CT-Angiographic Aspects of Pulmonary Embolism on SARS COV-2.

Objectives: To study pulmonary embolism during COVID-19 pneumonia. Patients and Methods: This was a one-year retrospective and descriptive study of all patients from three imaging sites with SARS-CoV2 infection. Results: Two hundred and thirty-nine patients were included. The prevalence of pulmonary embolism was 18.4%. The average age was 55 years old. The sex ratio was 1.65. Dyspnea (58.6%), cough (56.1%), and chest pain (40.2%) were the most common reasons for consultation. In 151 patients (63.2%), chest computed tomography (CT) angiography was performed without checking level of D-dimer. The level of D-dimers was elevated in 47.8%. Grade 5 of CO-RADS accounted for 62.3%. In 70.5% of cases, the pulmonary embolism was bilateral with subsegmental involvement in 47.7%.Condensation in 'ground glass' with 'crazy paving' were the predominant typical parenchymal lesions with a frequency of 93.7% and 59.4%. In univariate analysis, D-dimers were significantly associated with the occurrence of pulmonary embolism (p < 0.001). Male sex was associated with a non-significantly higher Risk of having a pulmonary embolism (1.18 95% CI: 0.61-2.31, p = 0.622). The critical level increased the risk of pulmonary embolism in a non-significant way. Only the high level of D-dimers was and this, in a significant way. Conclusion: Pulmonary embolism was increased in the context of SARS-CoV2. The chest CT-angiography associated with the dosage of D-dimers constitutes a good diagnostic arsenal.

Aspects scanographiques de la pneumopathie à COVID-19 à Ouagadougou: Étude multicentrique à propos de 1017 cas.

OBJECTIVE: To study the chest CT profile of SARS-CoV-2 pneumonia in patients in the city of Ouagadougou. PATIENTS AND METHODS: descriptive cross-sectional study with retrospective collection of 1017 patients of both sexes. Included were patients aged 15 and over who had performed a chest CT scan without or with injection of contrast product, suspected or positive for COVID -19. The variables analyzed were: the history, the nature of the examination, the socio-demographic, clinical, CT data including the description of the tomodensitometric lesions and their characteristics, the extent of the parenchymal lesions according to the visual estimate of the French thoracic Imaging Society, complications, other lesions on the chest CT scan and CORADS classification. All parameters (age, sex on the one hand and clinical and CT findings on the other) were subjected to statistical analysis. RESULTS: The mean age of the patients was 56.95 years, predominantly male (1.47). Dyspnea was the most frequent symptomatology, at 46.26% (n = 506). Diabetes was the most common comorbidity with 29.37% (n = 94). Frosted glass opacity accounted for 90.95% of elementary lesions which were predominantly in plaque in 44.35% (n = 451), bilateral in (82.79%) and peripheral subpleural in (81.51%). The lower lobes were the most affected and postero-basal involvement predominant with greater involvement in the right lung. The extent was severe in 28.42% (n = 289). Thirty-nine point twenty-three (39.23)% or 399 of cases presented with complications dominated by pleural effusion at 56.39% (n = 225) and pulmonary embolism at 34.08% (n = 136 ). The lesions were classified as CORADS type in 815 CT reports. CORADS 5 type lesions were found in 47% of patients. Five hundred and ninety-two (592) PCRs of our patients were undetermined, in 58.21%. The PCR was positive in 342 cases or 33.63%. The bi- and multivariate analysis noted: a statistically significant link between the age and the extent of the lesions, between the extent of the lesions and the clinical context, between the extent of the lesions and comorbidities such as diabetes, Hypertension and renal failure. There was also a link between the PCR result and basic lesions such as ground glass and crazy paving and between the occurrence of pulmonary embolism and the presence of hypertension. DISCUSSION: The scanographic profile corresponded to that described in the literature. Frosted glass was the most common elementary lesion. The impairment was severe to critical in patients over 65 with comorbidity. CT angiography was the most requested in front of signs such as dyspnea and desaturation CONCLUSION: A study on CT specificities with precision on the onset of symptoms and the notion of vaccination would complement these results.

Aortic dissection-Pulmonary embolism association: A therapeutic dilemma.

