RESUMO
Objective: To investigate the feasibility and operative effect of the one-stage microsurgery for clipping of bilateral posterior communicating artery aneurysms (BpcoAA). Methods: The clinical data of 28 patients with BpcoAA were analyzed retrospectively. All patients underwent craniotomy and microsurgical clipping of BPcoAA via unilateral pterional approach. The patients were followed up for 6 months to 3 years after microsurgery. The head 3 D-CTA of the patients and their general conditions were reexamined. The Glasgow outcome scale (COS) scores were used to assess the prognosis. Results: Circled digit oneGood preoperative 3D-CTA showed 28 cases with 56 aneurysms, the aneurysms were clipped completely in 24 cases, the contralateral aneurysms were not clipped completely in 3 cases, the aneurysm was not clipped completely on the approach side in 1 case, and none of the patients died. The aneurysms ruptured in 8 cases on the approach sides during the microsurgery. Circled digit twoAfter microsurgery, 7 cases had hydrocephalus, and 5 had vasospasm on the approach sides and 3 on the contralateral sides, 3 suffered pulmonary infection, and 2 had oculomotor nerve injury on the contralateral sides. Circled digit threeThe mean follow-up time of the patients was 1.7 years. The GOS scores: 5 points in 10 cases, 4 points in 7 cases, 3 points in 9 cases, and 2 points in 2 cases. There were no aneurysm recurrence and new aneurysm formation. The patients whose aneurysms were not clipped completely had no recurrence of bleeding. Conclusion: According to 3D-CTA examination, using unilateral pterional approach, aiming at the location of the optic chiasm and the contralateral aneurysm pointing, the one-stage microsurgery for clipping of BpcoAA is safe and feasible.
RESUMO
0.05).Conclusion The incidence of VVC is higher in pregnant women with GDM than in pregnant women with GIGT,however, GCT,and OGTT show no statistical differences between women with VVC and those without VVC.
