Surgeon-Modified Fenestrated Stent-grafts for Zone 2 Endovascular Repair of Blunt Traumatic Thoracic Aortic Injury: Early and Midterm Results.

Aim: Blunt traumatic thoracic aortic injury (BTAI) is a highly fatal surgical emergency and is treated with endovascular procedures. We aimed to analyze and report the early and midterm outcomes of surgeon-modified fenestrated stent-grafts (SMFSG) compared with other conventional endovascular methods in patients with BTAI repaired with zone 2 endovascular surgery.

Materials And Methods: Before and after the study was performed, from January 2015 to January 2020 for a period in which conventional endovascular treatments were used and from January 2020 to January 2023 for the second period in which the SMFSG technique was used.

Combined Endovascular Treatment of Complex Aortic Pathologies.

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.

Funnel technique for wide infrarenal aneurysm neck with Lifetech Ankura™ Stent Graft System.

Background: In this study, we present our mid-term results in patients undergoing treatment with the funnel technique and describe technical issues for this bailout technique in extra-wide infrarenal necks.

Methods: Between January 2018 and June 2020, a total of seven male, symptomatic patients (median: 74.5 years; range, 64 to 84 years) who had comorbidities and were in the American Society for Anesthesiologists Class IV and treated by the funnel technique in an endovascular fashion were included.

What factors counteract mid-term survival following endovascular repair of abdominal aortic aneurysms?

Introduction: Endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA) is increasingly used, and has become the standard treatment option for AAA.

Aim: To evaluate the outcomes and predictors of survival of endovascular treatment of AAA in the short- and medium-term.

Material And Methods: A total of 222 patients having endovascular AAA repair between January 2013 and December 2019 by the same surgical team were included in the study.

Long-term results of endovascular intervention with unibody bifurcation endograft for elective abdominal aortic aneurysm management.

Unibody bifurcated endografts have the advantage of reducing the operative time, avoiding migration and iliac limb dislocation in patient with abdominal aortic aneurysm (AAA). We report our long-term experience in patients who underwent endovascular aortic repair (EVAR) due to infrarenal AAA with Endologix AFX® endograft system. Between January 2013-December 2018, 68 patients with infrarenal AAA had EVAR procedure with Endologix AFX® endograft system.

Elective Endovascular Repair of Abdominal Aortic Aneurysms with Modular and Unibody Type Endografts.

Background: In this study, we aimed to evaluate the performance of modular and unibody endografts for the endovascular repair of abdominal aortic aneurysm (AAA).

Methods: Between January 2012 and December 2017, 130 elective infrarenal abdominal aortic aneurysms treated in an endovascular manner were retrospectively evaluated. Sixty-six patients with the modular type (Medtronic Endurant II and Lifetech Ankura AAA) and 64 patients with the unibody type (Endologix AFX®) were compared with regards to early and postoperative one-year results.

Outcomes after EVAR in females are similar to males.

Introduction: Women are less likely to develop infrarenal abdominal aortic aneurysm; however, when they do, it is almost always associated with challenging anatomy, more rapid aneurysmal growth rate and earlier rupture. Women generally have poorer outcomes following open aneurysm repair; and in this respect, the present study aims to evaluate if it is so after endovascular repair.

Methods: A retrospective analysis of our database was performed for patients underwent endovascular aneurysm repair (EVAR) between January 2013-March 2020.

Building a patient blood management program in a large-volume tertiary hospital setting: Problems and solutions.

Successful implementation of a patient blood management program necessitates the collaboration of a strong organization and a multidisciplinary approach. We organized a meeting with broad participation in our center to establish a consensus for implementation of a specific patient blood management program. International and domestic experiences were shared, the importance of coordination and execution of different pillars in patient blood management were discussed, and the problems about the blood transfusion system were also investigated with the proposal for solutions.

Perioperative planning for cardiovascular operations in the COVID-19 pandemic.

Coronavirus disease-2019 (COVID-19) is a serious health concern which alert all healthcare professionals worldwide. There are two main issues caused by this pandemic regarding for the healthcare system. First, it is a necessity to postpone many elective procedures/surgeries to reduce the burden of the healthcare system which may be confronted with strain by the increased speed of transmission.

The comparison of the effects of Bretschneider's histidine-tryptophan-ketoglutarate and conventional crystalloid cardioplegia on pediatric myocardium at tissue level.

Cardioplegic arrest is one of the most common myocardial protection strategies. A wide variety of cardioplegic solutions are routinely being used. There is an ongoing discussion about the relative effectiveness of these solutions considering myocardial protection.

Pulsatile flow improves renal function in high-risk cardiac operations.

The effects of pulsatile perfusion on microcirculation and renal function in high-risk patients were evaluated in this study. Pulsatile roller pumps with a pulsatile control module and membrane oxygenator were used in a clinical setting. 40 patients undergoing elective cardiac surgery with a high risk of either having chronically obstructive pulmonary disease or chronic renal failure were randomly included in the study to be perfused using pulsatile or continuous flows.

Do S100beta protein level increases due to inflammation during cardiopulmonary bypass occur without any neurological deficit?

Purpose: S100beta protein level correlates with the duration of cardiopulmonary bypass (CPB) and aortic crossclamp times, but is different during pulsatile and nonpulsatile CPB. In this study, we investigated the time course of the release of S100beta protein during and after pulsatile and nonpulsatile CPB.

Patients And Methods: This is a prospective study.
