Stephan Moll, MD writes… An article for patients discussing (a) IVC filters (inferior vena cava filters; also often referred to as “Greenfield filters”), (b) narrowing of the main left pelvic vein (referred to as May-Thurner syndrome) and (c) stents in veins in the pelvis has just been published (http://circ.ahajournals.org/content/133/6/e383.full.pdf). Color images are included helping explain what these conditions are.

Stephan Moll, MD writes… A clinical research study is being conducted in the U.S. for the treatment of chronic deep vein thrombosis (DVT) with post-thrombotic syndrome (PTS) and is open for enrollment. It is referred to as ACCESS-PTS. Read the rest of this entry »
Stephan Moll, MD writes (Dec 17, 2014)… The American Society of Hematology (ASH) published last week two things that physicians dealing with DVT, PE and blood thinners should avoid [ref 1]. Read the rest of this entry »
Stephan Moll, MD writes… Patients with cancer may have catheters in veins in their upper chest, neck or arm (central venous catheter, port), to enable chemotherapy, fluids or blood products to be given. These catheters increase a patient’s risk for developing an arm or neck clot (DVT) leading to arm or neck swelling, pain, and may be warmth and reddish discoloration. Typically, blood thinners are used in this situation to prevent the clot from getting bigger or breaking off and traveling to the lung to cause a lung clot (pulmonary embolism; PE). Limited data exist how to best manage these catheter-associated DVTs.
This week (Feb 18th, 2014) a guidance document on the prevention and management of catheter-associated upper extremity and neck DVT was published by one of the respected medical societies (International Society for Thrombosis and Haemostasis; ISTH) [ref 1].
A summary of the conclusions and treatment recommendations for health care professionals has been published on Clot Connect here.

An important study (called AMPLIFY trial) was published today in the New England Journal of Medicine [ref 1]. In a large study of patients with acute DVT or PE, Eliquis (apixaban) was as effective as warfarin and caused less major bleeding. Read the rest of this entry »

If you’ve experienced deep vein thrombosis (DVT) or pulmonary embolism (PE), a recurrence of a blood clot in the future is a concern. Diagnosing a recurrent clot can be a challenge because it is sometimes difficult to tell if symptoms are the result of a new clot or the signs of chronic damage from the initial clot.
- Around 40% of patients with DVT develop long-term pain and swelling, known as post-thrombotic syndrome. Such pain and swelling can fluctuate, and be particularly pronounced after standing for prolonged periods of time or being overly active.
- Around 4% of patients with PE develop long-term shortness of breath, known as pulmonary hypertension.
How do healthcare professionals know when symptoms are the result of a past blood clot or due to a new clot? Read the rest of this entry »
This post begins the first in a series addressing the most commonly asked questions by patients.
“When will my clot and pain go away?” is a question commonly asked following diagnosis of deep vein thrombosis (DVT) or pulmonary embolism (PE). Read the rest of this entry »

Ischemic colitis is an uncommon disorder. It is typically not dangerous and resolves without treatment. For mostly unclear reasons multiple small or tiny blood vessels in the wall of the intestine (the large intestine = colon) have decreased blood flow or become blocked by small blood clots. This results in a lack of blood flow and oxygen delivery (ischemia = Latin for impaired oxygen supply) to a number of small areas of the intestinal wall. This leads patchy, superficial damage of the colon wall results. The damage areas often heal by themselves and no surgery is needed. The patient recovers spontaneously within a week or two. Often people have only one episode. Few people have two or more bouts. Read the rest of this entry »
Stephan Moll, MD writes… An important study was published on May 23rd, 2012 in the New England Journal of Medicine [ref 1], showing that aspirin decreases the risk of recurrent clots (DVT and PE) in patients who have had a previous unprovoked (= idiopathic) clot and who have completed 6 to 18 months of blood thinner therapy. Aspirin did not lead to an apparent increase in risk of major bleeding Read the rest of this entry »
