[Pulmonary embolism at the University Hospital Campus of Lome (Togo): a retrospective study about 51 cases].

INTRODUCTION

This study provides an analysis of the evolutionary, clinical and epidemiological aspects of pulmonary embolism at the University Hospital Campus of Lome.

METHODS

We conducted a retrospective, analytic and descriptive study over a period of 39 months (November 1 , 2011- January 31, 2015). All the medical records of patients hospitalized for PE in the Department of Cardiology at the University Hospital Campus were analyzed.

RESULTS

The prevalence of PE was 3.1%. Female/male sex ratio was 2.2. The average age was 52.7 ± 14.4 years. Risk factors for venous thromboembolic disease VTD were dominated by: obesity (54.9%), bedrest (25.5%) and long journey (17.6%). The main symptoms were: dyspnoea (98.0%), chest pain (78.4%) and cough (60.8%). Wells' score was high in 29.4% of cases. ECG showed: tachycardia (78.4%), right ventricular hypertrophy (RVH)(49.0%), S1Q3T3 aspect (47.1%) and right block (39.2%). Transthoracic Doppler echocardiogram showed right cavitary dilation and right intraventricular thrombus in 5.6% of cases. Thoracic angioscanner was normal in 9.8% of cases and showed embolus in 82.4% of cases. Treatment was based on Low Molecular Weight Heparin (LMWH) at therapeutic doses with antivitamin K (AVK) relay. Thrombolysis was performed in 8 patients. Evolution was favorable in 86.3% of cases. Case-fatality rate was 13.7%.

CONCLUSION

The prevalence of PE is relatively low in our area but it is probably underestimated. PE is a therapeutic problem in Togo because of the high cost of complementary examinations and thrombolysis. Prevention is therefore the only effective weapon.
