Here, we reported our clinical application of ureterorenoscope (URS) and flexible URS lithotripsy in stone removal on 10 cases of excised living donor kidney graft. After the extraction of donor kidney by retroperitoneal laparoscopy, the donor graft was perfused with 4 °C HCA solution. Calculus between 2-4 mm were removed intact with lithotomy forceps under direct vision of URS. Larger calculi of >4 mm were fractured with flexible URS combining holmium laser lithotripsy. Fragments of the calculus were extracted with basket extractor and lithotomy forceps...

Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is an option for mechanical support for patients with postcardiotomy cardiogenic shock (PCS). However, the use of VA-ECMO in patients suffering from aortic disease with PCS has not been greatly reported. This is a retrospective review of adult patients undergoing aortic surgery who received VA-ECMO support to treat refractory PCS from August 2009 to May 2016. A total of 36 patients who underwent aortic surgery with VA-ECMO support for refractory PCS were included...

BACKGROUND: Femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) is widely used to maintain blood flow in patients with cardiogenic shock. However, retrograde blood flow increases left ventricular (LV) afterload during femoral VA-ECMO. Additional support by means of an intraaortic balloon pump (IABP) alleviates LV afterload but is associated with significant adverse events. We previously developed a system for rotational speed modulation in synchrony with the native cardiac cycle, for use with implantable continuous-flow LV assist devices...

The management of overdoses of cardioactive medications in the emergency department can be challenging. The reversal of severe toxicity from one or more types of cardioactive medication may fail maximal medical therapies and require extreme invasive measures such as transvenous cardiac pacing and extracorporeal life support. We present a case of massive diltiazem and metoprolol overdose refractory to maximal medical therapy, including intravenous calcium, glucagon, vasopressors, high dose insulin, and lipid emulsion...

OBJECTIVE: Coronary artery bypass grafting (CABG) remains the gold standard for complex revascularisation in multivessel disease. The concept of the minimally invasive extracorporeal circulation circuit (MiECC) was introduced to minimise pathophysiological side effects of conventional extracorporeal circulation. This study presents early and long-term outcomes after CABG with use of MiECC in a single-centre consecutive patient cohort. METHODS: From 1 January 2005 to 31 December 2010, 2130 patients underwent isolated CABG with MiECC at our centre...

BACKGROUND: Cardiac surgery is, by definition, a "non-physiologic" intervention associated with systemic adverse effects. Despite advances in surgical technique, cardiopulmonary bypass (CPB) technology as well as anaesthesia management and patient care, there is still significant morbidity and subsequent mortality. AIM: We consider that the contemporary demand for further improving patient outcome mandates the upgrade from optimal perfusion during the procedure as the gold standard to the concept of a "more physiologic" cardiac surgery...

BACKGROUND: Ex vivo lung perfusion (EVLP) enables assessment of marginal donor lungs for transplantation, with similar clinical outcomes to conventional lung transplantation. We investigated whether cell death-related proteins in the EVLP perfusate could predict primary graft dysfunction (PGD) after transplantation. METHODS: M30 (indicating epithelial apoptosis), M65 (indicating total epithelial cell death), and high mobility group box 1 (HMGB-1, related to cell death and inflammation) protein levels in EVLP perfusate were measured by enzyme-linked immunosorbent assay and correlated with clinical outcomes...

Calcium channel blockers (CCBs) are responsible for a substantial portion of the mortality associated with cardiovascular medication overdose cases. Amlodipine, a dihydropyridine CCB, can cause prolonged hypotension in overdose. This report describes a severe amlodipine overdose case that was refractory to multiple therapeutic approaches. A 53-year-old male presented after ingesting eighty 10 mg amlodipine tablets in a suicide attempt. The patient was initially managed with calcium boluses, glucagon, multiple vasoactive agents, lipid emulsion infusions and hyperinsulinemic euglycemic therapy...

