Giant saccular aneurysm of the cervical internal carotid artery treated with aneurysmectomy and side-to-end anastomosis.

BACKGROUND

Cervical aneurysms are rare, accounting for <1% of all arterial aneurysms, including dissecting, traumatic, mycotic, atherosclerotic, and dysplastic aneurysms. Symptoms are usually caused by cerebrovascular insufficiency; local compression or rupture is rare. We present the case of a 77-year-old man with a giant saccular aneurysm of the cervical internal carotid artery (ICA), which was treated with aneurysmectomy and side-to-end anastomosis of the ICA.

CASE DESCRIPTION

The patient had experienced cervical pulsation and shoulder stiffness for 3 months. The patient had no significant medical history. An otolaryngologist performed the vascular imaging and referred the patient to our hospital for definitive management. Neurological deficits were not observed. Digital subtraction angiography showed a giant cervical aneurysm with a diameter of 25 mm within the ICA, and there was no evidence of thrombosis within the aneurysm. Aneurysmectomy and side-to-end anastomosis of the cervical ICA were performed under general anesthesia. After the procedure, the patient experienced partial hypoglossal nerve palsy but fully recovered with speech therapy. Postoperative computed tomography angiography revealed the complete aneurysm removal and patency of the ICA. The patient was discharged on postoperative day 7.

CONCLUSION

Despite several limitations, surgical aneurysmectomy and reconstruction are recommended to eliminate the mass effect and to avoid postoperative ischemic complications, even in the endovascular era.
