Abstract

d-dimer measurement is a useful complementary initial diagnostic marker in patients with acute aortic dissection (AAD). However, it has not been clarified whether serial measurements of d-dimer are useful during in-hospital management of Stanford type B AAD. We studied 30 patients who were admitted with diagnosis of Stanford type B AAD and treated conservatively. d-dimer was serially measured on admission and then every 5 days during hospitalization. Patients were divided into two groups according to the presence or absence of re-elevation of d-dimer during hospitalization, in which d-dimer transition were biphasic and latter peak >10.0 μg/ml. Re-elevation of d-dimer was observed in 17 patients. There were no differences in atherosclerotic risk factors, blood pressure on admission, d-dimer level on admission, extent of AAD, and false lumen patency. Patients with re-elevation of d-dimer showed higher incidence of re-dissection and/or venous thromboembolism (VTE). Peak d-dimer level in patients with re-dissection and/or VTE was significantly higher than that without these complications (p = 0.005). In conclusion, serial measurements of d-dimer are useful for early detection of re-dissection or VTE in patients with Stanford type B AAD, which may contribute to the prevention of disastrous consequences such as pulmonary embolism and extension of AAD.
