Abstract

Background
Deep vein thrombosis (DVT) and pulmonary thromboembolism (PTE) are major complications of spinal cord disease. However, studies of their incidence in Korean patients are limited. Thus, this study investigated the incidence and risk factors of DVT and PTE in Korean patients with spinal cord disease.
Methods
We retrospectively analyzed the medical records of 271 patients with spinal cord disease who were admitted to a rehabilitation unit within 3 months of disease onset at a tertiary hospital. The presence of DVT and PTE was mainly determined using Doppler ultrasonography and chest embolism computed tomography. Risk factor analysis included variables such as sex, age, obesity, completeness of motor paralysis, neurological level of injury, cause of injury, lower extremity fracture, active cancer, and functional ambulation category (FAC) score.
Results
The incidences of DVT and PTE in the patients with spinal cord disease were both 6.3%. Risk factor analysis revealed that age of ≥65 years (p=0.031) and FAC score of ≤1 (p=0.023) were significantly associated with DVT development. Traumatic cause of injury (p=0.028) and DVT (p<0.001) were significant risk factors of PTE.
Conclusion
Patients with spinal cord disease developed DVT and PTE within 3 months of disease onset with incidence rates of 6.3% and 6.3%, respectively. Age of ≥65 years and an FAC of score ≤1 were risk factors for DVT. Traumatic cause of injury and DVT were risk factors for PTE. However, given the inconsistent results of previous studies, the risk factors for DVT and PTE remain inconclusive. Therefore, early screening for DVT and PTE should be performed in patients with acute-to-subacute spinal cord disease regardless of the presence or absence of these risk factors.
