Elevated D-dimer level in the differential diagnosis of venous malformations.

To evaluate if elevated D-dimer level is specific for venous malformations (VMs) and thus useful for differential diagnosis, which can be problematic even in specialized interdisciplinary centers. Localized intravascular coagulopathy, characterized by elevated D-dimer levels, has been observed in approximately 40% of patients with VMs.


Prospective convenience sample accrued from 2 interdisciplinary sites.


Two interdisciplinary centers for vascular anomalies in Brussels, Belgium, and Caen, France


The study population comprised 280 patients with clinical data, Doppler ultrasonograms (for 251 patients), and coagulation parameter measurements. Main Outcome Measure Measurement of D-dimer levels.


A VM was diagnosed in 195 of 280 patients (69.6%), and 83 of them had elevated D-dimer levels; the sensitivity of D-dimer dosage was 42.6% (95% confidence interval, 35.6%-49.5%). Among the 85 patients without VM, D-dimer levels were elevated only in 3 patients; the specificity of the dosage was 96.5% (95% confidence interval, 92.5%-100%).


Elevated D-dimer level is highly specific for VMs (pure, combined, or syndromic), and therefore this easy and inexpensive biomarker test should become part of the clinical evaluation of vascular anomalies. It can detect hidden VMs and help differentiate glomuvenous malformation (normal D-dimer levels) from other multifocal venous lesions. Elevated D-dimer level also differentiates a VM from a lymphatic malformation. Moreover, slow-flow Klippel-Trenaunay syndrome (capillaro-lymphatico-venous malformation with limb hypertrophy) can be distinguished from fast-flow Parkes Weber syndrome (capillary malformation with underlying multiple microfistulas and limb hypertrophy). For these reasons, D-dimer level measurement is a useful complementary tool for diagnosing vascular anomalies in everyday practice.
