Venography is a procedure in which an x-ray of the veins is taken after a special dye is injected into the bone marrow or veins.
In a study published in the latest issue of the journal Neurological Sciences, a team of researchers described a three-patient case series presenting with neurological manifestations after the coronavirus disease 2019 (COVID-19) vaccination, followed by a literature review, to propose hypotheses on how neurological symptoms might develop after vaccination.
Like highways, roads, and side streets, blood vessels in the human body come in different sizes, with a range of traffic-carrying capacities. These differences are critical to facilitating blood flow through tissues.
Researchers demonstrated the success of a fully implantable wireless medical device called a stentrode brain-computer interface designed to improve functional independence in patients with severe paralysis.
A first-in-human study featured in the February issue of The Journal of Nuclear Medicine reports that the novel positron emission tomography/computed tomography tracer 18F-GP1 showed excellent image quality and a high detection rate for the diagnosis of acute venous thromboembolism.
Case Western Reserve University School of Medicine has received a three-year, $1,118,556 grant from the National Heart, Lung, and Blood Institute of the National Institutes of Health to investigate a new imaging approach for diagnosing peripheral arterial disease, a common and potentially serious circulatory problem. More than 200 million people worldwide suffer from the condition.
One venous puncture, rather than two, is a safe and effective approach to intravascular ultrasound-guided inferior vena cava filter placement in critically-ill patients, a new study shows.
A single intraoperative dose of tranexamic acid is effective at reducing blood loss in patients undergoing minimally invasive total knee arthroplasty, research suggests.
ThromboGenics NV and co-development partner BioInvent International announce today the results from a Phase IIb trial comparing TB-402, a long acting anticoagulant, against rivaroxaban, an oral anticoagulant.
Researchers report that performing angioplasty (a treatment that involves temporarily inserting and blowing up a tiny balloon inside a clogged artery to help widen it) on veins in the neck and chest is safe—and may be an effective way to treat the venous abnormalities found in those with multiple sclerosis and provide symptom relief.
Following a total joint replacement, anticoagulation (blood thinning) drugs can prevent Deep Vein Thrombosis (DVT), a blood clot deep within the extremities, or a pulmonary embolism (PE), a complication that causes a blood clot to move to the lungs.
A recent study shows that pelvic imaging using computed tomography examinations are not necessary for diagnosing patients with venous thromboembolism and eliminating this exam can significantly reduce a patient's exposure to excessive radiation dose.
A just released study on the relationship between multiple sclerosis and chronic cerebral venous insufficiency, a narrowing of the extracranial veins that restricts the normal outflow of blood from the brain, found that CCSVI may be a result of MS, not a cause.
Over $2.4 million has been committed by the National MS Society (USA) and the MS Society of Canada to support 7 new research projects focusing on the role of CCSVI in MS.
Gastric varices (GV) are an important complication of portal hypertension. As an almost atraumatic method, computed tomography (CT) angiography has been used widely to show the portal vein system. However, the collateral circulation of GV in different locations has been reported only rarely.
The largest study ever to examine the preventive use of blood-thinning medication to help prevent deadly blood clots in patients with cancer undergoing chemotherapy presented December 7 during the 50th Annual Meeting of the American Society of Hematology in San Francisco, CA.
The female patient, reported on the December 7 issue 45 of World J Gastroenterology, presented a rare case, with symptoms consistent with hyperadrenocorticism and hypercatecholaminism, and also had a Cushingoid appearance.
Researchers found that indirect CT venography (CTV) could identify blood clots in the legs that have the potential to break free, travel to the lung and block an artery--a life-threatening condition known as pulmonary embolism.
Researchers have new insights into a mysterious type of amnesia, according to a study published in the June 22 issue of Neurology
