Objective To evaluate the treatment of spinal cord vascular malformations by endo vascular therapy. Methods All 41 patients including 3 cases were embolized by 3 0 silk line segments, 14 cases by selective embolization of dry dura particles, 16 by PVA and 8 cases by NBCA. Results Lesions were completely embolized in 27 cases, and partialy embolized in 14 cases. Paralysis of limbs were significantly improved in 36 cases, the other 5 cases showed no improvement on account of previous resection of the lesions. During 32 months follow up period, 18 cases recovered completely but with recurrence in 5. Conclusion Endovascular therapy is effective for spinal cord vascular malformations.

Objective To evaluate the efficacy of embolization for spinal intramedullary arteriovenous malformations.Methods 25 patients with spinal intramedullary arteriovenous malformations (AVMs) were reviewed. Embolic therapy was conducted in 4 patients by introducing the tip of a catheter into the segmental arteries and injecting lyophilized dura or polyvinyl alcohol(PVA). Microcatheter were navigated into the feeding arteries and injected PVA in 9 patients, and NBCA in 7 patients. Embosphere was used after embolizing an aneurysm in the feeding artery with NBCA in one pateint. Results Spinal angiography immediately after embolization disclosed that the lesion were obliterated almost entirely in 12 cases and partially in others. The anterior or posterior spinal artery was preserved in all patients recently. The clinical follow-up period after embolization ranged from 6 to 60 months. 16 patients improved but four patients did not show any improvement.Conclusions Embolization appears to be the treatment of first choice in the management of juvenile or partial glomus AVMs which are not amenable to surgery.

Objective:To explore the effectiveness of autologous fat grafting in the treatment of undesirable skin expansion.Methods:Patients' data were reviewed from 2011 to 2016, including the expanded regions with early signs of skin complications in face and neck. The effects of fat grafting group and control group were evaluated by follow-up records of expansion volume, skin thickness, skin texture and local capillary reaction.Results:Fat grafting could increase the thickness of expanded skin. It also improved the texture of expanded skin, with 0.83± 0.71 points before treatment and 1.30±0.66 points after treatment ( P=0.04). The local capillary reaction was also improved from 1.06±0.54 points before treatment and 1.45±0.51 points after treatment ( P=0.03). The expansion in the fat grafting group was 2.21±0.57 times before treatment and 2.94±0.83 times after treatment. In the control group, the expansion was 2.19 times when it showed early signs, and no obvious changes were observed during the follow-up period. Conclusions:Autologous fat grafting can effectively treat complications of skin expansion, prolong expansion process and promote tissue regeneration.
