Abstract Number: PO120
Meeting: ISTH 2021 Congress
Background: Venous thromboembolism (VTE) poses significant public health challenges as it is responsible for a high morbidity and mortality worldwide. Risk factors (modifiable and non-modifiable) can be identified and play a major role in its pathogenesis. Considering the cost of managing VTE in poor resource settings such as found in Nigeria, VTE risk factor identification and thromboprophylaxis will reduce the burden of disease and its treatment cost.
Aims: The study aimed to review the pattern of presentation, and risk factors, in patients diagnosed with VTE at the University College Hospital (UCH), Ibadan.
Methods: This is a retrospective study of the hospital records of 65 confirmed VTE patients (doppler ultrasound scan for DVT and CT-angiography for PE) diagnosed and managed at UCH, Ibadan between July 2016 and December 2017. Demographic data and possible risk factors documented in the case note were retrieved. The patients were treated for 3 to 6 months based on the type of VTE. Microsoft excel version 2013 was employed for carrying out the statistical analysis.
Results: 65 patients were studied of which 27 were males and 38 females (M: F=1:1.4). Their age ranged between 15 and 87 years with a mean age of 51±17 years. Only 6 patients (9.4%) were <30 years; 44.6% were between 30-50 years, and 46% were >50 years. 53 patients (81.5%) had DVT of which 65% were unilateral and 16.9% bilateral DVT. Immobilization, found in 32.3% of the patients, was the most frequently identified risk factor, followed by a prior diagnosis of malignancy (15.4%) and the use of femoral cannulation for haemodialysis (12.3%).
Conclusions: All cases of DVT (bilateral for example) should be fully screened to exclude malignancy. Prolonged immobilization should be avoided and prevented using physiotherapy and prophylactic anticoagulation. A high index of suspicion for DVT is required in cases of neurotrauma, pelvic surgery and fractures.
