The Mean

In recent years, endovascular treatment of aortic aneurysms has attracted considerable attention as a promising alternative to traditional surgery. Hybrid operating room systems (HORSs) are increasingly being used to perform endovascular procedures. The clinical benefits of endovascular treatments using HORSs are very clear, and these procedures are increasing in number. In procedures such as thoracic endovascular aortic repair (TEVAR) and endovascular aortic repair (EVAR), wires and catheters are used to deliver and deploy the stent graft in the thoracic/abdominal aorta under fluoroscopic control, including DSA. Thus, the radiation dose to the patient is an important issue. We determined radiation dose indicators (the dose–area product (DAP) and air karma (AK) parameters) associated with endovascular treatments (EVAR and TEVAR) using a HORS. As a result, the mean ± standard deviation (SD) DAPs of TEVAR and EVAR were 323.7 ± 161.0 and 371.3 ± 186.0 Gy × cm2, respectively. The mean ± SD AKs of TEVAR and EVAR were 0.92 ± 0.44 and 1.11 ± 0.54 Gy, respectively. The mean ± SD fluoroscopy times of TEVAR and EVAR were 13.4 ± 7.1 and 23.2 ± 11.7 min, respectively. Patient radiation dose results in this study of endovascular treatments using HORSs showed no deterministic radiation effects, such as skin injuries. However, radiation exposure during TEVAR and EVAR cannot be ignored. The radiation dose should be evaluated in HORSs during endovascular treatments. Reducing/optimizing the radiation dose to the patient in HORSs is important.

Objective Endoluminal aortic aneurysm repair is suitable within certain anatomic specifications. This study aims to compare 30-day outcomes of endovascular versus open repairs for juxtarenal and pararenal aortic aneurysms (JAA/PAAs). Methods The ACS-NSQIP database was queried from 2012 to 2015 for JAA/PAA repairs. Procedures characterized as emergent were included in the study; however, failed prior repairs and ruptured aneurysms were excluded. The preoperative and perioperative patient characteristics, operative techniques, and outcome variables were compared between the open aortic repair and the endovascular aortic repair groups. Propensity scoring was performed to clinically match open aortic repair and endovascular aortic repair groups on preoperative risk and select perioperative factors that differed significantly in the unmatched groups. Outcome comparisons were then performed between matched groups. Results A total of 1005 (789 JAAs and 216 PAAs) aneurysm repairs were included in the study. Of these, there were 395 endovascular aortic repairs and 610 open aortic repairs. Propensity scoring created a matched group of 263 endovascular aortic repair and 263 open aortic repair patients. There was no statistically significant difference in 30-day mortality rates between matched endovascular aortic repair and open aortic repair patients (2.7% vs. 5.7%). The endovascular aortic repair group had a shorter ICU length of stay and overall hospital stay. The 30-day morbidity significantly favored endovascular aortic repair over open aortic repair (16% vs. 35%, p < 0.001). The main drivers of morbidity for endovascular aortic repair versus open aortic repair included return to the OR (6.8% vs. 15%, p < 0.001), rate of cardiac or respiratory failure (7.6% vs. 21%, p = 0.001), rate of renal insufficiency or failure (3.8% vs. 9.9%, p = 0.009), and rate of pneumonia (1.5% vs. 6.8%, p = 0.004). Conclusions There is no difference in mortality rates between endovascular aortic repair versus open aortic repair when repairing JAAs/PAAs. There is a significant difference in overall morbidity, and ICU and hospital length of stay favoring endovascular aortic repair over open aortic repair. This supports the expanded applicability and efficacy of endovascular repair for complex aneurysms.

Objective: Our study aimed to examine retrospectively the anesthesia techniques and their results applied to patients who underwent endovascular aortic repair due to aortic pathology. Methods: This retrospective and observational study included patients who underwent EVAR or TEVAR for abdominal and/or thoracic aortic aneurysm between 2015-2021. Patients’ demographic data, type of surgery and anesthesia, duration of surgery and anesthesia, amount of blood transfusion, lengths of stay in ICU and of hospital were recorded. Results: The data of 206 patients who underwent EVAR and TEVAR for abdominal and/or thoracic aortic aneurysm were obtained. TEVAR was applied to 63 patients and EVAR was applied to 143 patients. The procedure was performed under general anesthesia (GA) in all 63 patients who underwent TEVAR, while 15 patients who underwent EVAR were operated under GA and 128 patients under regional anesthesia (RA). The mean anesthesia and surgery times were found 136.1±72.0 min. and 112.2±71.3 min. in GA patients and it was 112.2±71.3 min. and 96.5±32.1 min. in RA patients. The mean length of ICU and hospital stays were determined as 1.6±2.1 days and 3.1±2.7 days in GA patients, and 1.2±0.6 days and 3.1±2.5 days in RA patients. Conclusion: GA or RA methods are preferred as anesthesia techniques in patients undergoing EVAR due to aortic aneurysm. Although RA has advantages compared to GA, such as shorting the lenght of hospital and ICU stays, reducing the blood product requirements, shorting both anesthesia and surgery times, patient characteristics should also be considered in the selection of anesthesia techniques.

Objective Reports on inflammatory aortic abdominal aneurysm treatment are scarce. Traditionally, open surgery has been validated as the gold standard of treatment; however, high technical skills are required. Endovascular aortic repair has been suggested as a less invasive treatment by some authors offering good results. The purpose of our study was to report our experience and outcomes in the treatment of inflammatory aortic abdominal aneurysm using both approaches. Material and methods A retrospective review and data collection of all patients treated for inflammatory aortic abdominal aneurysm between 2000 and 2015 was done in one academic center. Diagnosis of inflammatory aortic abdominal aneurysm was based on preoperative CT-scan imaging. Type of treatment, postoperative and long-term morbidity and mortality are described. Abdominal compressive symptoms (hydronephrosis) severity and relief after treatment are described. Results Thirty-four patients with intact inflammatory aortic abdominal aneurysm were included. Twenty-nine (85.3%) patients were treated by open means and the remaining five (14.7%) with endovascular aortic repair. Nearly 90% were considered high-risk patients. Median follow-up was 46 months (range 24–112). The two groups were comparable, except for the age and preoperative hydronephrosis. There was no statistical significance in blood transfusion requirements, intensive care hospitalization, 30-day and long-term mortality between the two groups. Preoperative hydronephrosis was diagnosed in four (13.8%) patients in the open surgery group and three (60%) patients in the endovascular aortic repair group. Improvement of hydronephrosis was recognized in three out of the four patients in the open repair group and two out of the three in the endovascular aortic repair group. Renal function remained stable in both groups during follow-up. Conclusions Open surgery remains a safe and valid option for the treatment of inflammatory aortic abdominal aneurysm. Although our study included a small number of patients with endovascular aortic repair treatment, results are promising. Further randomized controlled studies may be necessary to assess long-term effectiveness of endovascular aortic repair treatment in this disease.
