Insights
This case study shows dabigatran effectively treated a teen with disseminated intravascular coagulation (DIC) linked to vascular malformations. The treatment improved clotting and reduced the need for blood transfusions.
Area of Science:
- Hematology
- Vascular Medicine
Background:
- Localized intravascular coagulopathy (LIC) is a consumptive coagulopathy complicating vascular malformations, presenting with low fibrinogen and high D-dimer.
- Disseminated intravascular coagulation (DIC) is a severe complication of LIC, leading to significant morbidity.
Purpose of the Study:
- To report a case of DIC secondary to extensive vascular malformations in a young patient.
- To evaluate the efficacy and safety of dabigatran in managing DIC associated with vascular malformations.
Main Methods:
- A 17-year-old female with extensive vascular malformations and DIC, requiring frequent red blood cell transfusions, was treated with dabigatran.
- Coagulation parameters and transfusion requirements were monitored before and after dabigatran administration.
Main Results:
- Dabigatran administration led to rapid improvement in coagulation test results.
- The patient experienced a significant reduction in red blood cell transfusion needs and tolerated dabigatran well over a seven-month follow-up period.
Conclusions:
- Dabigatran may represent a novel and effective therapeutic option for managing DIC in patients with underlying vascular malformations.
- This case highlights a potential treatment strategy for a rare but serious complication of vascular anomalies.
Abstract:
: Vascular malformation is occasionally complicated by consumptive coagulopathy, known as localized intravascular coagulopathy (LIC), which is characterized by a reduced fibrinogen level, an elevated D-dimer level and a normal platelet count. We report the case of a 17-year-old Japanese girl who presented with LIC secondary to extensive vascular malformations, whose condition had progressed to disseminated intravascular coagulation (DIC). She suddenly presented with severe anaemia, despite the absence of obvious bleeding, and she began to require regular red blood cell (RBC) transfusions. As she was suffering from paroxysmal atrial fibrillation, we treated her with dabigatran, after obtaining informed consent. Immediately after the administration of dabigatran, the results of clotting tests improved dramatically. Seven months later, she has not required any RBC transfusions, and the dabigatran treatment has been well tolerated. The present case report suggests that dabigatran may be a useful treatment option for patients with DIC associated with vascular malformations.
