Living related liver transplantation offers several advantages in comparison to transplantation of cadaver organs. To achieve maximal donor safety evaluation, selection criteria and complications of the donor operation were retrospectively analyzed in living donors of segmental liver transplants. Seventy-three liver donor candidates were evaluated between October 1991 and June 1994. The median age of 42 mothers and 31 fathers was 31 years (range, 19-50 years). The median volume of the left lateral liver lobe comprised 230 ml (100-350 ml). Twenty-four of 73 (33%) donor candidates were not accepted for living donation. Rejection was due to unsuitability of the donor's liver as a graft (n = 13) or due to an increased risk for living donation (n = 11). Of 35 living donations performed so far, one was a full left hemihepatectomy and 34 were left lateral segmentectomies. The length of the donor operation was, on average, 4.3 hr. No heterologous blood was needed. Postoperative complications included death due to pulmonary embolism (n = 1), seizure due to a previously undiagnosed ependymoma (n = 1), bile duct injury (n = 1), incisional hernia necessitating late revision (n = 2), and duodenal ulcer (n = 2). Long-term follow-up revealed no persistent complications. Using our standardized protocol, 33% of young, presumably healthy donor candidates were rejected for living donation.

Patients with neurofibromatosis 1 (NF1) are predisposed to develop central nervous system tumors, due to the loss of neurofibromin, an inactivator of proto-oncogene Ras. However, to our knowledge, only three cases of ependymomas with NF1 have been reported in the literature. The authors present a case of NF1 patient with a spinal cord ependymoma. She was referred for about half a year history of increasing numbness that progressed from her fingers to her entire body above the bellybutton. Magnetic resonance imaging revealed a relative-demarcated, heterogeneously enhanced mass lesion accompanied by perifocal edema in C5-7 level, a left-sided T11 spinous process heterogeneously enhanced mass in soft tissue, intervertebral disk hernia in L2-5 level, and widespread punctum enhancing lesion in her scalp and in T11-L5 level. The patient underwent C5-7 laminectomies and total excision of the tumor under operative microscope, and intraoperative ultrasonography and physiological monitoring were used during the surgery. Histopathologically, her tumor was found to be a ependymoma without malignant features (grade II in the World Health Organization classification). Therefore, no adjuvant therapy was applied. Following the operation, the patient showed an uneventful clinical recovery with no evidence of tumor recurrence after one year of follow-up.
