The role of intraoperative magnetic resonance imaging for the detection of hemorrhagic complications during surgery for intracerebral lesions an experimental approach

Fibrinolysis therapy achieved with tissue plasminogen activator and aspiration of the liquefied clot after experimental intracerebral hemorrhage: rapid reduction in hematoma volume but intensification of delayed edema formation

“…The volume of hematoma was calculated on T 2 -weighted GE images and the edema volume on T 2 -weighted FLAIR images. 57 The areas of hemorrhage and edema were traced directly on the MR imaging screen for each slice. The total volumes of hematoma and edema were calculated by multiplying the 3-mm slice thickness by the measured areas; the calculation was performed using MR imaging software.…”

Predicting Cerebral Hyperperfusion Syndrome Following Superficial Temporal Artery to Middle Cerebral Artery Bypass based on Intraoperative Perfusion-Weighted Magnetic Resonance Imaging

“…However, it is rarely reported to be used in the neurovascular surgery. It was proven to be helpful in preventing insidious or early complications during operation, such as cerebral ischemia and hemorrhage 24 . It may be too early to comment upon the clinical superiority of iMRI over postoperative MRI in the detection of cerebral hyperperfusion after considering the high-cost iMRI.…”

Evacuation of intracerebral hemorrhages by neuroendoscopy with transparent sheath. Experimental study

“…Hematoma volumes so large are advantageous in our model, because the diameter of the largest instrument (outer sheath) is 10 mm and, therefore, larger hematomas are required to assess efficacy of endoscopic evacuation. In previous experimental models, cranial burr hole was located taking as references coronal [14,16,18,19,[21][22][23][24] and sagittal sutures [14,16,18,19,[21][22][23][24]. In our model, locating both sutures was not necessary and selected references were very easy: 15 mm lateral to midline and in projection line of lateral eye epicanthus.…”
