Use of Marginal Donors in Kidney Transplantation: Our Experience
2006
The use of elderly donors has been advocated to expand the organ donor pool because of increased needs and the organ shortage. The aim of this study was to analyze whether the use of elderly donors and marginal kidneys affected the outcome of renal transplantations. Herein we presented data on 126 kidney transplantations performed from January 1996 to September 2003 using 32 marginal donors (group A) and 94 ideal donors (group B). We analyzed the medical and surgical complications and the graft survivals at a median follow-up of 18 months. Medical and surgical complications occurred in 22% and 5% versus 7% and 4% in groups A and B, respectively. The mean cold ischemia time and the mean age …
Should kidney allografts from old donors be allocated only to old recipients?
2020
Contains fulltext : 226016.pdf (Publisher’s version ) (Closed access) In several deceased donor kidney allocation systems, organs from elderly donors are allocated primarily to elderly recipients. The Eurotransplant Senior Program (ESP) was implemented in 1999, and since then, especially in Europe, the use of organs from elderly donors has steadily increased. The proportion of ≥60-year-old donors reported to the Collaborative Transplant Study (CTS) by European centers has doubled, from 21% in 2000-2001 to 42% in 2016-2017. Therefore, in the era of organ shortage it is a matter of debate whether kidney organs from elderly donors should only be allocated to elderly recipients or whether <65-y…
Orthotope arterialisierte Lebertransplantation bei Ratten mit Stenttechnik der supra- und infrahepatischen v. cava
2003
The aim of this study was to establish a liver transplant model with a reduced warm ischemic period between cold preservation and completed anastomosis. Male brown Norway rats were used. A cuff was fixed in the portal vein, stents were inserted in the A. hepatica, the suprahepatic and infrahepatic v. cava and in the bile duct. After cross clamping of the recipient liver, another stent, occluded by a small pin, was introduced in the recipient suprahepatic v. cava. After ligation of this recipient suprahepatic caval stent the recipient liver was removed and the cold prepared donor liver was pushed forward along the pin and both suprahepatic stents of recipient and donor were connected. Then c…
Lower extremity soft tissue defect reconstruction with the serratus anterior flap
2013
Reconstruction of limb-threatening lower extremity defects presents unique challenges. The selected method must provide adequate coverage of exposed bone, joints, and tendons while maximizing function of the limb. The traditional workhorse flaps, the free latissimus dorsi and rectus abdominis flaps, have been associated with donor site morbidity and bulkiness that can impair rehabilitation. We report a case series (n = 18) in which the free serratus anterior muscle flap and split thickness skin graft (STSG) was used for lower limb soft tissue coverage. Injuries were due to diabetes (9/18), trauma (7/18), and chronic venous stasis (2/18). A 94% flap survival rate was observed and all but one…
Anemia, heart failure and exercise training
2013
We read with interest the recent article by Wang et al. in which theauthors evaluated in anemic patients with heart failure whether exer-tionalperiodicbreathing influences rheological/hemodynamicfunctions[1]. For this purpose, the authors performed an incremental exercisetestusing a bicycle ergometer. In this regard, it has been generally assumedby some researchers, exercise physiologists and scientists that the incre-ment in blood hemoglobin (Hb) content is among the main hematolog-ical adaptations to endurance exercise training. This misconception isbased in the data published in diffe rent studies carried out severalyearsago [2].Inarecentmanuscript byBakeretal. [3],theauthorsdem-onstrated…
Formation of Venous Collaterals and Regeneration in the Donor Remnant Liver: Volumetric Analysis and Three-Dimensional Visualization
2009
Abstract Purpose We sought was to quantify and visualize the regeneration of the remnant liver after living donor liver transplantation using computed tomographic (CT) data. Methods For the evaluation of preoperative and follow-up data, we developed a software assistant that was able to compute the volume growth of the remnant liver and liver territories as well as visualize the individual growth of hepatic vessels over time. The software was applied to CT data of 20 donors who underwent right hepatectomy including the middle hepatic vein with at least 3 follow-up examinations in the first year after transplantation. Results After donation of a right lobe graft, the remnant liver regenerate…
Acellular dermal matrix in soft tissue reconstruction prior to bone grafting. A case report.
2010
When hard tissue augmentation is scheduled as a part of an oral rehabilitation, prior to the treatment, it is important to assess if the quality of the underlying gingiva at the recipient site can support the bone grafting procedure. The most frequent complication during autologous onlay grafts are wound dehiscences in the recipient site, so the integrity of soft tissues is a basic aspect of successful reconstructive and plastic surgical procedure. Connective tissue grafts can improve the quality and quantity of soft tissue in oral sites where a hard tissue reconstruction is going to take place. However, particularly when large grafts are harvested, the autogenous donor site can present sig…
Fat and liver transplantation: clinical implications
2018
Nonalcoholic steatohepatitis (NASH), with or without hepatocellular carcinoma, is a growing indication for liver transplantation (LT) worldwide, particularly in the Western world. Patients with NASH typically combine features of metabolic syndrome with cardiovascular comorbidities, which challenge pre-LT evaluation, surgical approaches, post-LT management, and outcomes. Post-LT survival in NASH patients is excellent, similar to that achieved with other indications, particularly in the absence of cardiovascular comorbidities. Although disease recurrence on the liver allograft is common, progression to advanced disease is uncommon, at least in the short term. Whether this holds true with long…
Anatomical Classification of the Peripheral Right Hepatic Duct: Early Identification of a Preventable Source of Morbidity and Mortality in Adult Live…
2008
Abstract Introduction The purpose of this study was to determine the impact of our classification on right graft adult live donor liver transplantation (ALDLT) outcomes. Methods Three-dimensional computed tomography (CT) reconstructions were used to classify the hilar and sectorial biliary anatomy of 71 consecutive live liver donors. Four possible clinical types were defined, based on the normal (N) or abnormal (A) features of the corresponding hilar/sectorial ducts: type I, N/N; type II, N/A; type III, A/N; and type IV, A/A. We subsequently performed an analysis of the operative outcomes based on the donor anatomy. Results Type I was encountered in 47.9% of cases, type II in 29.6%, type II…
Correlation of preoperative imaging characteristics with donor outcomes and operative difficulty in laparoscopic donor nephrectomy
2019
This study aimed to understand the relationship of preoperative measurements and risk factors on operative time and outcomes of laparoscopic donor nephrectomy. Two hundred forty-two kidney donors between 2010 and 2017 were identified. Patients' demographic, anthropomorphic, and operative characteristics were abstracted from the electronic medical record. Glomerular filtration rates (GFR) were documented before surgery, within 24 hours, 6, 12, and 24 months after surgery. Standard radiological measures and kidney volumes, and subcutaneous and perinephric fat thicknesses were assessed by three radiologists. Data were analyzed using standard statistical measures. There was significant correlat…