In patients under extracorporeal membrane oxygenation (ECMO) support requiring renal replacement therapy or plasmapheresis, connecting such extracorporeal therapy device to the ECMO circuit provides many advantages compared with central venous catheterization. However, high pressures of the ECMO circuit limit the usefulness of this technique. We propose a new approach to connect extracorporeal therapy lines to the ECMO circuit. Inlet line is connected to the oxygenator, and outlet line is connected either to the femoral artery antegrade perfusion cannula in case of venoarterial ECMO or to the lateral vent of the return cannula in case of venovenous ECMO...

Maintaining the viability of organs from donors after circulatory death (DCD) for transplantation is a complicated procedure, from a time perspective in the absence of appropriate organizational capabilities, that makes such transplantation cases difficult and not yet widespread in Poland. We present the procedural preparation for Poland's first case of organ (kidney) transplantation from a DCD donor in which perfusion was supported by extracorporeal membrane oxygenation (ECMO). Because this organizational model is complex and expensive, we used advanced high-fidelity medical simulation to prepare for the real-life implementation...

INTRODUCTION: Hepatoblastoma with tumour thrombi extending into inferior-vena-cava and right atrium are often unresectable with an extremely poor prognosis. The surgical approach is technically challenging and might require major liver resection with vascular reconstruction and extracorporeal circulation. However, which is the best surgical technique is yet unclear. PRESENTATION OF CASE: A 11-months-old boy was referred for a right hepatic lobe mass(90×78mm) suspicious of hepatoblastoma with tumoral thrombi extending into the inferior-vena-cava and the right atrium, bilateral lung lesions and serum alpha-fetoprotein level of 50...

Monitoring brain integrity and neuro-cognitive function is a new and important target for the management of a patient treated with extracorporeal membrane oxygenation (ECMO), in particular because of the increasing awareness of cerebral abnormalities that may potentially occur in this setting. Continuous regular monitoring, as well as repeated assessment for cerebral complications has become an essential element of the ECMO patient management. Besides well-known complications, like bleeding, ischemic stroke, seizures, and brain hypoperfusion, other less defined yet relevant injury and clinical manifestations are increasingly reported and impacting on ECMO patient prognosis at short term...

BACKGROUND: Over the last two decades, intraperitoneal chemotherapy has been found to have activity for select subgroups of patients with carcinomatosis from colon, ovarian, appendiceal, and recently, gastric origins. However, there is little data to support an aggressive surgical approach of cytoreduction (debulking) and hyperthermic intraperitoneal perfusion with chemotherapy (HIPEC) for patients with gastric cancer and positive cytology or carcinomatosis. The morbidity and mortality rates of cytoreduction and HIPEC, in combination with gastrectomy, are significant and the survival rates of this approach may not extend beyond that of treatment with systemic chemotherapy...

BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...

Blood oxygenized by veno-arterial extracorporeal membrane oxygenation (ECMO) can be returned to the aorta (central cannulation) or to peripheral arteries (axillar, femoral). Hemodynamic effects of these cannulation types were analyzed in a mock loop with an aortic model representative of normal anatomy and compliance under physiological pressures and flow rates. Pressures, flow rates, and contribution of ECMO flow to total flow as a measure of oxygen supply were monitored in the carotids. Steady or pulsatile ECMO flow, residual or no cardiac output, and intraaortic balloon pump counterpulsation were tested as independent factors...

Sergey Brukhonenko was a prominent Soviet physician-scientist who from 1922 to 1924 developed a methodology for perfusing a canine head and keeping it alive using the first extracorporeal life support device he created called "Autojector." From 1926 to 1927, in collaboration with surgeon Nikolay Terebinsky, he performed a series of perfusion experiments of the entire canine body using a more advanced model of Autojector. Subsequently, Brukhonenko concluded the possibility of extending this methodology to heart surgery...

The total circulatory arrest (CA) is necessary to achieve optimal surgical conditions in certain aortic pathologies, especially in those affecting the ascending aorta and aortic arch. During this procedure it is necessary to protect all the organs of ischemia, especially those of the central nervous system and for this purpose several strategies have been developed. The first and most important protective method is systemic hypothermia. The degree of hypothermia and the route of application have been evolving and currently tend to use moderate hypothermia (MH) (20...
