“…First, there are many other factors that must be considered in addition to the severity of ICA lesions when determining the prognosis of MMD patients. The prognosis of MMD patients with ischemic stroke is considerably impacted by the compensatory capacity of collateral circulation [9]. The ischemic area is maintained by collateral or new vessels when severe ICA stenosis or occlusion occurs, preventing insufficient blood flow and minimizing brain tissue damage.…”

It is essential to assess the condition of moyamoya disease (MMD) patients accurately and promptly to prevent MMD from endangering their lives. A Pseudo-Three-Dimensional Residual Network (P3D ResNet) was proposed to process spatial and temporal information, which was implemented in the identification of MMD stages. Digital Subtraction Angiography (DSA) sequences were split into mild, moderate and severe stages in accordance with the progression of MMD, and divided into a training set, a verification set, and a test set with a ratio of 6:2:2 after data enhancement. The features of the DSA images were processed using decoupled three-dimensional (3D) convolution. To increase the receptive field and preserve the features of the vessels, decoupled 3D dilated convolutions that are equivalent to two-dimensional dilated convolutions, plus one-dimensional dilated convolution, were utilized in the spatial and temporal domains, respectively. Then, they were coupled in serial, parallel, and serial–parallel modes to form P3D modules based on the structure of the residual unit. The three kinds of module were placed in a proper sequence to create the complete P3D ResNet. The experimental results demonstrate that the accuracy of P3D ResNet can reach 95.78% with appropriate parameter quantities, making it easy to implement in a clinical setting.

In order to evaluate short-term effects of extra-intracranial arterial bypass procedure (EIAB) on cerebral function, we performed neurophysiological studies, combined with CT-evaluation, on 17 patients undergoing EIAB, pre- and postoperatively. CT helps to define, on a morphological basis, the extent of ischemic brain damage, and is, in some cases, a valuable tool in preoperatively assessing chances for a recovery. EEG shows, 2 weeks after surgery, in 50% of the patients after completed stroke, worsening of ischemic lesions as a result of reduced intraoperative cerebral perfusion and/or temporary occlusion of the recipient cortical vessel.
