Branched endoprostheses for endovascular repair of pararenal and thoracoabdominal aortic aneurysms are undergoing evaluation in prospective clinical trials. Duplex ultrasound has been a cornerstone of surveillance for vascular reconstructions. This paper describes the development and deployment of a standardized duplex imaging protocol to evaluate individuals who have undergone endovascular repair of their thoracoabdominal aortic aneurysm. Ultrasound imaging is performed after an 8 to 12 hour fast to minimize the presence of bowel gas and allow for optimal imaging of abdominal vascular structures. Doppler measurements of peak systolic and end diastolic velocity are made at specific arterial segments in the aorta and the celiac, superior mesenteric, and renal arteries. Resistive indices are also recorded in the segmental and arcuate arteries of both kidneys. Pulsed-wave Doppler is used to record spectral Doppler data and color Doppler is used to image all arterial segments and ensure proper placement of the Doppler sample volume and ensure correct angle of interrogation. Implementation of a standardized duplex ultrasound imaging protocol can be used to image and follow individuals who have received the Thoracoabdominal Branch Endoprosthesis (TAMBE) device and branched endovascular aneurysm repair (BEVAR). Ultrasound may provide complementary findings and may add information to the computed tomography angiography imaging for following these individuals.

Abstract OBJECTIVES Our objective was to report the outcomes of fenestrated/branched endovascular aneurysm repair of thoraco-abdominal aortic aneurysms (TAAAs) with endografts. METHODS Between January 2010 and April 2018, patients with TAAAs, considered at high surgical risk for open surgery and treated by Cook-Zenith fenestrated/branched endovascular aneurysm repair, were prospectively enrolled and retrospectively analysed. The early end points were 30-day/hospital mortality rate, spinal cord ischaemia and 30-day cardiopulmonary and nephrological morbidity. Follow-up end points were survival, patency of target visceral vessels and freedom from reinterventions. RESULTS Eighty-eight patients (male: 77%; mean age: 73 ± 7 years; American Society of Anesthesiologists 3/4: 58/42%) were enrolled. Using Crawford’s classification, 43 (49%) were types I–III and 45 (51%) were type IV TAAAs. The mean aneurysm diameter was 65 ± 15 mm. Custom-made and off-the-shelf endografts were used in 60 (68%) and 28 (32%) cases, respectively. Five (6%) patients had a contained ruptured TAAA. The procedure was performed in multiple steps in 42 (48%) cases. There was 1 (1%) intraoperative death. Five (6%) patients suffered spinal cord ischaemia with permanent paraplegia in 3 (3%) cases. Postoperative cardiac and pulmonary complications occurred in 7 (8%) and 12 (14%) patients, respectively. Worsening of renal function (≥30% of baseline level) was detected in 11 (13%) cases, and 2 (2%) patients required haemodialysis. The 30-day and hospital mortality rates were 5% and 8%, respectively. The mean follow-up was 36 ± 22 months. Survival at 12, 24 and 36 months was 89%, 75% and 70%, respectively. The patency of target visceral vessels at 12, 24 and 36 months was 92%, 92% and 92%, respectively. Freedom from reinterventions at 12, 24 and 36 months was 85%, 85% and 83%, respectively. CONCLUSIONS The endovascular repair of TAAAs with fenestrated/branched endovascular aneurysm repair is feasible and effective with acceptable technical/clinical outcomes at early/midterm follow-up.

