ABSTRACT
Most patients with severe motor and intellectual disabilities (SMID) have restricted mobility capability and have been bedridden for long periods because of paralysis of the extremities caused by abnormal muscular tonicity due to cerebral palsy and developmental disabilities. Such patients are associated with a high risk of complications like deep vein thrombosis (DVT). Here, we report twelve patients (42.9%) with DVT among 28 patients with SMID during prolonged bed rest. However, we did not detect thrombosis in the soleal veins, finding it mostly in the femoral and common femoral veins. We applied anticoagulant therapy (warfarin), and carefully followed up the cases with DVT, regulating the warfarin dosage at prothrombin time-international normalized ratio (PT-INR) values around two to prevent recurrence of chronic thrombosis. Regarding laboratory data for the coagulation system, there were no cases above 5 µg/ml for the D-dimer and there were significant differences between the DVT and non-DVT groups in the D-dimer levels. The plasma levels of D-dimer in patients with DVT diminished to less than 1.0 µg/ml after warfarin treatment. Concerning sudden death (4.2%) in patients with SMID, we have to be very careful of the possibility of pulmonary thromboembolism due to DVT. Therefore, we should consider the particularity of the underdeveloped vascular system from underlying diseases for the evaluation of DVT. A detailed study of DVT as a vascular complication is very important for the smooth medical care of SMID, and serial assessment of compression Doppler ultrasonography of the lower extremities, as a noninvasive examination and measurement of D-dimer, is very helpful.
