BACKGROUND For many years, dissecting aneurysms of the intracranial vertebral artery were believed to be quite rare. In recent years, because vascular disorders have been studied more thoroughly by three dimensional-computed tomography (3D-CT), angiographically and pathologically, these aneurysms are being reported with more frequency. METHODS Among the(More)
BACKGROUND The surgical approach to basilar bifurcation aneurysms is a complicated procedure, especially with those located high in the interpeduncular cistern. We have developed a surgical approach to these aneurysms involving only a small anterior temporal craniotomy and detachment of the zygomatic arch. METHODS The skin incision is placed 5 mm below(More)
Desmoplastic small round cell tumor (DSRCT) is a rare tumor of adolescents and young adults. Less than 100 cases per year are reported in North America. Extensive peritoneal metastases are characteristic of this disease. We performed cytoreductive surgery and hyperthermic peritoneal perfusion with chemotherapy (HIPEC) using cisplatin (CDDP) for DSRCT. A(More)
BACKGROUND Several studies have examined the impact of anesthetics on cancer recurrence. Isoflurane but not desflurane has protumoral effects. We hypothesize the use of isoflurane but not desflurane during surgery for primary GBM is an independent predictor of disease progression and mortality. METHODS 378 adult patients were included in the study. The(More)
BACKGROUND Proton therapy is a newer modality of radiotherapy during which anesthesiologists face specific challenges related to the setup and duration of treatment sessions. PURPOSE Describe our anesthesia practice for children treated in a standalone proton therapy center, and report on complications encountered during anesthesia. MATERIALS AND(More)
Extensive tumor implants secondary to sarcoma, sarcomatosis, or mesothelioma in children is rare. We conducted the first phase 1 trial of escalating doses of cisplatin during hyperthermic intraperitoneal chemotherapy (HIPEC) in children with sarcomatosis. The most devastating complication of cisplatin therapy is nephrotoxicity. Here we present the(More)
Recent advances in cancer therapy have seen increased combinations of different treatment modalities as well as novel approaches that affect anaesthetic care. Increasingly, surgery is being combined with chemotherapy and radiation therapy. Moreover, minimally invasive procedures are gaining popularity and more targeted therapies are being used. These events(More)
Bradykinin, an endogenous nonapeptide and an important mediator of inflammation, is also implicated in the initiation and maintenance of pain. Both des-Arg(8), Leu(8)-bradykinin (dALBK) and HOE-140, the prototypic bradykinin B1 and B2 receptor antagonists, respectively, have been shown to reduce pain behaviors and inflammation in animal models of persistent(More)
Cohort studies have suggested that the use of statins is associated with decreased risk of glioma formation and mortality. Here, a cohort of patients with glioblastoma multiforme (GBM) was analyzed to further investigate associations between preoperative use of statins and recurrence, and progression free and overall survival. Patients who had surgery for(More)
BACKGROUND AND PURPOSE Physicians responsible for anesthesia and/or sedation (A/S) at emerging proton radiation therapy centers (PTCs) seek information about practices at established centers. We conducted a survey of A/S practices at established PTCs to provide this information for physicians at new PTCs. METHODS AND MATERIALS A web-based survey was sent(More)