Purpose: To assess the anatomical suitability of ruptured abdominal aortic aneurysms (AAA) for emergency endovascular repair. Methods: All cases (46 patients [35 men; mean age 74 years, range 54–85]) in which computed tomographic angiography (CTA) confirmed AAA rupture over a 5-year period at our university hospital were reviewed for anatomical suitability for endovascular repair. Measurements were made by a radiologist experienced in anatomical assessment of CT criteria for elective endovascular aneurysm repair (EVAR). Results: The mean aneurysm neck length was 18 mm (range 0–59); 17 were conical, 13 straight, 4 barrel, and 6 reverse conical. Six cases had no proximal neck. Overall, 37 (80%) patients were unsuitable for EVAR according to our criteria. Nearly half the patients (22, 48%) had ≥2 adverse features. Unsuitable neck morphology (35, 76%) was the primary reason for exclusion, but CIA aneurysm (10, 22%) and EIA tortuosity (7, 15%) were secondary adverse features. Conclusions: With current stent-graft design, the majority of ruptured abdominal aortic aneurysms are anatomically unsuitable for endovascular repair.

This chapter provides a summary of the landmark EVAR Trial 1, which compared endovascular repair of abdominal aortic aneurysms (AAA) with open repair in patients judged to be fit for both open and endovascular repair. Although endovascular AAA (EVAR) repair was associated with lower perioperative complications and mortality than open surgical repair, after 4 years of follow-up the outcomes of the two approaches were similar. Follow-up at 15 years found EVAR had inferior late survival, necessitating lifelong surveillance of EVAR and reintervention if necessary. The chapter describes the basics of the study, including funding, year study began, year study was published, study location, who was studied, who was excluded, how many patients, study design, study intervention, follow-up, endpoints, results, and criticism and limitations. The chapter briefly reviews other relevant studies and information, gives a summary and discusses implications, and concludes with a relevant clinical case.

Background: Complex endovascular repair of abdominal aortic aneurysm carries higher perioperative morbidity than standard infrarenal endovascular repair. Objective: This study reviews the incidence and associated factors of acute kidney injury in complex aortic endovascular repair of juxtarenal, pararenal, and thoracoabdominal aortic aneurysms. Methods: A literature review was performed for all studies on the endovascular repair of juxtarenal, pararenal, and thoracoabdominal aneurysms that evaluated rates of acute kidney injury as an outcome. Outcomes were further analyzed by the level of anatomic complexity and method of repair. Results: 52 studies met inclusion criteria, with a total of 5454 individuals undergoing repair from 2004 to 2017. The overall rate of acute kidney injury ranged widely from 0 to 41%, with a rate of hemodialysis from 0 to 19% (temporary) and 0 to 14% (permanent). Increasing anatomic complexity was associated with higher rates of acute kidney injury. Mode of endovascular repair, learning curve effect, and preoperative chronic renal insufficiency did not demonstrate any associations with the outcome. Conclusion: Published rates of acute kidney injury in complex aortic aneurysm repair vary widely with few definitively associated factors other than increasing anatomic complexity and operative time. Further study is needed for the identification of predictors related to postoperative acute kidney injury.

Objectives Stent grafts for endovascular repair of infrarenal aneurysms are commercially available for aortic necks up to 32 mm in diameter. The aim of this study was to evaluate the feasibility of endovascular repair with large thoracic stent grafts in the infrarenal position to obtain adequate proximal seal in wider necks. Methods All patients who underwent endovascular aneurysm repair using thoracic stent grafts with diameters greater than 36 mm between 2012 and 2016 were included. Follow-up consisted of CT angiography after six weeks and annual duplex thereafter. Results Eleven patients with wide infrarenal aortic necks received endovascular repair with thoracic stent grafts. The median diameter of the aneurysms was 60 mm (range 52–78 mm) and the median aortic neck diameter was 37 mm (range 28–43 mm). Thoracic stent grafts were oversized by a median of 14% (range 2–43%). On completion angiography, one type I and two type II endoleaks were observed but did not require reintervention. One patient experienced graft migration with aneurysm sac expansion and needed conversion to open repair. Median follow-up time was 14 months (range 2–53 months), during which three patients died, including one aneurysm-related death. Conclusions Endovascular repair using thoracic stent grafts for patients with wide aortic necks is feasible. In these patients, the technique may be a reasonable alternative to complex endovascular repair with fenestrated, branched, or chimney grafts. However, more experience and longer follow-up are required to determine its position within the endovascular armamentarium.
