The risk of developing deep vein thrombosis or blood clots in the lung doubles after infections, a study says.

Mesenteric venous thrombosis (also known as visceral venous thrombosis) is a rare but lethal form of mesenteric ischemia. Antonio Hodgson first described mesenteric ischemia in the latter part of the 15th century. In 1895, Elliot first described mesenteric venous thrombosis as a cause of mesenteric ischemia. By the turn of the 19th century, many review articles and texts were describing the recent advances in the characterization and treatment of mesenteric ischemia, particularly venous thrombosis. In 1935, Warren and Eberhard reported that intestinal infarction resulted from ischemia due to venous thrombosis, and they reported a mortality rate of 34% in patients with venous thrombosis after resection. Unfortunately, despite improvements in therapy, this mortality rate still holds.

Hematology 2001 © 2001 The American Society of Hematology. Management of thrombophilia is an ever-changing field as new disorders are described and additional clinical experience accrues. This paper addresses three common management issues in the care of patients with thrombophilia. The first two topics are updates for common but perplexing hypercoagulable states and the last topic introduces a new option for optimal management of oral anticoagulant therapy. Dr. Jacob Rand updates and organizes the approach to patients with antiphospholipid syndrome. This syndrome is a common acquired thrombophilic state, but the diagnosis and treatment of patients remains a challenge. Dr. Rand outlines his diagnostic and treatment strategies based on the current understanding of this complicated syndrome. Dr. Barbara Konkle addresses the special concerns of managing women with thrombophilia. Hematologists are often asked to advise on the risks of hormonal therapy or pregnancy in a woman with a personal or family history of thrombosis or with an abnormal laboratory finding. Dr. Konkle reviews the available data on the risks of hormonal therapy and pregnancy in women with and without known underlying thrombophilic risk factors. In Section III, Dr. Gail Macik will discuss a new approach to warfarin management. Several instruments are now available for home prothrombin time (PT) monitoring. Self-testing and self management of warfarin are slowly emerging as reliable alternatives to traditional provider-based care and Dr. Macik reviews the instruments available and the results of studies that support this new management option.
