[Traumatic rupture of the aortic isthmus revealed by acute obstruction of the descending thoracic aorta].

A traumatic transection of the upper descending thoracic aorta, undiagnosed, was complicated on the tenth day by an acute obstruction of the descending thoracic aorta. The upper body hypertension resulted in generalised convulsions and cardiac failure with pulmonary oedema. The lower body ischemia resulted in paraplegia, acute ischemia of the lower limbs, liver failure and anuria. An emergency revascularisation of the lower body was achieved by axillary-bifemoral bypass. The improvement of the clinical status allowed complete repair of the aortic transection two days after the extra-anatomic revascularisation. This case emphasizes the severity of the cases with impaired blood flow to the lower body and the benefit of the extra-anatomic bypass in pathology of the upper descending thoracic aorta when complete repair of the aortic transection is associated with an extremely high risk.

[Association of cor triatriatum and obstruction of abnormal left pulmonary venous drainage. Apropos of a case].

A case of subtotal cor triatriatum associated with a partial anomalous pulmonary venous drainage of the left lung, in a 30 months old boy is reported. Diagnosis was suggested by the presence of pulmonary venous obstruction and pulmonary hypertension. Doppler, echocardiogram diagnosed the cor triatriatum and the degree of the pulmonary hypertension. The cine-angiography demonstrated the anomalous, obstructive, left pulmonary venous drainage. The pulmonary hypertension has mandatorised an early surgical cure, the result was satisfactory at 16 months.

[Brucella endocarditis caused by reinfection of an aortic Starr valve. Apropos of a case with a favorable development after valvular replacement].

We report the case of a 36-year old male patient who was admitted for subacute endocarditis on an aortic prosthetic valve implanted 14 years previously for endocarditic valve regurgitation; no pathogen had been isolated at that time. Nine blood cultures were positive for Brucella abortus. The conventional antibiotic therapy did not prevent the formation of an abscess below the aortic annulus. A third antibiotic combination (quinolone and rifampicin) resulted in pyrexia prior to surgery. An atrioventricular block initially noted raised the problem of an associated myocarditis. The risk of Brucella infection existed before the first operation, and five serological tests were positive for that organism between the two episodes, which makes reinfection highly probable. This is the third case of Brucella endocarditis on a prosthetic valve. Its originality lies in its mechanism.
