It was reported that the lvis jr stent was used to treat a subarachnoid hemorrhage and aneurysm at the bifurcation of the left middle cerebral artery.When the stent was introduced into the left distal brain, the 3.5 x 23mm lvis jr stent did not fully open.The stent was wrapped by thrombus and could not be removed.The doctor chose to deploy and detach the stent.After balloon dilatation, angiogram was still poor and the doctor decided to introduce a 4.0 x 30 stent.A subsequent angiography showed that the blood flow recovered.The operation was then completed.The patient's neurological signs were normal.The patient is fine.
