Endovascular prosthetic replacement of thoracic and abdominal parts of the aorta

The minimally invasive endovascular surgical intervention is performed in an operating room under local anesthesia and intravenous anesthesia. By a surgical team (surgeon, assistant, surgical nurse), for the treatment of an aneurysmal lesion of descending thoracic aorta or infrarenal abdominal aorta that requires surgical correction.

A surgeon performs the puncture of the radial artery or the common femoral artery and vein transcutaneously and injects a contrast agent selectively for the angiography of an aortic pathology and anatomical contours with a PigTail catheter. A lead for the temporary cardiac stimulation (for the prosthesis replacement of thoracic aorta, if needed) is implanted into the right ventricle cavity. The surgery is performed under the constant invasive blood pressure control only. A surgeon introduces an intravascular hydrophilic conductor with the diameter of 0.035’’ into the aortic ampoule using a diagnostic catheter and performs the replacement of the conductor using a diagnostic catheter on the stiff guide wire to deliver the aortic endoprosthesis according to the “monorail” system. The aortic endoprosthesis is implanted with cardiac stimulation if needed (heart rate is 120 to 180 beats per minute). Aortic angiography is performed to determine the correct aortic prosthesis replacement (of the aortic branches), the presence of the endolic an the necessity of further manipulations, balloon post-dilatation of the endoprosthesis is performed if indicated. A surgeon records the end result on the angiograph in various projections. After the examination the surgical instruments are removed, and the hemostasis of the vascular accesses is performed.

Service duration: 40 to 60 minutes.
