Abstract

Introduction: Venous thromboembolic diseases (VTED) include deep vein thrombosis of the lower limbs and pulmonary embolism (PE), which is its severe form due to its high mortality. The objective of our study was to determine the epidemio-clinical and paraclinical aspects of patients hospitalized for venous thromboembolic diseases. Patients and method: Cross-sectional study with prospective recruitment from patient records hospitalized for (VTED) from January to December 2023 in the cardiology department of the Mother-Child University Hospital in Bamako, Luxembourg. Results: We collected 55 out of 580 patient records hospitalized for (VTED), a hospital frequency of 9.48%. PE accounted for 58.20% of cases, 10.90% for deep vein thrombosis (DVT), and 30.90% for their association. The mean age of patients was 55.56 years ± 15.52 years. The majority of patients, 90%, were under 66 years of age. The predominance was female, 56%. In lower extremity DVT, calf pain and Homans' sign were present in 56% and 24% of patients. In pulmonary embolism, dyspnea and chest pain were present in 85.50% and 65.50% of patients. Etiological factors were dominated by neoplasia in 10.90%, contraception 5.45% and orthopedic surgery in 5.45% of cases. Cardiovascular risk factors were a sedentary lifestyle (50.90%), obesity (34.45%), high blood pressure (36.36%) and diabetes (21.81%). Laboratory abnormalities were elevation of troponin (46.87%), BNP (40.62%), D-Dimer (62.50%) and anemia (9.09%). Electrocardiographic abnormalities were tachycardia in 65.4% and S1Q3 in 21.81% of patients. Echocardiography showed dilation of the right cavities (47.27%), systolic pulmonary arterial hypertension (38.18%) and thrombus in the right cavitary (5.45%). On thoracic CT angiography, PE was proximal (36.40%), bilateral (61.80%) and massive (29.10%). On venous Doppler ultrasound, TVP was proximal in 65.21%. Conclusion: VETD was more common in women and younger subjects.

1. Introduction
Venous thromboembolic disease (VTED) includes deep vein thrombosis of the lower extremity and pulmonary embolism . Venous thromboembolic disease is a serious disease with significant morbidity and mortality. In 2004, 370,000 deaths were attributed to VTE in 6 European countries . In sub-Saharan Africa, they are underdiagnosed because of clinical polymorphism, hence the initiative of this work, which is set as an objective.
2. Patients and Method
This is a cross-sectional study with prospective recruitment over a period of one year, from January to December 2023, carried out in the cardiology department of the Mother-Child University Hospital in Bamako, Luxembourg. All patients of both sexes and of all ages hospitalized in the VTE department confirmed by CT angiography of the pulmonary arteries and/or venous Doppler ultrasound of the lower extremities were included. Information was collected for each patient on a card. The diagnosis of VTE was based on clinical evidence, Wells Clinical Probability (DVT) and Revised Geneva (EP) Clinical Probability Scores, and data from venous lower extremity Doppler ultrasound and CT angiography of the pulmonary arteries. Sociodemographic characteristics of patients, etiological factors of VTE (cancer, recent surgery, especially orthopedic surgery, contraception, prolonged bed rest, postpartum), cardiovascular risk factors (hypertension, diabetes, smoking, dyslipidemia, obesity, sedentary lifestyle, heredity) were sought. Data were entered on Word 2016 and Excel 2007 and analyzed on SPSS version 22. Confidentiality was respected and data processing was anonymous.
3. Results
We collected 55 out of 580 patient records hospitalized for VTE, i.e. a hospital frequency of 9.48%. PE accounted for 58.20% of cases, 10.90% for DVT, and 30.90% for their association (Figure 1). The mean age of patients was 55.56 years ± 15.52 years. The majority of patients, 90%, were under 66 years of age. The predominance was female, 56%. In lower extremity DVT, calf pain and Homans' sign were present in 56% and 24% of patients. In pulmonary embolism, dyspnea and chest pain were present in 85.50% and 65.50% of patients. Etiological factors were dominated by neoplasia in 10.90%, contraception 5.45% and orthopedic surgery in 5.45% of cases. Cardiovascular risk factors were physical inactivity (50.90%), obesity (34.45%), hypertension (36.36%) and diabetes (21.81%) (Table 1). Laboratory abnormalities were elevation of troponin (46.87%), BNP (40.62%), D-Dimer (62.50%) and anemia (9.09%). Electrocardiographic abnormalities were tachycardia in 65.4% and S1Q3 in 21.81% of patients. Echocardiography showed dilation of the right cavities (47.27%), systolic pulmonary arterial hypertension (38.18%) and thrombus in the right Right cavitary (5.45%). On thoracic CT angiography, PE was proximal (36.40%), bilateral (61.80%) and massive (29.10%). On venous Doppler ultrasound, DVT was proximal in 65.21% (Table 2).

