Vacuum-Assisted Thrombo-Aspiration for Paradoxical Embolism in Left Renal Artery: A Case Report and Literature Review.

Paradoxical embolism through the foramen ovale is a rare and devastating event requiring urgent treatment. Herein, we present the case of a 23-year-old male who presented with a pulmonary embolism complicated by a left renal artery paradoxical embolism. Urgent vacuum-assisted thrombo-aspiration restored normal perfusion of the left kidney within 5 hours.

Quality assurance in surgical trials of arteriovenous grafts for haemodialysis: A systematic review, a narrative exploration and expert recommendations.

Background: Introducing new procedures and challenging established paradigms requires well-designed randomised controlled trials (RCT). However, RCT in surgery present unique challenges with much of treatment tailored to the individual patient circumstances, refined by experience and limited by organisational factors. There has been considerable debate over the outcomes of arteriovenous grafts (AVG) compared to AVF, but any differences may reflect differing practice and potential variability.

Incidental appendicectomy in pancreas transplantation: A single-center study.

Background: Appendicitis in pancreatic transplant recipients can be challenging to diagnose and manage. Incidental appendicectomy (IA) during pancreas transplantation obviates the risk of appendicitis but potentially at the cost of increased operating time or early post-operative complications. This study reviewed the value of IA at a single center.

British Transplantation Society guidelines on abdominal organ transplantation from deceased donors after circulatory death.

The British Transplantation Society (BTS) 'Guideline on transplantation from deceased donors after circulatory death' has recently been updated and this manuscript summarises the relevant recommendations in abdominal organ transplantation from Donation after Circulatory Death (DCD) donors, encompassing the chapters on liver, kidney, pancreas and islet cell transplantation.

Quality assurance in surgical trials of arteriovenous grafts for haemodialysis: protocol for a systematic review.

Introduction: Decisions regarding the optimal vascular access for haemodialysis patients are becoming increasingly complex, and the provision of vascular access is open to variations in systems of care as well as surgical experience and practice. Two main surgical options are recognised: arteriovenous fistula and arteriovenous graft (AVG). All recommendations regarding AVG are based on a limited number of randomised controlled trials (RCTs).

Changing landscape in living kidney donation in Greece.

Patients with end-stage renal disease in Greece are facing long waiting times to receive a kidney transplant from a deceased donor. Living kidney donation offers a valuable alternative that provides optimal outcomes and significantly expands the donor pool but still remains relatively underutilised. Developments around the world in the field of kidney transplantation mandate a change in current practice to include additional options for living donation through paired exchange, antibody-incompatible transplantation and other strategies, following careful consideration of the cultural and ethical factors involved in these complex clinical decisions.

Recruitment into randomised trials of arteriovenous grafts: A systematic review.

Although randomised controlled trials (RCT) are considered the optimal form of evidence, there are relatively few in surgery. Surgical RCT are particularly likely to be discontinued with poor recruitment cited as a leading reason. Surgical RCT present challenges over and above those seen in drug trials as the treatment under study may vary between procedures, between surgeons in one unit, and between units in multi-centred RCT.

Crisis Preparedness: A Systems-Based Framework for Avoiding Harm in Surgery.

Background: Highly performing healthcare organizations benefit from robust failure management systems. This involves the ability to respond and recover from critical events, as well avoiding harm in the first place (crisis preparedness). Currently, the surgical community may lack an integrated toolbox for crisis readiness.

How crises work: A model of error cause and effect in surgical practice.

Introduction: Surgical crises have major consequences for patients, staff and healthcare institutions. Nevertheless, their aetiology and evolution are poorly understood outside the remit of root-cause analyses.

Aims: To develop a crisis model in surgery in order to aid the reporting and management of safety critical events.

Crisis Containment: Tools for Harm Mitigation in Surgery.

Background: Surgical crises represent unrecognized opportunities for improving patient safety and adding value in healthcare. The first step in a crisis response is to contain and mitigate harm. While the principles of damage control are well established in surgery, methods of containing harm on broader clinical and organizational levels are not clearly defined.

Outcomes of pregnancy in simultaneous pancreas and kidney transplant recipients: A single-center retrospective study.

Simultaneous pancreas and kidney (SPK) transplantation, in uremic women with insulin-dependent diabetes, increases the chance of a successful pregnancy and minimizes the risk to infants. The aim of this study was to document pregnancy and explore the challenges in this cohort of women. Retrospective analysis of women who underwent pancreas transplantation between January 1, 1998 and 8 January, 2019 was conducted.

