FAVA is a complex vascular malformation in the spectrum of low-flow malformations that typically presents with focal pain, discomfort, contractures, and
phlebectasia. Imaging characteristics include a fibrofatty lesion overlying a VM usually located in the calf or forearm (3).
The term
Phlebectasia indicates dilatation of a vein without tortuosity anywhere in the body.
Furthermore, it has been stated that IJV duplication is frequently recorded to be associated with
phlebectasia, which suggests abnormalities in the development of the venous wall, perhaps involving incomplete development of the muscular layer (Som et al., 1985; Rossi & Tortori-Donati; Turan-Ozdemir et al., 2004; Snoj & Cvetko).
Phlebectasia is an abnormal fusiform dilation of a vein.
The differential diagnosis of such swellings includes a laryngocele, goiter, a cystic hygroma, a large Zenker's diverticulum, and
phlebectasia of the internal jugular vein.
However, it mainly suffers from injection pain,12 as an inevitable issue of which even adults are afraid.13 With elusive mechanisms, the injection pain of propofol has mainly been attributed to the pain-inducing effect originating from the contact between aqueous phase of emulsion and free nerve endings14 or the delaying effect based on bradykinin produced by the activated kinin cascade system.15 Bradykinin leads to local
phlebectasia and increases vascular wall permeability, so propofol can penetrate the vascular wall to contact with more free nerve endings, thus aggravating the injection pain.16

Vascular lesions of the gastrointestinal tract include hemangioma, telangiectasia, angiodysplasia and
phlebectasia (1) and they account for 5-10% of all benign neoplasms of the small bowel.
The differential diagnosis of cystic swelling in the upper part of the neck should include TDC, branchial cyst, submandibular salivary gland duct cyst, cystic hygroma, saccular cyst, mucous retention cyst, laryngocele and jugular vein
phlebectasia, and pharyngocele.
Benign results, such as
phlebectasia and lymphangiectasia, were commonly found in more than 65% of the video capsule endoscopies but were not included in the analysis.
