fibroadipose Vascular Anomaly in the upper extremity a distinct entity with characteristic clinical radiological and histopathological findings
Journal of Hand Surgery (European Volume), 2020Co-Authors: Kevin Cheung, Samantha A. Spencer, Ahmad I Alomari, Amir H Taghinia, Ravi F Sood, Alyaa Alibraheemi, Harry P W Kozakewich, Gulraiz Chaudry, Arin K Greene, John B MullikenAbstract:Purpose Fibroadipose Vascular Anomaly (FAVA) is an intramuscular Vascular malformation that has been recently described as a distinct clinical entity. The clinical, radiological, and histopathological characteristics of FAVA in the upper extremity are reviewed. Methods This was a retrospective case series of upper-extremity FAVA lesions. Results We reviewed 19 patients with FAVA of the upper limb. Pain, stiffness, swelling, and flexion contractures were the most common presentations. Except for one lesion confined to the hand, all lesions either presented with or developed a contracture within 10 years. Ten patients underwent surgical debulking. Six required tendon transfer reconstruction and 3 necessitated a free functional muscle transfer. Conclusions Fibroadipose Vascular Anomaly in the upper extremity requires an accurate diagnosis and may benefit from early referral to a multidisciplinary Vascular Anomaly center with experienced hand surgeons. Compression garments, propranolol, and sclerotherapy seem to be ineffective. Surgical resection focused on symptomatic regions with appropriate reconstruction may have benefit in salvage of limbs with compromised function. Type of study/level of evidence Therapeutic IV.

Evaluation of terminology for Vascular anomalies in current literature.
Plastic and reconstructive surgery, 2011Co-Authors: Aladdin H. Hassanein, Steven J. Fishman, John B Mulliken, Arin K GreeneAbstract:Background: A binary classification of Vascular anomalies was approved 14 years ago by the International Society for the Study of Vascular Anomalies. The purpose of this study was to determine whether the International Society for the Study of Vascular Anomalies system is being used to categorize anomalies, and whether incorrect nomenclature affects patient care. Methods: The PubMed database was searched for English language publications with the term "hemangioma" in the title/abstract during 2009. Outcome variables were (1) whether accepted nomenclature was used to describe the Vascular Anomaly and (2) whether or not patients received incorrect treatment. Predictive variables for terminological accuracy were patient age, location of the Anomaly, and the primary author's medical specialty. Results: "Hemangioma" was used incorrectly in 71.3 percent (228 of 320) of publications. Patients whose lesions were mislabeled were more likely to receive improper treatment (20.6 percent) compared with subjects whose lesions were designated using International Society for the Study of Vascular Anomalies terminology (0.0 percent) (p = 0.001). The patients were younger in articles that properly identified hemangioma (4.1 months) compared with articles that used hemangioma to describe another Anomaly (36.1 years) (p < 0.0001). Publications focused on integument/soft-tissue lesions were more accurate (57.4 percent) than those in other anatomical areas (86.3 percent) (p < 0.0001). The erroneous use of hemangioma was independent of the authors' discipline: pediatrics (60.0 percent), internal medicine (61.4 percent), surgery (68.9 percent), and obstetrics/gynecology (70.0 percent) (p = 0.68). Conclusions: Hemangioma continues to be commonly misused to describe any type of Vascular Anomaly, and terminological imprecision is prevalent among both medical and surgical fields. Inaccurate designation of the Vascular Anomaly is associated with an increased risk of erroneous management.

noninvoluting congenital hemangioma a rare cutaneous Vascular Anomaly
Plastic and Reconstructive Surgery, 2001Co-Authors: O Enjolras, Harry P W Kozakewich, John B Mulliken, Laurence M Boon, Michel Wassef, Patricia E BurrowsAbstract:The authors studied a rare, congenital, cutaneous Vascular Anomaly that grows proportionately with the child and does not regress. A total of 53 patients were compiled from three Vascular Anomaly centers. These patients' lesions were analyzed for presentation, physical findings, radiologic and histopathologic characteristics, natural history, and outcome after resection. The lesions occurred slightly more often in male patients, always appeared alone, and were located (in order of frequency) in the head/neck region, extremities, and trunk. The) were round-to-ovoid in shape, were plaque-like or bossed, occurred in variable shades of pink to purple, and had an average diameter of 5 cm, The overlying skin was frequently punctuated by coarse telangiectasia, often with central or peripheral pallor. The lesions were warm on palpation: fast-flow was fur ther documented by Doppler ultrasonography. Magnetic resonance imaging and angiographic findings were similar to those of common hemangioma of infancy, All lesions were easily excised without recurrence. Histologic examination revealed lobular collections of small, thin-walled vessels with a large, often stellate, central vessel. Interlobular areas contained predominantly dilated, often dysplastic veins: arteries were also increased in number. Small artel ies were observed "shunting" directly into lobular vessels or into abnormal extralobular veins, "Hobnailed" endothelial cells lined the small intralobular vessels. Mast cells were increased. Tests for glucose transporter-1, a recently reported reliable marker for common hemangioma of infancy, were negative in all 26 specimens examined. In conclusion, the authors think these clinicopathologic and radiologic features define a rare Vascular lesion for which the term "noninvoluting congenital hemangioma" is proposed. These lesions of intrauterine onset may be a variant of common hemangioma of infancy or another hemangiomatous entity with persistent fast-now.

the cervical aortic arch a rare Vascular Anomaly
Circulation, 2008Co-Authors: Alexander Poellinger, Alexander Lembcke, Thomas Elgeti, Sergej Filimonov, Christian N H EnzweilerAbstract:A 27-year-old woman with slight mental retardation underwent a magnetic resonance imaging scan of the head in an outpatient clinic. In that examination, the neurocranium was unremarkable, but dissection of the right common carotid artery (CC) was suspected. The patient was transferred to our hospital. A Doppler ultrasound examination and magnetic resonance angiography of the aorta and the supraaortic vessels were performed. On physical examination, palpitations in the right superior thoracic aperture were noted. Magnetic resonance angiography revealed a complex Vascular Anomaly: a retroesophageal aortic arch extending cranially to the level of the right thoracic aperture. No brachiocephalic …

double aortic arch a rare Vascular Anomaly
Journal of the American College of Cardiology, 2020Co-Authors: Muhammad Kashif Amin, Ahmad Hallak, Muhammad Khan, Rajesh NambiarAbstract:Double aortic arch (DAA) is reported in less than 1% of congenital heart disease. The development of the aorta occurs in the third week of gestation. In embryonic Vascular development, six pairs of aortic arches connect the two primitive ventral and dorsal aortae. A portion of the right fourth arch
