The prevalence of diabetes and obesity is continuously increasing worldwide. The mechanisms between diabetes, obesity and their associated mortality and co-morbidities need to be further investigated. Here, we present a protocol for sleeve gastrectomy (SG) in animals as an uncomplicated preclinical model of bariatric surgery.

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,...
FAQs
The aneurysm neck forms the connection between the weakened vessel wall and the normal circulation. Closing this region prevents blood from continuing to enter the aneurysm while avoiding unnecessary interference with the parent vessel and nearby arteries. This anatomical targeting is central to separating the abnormal structure from circulation without compromising the surrounding vascular network.
Successful treatment requires more than excluding the aneurysm. Flow must also continue through adjacent arteries that supply surrounding brain tissue. A clip positioned to isolate the abnormal sac while preserving those vessels supports normal circulation and reduces the risk that treatment of one vascular abnormality will disrupt neighboring parts of the cerebrovascular system.
Surgical clipping may be considered for both ruptured and unruptured intracranial aneurysms, but the clinical context differs. A ruptured aneurysm has already caused bleeding, whereas an unruptured aneurysm has not. In either setting, the decision depends on the aneurysm’s size, location, and anatomy, together with the goal of preventing further harm.
Size, location, and anatomy are key features in deciding whether surgical clipping is appropriate. These characteristics influence how the aneurysm relates to the normal vessel network and whether a clip can isolate it while maintaining nearby arterial flow. Clinical decision-making therefore connects the lesion’s physical structure with the intended protective outcome.
Surgical clipping brings together microsurgery and imaging rather than relying on a single biological principle. Microsurgical handling allows the surgeon to address the aneurysm and its neck, while imaging contributes to understanding the abnormal vessel and its relationship to surrounding arteries. Together, these disciplines support anatomical planning and evaluation of circulation-preserving treatment.
By excluding an aneurysm from normal circulation, clipping may prevent the weakened vessel from continuing to enlarge, rupturing, or causing recurrent bleeding. The expected benefit depends on the aneurysm’s characteristics and clinical setting, so the procedure belongs within broader management of cerebrovascular disease rather than serving as an identical intervention for every patient.
