Fifty cases comprising 11 cases of disseminated intravascular coagulation (DIC), 16 cases of venous thromboses and 23 cases of hepatic diseases were studied for AT III levels using clotting assay. Twelve samples were subjected to ATIII estimation by the commercially available synthetic chromogenic assay. Twenty age and sex matched controls were also analysed to find out the reference value for the techniques. Low AT III levels, if present, were correlated with other markers of DIC, viz FDP and D-dimer assays. There was a decrease in the AT III levels in all the three disease categories with a significant difference between the AT III levels of the three disease categories. In DIC, lowest levels were observed which correlated well with FDP and D-dimer levels. There was no significant difference between the average AT III levels measured by both the clotting and synthetic chromogenic assay with the former procedure being relatively inexpensive.

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
