Partial deletion of the αC-domain in the Fibrinogen Perth variant is associated with thrombosis, increased clot strength and delayed fibrinolysis.

Genetic fibrinogen (FGN) variants that are associated with bleeding or thrombosis may be informative about fibrin polymerisation, structure and fibrinolysis. We report a four generation family with thrombosis and heritable dysfibrinogenaemia segregating with a c.[1541delC];[=] variation in FGA (FGN-Perth).

Plasma thrombin-antithrombin complex, prothrombin fragments 1 and 2, and D-dimer levels are elevated after endovascular but not open repair of infrarenal abdominal aortic aneurysm.

Introduction: Abdominal aortic aneurysm (AAA) is associated with hypercoagulability, evidenced by increased markers of coagulation activation, including thrombin-antithrombin complex (TAT), prothrombin fragments 1 and 2 (F1+2), and D-dimer. Our aim was to compare the effect of endovascular aneurysm repair (EVAR) and open aneurysm repair (OAR) on changes in coagulation activation markers after intervention.

Methods: Consecutive patients with AAAs reaching their intervention threshold in a tertiary vascular referral unit in the United Kingdom were invited to participate.

Clot architecture is altered in abdominal aortic aneurysms and correlates with aneurysm size.

Objective: Abdominal aortic aneurysm (AAA) is characterized by widening of the aorta. Once the aneurysm exceeds 5.5 cm, there is a 10% risk of death due to rupture.
