INTRODUCTION Current MRI sequences are limited in identifying brain areas at risk for high grade glioma recurrence. We employed intraoperative 3-Tesla functional MRI to assess cerebrovascular reactivity (CVR) after high-grade glioma resection and analyzed regional CVR responses in areas of tumor recurrence on clinical follow-up imaging. METHODS Five subjects with high-grade glioma that underw...

A noteworthy endpoint of general anesthesia is the loss of memory. However, a ghastly difficulty of narcosis is the anesthesia awareness, a rare condition that happens when surgical patients can review their surroundings or an occasion identified with their surgery while they are under general anesthesia. Amid general anesthesia, the amnesia is, for the most part, accomplished with general anes...

OBJECTIVE There has never been a large, randomized controlled trial to assess the impact of intraoperative imaging on the success of carotid endarterectomy (CEA). This comparison involves cost-effectiveness analysis. METHODS We constructed a decision-analytic model to compare effectiveness and costs of intraoperative ultrasound (IUS) and completion angiography as adjuncts to CEA. Data on proc...

Intraoperative neurophysiological monitoring (IONM) makes it possible to determine the status of neurological function during surgery. It guides the surgeon and minimises the risk of injury. This paper describes the different techniques available for IONM in spine surgery (somatosensory evoked potentials, motor evoked potentials, neurography, electromyography, reflexes and dermatomic evoked pot...

OBJECTIVE Design features of intraoperative probes are presented. A brief discussion of the sentinel node concept and relevant radiopharmaceuticals is given. The importance of the injection technique and the necessity of imaging in radiotracer techniques for sentinel node detection are explained. Probe calibration, procedural precautions, intraoperative techniques, and radiation dosimetry relev...

INTRODUCTION Ultrasound can visualize and update the vessel status in real time during cerebral vascular surgery. We studied the depiction of parent vessels and aneurysms with a high-resolution 3D intraoperative ultrasound imaging system during aneurysm clipping using rotational digital subtraction angiography as a reference. METHODS We analyzed 3D intraoperative ultrasound in 39 patients wit...

We retrospectively examined intraoperative blood transfusion patterns at US veteran's hospitals through description of national patterns of intraoperative blood transfusion by indication for transfusion in the elderly; assessment of temporal trends in the use of intraoperative blood transfusion; and relationship of institutional use of intraoperative blood transfusion to hospital 30-day risk-ad...

BACKGROUND The exact assessment of a tonsil carcinoma's size is often difficult because of the tumour's submucosal extension and deep infiltration. AIM The aim of the study is to assess the usefulness of intraoperative ultrasonography in tonsil cancer. MATERIAL Twenty patients with carcinoma of the tonsil were included in the study (squamous cell carcinoma keratosis - 12, squamous cell carc...

The objective of this study was to compare the intraoperative time, intraoperative blood loss and post operative pain between coblation tonsillectomy and cold tonsillectomy in the same patient. A prospective single blind control trial was carried out on 34 patients whom underwent tonsillectomy. The patients with known bleeding disorder, history of unilateral peritonsillar abscess and unilateral...
