Removing Blood Clots From Lungs With Surgery – As many as 900,000 people in the United States are affected by deep vein thrombosis (DVT) and/or pulmonary embolism (PE) each year, with a higher death rate than breast cancer, car accidents, and HIV combined. Until recently, treatment options for these life-threatening conditions were limited to muscle-melting drugs, filters to catch disintegrating stones, or invasive surgeries that carry their own risks. Fortunately, there’s another option and it’s right in our backyard.
Sentara Norfolk General Hospital is the first healthcare facility in the region to offer a new, minimally invasive procedure for removing blood clots using a blood vacuum, called AngioVac. This procedure is not a typical game changer: it is a major step forward in reversing life-threatening conditions while minimizing the health effects of procedures such as open heart surgery.
Removing Blood Clots From Lungs With Surgery
Dr. David Dexter, a vascular surgeon at Chintra who has performed this procedure on more than 50 patients to date, explains that the analogy to a vacuum is spot on, as the clot is drawn from the body. According to him, the ability to move large amounts of blood out of the body, filter it and return to the body, It is a tool to prevent significant blood loss.
Pulmonary Embolism: Causes, Symptoms & Treatment
Due to the level of multidisciplinary professionals required, this new procedure is not “something patients can walk into a doctor and ask for.” Dexter said he hopes the local medical community will see that this is not competition with open heart surgery, but a new option in their work with patients suffering from vascular disorders, as 50 percent will occur within 10 years.
Sentra’s optimism about the future of this technique, and its impact on patients’ quality of life, was loud and clear when Dexter talked about the continued improvement in his work. His team has already seen procedure times from six hours to one hour.
The procedure itself involves the insertion of thin tubes into two large veins through the neck or groin area. Under X-ray and ultrasound guidance, the tube is moved to the affected area. The tip of the catheter is attached to the circular part of the clot vacuum, then creating a bypass, allowing the blood to be filtered from the body while the clot is being removed. Once removed, the injection tube returns the filtered blood to the body, greatly reducing blood loss.
As with any medical procedure, some patients are more suitable for this intervention than others. Consideration of the nature of the muscle, its location, the attachment of the surrounding tissue and existing health conditions are among the determining factors. Dexter’s advice to patients who may be experiencing DVT/PE is to discuss their risk factors with their doctor and see what treatment options are available.
A Simple And Effective Method For Bladder Blood Clot Evacuation Using Hydrogen Peroxide
Dexter successfully removed the stone from the heart’s right atrium, inferior vena cava, and superior vena cava, as well as the iliac vein. He was also the first in the country to use this new technology to remove blood from the right ventricle of a pediatric patient. These are not just game changers, these are the wonders of modern medicine.
Unlike more invasive measures, there are no restrictions on activity after the procedure. Dexter notes that he wants his patients to “get up and walk as fast as possible.” This can get the patient rid of the blood clot and back to work within two days.
When asked about common candidates for the procedure, Dexter noted that a common factor among those he works with is failure of other methods to remove the clot and therefore, aspiration of the clot is “an option of last resort.” His team’s ability to remove life-threatening stones that are unresponsive to blood pressure, clogged filters, and multiple areas of the body gives DVT/PE sufferers more hope.

A blood clot that blocks or slows blood flow to the brain can lead to a stroke. Thanks to modern imaging technology, a minimally invasive procedure has been developed to remove stones from the brain and other parts of the body: mechanical surgery.
Types Of Blood Clots And What They Mean
Is a type of minimally invasive procedure in which radiologists use special equipment to remove blood clots from a patient’s blood vessels. to use
, or a continuous X-ray, the doctor guides the device through the patient’s artery to the blockage, and removes the stone in one stroke.
The radiologist begins the procedure by making a small incision in the wrist or abdomen, giving them access to the arteries. After the surgery, the doctor will insert a catheter to drain the blood into the artery. Next, they put a small net-like device called a
Insert the catheter and guide it to the blockage. Then they push the stent retriever through the clot.

After the stent retriever is passed, it expands to the size of the artery wall. At this point, the stent retriever has caught the clot, and the doctor can pull it out, removing the entire clot.
This procedure is used to treat blockages in arteries caused by blood clots. The following conditions can be treated by mechanical thrombectomy:
Deep vein thrombosis (DVT) – a blood clot that forms in an artery. DVTs most often occur in the legs, but they can also occur in the arms. DVT can cause permanent damage to valves within blood vessels. This can cause long-term foot problems such as pain, swelling and foot ulcers. DVTs are also dangerous because of the possibility that the clot can break off and travel to the lungs. If this happens, the clot can block blood flow and cause a blood clot in the lungs, which can be fatal.
Ischemic stroke- a blood clot formed in an artery leading to the brain, or in an artery in another part of the body leading to the brain. This causes the blood supply to the brain to stop or slow down. Within minutes, permanent brain damage is possible.

Studies have shown that patients with mechanical thrombectomy recover faster and have a better quality of life compared to patients using anticoagulant tPAs (or.
However, like all medical procedures, mechanical thrombectomy is not for everyone. In an emergency, know that if tPA is insufficient to treat the clot, mechanical surgery is an available option.
At the University of Virginia Health System, we have interventional neuroradiologists who are specially trained to perform mechanical thrombiectomies. If you or a loved one is at high risk for stroke, make sure you know the warning signs. If possible, choose a stroke medical center, such as the University of Virginia, where various stroke treatments, including mechanical surgeries, are available.
Mechanical Thrombectomy: A New, Minimally Invasive Treatment for Clogged Arteries Last Updated: December 19, 2019 by UVA Radiology Jeffrey Polk, MD, has seen many incremental changes over the years, but few game-changers.
These Are Blood Clots That I Removed From The Lungs [airways] Of A Patient With Covid 19.
Robert I. White Jr. Professor of Radiology and Biomedical Imaging at Yale School of Medicine (YSM) Polk had a game-changing moment earlier this year while performing a minimally invasive procedure on a patient with a life-threatening pulmonary embolism. .
Through a small incision in the skin, Polk guided a catheter into the pulmonary artery leading to the stroke. As he removes the catheter, he uses a suction device to pull the clot out of the artery and then out of the patient entirely through an incision in the skin.
“You can see patients, who are almost unable to breathe, come back to life on the table because the blood clot is removed,” said Hamid Mojibian, MD, professor of radiology and biomedical imaging at YSM who performs interventional radiology (IR) procedures. With Polk .
Kevin Kim, MD, professor of radiology and biomedical imaging at YSM and head of the IR said, “The tube surgery puts the patient right on the table, even before recovery,” said Kevin Kim, MD, professor of radiology and biomedical imaging at YSM and head of IR.

The main advantage of the IR process is that it does not require the use of clot-busting agents that can cause bleeding elsewhere in the body, Polk said. “It expands our ability to treat older patients, or patients with other medical conditions who are at higher risk of bleeding,” he said.
Radiologists at YSM are the first in Connecticut and among the first in the Northeast to successfully perform a pneumonectomy with a new mechanical device that does not require chemotherapy or vascular surgery.
“With this new, innovative and successful treatment, we can cure people,” said Kim, our critically ill patients with pulmonary embolism safely and effectively, and help the lives of more people.
In the past, patients with pulmonary embolism would spend 6 to 12 hours receiving thrombolytics, usually staying in the intensive care unit for one to two days. “If
