Background And Purpose

Method

Patients with L-BAVMs who underwent microsurgical resection between September 2012 and June 2016 were reviewed. All patients had undergone preoperative functional magnetic resonance imaging and diffusion tensor imaging. Both functional and angioarchitectural factors were analyzed regarding the postoperative LD. Functional factors included the eloquence involved, the side of blood-oxygenation level-dependent signal activation and the white-matter fibers (anterior segment, long segment [LS], and posterior segment of arcuate fasciculus, and the inferior fronto-occipital fasciculus) involved.

Conclusion

L-BAVMs located in Geschwind's territory can cause a high incidence of LD. LS involvement and larger nidus size are risk factors for postoperative short- and long-term LD, and preoperative LD is a risk factor for postoperative, long-term LD.

Main results

Sixty-nine patients with L-BAVMs were reviewed. Postoperative short- and long-term LD was found in 32 (46.4%) and 14 (20.3%) patients, respectively. Twelve of the 14 patients with Geschwind's territory L-BAVMs (85.7%) had short-term LD, compared with 10 (34.5%) in Wernicke's and 10 (38.5%) in Broca's area. LS involvement (P = 0.001) and larger nidus size (P = 0.017) were independent risk factors for the short-term LD. Meanwhile, nidus size (P = 0.007), preoperative LD (P = 0.008), and LS involvement (P = 0.028) were independent risk factors for long-term LD.
