Radical treatment of primary type B aortic dissection or after thoracic endovascular aortic repair to manage disseminated intravascular coagulation.

Disseminated intravascular coagulation (DIC) secondary to type B aortic dissection is an unusual and fatal complication that has not been fully investigated. The aim of our study is to report a novel endovascular technique excluding all tears to manage DIC. From April 2017 to October 2017, we performed 2 cases of DIC complicated to type B aortic dissection using this novel radical endovascular repair technique. Clinical data of patients were collected and technical details were presented. These two cases were successfully treated with novel radical endovascular repair technique. DIC was managed and FL thrombosis was formed in these two patients. Follow-up at 6 months revealed no recurrent DIC and a stable aortic diameter with complete FL thrombosis. This endovascular repair technique that excluding all the tears is a feasible approach to prevents continuous coagulation components consumption and thus to manage DIC effectively.
