Abstract
A clinical criteria devised by Wells and co-workers to diagnose deep vein thrombosis namely “Wells Criteria” has been tested in our study. This criteria has been tested in various health care settings in New Zealand and has helped to reduce the dependence on radiological investigations. AIM OF THE STUDY: 1. To test the effectiveness of Wells criteria for diagnosing deep vein thrombosis. 2. To find the associated co-morbidities causing deep vein thrombosis. METHODS: In our study the Wells criteria was tested using venous doppler ultrasound to confirm any case of deep vein thrombosis as suspected by Wells criteria. Time duration of the study was from September 2012 to November 2013. The study group included 50 cases of deep vein thrombosis as diagnosed by Wells criteria. Along with this the associated co morbid conditions in each case was also documented. RESULTS: Fifty cases of suspected deep vein thrombosis as per Wells Criteria admitted to Coimbatore Medical College Hospital were subjected to the confirmatory test of doppler venous ultrasound out of which 46 were proven to have deep vein thrombosis which amounted to 92% of cases. Higher the score more was the probability of having deep vein thrombosis. Out of the associated co morbidities analyzed surgery was found to be leading factor responsible which was amounting to 43% of cases analyzed. In this group alone 90% of the surgical cases were post caesarean section which signified the prothrombotic status of pregnant females who were in the age group of 20 and 30 years. There was also a relation between blood group and deep vein thrombosis in which 47.8% of cases had A positive blood group indicating a higher level of Von Willebrand factor, possibly a mutant variant. CONCLUSION: We can conclude that the Wells criteria is a very efficient indicator to diagnose deep vein thrombosis in our setup and to classify patients into various risk groups. Thus it would help to reduce delays in diagnosis and aids the clinician to start early treatment for deep vein thrombosis.
