Open Surgical Resection of Cerebral Arteriovenous Malformations07:25

Open Surgical Resection of Cerebral Arteriovenous Malformations

366
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,...

A Patient-Derived Xenograft Model for Venous Malformation

5.7K
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...

Induction and Micro-CT Imaging of Cerebral Cavernous Malformations in Mouse Model

11.3K
This protocol demonstrates the induction of cerebral cavernous malformation disease in a mouse model and uses contrast enhanced micro computed tomography to measure lesion burden. This method enhances the value of established mouse models to study the molecular basis and potential therapies for cerebral cavernous malformation and other cerebrovascular...

Comprehensive Endovascular and Open Surgical Management of Cerebral Arteriovenous Malformations

10.2K
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...

Cre-LoxP Mediated Induction of Cerebral Cavernous Malformations in a Mouse Model

508
In this video, a genetically modified mouse pup carrying the Ccm2 gene flanked by loxP sites and Cre recombinase fused to an estrogen receptor is used to induce cerebral cavernous malformations (CCMs). The administration of 4-hydroxytamoxifen activates Cre in endothelial cells, leading to the deletion of Ccm2 and the formation of CCMs in the...

    Area of Science:

    • Neurosurgery
    • Neurology
    • Medical History

    Background:

    • Chiari I malformation (CIM) understanding and treatment have historically lagged, with limited discussion in textbooks until recent decades.
    • Early management approaches for CIM and associated syringomyelia were largely ineffective, excluding surgical intervention.

    Purpose of the Study:

    • To review the evolution of Chiari I malformation (CIM) understanding, pathophysiology, and treatment.
    • To differentiate symptomatic CIM from asymptomatic tonsillar ectopia.
    • To discuss surgical techniques, outcomes, and complications for CIM.

    Main Methods:

    • Review of historical literature and contemporary neurosurgical practices.
    • Analysis of diagnostic advancements, particularly MRI.
    • Evaluation of patient selection criteria for surgical intervention.

    Main Results:

    • Significant advancements in understanding CIM's pathophysiology and natural history over the past 40 years.
    • Confirmation of CIM's responsiveness to surgical intervention, leading to improved patient outcomes.
    • Emphasis on accurate patient selection based on symptomatology for successful surgical outcomes.

    Conclusions:

    • Modern neurosurgical approaches have transformed CIM treatment, offering improved quality of life.
    • Distinguishing symptomatic CIM from asymptomatic tonsillar ectopia is crucial for appropriate management.
    • Continued research is vital for further enhancing patient care for Chiari I malformation.