Aortic dissection is a rare but serious condition. Its association with pulmonary embolism is exceptional and produces a real therapeutic dilemma. We are discussing the case of a 67-year-old male patient who presented with paraplegia with infectious syndrome. The chest X-ray performed to screen for an infectious site led to the suspicion of an aortic aneurysm and the CT angiography showed Stanford type B aortic dissection associated with bilateral proximal pulmonary embolism. The treatment was symptomatic and resulted in the patient's death 48 hours after diagnosis. Management of this pathological association is not standardized between establishing anticoagulant therapy and therapeutic abstention. This management depends on the teams and has a very cautious prognosis.

[Myoma, fortuitous discovery or metrorrhagia: Which is more revealing?] / Myome, découverte fortuite ou métrorragie: qui dit mieux?

INTRODUCTION: myoma is commonly diagnosed in our hospital. It can be accidentally discovered or discovered due to metrorrhagia. The purpose of this study is to evaluate the association between the size of myomas and the circumstances under which they are detected and between the location of myomas and the occurrence of bleeding. METHODS: we conducted a cross-sectional study including women aged 18 or older undergoing ultrasound at the University Teaching Hospital Bogodogo and who were diagnosed with at least one uterine myoma over a period of 6 years from January 2012 to December 2018. Binary logistic regression was used to assess metrorrhagia while multinomial logistic regression was used to assess circumstances under which they were detected and size. RESULTS: we assessed 1049 women, among whom 2294 had myomas diagnosed on ultrasound. Each woman had two myomas. The average age of patients was 37 years. Women with myomas larger than 50 mm accounted for 29.7% (n=311). There was a strong association between interstitial, subserosal and submucosal myomas and the occurrence of metrorrhagias (p<0.001). A size less than 50 mm was significantly associated with fortuitous discovery (p=0.016) but not with revealing metrorrhagia (p=0.084). Women who had submucosal myomas (OR=3.13; CI95%= [1.45-6.76]), interstitial and submucosal myomas (OR=2.24; CI95%= [1.05-4.78] as well as interstitial, subserosal and submucosal myomas (OR=3.57; CI95%= [1.88-6.76]) were at higher risk of developing metrorrhagia. Myomas measuring less than 50 mm had twice the odds of revealing fortuitously (RRR=1.80; CI95%= [1.25-2.62]) or by metrorrhagia (RRR=1.75; CI95%= [1.04-2.95]. CONCLUSION: metrorrhagia is more common in women with myomas in specific locations.

[Status of obstetrical echography at the imaging service of the University Hospital Center of Bogodogo from January 1st, 2016 to December 31st, 2018]. / État des lieux des échographies obstétricales au service d'imagerie du Centre Hospitalier Universitaire Bogodogo du 1er janvier 2016 au 31 décembre 2018.

Obstetric ultrasound performed according to standards from its prescription to the report is a guarantee of quality. The aim of our study was to take stock of obstetrical ultrasounds in order to make rational the ultrasound follow-ups of pregnancy. This was a descriptive cross-sectional study with retrospective data collection through the reports of obstetrical ultrasounds performed from the 1st January 2016 to 31st December 2018. Of the 13,487 ultrasounds in the study period, 2,355 were obstetric ultrasounds, constituting 1746% of the ultrasound activity. The mean gestational age was 27.54 years (± 6.19). The CHU Bogodogo was the requesting structure for 86.88%. Paramedics were prescribers in 66.47%. Third trimester ultrasounds made up 57.06%. Gestational age in 12.99% was greater than 37 weeks while in 66.37% gestational age was greater than 24 weeks. Prenatal follow-up was indicated in 54.48%. Pregnancies were progressive in 97.49%. Twin pregnancies represent 2.72% and ultrasound pathological pregnancies 11.80%. Obstetric Doppler was performed in 2.12% with pre-eclampsia as the main indication (52%). There was 1.18% malformation with nervous system involvement in 60.71%. Through this inventory, the training of prescribers of obstetric ultrasound appears essential. The establishment of an observatory of obstetric ultrasound practices would be an asset for the quality of these medical examinations.
