Objective: The aim of this study was to describe 27 patients with 32 web vessels (WVs) from our practice and provide a review of the literature regarding imaging diagnostics, clinical presentation, and treatment of WVs.
Methods: A MEDLINE search was performed using combinations of the following terms: "stroke in young adults," "web," "recurrent stroke," "diaphragm-like," "atypical fibromuscular hyperplasia," "atypical fibromuscular dysplasia," "septal fibromuscular dysplasia," "septa," "diaphragms," "pseudovalvular folds," and "carotid diaphragm." Our series was added in this review.
Results: According to location, there were 88 carotid WVs (91.66%), 7 vertebral WVs (7.3%), and 1 subclavian WV (1.04%). According to clinical presentation, the reported WVs caused stroke in 81 cases (84.38%). Treatment was supportive care in 46 cases (47.91%), surgery in 33 cases (35.41%), and an endovascular procedure through angioplasty and stenting in 17 cases (17.7%). Variables such as age (P = 0.7565), sex (P = 0.6912), and location (P = 0.7993) were not shown to be risk factors for stroke in these patients.
Conclusions: Although few cases have been reported in the literature, the stroke rate in patients with WVs is high. Endovascular treatment is presented as an effective form of treatment with no associated morbidities or recurrences of ischemic events.
