Frederick Tolle, BS J Am Coll Cardiol. In a study of 39 patients receiving either an open iliac conduit (23 patients) or an endoconduit (16 patients), those who received an endoconduit had a lower incidence of iliofemoral complications (26.1% vs 12.5%) at a mean follow-up of 10.1 months.4 In this study, the ipsilateral hypogastric artery was covered 37.5% of the time.
The anesthesiologist should be forewarned about these guidewires and watch for any arrhythmias they may cause. in patients with multiple previous abdominal surgeries, Caval-aortic access to allow transcatheter aortic valve replacement in otherwise ineligible patients. If an iliac artery conduit has been performed, there are three different ways to approach the closure, which will be addressed in another section within the Endoluminal Technology Section. A 2010 case series describing the use of the axillary artery in five patients with thoracic aortic disease showed that all patients underwent successful implantation without complications. such as this one who was on warfarin and would not

The currently available devices have an outer diameter (OD) of 24 to 25 F, and some require a sheath, which results in an OD of 26 to 27 F. Currently available low-profile devices include the new Zenith Alpha device (Cook Medical), which has a 16- to 20-F (inner diameter [ID]) delivery system that can be delivered through a 6- to 7.7-mm vessel and treats an aorta with a diameter of 15 to 42 mm. Single-lung ventilation is not required, and once in the chest, the pericardium is identified and opened. In addition, he had normal lower

An angled catheter and guidewire are used to access the abdominal aorta, and then advanced under fluoroscopic guidance into ascending aorta.

Successful use of the transcaval approach has primarily been demonstrated in TAVR.13 In a 2014 series, Greenbaum et al successfully used this technique to access and close the tract in 19 patients undergoing TAVR. The close follow-up (Figure 3) and the chance of postoperative issues requiring re-intervention has to be discussed with the patient as part of the informed consent. 12.

Aortography was performed, Nzara R, Rybin D, Doros G, et al.
In cases with challenging access, the correct site for alternative access will vary based on the anatomy, the device used, as well as the region of the aorta to be treated. Standard access is achieved via the common femoral vein.
The IVUS and guidewire are advanced together, under direct IVUS imaging and fluoroscopy, into the ascending aorta. This technique can be 3.
