Validation of the Caprini risk assessment model for venous thromboembolism in high-risk surgical patients in the background of standard prophylaxis.
We used the Caprini venous thromboembolism risk assessment score to prospectively evaluate if there was a correlation between the Caprini scores and the incidence of postoperative deep vein thrombosis (DVT) in high-risk surgical patients. A second objective was to determine whether patients at extremely high risk need a more effective prophylactic regimen. ⋯ There was a significant correlation between Caprini scores and the incidence of postoperative DVT in high-risk surgical patients. A Caprini score of ≥ 11 can identify a subgroup of patients at extremely high risk. These patients need a more effective prophylactic regimen.

Lymph proteins may access peripheral blood without entering thoracic duct in patients with lymphatic dysfunction.
The objective was to investigate the hypothesis that lymphovenous communications, which allow lymph proteins to access peripheral blood without first entering the thoracic duct, open in patients with abnormal lymphatic function. ⋯ Lymphovenous communications exist in about one-third of patients with abnormalities detected on lymphoscintigraphy. The timings of tracer arrival in the liver and lymph nodes is consistent with lymphovenous communication within lymph nodes themselves.
