A case report of a difficult dissection of the iliac vessels conducted by means of the harmonic scalpel during a kidney transplantation
2011
Background. The “difficult” preparation of iliac vessels in the kidney transplant recipient caused by a perivascular fibrosis with satellite lymphadenopathy is sometimes burdened by post-transplant complications (lymphocele, seroma and hematoma). Both iliac vascular adhesions and satellite lymphoadenopaty are often due to reiterate femoral cannulation aimed to hemodialysis. Patients and Methods: The case report concerns a 60 years old female uremic patient, on dialysis for about 4 years with perivascular fibrosis and pelvic lymphadenopathy caused by bilateral femoral artery catheterization. In the course of kidney transplant, preparation of the iliac vessels was performed by ultrasonic scal…
Adjustable tourniquet to manipulate pulmonary blood flow after Norwood operations
2000
Abstract Background . Survival after first-stage palliative Norwood operations for single ventricle with systemic outflow obstruction is mainly dependent on a balanced ratio of pulmonary blood flow to systemic blood flow. Here we report the clinical results using a modified technique that allows a controlled systemic-to-pulmonary shunt flow to prevent pulmonary overcirculation. Methods . From 1995 to 1998, of 26 infants undergoing first-stage palliative Norwood operations, 7 had placement of an adjustable tourniquet around a modified right Blalock-Taussig shunt. Results . Hospital survival was 20 of 26 patients (77%). All 7 patients in whom snaring of the shunt was indicated survived. Two p…
What Is the Role of Minimally Invasive Mitral Valve Surgery in High-Risk Patients? A Meta-Analysis of Observational Studies
2016
Background. Minimally invasive valve surgery is related to certain better postoperative outcomes. We aimed to assess the role of minimally invasive mitral valve surgery in high-risk patients. Methods. A systematic literature review identified eight studies of which seven fulfilled criteria for metaanalysis. Outcomes for a total of 1,254 patients (731 were conventional standard sternotomy and 523 were minimally invasive mitral valve surgery) were submitted to meta-analysis using random effects modeling. Heterogeneity and subgroup analysis with quality scoring were assessed. The primary end point was early mortality. Secondary end points were intraoperative and postoperative outcomes and long…
SYMPTOMATIC ACUTE MYOCARDIAL INFARCTION IN A PATIENT BEARER OF HEART TRANSPLANTATION FOLLOWING ISCHEMIC HEART DISEASE
2008
In 2005 Syeda et al. reported that the major factor limiting the long term of cardiac transplantation is the development of accelerated arteriosclerosis that occurs in the coronary arteries of the cardiac allograft. Transplant arteriosclerosis is characterized by diffuse, uniform, concentric narrowing of the artery by a fibrous proliferation of sub-intima cells. This atherosclerosis was estimate to occur in approximately 50% of patients by 5 years after transplantation. Unfortunately, as a consequence of cardiac denervation, symptoms are often atypical or completely absent. When these are present, the symptoms are those typical of effort angina. Very uncommon is the acute coronary syndrome.…
Organ Recovery Procedure in Donation After Controlled Circulatory Death with Normothermic Regional Perfusion: State of the Art
2020
The global shortage of organ donors will not be resolved solely by relying on donation after brain death. Expansion to use of donation after controlled circulatory death will be needed to address the shortfall of organs for transplantation. The processes of warm ischemia threaten the viability of organs obtained after controlled circulatory death, but these can be minimized by well-organized donation pathways and new techniques of in situ organ preservation, such as normothermic regional perfusion. The use of extracorporeal membrane oxygenation (ECMO) devices for normothermic regional perfusion in liver transplantation can help reduce rates of biliary complications, ischemic type biliary le…
Resection of Brainstem Cavernous Malformations: Pearls and Pitfalls for Minimizing Complications
2022
BACKGROUND: Surgical management of brainstem cavernous malformations (CMs) is a controversial topic in the field of neurosurgery. These lesions have a propensity to hemorrhage, thereby disrupting surrounding brainstem eloquence.METHODS: This article provides the personal reflections are senior author and a narrative literature review on resection of brainstem CMs.RESULTS: Here we discuss the indications for microsurgery, microsurgical techniques and nuances, and perioperative management considerations necessary to minimize complications during resection of brainstem CMs, which are lesions of venous origin.CONCLUSIONS: The natural history of the lesion, risk of future hemorrhage, and potenti…

Internal sphincterotomy reduces postoperative pain after Milligan Morgan haemorrhoidectomy
2009
Abstract Background Over the last few years, there has been increasing attention on surgical procedures to treat haemorrhoids. The Milligan-Morgan haemorrhoidectomy is still one of the most popular surgical treatments of haemorrhoids. The aim of the present work is to assess postoperative pain, together with other early and late complications, after Milligan-Morgan haemorrhoidectomy as we could observe in our experience before and after performing an internal sphincterotomy. Methods from January 1980 to May 2007, we operated 850 patients, but only 699 patients (median age 53) were included in the present study because they satisfied our inclusion criteria. The patients were divided into two…
Pre-core mutants of hepatitis B virus in patients receiving immunosuppressive treatment after orthotopic liver transplantation.
1996
Orthotopic liver transplantation (OLT) is a possible treatment for acute or chronic liver failure due to hepatitis B virus (HBV) infection, but reinfection of the graft can be a serious complication. The aim of this study was to monitor HBV markers, to analyse pre-core-/core-mutations as well as to identify the viral population causing reinfection after OLT, and to investigate the emergence or disappearance of these mutants in patients receiving immunosuppressive treatment. Fifty-four pre-and posttransplant serum samples of 17 patients were analysed. All patients underwent OLT for HBV-related liver disease and had HBV-DNA before and after OLT. Total DNA was extracted from all sera and a 240…
ATLAS TileCal Read Out Driver production
2007
The production tests of the 38 ATLAS TileCal Read Out Drivers (RODs) are presented in this paper. The hardware specifications and firmware functionality of the RODs modules, the test-bench and the test procedure to qualify the boards are described. Finally the performance results, the temperature studies and high rate tests are shown and discussed.
