Event Description
|
This complaint is from a literature source.As reported in the literature publication entitled ¿optimal guiding catheter length for endovascular coiling of intracranial aneurysms in anterior circulation in era of flourishing distal access system¿.1 patient with anterior circulation aneurysms who underwent aneurysms embolization with guiding catheter envoy experienced significant focal spasm caused by the tip of the envoy catheter.The catheter system needed to be switched from the conventional envoy to the envoy da xb.Purpose: to determine the minimum required guiding catheter length for embolization of various intracranial aneurysms in anterior circulation and to analyze the effect of various patient factors on the required catheter length and potential interaction with its stability.Materials and methods: from december 2016 to march 2017, 90 patients with 93 anterior circulation aneurysms were enrolled.Three types of guiding catheters (envoy, envoy da, and envoy da xb; codman neurovascular, raynham, ma, usa) were used.We measured the in-the-body length of the catheter and checked the catheter tip location in the carotid artery.We analyzed factors affecting the in-the-body length and stability of the guiding catheter system.
