Key result
Aortic dissection in Benin carries a ~47% lethality rate linked to widespread uncontrolled hypertension.
Why the study?
The authors aimed to describe the epidemiological, diagnostic, and therapeutic aspects of aortic dissection managed at the CNHU-HKM of Cotonou in Benin.

Aortic dissection in Benin is associated with high mortality (47%) and low rates of surgical or endovascular intervention (35%), highlighting the need for improved hypertension management and access to care.

High lethality with low intervention rates signals care gaps in Benin; hypothesis-generating for targeted hypertension and access strategies in similar settings.
Introduction: We aimed to describe epidemiological, diagnostic, therapeutic aspects of aortic dissection (AD) managed at the CNHU-HKM of Cotonou (Benin). Methods: It was a retrospective study from january 2018 to july 2023. All patients admitted for AD were enrolled. AD was classified as type A and type B according to Stanford. DA risk factors, socio-demographic characteristics and DA characteristics were studied. Results: Of the 2883 patients admitted during the study period, there were 17 cases of AD, representing a frequency of 0.6%. The mean age was 52 ± 9 years, and the sex ratio was 3.25. Uncontrolled hypertension was the predominant risk factor (88.3%). The main manifestations of AD were chest pain (100%) and aortic insufficiency (52.94%). Chest X-rays showed enlargement of the mediastinum in all patients. Echocardiography showed intimal flap in 62.5%. The aortic angiotomodensitometry, identified 12 type A (70.59%) and 5 type B (29.41%) of AD. Surgical or endovascular treatment was performed in 6 (35.29%) patients. Lethality rate was 47.06%. Conclusion: Aortic dissection was frequent at the teaching clinic of cardiology of CNHU-HKM of Cotonou. Surgical or endovascular treatment wasn't often available, and mortality was high. Prevention of this condition must be the rule, and it requires adequate management of hypertension, which is the most common risk factor.

Bata et al. (2023) conducted an observational in Aortic Dissection (n=17). Aortic Dissection was evaluated on Lethality rate. Among 17 patients managed for aortic dissection at a cardiology clinic in Benin, the lethality rate was 47.06%, with uncontrolled hypertension present in 88.3% of cases.
