The emergency DSA examination revealed an aneurysm in the anterior and anterior communication junction of the right side of the brain. There was a pseudocyst at the top of the tumor, and the top of the tumor pointed to the upper left front, which was consistent with the distribution of spider blood shown by CT. The front A1 of the left brain was visualized. It is planned to further embolize the stent assisted coil.

Surgical instruments and models used

8F MPA guide catheter; 6F Sofia distal access catheter; Headway21 microcatheter; Headway17 microcatheter; Traxcess14 microguide wire; 3.5mm×15mm Lvis stent; MicroVention coil 1 *2, 2*2, 1.5*2, 1*1.

After treatment

Traxcess14 micro-guide ribbon Headway21 stent catheter enters the right anterior cerebral artery A2-3 segment.

The Headway17 embolization catheter is pre-shaped.

Intraoperative cerebral vasospasm and poor imaging of angiographic aneurysms.

The road map shows the approximate location of the aneurysm, and the embolization catheter is in place.

The 1ml syringe embolization catheter is slowly pushed by hand for angiography, and it is confirmed that the tip is located in the aneurysm.

MicroVention 1*2 first fills the false sac on the top of the aneurysm, then half releases the 3.5mm×15mm Lvis stent to cover the neck of the aneurysm. The stent is released and 8ml of tirofiban is injected intravenously, and then continues at 6ml/h Pump in.

The distal end of the stent is not well opened. Push the stent catheter and guide wire to promote the distal opening.

Continue to complete the proximal tumor packing .

After embolization, the angiography work position is enlarged, the work position is reduced, the standard front position and the standard lateral position image.

It can be seen that the Lvis stent opened well after the operation.

After the operation, the patient was awake under general anesthesia, with normal limbs, and the speech response was the same as before the operation. The dual anti-platelet aggregation drugs were connected within 24 hours after the operation (3h before the discontinuation of tirofiban, aspirin 100mg, clopiper Gray 75 mg; aspirin 100 mg and clopidogrel 75 mg 1 hour after tirofiban is stopped).

The surgeon’s experience

1. Front traffic movementThe position of the aneurysm is relatively close to the distal end, and the shaping of the microcatheter is very important. The primary and secondary bends should be properly shaped, and if necessary, the tertiary bend should also be properly shaped.

2. During the operation, severe cerebral vasospasm was encountered, the aneurysm was not well visualized, and it was impossible to determine whether the microcatheter was embolized in the tumor cavity or the artery bearing the tumor. In order to avoid unnecessary microcatheter operations and accurately determine the artery The location of the aneurysm, after the embolization of the microcatheter is in place, microcatheter angiography is performed to confirm that it is inside the aneurysm. The microcatheter should be pushed slowly to prevent the aneurysm from rupturing.

3. After the release of the Lvis stent, it must be ensured that the distal and proximal ends are well opened to prevent secondary thrombosis.
