms. Any of these sy...
