一名患有中肠卷发症的青少年中肠静脉形病例报告

We present a detailed protocol to generate a murine xenograft model of venous malformation. This model is based on the subcutaneous injection of patient-derived endothelial cells containing hyper-activating TIE2 and/or PIK3CA gene mutations. Xenograft lesions closely recapitulate the histopathological features of VM patient...

Source: Rennert, R. C., et al. Comprehensive Endovascular and Open Surgical Management of Cerebral Arteriovenous Malformations. J. Vis. Exp. (2017).This video demonstrates the open surgical resection of a cerebral arteriovenous malformation (AVM) in a human brain. The procedure involves creating a bone flap, accessing the subarachnoid space, identifying and occluding feeding arteries and draining veins, and carefully removing the AVM. Intraoperative angiography confirms complete resection,...

The mosquito midgut and salivary glands are key entry and exit points for vector pathogens like Plasmodium falciparum and the dengue virus. This video demonstrates the dissection techniques for removing the midgut and salivary glands from Aedes aegypti...

This article presents a multimodal approach that aims to overcome the limitations of traditional methods in detecting mesenteric ischemia and preventing bowel necrosis. The presented technique offers a promising solution by combining state-of-the-art ultrasonography with cutting-edge near-infrared light...

Surgery is the gold standard for accessible arteriovenious malformations (AVMs), and pre-operative embolization can simplify this procedure. We describe our approach for staged endovascular embolization and open resection of AVMs, and provide a representative clinical example highlighting the advantages of a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical...

In this video, we highlight a dissection of the adult Drosophila intestine and collection of midguts suitable for single-cell dissociation and FACS in order to isolate intestinal stem...