4. Discussion
The hospital frequency of VTED in the study was 9.48%, close to Damorou's 9.1% , higher than Owono's 1.6% , Igun's 3.80% , and Coulibaly's 4.95% , but lower than Thiam's 26% . The distribution of VTED was 58.20% isolated pulmonary embolism, 10.90% isolated deep vein thrombosis and their association of 30.90%, the same observation made by Coulibaly and Thiam in disagreement with Mbaye , Nourelhouda and Simeni who found the predominance of DVT with 66.7% and 49.5% respectively. The mean age of our patients was 52.9 ± 16.4 years with extremes of 29 and 80 years in agreement with the literature .
The predominance was female, superimposed on the rest of the literature . The cardiovascular risk factors found were a sedentary lifestyle (50.90%), obesity (50.90%), high blood pressure (36.36%) and diabetes (21.81%) in agreement with Owono and Ondze-Kafata , while Diall found in his series arterial hypertension and heart disease . For Diedhiou , it was mainly heart failure. The classic etiological factors of VTED were cancer (10.90%), orthopedic surgery (5.45%) and contraception (5,45%). In his series Camara , found 5.6% cancer and 24.1% recent surgery. For Coulibaly , cancer was 16.10% and recent surgery 11.50%. Functional signs in pulmonary embolism were dominated by dyspnea (85.50%) and chest pain (65.50%) in agreement with Damorou . which found 98% and 78.4% respectively. For lower extremity DVT, the clinic was dominated by calf pain (56%) and a positive Homans sign (24%), in agreement with Diedhiou . In our study, the biological abnormalities were elevation of troponin (46.87%), BNP (40.62%), D-Dimer (62.50%) and anemia (9.09%). Coulibaly in his series found an elevation of D-Dimer (100%) of patients and anemia (34.34%). This difference can be explained by the non-systematization of the determination of D-Dimer in our study. Tachycardia (65.45%) and an S1Q3 appearance (21.81%) were the most common electrocardiographic abnormalities in agreement with Camara . On transthoracic echocardiogram and in agreement with Damorou , Coulibaly , right cavitary dilation (47.27%) and PAH (38.18%) were the frequent abnormalities. Venous Doppler ultrasound of the lower limbs found DVT of the lower limbs in 41.81% of cases and it was proximal in the majority of cases (65.21%). In the Camara series of lower extremity DVT was proximal in 56.50% of cases. On CT angiography of the pulmonary arteries, PE was bilateral in 63.33% of cases and proximal in 56.66%s close to MBaye data which found bilateral PE in 74% and proximal in 50% of cases. On the other hand, for Camara , the PE was proximal and distal with 50% each. The embolism was massive in 26.66% of our patients lower than the 33.3% of Camara .
5. Conclusion
Venous thromboembolic diseases are relatively common but underdiagnosed. The predominance was female and affected more subjects under 65 years of age. The classic functional signs were found, namely dyspnea, chest pain and calf pain. The contributing factors were a sedentary lifestyle, obesity and a history of cancer. Proximal and bilateral pulmonary embolism were the most common CT abnormalities and deep vein thrombosis of the lower limbs was proximal in more than half of the cases to venous Doppler of the lower limbs.
6. Limitations of the Study
