Acquired von willebrand disease hypothyroidism in children – Acquired von Willebrand’s syndrome caused by primary hypothyroidism in a 5-year-old girl

It has been recommended that perioperative management or treatment of bleeding complications in AVWS associated with valproic acid therapy should use VWF concentrates only, because DDAVP may increase the risk of seizures in these patients.

Acquired von willebrand disease hypothyroidism in children of AVWS. Blood ; 12 : — DDAVP and replacement of VWF may reduce bleeding symptoms in children with high shear stress lesions and reduced levels of high-molecular-weight multimers. The best-studied cause of AVWS in childhood is increased shear stress from congenital heart lesions. However, prophylactic DDAVP should be considered prior to thyroid biopsy or other surgery in these patients prior to correction of the thyroid hormone deficiency. In a double-blind, placebo-controlled trial, DDAVP was shown to reduce bleeding in adults undergoing aortic valve replacement for aortic stenosis, 32 although only a small subset of these patients had proven AVWS. A quality assessment was performed for clinical epidemiological studies.
