ReviewTo clip or to coil acutely ruptured intracranial aneurysms: update on the debate.
The purpose of this review is to consider why the International Subarachnoid Aneurysm Trial (ISAT) led to such an uproar, provide a summary of the criticisms of the study and responses from the investigators, and discuss the implications of ISAT. ⋯ The study was well designed and executed. The published results met the most up-to-date standards for reporting clinical trials. Important questions remain to be answered, including how to define clinical equipoise and the long-term durability of coiling aneurysms.

Small-for-size syndrome (SFSS) is a clinical syndrome described following liver transplantation (LT) and extended hepatectomy. New evidence has emerged documenting the importance of preoperative evaluation of functional liver mass, liver quality, influence of portal hypertension, and variations in surgical technique to improve outcome. ⋯ Current radiologic imaging techniques can be used to evaluate liver volume and the risk of SFSS following LT and extended hepatectomy. Intraoperative techniques to predict postoperative dysfunction are emerging, and may be helpful in directing the use of pre-emptive surgical interventions. The future lies in the development of perioperative liver protection and support in predicted SFSS, and enhancement of healthy liver regeneration.
