Abstract

Background: Surgical treatment of peripheral vascular malformations is widely performed as primary and secondary treatments. Excellent results have been reported; however, it is thought that complications are likely to occur because of damage to adjacent structures. This systematic review aimed to elucidate the indications and outcomes of surgical treatment of vascular malformations. Methods: PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials were searched for studies reporting outcomes of surgery in at least 15 patients with a single type of peripheral soft-tissue vascular malformation. The authors extracted data on patient and lesion characteristics, treatment characteristics, and outcomes (including complications). Meta-analysis was conducted on recurrence and complication rates. Results: A total of 3042 articles were found, of which 24 were included: nine studies on arteriovenous malformations, seven on venous malformations, and eight on lymphatic malformations, totaling 980 patients. Meta-analyses showed pooled proportions for recurrences of 11 percent in arteriovenous malformations, 5 percent in venous malformations, and 9 percent in lymphatic malformations. Pooled proportions of major complications were 9 percent for arteriovenous malformations, 3 percent for venous malformations, and 1 percent for lymphatic malformations. The authors found a 5 percent pooled recurrence proportion in total resections, compared with 28 percent in subtotal resections. The pooled odds ratio for recurrence in total and subtotal resections showed a significant lower recurrence rate after total resection (odds ratio, 0.14, p = 0.02). Conclusions: Surgical treatment of vascular malformations appears to be effective and safe in many cases. However, it seems that surgery is performed predominantly in small lesions, and subtotal resection has a higher risk of recurrence than total resection.
