    Abstract The treatment of aortic dissections and aneurysms may be challenging for vascular surgeons. Currently, thoracic endovascular aortic repair is usually the first treatment option for descending aortic pathologies. Left subclavian artery coverage during this procedure is often required to achieve a sufficient proximal landing zone. Most surgeons agree that the left subclavian artery can be selectively covered, but revascularization is preferred to reduce the risk of neurological or ischemic complications. The chimney method, hybrid operations with extra-anatomic bypass, back table or in situ fenestrations are assistive techniques in this procedure. Herein, we present a surgeon-modified fenestrated stent graft for a type B aortic dissection patient.

    Abstract Background: One of the most important factors that affects the success of Endovascular Aortic Repair (EVAR) treatment is the morphology of the neck of the aneurysm. Today, EVAR can be performed even in patients who do not meet the Instruction For Use criteria with hostile neck risk factors; thanks to the developing experience and technology. Our aim in this study was to determine risk factors for Type 1a endoleaks in patients who underwent EVAR and predictive factors for Type 1a endoleaks in patients with combinations of these risk factors.
    Methods: Patients who underwent elective EVAR for infrarenal abdominal aortic aneurysm in our medical center between July 2016 and January 2021 were enrolled. Of these 244 patients, 180 patients with documented preoperative and postoperative computed tomographic angiography results and a follow-up of at least 1 year were included in the study. The Mann-Whitney U test and Student's t-test were used to assess the relationship between nominal data and numerical values, and the t-test and Wilcoxon test were used to compare dependent groups. Logistic regression analysis was performed to model risk factors associated with endoleaks.
    Results: The results showed that a neck length less than 15 mm increased the development of type 1a endoleak by 10.4 times (P < 0.001). Furthermore, a neck diameter more than 28 mm increased the development of type 1a endoleak by 21.9 times (P = 0.04). A conical neck structure (gradual neck dilation > 2 mm) increased the development of type 1a endoleaks 4.8 times (P = 0.04). The presence of calcification (> 150 Hounsfield Unit and > 2 mm) in the neck increased the risk of type 1a endoleaks fourfold (P = 0.04). Hostile neck parameters were analyzed and patients with only 1 parameter (n = 69) had a 7.2% type 1a endoleak rate, while patients with 2 parameters (n = 15) had 26.6% and patients with more than 2 parameters (n = 11) had 45.5% type 1a endoleak rate.
    Conclusions: Morphologic features of the neck structure of the aneurysm are among the most important parameters that affect the success of EVAR treatment. Alternative treatments should be considered in patients with more than 1 unfavorable neck parameter.

    Abstract Aim:  Multisegmented aortic pathologies present challenging issues independent of the treatment chosen. Whether open or endovascular, staged, or simultaneous, every treatment modality has its own pros and cons. We revealed our patients retrospectively with early and midterm results who had simultaneous endovascular thoracic and abdominal aortic repair for thoracic aortic pathologies and infrarenal abdominal aortic aneurysm (iAAA) as a single-center experience.
    Materials and methods:  Between January 2016 and January 2021, 16 patients were diagnosed with thoracic aortic pathology and iAAA was simultaneously repaired in an endovascular manner. All patients were operated on with the same cardiovascular surgeon team.
    Results:  The average age of the patients were 76.9 ± 6.2 (64-86) years. There was no early mortality. The technical success was 100%. In total, 18 thoracic endografts were deployed in 16 patients for thoracic aortic pathologies. Follow-up period was 21.85 ± 8.96 months, and in the follow-up period, two patients had a secondary intervention. One cardiac and one coronavirus disease 2019 mortality was detected in the follow-up period. There was no aneurysm-related mortality. The postoperative first-year survival was 84.6 ± 10.0.
    Conclusion:  Simultaneous endovascular solution for complex multisegmented aortic pathologies provides a rapid, less-invasive approach with successful early and midterm morbidity, mortality with short intensive care unit period, and length of hospital stay. A combination of endovascular aortic aneurysm repair and thoracic endovascular aortic repair where anatomic suitability exists is a strong alternative over staged and hybrid therapies. Contrast-induced nephropathy, postimplantation syndrome, and spinal cord ischemia should be carefully monitored with this strategy.
