The combination of iliac branch device with parallel stent graft to preserve bilateral internal iliac arteries in a patient with infrarenal abdominal aortic and bilateral common iliac artery aneurysm with short common iliac lengths: A case report.

Coexistent aneurysmal involvement of common iliac artery is frequently seen in patients with infrarenal abdominal aortic aneurysm. Bilateral iliac branch devices are an option to preserve bilateral internal iliac arteries in order to decrease the risk of buttock claudication. In Asian population, however, the aortoiliac lengths are commonly not adequate for bilateral iliac branch endoprosthesis.

Effects and trend of steroid dosage reduction during cardiac surgery: A three-year retrospective analysis at a tertiary medical center.

Background: Current adult cardiac surgery guidelines recommend against the routine use of prophylactic intravenous corticosteroids during cardiopulmonary bypass (CPB) due to concerns about myocardial injury, despite their potential to reduce postoperative atrial fibrillation. Traditionally, a high dose of 1,000 mg of methylprednisolone was used to attenuate the inflammatory response associated with CPB. Our institution aligned with guideline recommendations and gradually reduced methylprednisolone dosages; thus, we reevaluated the impact on postoperative clinical outcomes.

Case report: Total arch replacement with a frozen elephant trunk utilizing open hybrid in-situ fenestration technique for thoracic aortic arch aneurysm.

Introduction: The frozen elephant trunk technique is a surgical procedure developed for concomitant repair of downstream descending thoracic aorta as a first stage operation for arch resections. Proximalization of the sutured anastomosis reduces technical difficulty of total arch replacement. In this procedure, an anastomosis is performed more proximally using a stent graft.

Long-term outcomes of aortic valve replacement in dialysis patients - a nationwide retrospective cohort study.

Background: Improved durability of modern biologic prostheses and growing experience with the transcatheter valve-in-valve technique have contributed to a substantial increase in the use of bioprostheses in younger patients. However, discussion of prosthetic valve selection in dialysis patients remains scarce as the guidelines are updated. This study aims to compare long-term outcomes between propensity score-matched cohorts of dialysis patients who underwent primary aortic valve replacement with a mechanical prosthesis or a bioprosthesis.

Validation of the European system for cardiac operative risk evaluation II in a large Taiwan cardiac surgical centre.

Background: The European System for Cardiac Operative Risk Evaluation (EuroSCORE II) is a well-established scoring system for predicting mortality in cardiac surgery. This system was derived predominantly from a European patient cohort; however, no validation of this system has been conducted in Taiwan. We sought to assess the performance of EuroSCORE II at a tertiary centre.

A Randomized Trial of Postoperative Handgrip Exercises for Fistula Maturation in Patients With Newly Created Wrist Radiocephalic Arteriovenous Fistulas.

Introduction: We aimed to substantiate the benefit of postoperative handgrip exercises (HGEs) in enhancing the maturation of an arteriovenous wrist fistula.

Methods: We randomly assigned 119 patients aged 20 to 80 years who had wrist arteriovenous fistulas (AVFs) to undergo either a basic HGE program (group A), an advanced program (group B), or an advanced-plus upper arm banding program (group C). Outcomes were assessed by ultrasonographic evaluation of the diameter and flow at each follow-up.

Aortic remodeling after endovascular aortic repair and tailored distal entry tears exclusion in Crawford type III or IV dissection aneurysm.

Background: Thoracic endovascular aortic repair (TEVAR) can only promote 55-80% false lumen (FL) thrombosis when only the proximal primary tear is covered during the repair of type B aortic dissection (TBAD). This study evaluated the effectiveness and clinical outcome of tailored exclusion of the primary entry tear with TEVAR and distal fenestrations with ancillary devices in patients with subacute or chronic Crawford type III and IV aortic dissection aneurysm.

Methods: All patients underwent either TEVAR for primary entry tear; subsequently, various ancillary devices were applied on each distal fenestration.

Comparison of Superior Mesenteric Artery Remodeling and Clinical Outcomes between Conservative or Endovascular Treatment in Spontaneous Isolated Superior Mesenteric Artery Dissection.

Outcome Comparison Between Open and Endovascular Aortic Repair for Retrograde Type A Intramural Hematoma With Intimal Tear in the Descending Thoracic Aorta: A Retrospective Observational Study.

The optimal treatment modality for retrograde type A intramural hematoma (IMH) remains debatable. This study evaluated and compared surgical outcomes and aortic remodeling after open aortic repair and thoracic endovascular aortic repair (TEVAR) in patients with retrograde type A IMH with a primary intimal tear or ulcer like projection in the descending aorta. A single center, retrospective observational study was performed on patients with retrograde type A IMH undergoing either open aortic repair and TEVAR.

Comparison of robotic and conventional sternotomy in redo mitral valve surgery.

Background/purpose: Redo operation for mitral valve surgery carries higher risks than first time cardiac surgery. The adhesion between sternum and heart, and also the complexity of second time operation make the redo operation more difficult. The robotic surgery carries some benefit in terms of magnification, assisted by the scope view and precise movement of the instruments.

A role for the ribosome-associated complex in activation of the IRE1 branch of UPR.

The ubiquitous ribosome-associated complex (RAC) is a chaperone that spans ribosomes, making contacts near both the polypeptide exit tunnel and the decoding center, a position prime for sensing and coordinating translation and folding. Loss of RAC is known to result in growth defects and sensitization to translational and osmotic stresses. However, the physiological substrates of RAC and the mechanism(s) by which RAC is involved in responding to specific stresses in higher eukaryotes remain obscure.

The Long-Term Clinical Impact of Thoracic Endovascular Aortic Repair (TEVAR) for Advanced Esophageal Cancer Invading Aorta.
