Treatment of XXXX : feasibility of endovascular trapping or proximal obliteration of the ICA.

@entity1 @entity16 @entity439 @entity1756
OBJECTIVE: @entity1756 arising from non-branching sites of the internal carotid artery (ICA) are often difficult to treat by neck clipping or endosaccular coiling. We discuss the feasibility of simple endovascular ICA ligation or trapping to treat @entity439 . METHODS: Data from eleven @entity1 were retrospectively analyzed regarding Hunt and Hess grade on admission, angiographic collateral capacities during digital carotid compression, results of balloon test occlusion of the ipsilateral ICA, type of treatment, and Glasgow outcome scale at discharge. RESULTS: First endovascular treatments were performed by day 5 in four cases. Two @entity1 with good clinical grade and good collateral capacity underwent endovascular ICA trapping in the acute stage and showed good outcomes. Two @entity1 displaying poor clinical grade but good collaterals underwent endosaccular embolization. These @entity439 recurred later and the ICAs were trapped by coils in the chronic stage. Four cases underwent first endovascular treatments in the chronic stage. Three @entity1 with good collaterals underwent endovascular ICA trapping or ligation and showed favorable outcomes. CONCLUSIONS: Seven of eleven @entity1 could be treated by endovascular ICA trapping or ligation, which offers a simple, safe method for @entity1756 , if collateral capacity is good and @entity16 is not serious.
