Abstract:
Endovascular treatment of abdominal aortic aneurysm (AAA) involves placement of an endoluminal graft inside the aneurysmal sac in order to exclude it from blood circulation and thereby prevent the risk of aneurysmal sac rupture. A possible complication is endoleak, i.e. persistent blood flow outside the lumen of the endograft into the aneurysmal sac. The protocol for treatment monitoring includes abdominal computed tomography (CT) and color Doppler ultrasound (US). The aim of this case report is to present our experience in two cases of endoleak in which diagnosis and treatment were carried out using color Doppler US.

TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
