Treatment of pediatric intracranial dissecting aneurysm with clipping and angioplasty, and next-generation sequencing analysis: A case report and literature review

Figure 1 Preoperative imaging examination. A: Subarachnoid hemorrhage caused by ruptured intracranial dissecting aneurysm (IDA); B: Computed tomography angiography shows intracranial aneurysm in the right medical council on alcohol; C and D: Pearl-and-string sign of IDAs (focal stenoses proximally and distally, which are noted by white arrows.

Figure 2 Clipping and angioplasty for intracranial dissecting aneurysms, and pathological examination. A: The aneurysm was clipped; B: The wall of the intracranial dissecting aneurysm was very thin, and a thrombus was adhered to the wall; C: The intracranial dissecting aneurysm was resected and sent for pathological examination. Pathological examination indicated irregular and malformed vascular wall structure with inflammatory infiltration.

Figure 3 Postoperative computed tomography angiography examination and follow-up. A-C: Postoperative computed tomography angiography examination indicated that the aneurysm had been resected, and the blood flow of the constructed medical council on alcohol was unobstructed; D: The 3-year follow-up showed no recurrence.
