The prognosis for patients with cardiac impairment due to AL-amyloid deposition and severe cardiac insufficiency is poor, with a survival median in the order of months. The classical treatment of AL-amyloidosis in combination with cardiac insufficiency is very poorly tolerated and the treatment of such patients is associated with considerably higher mortality than among other patients with AL-amyloidosis. If, however, patients with an isolated or another dominating cardiac impairment, without severe damage to other organs and tissues, have a heart transplant performed, their cardiovascular condition will significantly improve as a result, along with their ability to tolerate any kind of treatment for AL-amyloidosis including that using high-dose chemotherapy with a transplant of autologous hematopoietic stem cells...

The use of free fat pads is effective for repairing pulmonary air leakage clinically. It has been reported that the free pericardial fat pad (FPFP) used to repair the lung remained at the transplanted site in many cases according to images. However, no information is available regarding what type of actual changes these free fat pads with no blood supply undergo. We examined changes in an FPFP that was used to repair pulmonary air leakage in a patient who underwent a surgery for lung cancer 1 year ago. Although the FPFP transplanted to the pleural defect remained without deforming morphologically in this patient 1 year after the first surgery, pathological findings suggested fat necrosis surrounded by fibrous tissue...

Chronic lymphedema is caused by an impairment of the lymphatic system due to primary or secondary causes. Vascularized lymph node transplantation (VLNT) is currently the most promising and frequently used technique besides lymphaticovenous anastomosis. However, the vessel anatomy in the lateral thoracic region is sometimes quite variable. Based on our experiences with vascular anatomical inconstancy in the lateral thoracic region, we planned a lateral intercostal artery perforator flap for VLNT in a female patient with chronic stage II lymphedema of both legs after cervical cancer treatment...

BACKGROUND: The clinical unpredictability of autologous fat grafting originates partially from the unique characteristics of adipose tissue. Evidences of adipose remodeling toward browning (developing of brown-like adipocytes in white adipose tissue) in response to trauma are emerging. With regard to fat grafting surgery procedure by which adipose tissue depots are directly and ubiquitously traumatized, whether it affect adipose phenotype change toward browning has not been previously reported...

Loss of photoreceptors and other retinal cells is a common endpoint in retinal degenerate (RD) diseases that cause blindness. Retinal transplantation is a potential therapy to replace damaged retinal cells and improve vision. In this study, we examined the development of human fetal retinal sheets with or without their retinal pigment epithelium (RPE) transplanted to immunodeficient retinal degenerate rho S334ter-3 rats. Sheets were dissected from fetal human eyes (11-15.7 weeks gestation) and then transplanted to the subretinal space of 24-31 d old RD nude rats...

Pancreatic islet transplantation to reduce hyperglycemia is highly successful in rodents with chemically-induced diabetes. The most common transplantation site in experimental islet transplantation is the kidney capsule. However, as less is known about the interaction of pancreatic islets with blood constituents, it also makes sense to utilize the portal vein approach in experimental islet transplantation. This protocol demonstrates an intraportal islet transplantation technique in NMRI nude mice. Streptozotocin (180 mg/kg) is injected intraperitoneally to induce hyperglycemia in recipient mice...

Case summary: A 10-year-old spayed female American Shorthair cat underwent renal transplantation due to worsening chronic kidney disease secondary to polycystic kidney disease. During transplantation, the right kidney grossly appeared to be more diseased than the left and was firmly adhered to the surrounding tissues. An intraoperative fine-needle aspirate of the right native kidney revealed inflammatory cells but no evidence of neoplasia. To create space for the allograft, a right nephrectomy was performed...

For patients at risk of premature ovarian failure with cancer treatment, it is an important option to re-implant the ovarian tissue (OT) after cryopreservation to preserve endocrine function and fertility. With this technique, about 30% of pregnancy success rate and about 90 live births have been reported to date. However, there has been no case report of successful in vitro fertilization (IVF) and embryo transfer (ET) with oocytes collected from transplanted cryopreserved OT in Korea. We report a 30-year old woman with rectal cancer who underwent IVF and ET after cryopreserved OT thawing and re-implantation...

For the year 2017, more than 21,000 published references can be found in PubMed when entering the search term "cardiac surgery". This review focusses on conventional cardiac surgery, considering the new interventional techniques only if they were directly compared to classic techniques but also entails aspects of perioperative intensive care management. The publications last year provided a plethora of new and interesting information that helped to quantify classic surgical treatment effects and provided new guidelines for the management of structural heart disease, which made comparisons to interventional techniques easier...
