Value of Intravascular Phased-Array Probe in Diagnostics and Treatment of Aortic Dissection

Abstract

Two clinical cases of the aortic dissection (DeBakey III) endovascular treatment with intravascular phased-array probe use are presented. Literature review is given as well. The disease was diagnosed by the aorta, iliac arteries, and lower extremities arteries ultrasound examination, computed tomography, and aortography. Aortic endovascular fenestration under intravascular ultrasound control was performed. Ultrasound investigation was performed using Acuson Sequoia 512 scanner (Siemens, Germany) equipped with the intravascular phased-array probe AcuNav applying B-mode, colour Doppler, and pulsed Doppler. Intravascular ultrasound allowed assessing hemodynamics in the true and false lumen of aorta and its branches during the aortic endovascular fenestration. Intravascular ultrasound allowed showing that endovascular fenestration makes the blood flow speed in the true aortic lumen equal to the false one. In conclusion, intravascular ultrasound allowed assessing hemodynamics before, during, and after the aortic fenestration and estimate fenestration efficacy.
