Stephan Moll, MD writes…..
When a young person is diagnosed with extensive pelvic DVT or inferior vena cava thrombosis, there may be an underlying and predisposing congenital abnormality of the IVC, such as a congenital absence (agenesis, aplasia) or narrowing (hypoplasia) of the IVC Read the rest of this entry »
Stephan Moll, MD writes… This month the American College of Chest Physicians (ACCP) published its new (2012) guidelines regarding anticoagulation and management of various thrombotic disorders, replacing the 2008 edition. The details of the new guidelines can be found here Read the rest of this entry »
CT or MRI scans will occasionally detect an incidental iliofemoral DVT, PE or intra-abdominal thrombosis (IVC, portal, splenic, mesenteric or renal vein). This is particularly common in cancer patients undergoing staging CT scans. When such an incidental, asymptomatic venous thromboembolism (VTE) is discovered, the question arises whether the patient should be treated with anticoagulants or not. Read the rest of this entry »
Explanation for Patients
The complex topic of “Length of Anticoagulant Treatment” for patients with VTE is being addressed in a blog entry written for patients, found on the Clot Connect patient education blog (here).

Testosterone Replacement Therapy
Replacement therapy with low doses of testosterone does not adversely affect blood coagulation status [ref 1] and does not appear to increase the risk of venous or arterial thrombosis. Thrombosis is not listed as a potential side effect in the commly used drug compendium (Micromedex). Furthermore, the 2006 “Clinical Practice Guideline” from the Endocrine Society also does not list thrombosis as a side effect of testosterone replacement therapy, or a previous history of blood clots as a reason not to give testosterone replacement therapy [ref 2]. However, the Androgel® package insert (prescribing information) lists “blood clots in the legs” as a potential side effect Read the rest of this entry »
What is HHT?
HHT (Hereditary Hemorrhagic Teleangiectasia), called Osler-Weber-Rendu syndrome, is an inherited disorder in which small blood vessels develop abnormally [ref 1]. It is estimated that 30,000 to 60,000 people (1 out 5,000 to 10,000) in the United States are affected. Individuals with HHT develop telengiectasias in the skin (usually in the fingers and hands) and the mucosa of the nose and mouth. Similar abnormal blood vessels (arterial-venous malformations, AVMs) can also develop in internal organs Read the rest of this entry »
If you as a health care professional are involved in the management of patients with acute (proximal) DVT, please consider giving the patient (who has leg symptoms ≤ 14 days) an opportunity to be enrolled in the national ATTRACT trial (information on the trial is here).
This NIH-funded, multi-center trial investigates whether catheter-directed thrombectomy (± locally delivered tPA into the clot) Read the rest of this entry »
A detailed discussion of the symptoms of and risk factors for DVT and PE, written for patients, is available on the Clot Connect Patient blog- connect here. We hope that the health care professional will find this document suitable to be printed out as a handout for patients and their family members whom they want to educate about the symptoms of and risk factors for DVT and PE.

It is well known that combination contraceptives (containing estrogens AND progestins) increase the risk for venous thromboembolism (VTE). Relatively few data, however, have been published on progestin-only contraceptives, so that until recently it was not clear whether they increase the risk for venous thromboembolism (VTE) or not.

Confusion as to which veins of arms and legs are superficial and which are deep can lead to misclassification superficial thrombophlebitis and DVT and, thus, to incorrect treatment decisions.
