Central and Peripheral Arterial Diseases in Chronic Kidney Disease: Conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference.

Kidney Int 2021 May 4. Epub 2021 May 4.

Department of Cardiology I: Coronary and Peripheral Vascular Disease, Heart Failure, Münster University Hospital, Münster, Germany. Electronic address:

Chronic kidney disease (CKD) affects about 10% of all populations worldwide, with about 2 million people requiring dialysis. Although patients with CKD are at high risk of cardiovascular disease (CVD) and events, they are often underrepresented or excluded in clinical trials, leading to important knowledge gaps about how to treat these patients. KDIGO (Kidney Disease: Improving Global Outcomes) convened the fourth Clinical Controversies Conference on the Heart, Kidney and Vasculature in Dublin, Ireland, in February 2020, entitled "Central and Peripheral Arterial Diseases in Chronic Kidney Disease.

Abstract: Vascular smooth muscle cell (VSMC) dysfunction is the main cause of aortic dissection (AD). In this study, we focused on the role and mechanism of miR-4787-5p in regulating VSMC apoptosis. RT-qPCR was used to detect the expression of miR-4787-5p in aorta tissues of AD (n=10) and normal aortic tissues of donors (n=10). Read More

Anatomic feasibility of off-the-shelf thoracic single side-branched endograft in patients with blunt traumatic thoracic aortic injury.

J Vasc Surg 2021 May 3. Epub 2021 May 3.

Department of Surgery, Division of Vascular Surgery, University of California-Davis Medical Center, Sacramento, CA.

Objectives: The advent of thoracic single side-branched endograft (TSSBE) provides a treatment option to obviate the need for open cervical debranching of the left subclavian artery (LSA), thereby enabling total endovascular incorporation of the LSA during thoracic endovascular aortic repair (TEVAR). In a previous study in patients with type B aortic dissection who required zone 2 TEVAR, anatomic feasibility of this device has been demonstrated to range between 28% and 35%, suggesting limited applicability of currently available designs. The objective of this study was twofold: (1) to evaluate the anatomic feasibility of TSSBE in blunt traumatic thoracic aortic injury (BTAI) patients who would require LSA revascularization; and (2) to describe the anatomical characteristics of the supra-aortic arch branches that can be used to improve future device design.

Impact of ABO blood group on bleeding complications after surgery for acute type A aortic dissection.

Blood Coagul Fibrinolysis 2021 Jun;32(4):253-258

Department of Cardiothoracic Surgery, Clinical Sciences, Lund University, Skane University Hospital, Lund, Sweden.

Excessive bleeding is a serious complication associated with impaired survival after surgery for acute type A aortic dissection (ATAAD). Different ABO blood groups are associated with variable levels of circulating von Willebrand factor and therefore potentially altered risks of surgical haemorrhage. The current study aimed to assess the impact of blood group on bleeding complications after ATAAD surgery. Read More

Impact of Lymphocyte-Related Blood Parameters on Short- and Long-Term Outcomes of Patients Undergoing Thoracic Endovascular Aortic Repair.

Angiology 2021 May 6:33197211012514. Epub 2021 May 6.

Department of Cardiology, Guangdong Cardiovascular Institute, Guangdong Provincial Key Laboratory of Coronary Heart Disease Prevention, Guangdong Provincial People's Hospital, Guangdong Academy of Medical Sciences, Guangzhou, China.

Lymphocyte-related blood parameters (LRBP), including neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio, and lymphocyte-monocyte ratio, could reflect a patient's overall inflammatory status. We aimed to clarify the association between preoperative LRBP and outcomes of type B aortic dissection (TBAD) patients undergoing thoracic endovascular aortic repair (TEVAR). A total of 841 patients were enrolled from 2010 to 2017. Read More

Short- and long-term outcomes of aortic root-sparing repair and replacement in acute type A aortic dissection repair.

Asian Cardiovasc Thorac Ann 2021 May 4:2184923211015087. Epub 2021 May 4.

Aortovascular Surgery, Barts Heart Centre, St. Bartholomew's Hospital, London, UK.

Acute type A aortic dissection is a surgical emergency with a high mortality rate if left untreated. Management of the aortic root in this setting constitutes an intricate decision-making framework, further complicated by the emergent nature of the dissection. There exists much controversy regarding pursuit of the aggressive aortic root replacement versus a conservative root-sparing repair, alongside considerations for valve-sparing root replacement.

"Millefeuille Technique" by Using Excised Intimal Layers in Repair of Type A Aortic Dissection.

Heart Lung Circ 2021 Apr 30. Epub 2021 Apr 30.

Nagoya University Graduate School of Medicine, Department of Cardiac Surgery, Nagoya, Aichi, Japan.

Surgical outcomes for acute Type A aortic dissection (AAD) have dramatically improved in recent years due to prompt diagnosis, improved surgical technique and perioperative management. A single needle hole can become a new entry point in AAD cases with such a fragile wall, so a mixed technique using minimal surgical stitches and glue is required for a good outcome. The 'Millefeuille' technique involves multiple layers with a prosthetic graft, intimal layer, additionally inserted surplus intimal layer with BioGlue, adventitial layer, and felt. Read More

4-Year Results of the Bolton Relay Proximal Scallop Endograft in the Management of Thoracic and Thoraco-Abdominal Aortic Pathology with Unfavourable Proximal Landing Zone.

J Vasc Surg 2021 Apr 30. Epub 2021 Apr 30.

Imperial Vascular Unit, Imperial College Healthcare NHS Trust, London, UK; Department of Interventional Radiology, Imperial College Healthcare NHS Trust, London, UK. Electronic address:

Introduction: Thoracic endovascular aortic repair with a scallop design (scallop-TEVAR) is a useful treatment strategy to extend the proximal landing zone (PLZ), whilst maintaining perfusion to one or more of the supra-aortic trunks when treating aortic pathology with an unfavourable PLZ. The durability of this approach with the Bolton Relay scallop endograft (Terumo Aortic, Sunrise, Florida, United States) has not been established.

Methods: A retrospective review of prospectively collected data on consecutive patients that received scallop-TEVAR in zones 0-2 at a tertiary aortic unit was undertaken. Read More

Comparison of diametric and volumetric changes in Stanford type B aortic dissection patients in assessing aortic remodeling post-stent graft treatment.

Quant Imaging Med Surg 2021 May;11(5):1723-1736

Department of Biomedical Engineering, Faculty of Engineering, University of Malaya, 50603 Kuala Lumpur, Malaysia.

Background: The study aims to analyze the correlation between the maximal diameter (both axial and orthogonal) and volume changes in the true (TL) and false lumens (FL) after stent-grafting for Stanford type B aortic dissection.

Application of deep hypothermic circulatory arrest in open left chest aortic aneurysm repair.

J Thorac Cardiovasc Surg 2021 Mar 31. Epub 2021 Mar 31.

Division of Thoracic and Cardiovascular Surgery, Department of Surgery, University of Florida, Gainesville, Fla. Electronic address:

Objectives: Deep hypothermic circulatory arrest (DHCA) is often required for patients undergoing repair of descending thoracic aortic aneurysm (DTAA) or thoracoabdominal aortic aneurysm via left thoracotomy when proximal crossclamping is not feasible or when aneurysmal disease extends into the transverse aortic arch. Historical literature suggests higher complications rates due to the technical complexity of this approach; we examined outcomes with this approach at our center.

Methods: Between January 2008 and May 2018, 84 patients with DTAA or Crawford extent I thoracoabdominal aortic aneurysm underwent open repair. Read More