Avoid, Trap, and Mitigate: Development of an Evidence-Based Crisis Management Framework in Surgery.

Background: Increasingly, surgeons are adopting broader roles in emergency response, on both clinical and executive levels. These have highlighted the need to develop healthcare-specific crisis management systems. Cross-professional research between safety-critical industries is a valuable method for learning crisis control.

The implications of donor-recipient size mismatch in renal transplantation.

Introduction: Transplanting kidneys small for recipient's size results in inferior graft function. Body surface area (BSA) is related to kidney size. We used the BSA index (BSAi) (Donor BSA/Recipient BSA) to assess whether the renal graft size is sufficient for the recipient.

Outcomes after simultaneous pancreas-kidney transplantation from donation after circulatory death donors: A UK registry analysis.

There are concerns that simultaneous pancreas-kidney (SPK) transplants from donation after circulatory death (DCD) donors have a higher risk of graft failure than those from donation after brain death (DBD) donors. A UK registry analysis of SPK transplants between 2005 and 2018 was performed. Pancreas survivals of those receiving organs from DCD or DBD donors were compared.

Weight trends in living kidney donors suggest predonation counselling alone lacks a sustainable effect on weight loss: a single centre cohort study.

Living kidney donors are at risk of long-term end-stage renal disease, and obesity is an independent risk factor. In our centre, predonation counselling of obese donors concentrates on lifestyle modifications, particularly weight loss and exercise. Whether these recommendations have a sustainable effect after donation remains unknown.

Hypoperfusion warm ischaemia time in renal transplants from donors after circulatory death.

Background: The donor hypoperfusion phase before asystole in renal transplants from donors after circulatory death (DCD) has been considered responsible for worse outcomes than those from donors after brain death (DBD).

Methods: We included 10 309 adult renal transplants (7128 DBD and 3181 DCD; 1 January 2010-31 December 2016) from the UK Transplant Registry. We divided DCD renal transplants into groups according to hypoperfusion warm ischaemia time (HWIT).

UK renal transplant outcomes in low and high BMI recipients: the need for a national policy.

Introduction: We assessed the effect of recipient body mass index (BMI) on the outcomes of renal transplantation and the management of obese patients with end-stage renal disease across the UK.

Methods: We analyzed data of 25539 adult renal transplants (2007-2016) from the UK Transplant Registry. Patients were divided in BMI groups [underweight: < 18.

An Implanted Blood Vessel Support Device for Arteriovenous Fistulas: A Randomized Controlled Trial.

Rationale & Objective: Reducing turbulent blood flow through dialysis arteriovenous fistulas (AVFs) and radial stretching of their venous wall may attenuate hyperplasia and stenosis and improve AVF outcomes in hemodialysis patients. The goal of this study was to evaluate the safety and efficacy of the VasQ implant, which intervenes on these mechanisms by physically supporting the surgical arteriovenous anastomosis.

Study Design: Prospective, randomized, controlled, multicenter study.

Outcomes in Third and Fourth Kidney Transplants Based on the Type of Donor.

Background: An increasing number of patients are requiring multiple retransplants. We assessed outcomes of third and fourth kidney transplants, to aid decision making on the most suitable donor type.

Methods: Data were collected retrospectively for 2561 transplants, including 69 third and 8 fourth, performed from 2000 to 2017.

First UK case report of kidney transplantation from an HIV-infected deceased donor to two HIV-infected recipients.

Kidney transplantation is now considered the treatment of choice for many human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). Graft survival rates using HIV-negative donors and carefully selected HIV-positive ESRD patients are similar to those observed in HIV-uninfected kidney transplant recipients. To address the relative shortfall in donated organs it has been proposed that organs from HIV-infected deceased donors might be allocated to HIV-infected patients on the transplant waiting list.

A Re-evaluation of Discarded Deceased Donor Kidneys in the UK: Are Usable Organs Still Being Discarded?

Background: A significant proportion of procured deceased donor kidneys are subsequently discarded. The UK Kidney Fast-Track Scheme (KFTS) was introduced in 2012, enabling kidneys at risk of discard to be simultaneously offered to participating centers. We undertook an analysis of discarded kidneys to determine if unnecessary organ discard was still occurring since the KFTS was introduced.
