Rescue Arterial Revascularization Using Cryopreserved Iliac Artery Allograft in Liver Transplant Patients.

Objectives: Management of hepatic arterial complications after liver transplant remains challenging. The aim of our study was to assess the efficacy of rescue arterial revascularization using cryopreserved iliac artery allografts in this setting.

Materials And Methods: Medical records of patients with liver transplants who underwent rescue arterial revascularization using cryopreserved iliac artery allografts at a single institution were reviewed.

Cryopreserved iliac artery allograft for primary arterial revascularization in adult liver transplantation.

Arterial allograft represents a material of choice for primary arterial revascularization in liver transplantation (LT) when interposition of a vascular conduit is required. In case of non-availability of such graft, the use of cryopreserved vessels should be an interesting option. Three patients were grafted using a cryopreserved iliac artery allograft (CIAA) previously harvested and stored at -140°C in a tissue bank.

Long-term persistent lymphopenia in hematopoietic stem cell donors after donation for donor lymphocyte infusion.

Objectives: To analyze the consequences of lymphocyte donations on lymphopoiesis in donors having previously undergone hematopoietic stem cell collection for allogeneic stem cell transplantation.

Methods: Repeated analysis of leukocyte subsets in the peripheral blood of 76 hematopoietic stem cell donors undergoing lymphocyte donation(s) for DLI.

Results: Grade I/II lymphopenia was present in 22 donors (29%) just before first apheresis for lymphocyte collection, demonstrating that former stem cell donation induced prolonged lymphopenia in a subset of donors.
