RESUMO
BACKGROUND: The outcomes of Thoracic Endovascular Aortic Repair (TEVAR) vary depending on thoracic aortic pathologies, comorbidities. This study presents our comprehensive endovascular experience, focusing on exploring the outcome in long term follow-up. METHODS: From 2006 to 2018, we conducted TEVAR on 97 patients presenting with various aortic pathologies. This retrospective cohort study was designed primarily to assess graft durability and secondarily to evaluate mortality causes, complications, reinterventions, and the impact of comorbidities on survival using Kaplan-Meier and Cox regression analyses. RESULTS: The most common indication was thoracic aortic aneurysm (n = 52). Ten patients had aortic arch variations and anomalies, and the bovine arch was observed in eight patients. Endoleaks were the main complications encountered, and 10 of 15 endoleaks were type I endoleaks. There were 18 reinterventions; the most of which was TEVAR (n = 5). The overall mortality was 20 patients, with TEVAR-related causes accounting for 12 of these deaths, including intracranial bleeding in three patients. Multivariant Cox regression revealed chronic renal diseases (OR = 11.73; 95% CI: 2.04-67.2; p = 0.006), previous cardiac operation (OR = 14.26; 95% CI: 1.59-127.36; p = 0.01), and chronic obstructive pulmonary diseases (OR = 7.82; 95% CI: 1.43-42.78; p = 0.001) to be independent risk factors for 10-year survival. There was no significant difference in the survival curves of the various aortic pathologies. In the follow-up period, two non-symptomatic intragraft thromboses and one graft infection were found. CONCLUSION: Comorbidities can increase the risk of TEVAR-related mortality without significantly impacting endoleak rates. TEVAR is effective for severe aortic pathologies, though long-term graft durability may be compromised by its thrombosis and infection.

Background: The funnel technique, the hybrid assembly of a thoracic and abdominal aortic endograft, is advantageous for frail patients where efficient oversizing is not possible for infrarenal wide aortic necks over 34 mm. We sought to determine the advantages and disadvantages of the Funnel-endovascular aneurysm repair (EVAR) technique using 60 mm length thoracic endograft. Methods: This retrospective study included 22 patients, all frail with high comorbidities, who were operated on with the Funnel technique using the 60 mm Lifetech Ankura thoracic endograft, in 7 urgent and 15 elective cases from January 2018. There were no exclusion criteria except having an age < 60 years. Primary endpoints were the technical success and early mortality and morbidity; secondary endpoints were late outcomes such as endoleak, migration, late open surgical conversion, successful sac shrinkage, and enlargement at the infrarenal aortic neck diameter. Results: The patients' mean age was 72.6 ± 7.3 years (62-86 years), with a mean aneurysm diameter of 83.2 ± 16.8 mm and mean infrarenal aortic diameter of 38.7 ± 2.4 mm. There was no early mortality. Technical success was 100%. 21 standard bifurcated and one aorto-uni-iliac abdominal endograft were deployed. The mean fluoroscopy time was 14.3 ± 5.2 minutes. Mean follow-up was 32.8 ± 19.6 months, with no endovascular complications. There was no Type-1a or Type-3 endoleak, migration, infrarenal aortic neck diameter enlargement, or aneurysm sac enlargement. During the follow-up, three patients died, but there was no aneurysm-related mortality. Conclusions: Funnel-EVAR is effective and safe for patients with a wide infrarenal aortic neck diameter when assessing midterm outcomes. Therefore, it should be part of the armamentarium of a vascular surgeon in patients with wide aortic necks > 34 mm.
RESUMO
Background: This study aims to investigate the effect of large proximal aortic neck diameter on post-endovascular aneurysm repair clinical outcomes. Methods: A total of 180 patients (168 males, 12 females; mean age: 69.9±7.4 years; range, 46 to 88 years) who underwent elective endovascular aneurysm repair between June 2016 and September 2021 were retrospectively analyzed. According to the proximal infrarenal aortic neck diameter, the patients were divided into two groups: Group 1 (<25 mm; normal aortic neck) and Group 2 (≥25 mm; pre-aneurysmatic aortic neck). Patient characteristics, proximal infrarenal aortic neck diameter measurements with computed tomography angiography, and clinical outcomes were recorded. The primary endpoint was to assess post-endovascular aneurysm repair aortic neck dilatation, mortality, endoleaks, overall survival, type 1a endoleaks-free survival, and eventfree survival regarding the groups. Results: There was no statistically significant difference in early mortality (p=0.55) and type 1a endoleak incidence between the groups (p=0.55). In Group 1, the mean change in diameter A (proximal infrarenal level) was 2.89±1.74 mm (p=0.01), and it was 2.31±2.1 mm in diameter B (proximal pre-aneurysm-sac level) (p=0.01). The mean change in Group 2 was 2.8±3.4 mm for diameter A (p<0.01) and 2.22±2.3 mm for diameter B (p<0.01). Aortic neck dilatation rates were similar between the groups (p=0.82 for diameter A; p=0.78 for diameter B). The five-year survival, event-free survival, and type 1a endoleak-free survival were also similar (p=0.54, p=0.26, p=0.24, respectively). Conclusion: Our study results showed that patients with <25 mm and ≥25-mm aortic neck diameters had similar mid-term results and aortic neck dilatation ratio. Endovascular aneurysm repair outcomes can be improved with careful patient and graft selection, and early intervention for complications.
RESUMO
OBJECTIVE: All innovations in cardiac surgery provide us with new techniques to perform surgery through smaller incisions with less invasive and best cosmetic results. After promising results in minimally invasive cardiac surgery (MICS), pain and cosmetic appearance became important end points, especially for female patients. In the current study, we intended to evaluate the surgical results and cosmetic satisfaction with the periareolar and submammary incision types in cardiac surgery. METHODS: Ninety-four female patients underwent MICS between July 2013 and March 2018. MICS was performed in 62 patients via periareolar incision and in 32 patients via submammarian incision. We investigated the incision size, wound infection, pain levels by using a postoperative standard pain-level questionnaire, the postoperative scar size, and patient satisfaction using a postoperative patient questionnaire. RESULTS: Periareolar incision size was smaller than the submammary incision (Group A: 5.6±0.6 vs. Group B: 6.7±0.8, p=0.001). Four patients from Group B had superficial wound infection (p=0.01). Patients who underwent MICS via periareolar incision and submammary incision had similar pain level (p=0.2). The scar tissue was smaller in size and postoperatively healed better in the following days for the patients with periareolar incision due to the elastic structure of breast tissue. (Group A: 4.3±0.4 vs. Group B: 5.3±0.2, p=0.001). CONCLUSION: Our study suggests that the periareolar approach would be more aesthetic, show better healing, and have a smaller scar size in female patients.
