Abstract

To assess the efficacy of surgical treatment of intra-articular knee venous malformations (VM). Between 1998 and 2010, 8 children (mean age: 12.3 y) underwent surgical resection of their vascular malformation (7 venous and 1 capillary venous) involving the knee joint. The lesion was diffuse in 6 cases and well-demarcated in 2 cases. All children were suffering from knee pain and had recurrent hemarthroses. Color-Doppler ultrasonography, magnetic resonance imaging, computed tomography scan, and blood test were performed preoperatively. Preoperative and postoperative physical examination, clinical symptoms, and orthopaedic evaluation were retrospectively reviewed. Surgery consisted in arthrotomy with total excision of the vascular malformation for the 2 well-demarcated lesions and synovectomy with squeezing of the surrounding vascular malformation for 5 diffuse lesions. One patient with an extensive venous malformation associated with severe localized intravascular coagulopathy and mild hemophilia A had undergone synovectomy by knee arthroscopy. Immediate postoperative follow-up was uneventful in 6 patients, whereas 2 patients with diffuse vascular malformation and coagulopathy suffered from postoperative hemarthroses, delaying t...Continue Reading

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
