An Eyebrow, Supracarotid Triangle Approach for Lesions at the Ventral Thalamopeduncular Junction: A Technical Report.

BACKGROUND: Lesions arising at the ventral thalamopeduncular junction are difficult to resect. In addition to being relatively inaccessible, these lesions are located in one of the most sensitive areas of the brain. A critical question is whether new approaches could be developed to allow surgeons to adequately resect these lesions with reasonable outcomes. In the present report, we describe our approach to resect lesions in this region of the brain using an eyebrow craniotomy approach with a trajectory through the supracarotid triangle. METHODS: Through retrospective data collection, we present a small series of patients who had undergone an eyebrow, supracarotid triangle approach to resect lesions located at the thalamopeduncular junction. We describe our surgical technique and report patient outcomes using this approach. RESULTS: Three patients had undergone an eyebrow, supracarotid approach for resection of a lesion arising at the ventral thalamopeduncular junction. Two patients had presented with a cavernoma and one with a pilocytic astrocytoma. Complete resection of all 3 lesions was achieved during surgery without any intraoperative complications. No patient developed permanent contralateral weakness despite entering the peduncle during surgery. One patient developed permanent paresthesia in his left hand. CONCLUSIONS: Lesions arising at the ventral thalamopeduncular junction can be adequately resected with reasonable outcomes using an eyebrow, supracarotid triangle approach. This operative technique establishes another potential operative corridor by which neurosurgeons can resect lesions arising within this relatively inaccessible part of the brain.

Access to spine care: a tale of two cities.

INTRODUCTION: As governments struggle with increasing demand for accountability within the Canadian Health Care System and set wait-time standards, it is important to objectify data to allow a true understanding of present limitations and to facilitate comparisons to other systems. The purpose of this study was to compare wait list times for a cohort of patients requiring spinal surgery in Calgary, Alberta to a similar cohort in Sydney, Australia. METHODS: From January 1 until June 30, 2006 all outpatients admitted for spinal surgery to the Foothills Hospital were identified by the surgeons' office. Two time periods were quantified from their charts: (1) time from referral to surgical consultation; and (2) time from surgical consultation to operative intervention. From July 1 until December 31,2006 patients were similarly identified through Neurosurgical offices at the Prince of Wales Public and Private Hospitals in Sydney, Australia. RESULTS: Four hundred ninety-one surgical patients were captured during the six month period in Calgary and 155 patients during the subsequent six months in Sydney. The majority of patients in Sydney were treated in the Private Health Care system. Public patients in Sydney have access to a surgical consultant twice as fast as public patients in Calgary while private patients have access ten times faster. Access to operating room time within the public system is a rate limiting step in both countries. However, Sydney private patients receive their surgery four times faster than Calgary patients. CONCLUSIONS: Compared to Calgary, access to specialized spine care in Sydney appears more efficient not only in the Private but also the Public Health Care System. Part of this efficiency may arise from offloading from the public into the private system. Solutions proposed to reduce wait list times should consider benefits of a Private Health Care System.
