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 team.

Histological and biochemical modifications after aneurysm endograft exclusion are still unclear. We describe a new model of endograft implantation on a murine aneurysm. Through thrombus analysis with and without persistant circulating blood stream interface, and new endovascular biomaterials evaluation, this model will help to better understand endovascular aneurysm exclusion pathobiology.

Combination of High Ligation and Intraoperative Embolization Using Polidocanol for Treatment of Varicoceles

To reduce the postoperative recurrence rate of varicocelectomy, we combined high ligation of varicocele with intraoperative embolization. We injected polidocanol from the spermatic vein during surgery to embolize the branches of the spermatic vein and collateral veins. This is an alternative surgical method for the treatment of varicocele.

FAQs
Embolic materials provide the immediate means of creating a controlled blockage at the intended site. Coils, particles, and liquid agents can lodge within a target vessel or vascular lesion, where they promote occlusion or clot formation. Their different material forms allow the procedure to deliver an embolic agent directly to the selected target, with the shared goal of reducing blood flow through it.
Targeted occlusion matters because neurological vascular lesions can pose harm through abnormal or excessive blood flow. In cerebral aneurysms, reducing flow can lower the risk of rupture. For arteriovenous malformations, limiting flow addresses the lesion’s vascular supply. The same principle can also support control of bleeding or reduction of tumor vascularity in relevant cases.
Clinicians reach the selected vessel or vascular lesion through the vasculature with a catheter rather than requiring direct access to the affected area. This minimally invasive route can lessen surgical trauma while retaining the ability to deliver embolic material precisely. That combination is particularly relevant when cerebrovascular disease is complex and a less traumatic management option is desirable.
Clinicians guide a catheter through the vasculature toward the selected vessel or vascular lesion. They then release an embolic material at the target, choosing among coils, particles, or liquid agents described for this technique. The material lodges there and promotes occlusion or clot formation, producing the intended reduction or blockage of blood flow.
In neuroscience, the approach is used for several distinct vascular problems. It can reduce rupture risk from cerebral aneurysms, limit blood flow to arteriovenous malformations, control bleeding, and reduce tumor vascularity. These applications involve different clinical goals, but each uses delivery of an embolic material to alter blood flow at a carefully selected neurological target.
Endovascular embolization can provide an important management option when cerebrovascular disease is complex. By reaching a target through blood vessels and delivering material locally, clinicians may address aneurysm rupture risk, arteriovenous malformation flow, bleeding, or tumor vascularity while potentially lessening surgical trauma. The desired outcome depends on the lesion and the specific clinical goal.
