Abstract:
The evaluation of coagulopathies can be challenging due to the extensive variety of etiologies. This can be particularly complicated in patients with concomitant autoimmune disorders. In this case, a 64-year-old woman presented with intractable headaches and neck pain for two weeks. Her coagulation tests revealed an isolated prolongation of activated partial thromboplastin time (aPTT). This case highlights the diagnostic approach and summarizes management considerations in patients with similar presentations.

Introduction to Hemostasis
The three phases of hemostasis involve many clotting factors present in plasma and several substances released by platelets and injured tissue cells. It is a fast, localized,...

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
