- ASTS Position Statement On The Role Of COVID-19 Vaccination For Transplant Candidates And Recipients: The American Society of Transplant Surgeons continues to recommend routine vaccination for all organ recipients (along with timely boosters). It also recommends vaccines for those on the waiting list, if possible. Read more at the ASTS Position Statement.
- Kidney Transplants Increase Across All Populations Following Policy Changes: Changes to kidney allocation were made in March of this year with the goal of improving access to organs and equality. Recent data shows that kidney transplants for all age groups, blood types, CPRA, and diagnoses have increased following the implementation of these new policies. Read more at the UNOS News Section.
- Second Phase Of National DCD Procurement Collaborative Project Ready To Launch: UNOS has launched the second phase of a national collaborative improvement project to help organ procurement organizations (OPOs) identify and share effective practices related to recovery of donation after circulatory death (DCD) organs.

In the Spotlight: The Miami Transplant Institute (MTI)
David Rosenfeld, MD
An affiliation between Jackson Health System and UHealth-the University of Miami Health System.
In this month’s feature we learn from Drs. Ramona Nicolau-Raducu and Yehuda Raveh some of the characteristics that are unique about MTI.
The program is housed within the massive Jackson Memorial Hospital, one of the ten largest hospitals in the world with 2000 beds. Year in and out they are amongst the busiest abdominal programs with a US leading 472 kidneys transplanted in 2020, including a paired exchange program. MTI is also a front-runner in liver for the last 50 years, with over 4500 cases performed and 131 adult and 22 pediatric in 2020. Pancreas transplant is equally robust. For more than 20 years, and greater than 500 cases, a multidisciplinary team of experts at MTI has been treating thousands of children and adults with intestinal failure via Intestinal Rehabilitation or the Intestinal/Multivisceral Transplant Program, with outcomes well above national averages. Along with deceased donor intestinal (~5 cases/year) and multivisceral transplants (~10-15 cases/year), autologous transplant procedures are offered.
MTI became in recent years a bloodless center for Jehovah Witness transplants with a meticulous selection process for Jehovah’s Witness liver candidates. A bloodless protocol has been established of using factor concentrates, hemopure (bovine hemoglobin-based oxygen carrying solution) autotransfusion and cell saver.
In February 2020 the national organ allocation system transformed from donor service area-based to an acuity circles-based model. Due to its unique geography near the tip of the Florida peninsula, the new system limits organ allocation. As a result, use of DCD and other extended criteria grafts for liver or liver-kidney have increased, currently approximately 25% of liver grafts. In addition, patients listed for multivisceral transplantation are especially impacted by this change. Due to specific quality requirements for suitable donors, which are typically younger and non-obese, the available donor pool is considerably smaller. Previously these patients were assigned amongst the highest status levels on the liver match run, but the current allocation model routinely prioritizes a suitable donor to a liver alone candidate that does not have the same size and quality limitations but has a high “competitive” MELD score.
The Abdominal Transplant Anesthesia Fellowship at Jackson Memorial Hospital was created in 2006 by Dr. Ernesto Pretto, Chief, Division of Transplant Anesthesia and is one of the largest in the nation with 4 fellows/year. Transplant anesthesiology fellowships are non-ACGME accredited and are generally less popular for board eligible/certified US anesthesiology graduates, however this program has thrived through selecting highly qualified foreign graduates to consistently fill its positions. They have graduated a remarkable 50 transplant fellows in the last 15 years (10% US graduates and 90% International).
Many thanks to Drs. Nicolau-Raducu and Yahuda for sharing details of their program.

Living donor liver transplantation for hepatocellular carcinoma beyond the Milan criteria: outcome of expanded criteria in tumor size (Liang et al. BMC Surg. 2021)
Since 1996 Milan criteria for hepatocellular carcinoma has been used to guide liver transplantation to those who would benefit most and restrict deceased donor organs to those with the highest likelihood of survival. Living donor transplants tend to be directed to individuals who do not meet this criteria if the donor and recipient understand the potential risk. Liang et al. out of Taiwan report on 155 patients, 78 of which were beyond Milan criteria for tumor size or number found similar outcomes and recurrence rates. They propose a new criteria: maximum tumor size <= 6cm and total tumor size < 10cm.
Challenges and opportunities for treating intrahepatic cholangiocarcinoma (Serifis et al. Hepat Med. 2021)
There is potential to expand transplant criteria for living donor liver transplantation with less stringent criteria for directed donors. In addition to the potential for an expanded hepatocellular carcinoma guideline, cholangiocarcinoma is another disease process with historically poor outcomes which may be treated by transplantation with strict selection criteria, operative staging, and neoadjuvant therapy.
Liver transplant outcomes after ex vivo machine perfusion: A meta-analysis (Liew et al. Br J Surg. 2021)
Ex-vivo machine perfusion – Meta-analysis included 34 articles with odds ratios favoring hypothermic machine perfusion over static cold storage. Findings include: decreased early graft dysfunction, ischemic cholangiopathy, non-anastamotic strictures and graft loss. Machine perfusion was associated with shorter length of stay. Normothermic perfusion is associated with reduced graft injury.
Machine perfusion organ preservation: Highlights from the American Transplant Congress 2021 (Pavan-Guimaraes et al. Artif Organs. 2021)
At the American Transplant Congress (June 2021) 33 abstracts on machine perfusion were presented including heart, lung, liver and kidney. Machine perfusion may become gold standard in the future as innovation and advancement bring down costs and improve outcomes.
SATA Committee’s Update
Yong G Peng, MD, PhD
We caught up with the Quality and Standards Committee Chair, Dr. Adrian Hendrickse (Associate Professor, University of Colorado). The members of the committee have been working hard on several surveys. The first survey, led by Dr. Cara Crouch (Assistant Professor, University of Colorado), looked at Adult Liver Transplant Anesthesiology practice patterns across the US. Their research was published in the Journal of Clinical Transplantation. (Crouch et al. Clin Transplant. 2021)
Additionally, a smaller sub-committee of members are interested in living donor liver transplantation (LDLT) status. The group, headed by Dr. Tetsuro Sakai (SATA president), has investigated LDLT programs across the US. They have submitted their findings in an abstract to the 2022 IARS/AUA and ILTS meetings. They plan to prepare a manuscript of their findings. The committee has worked closely with the Korean Society of Anesthesiologists in an effort to write a collaborative review of LDLT practice, which they are planning to submit to Clinical Transplantation.
The Q&S committee members have worked on several other research projects, including similar survey-based methods, investigating different organ transplantation services, and pursuing the development of SATA endorsed guidelines for our subspecialty.
