This document provides tips for using a PowerPoint presentation on vascular anomalies: 1. The presentation can be freely downloaded, edited, and modified. It includes blank slides for discussion of each topic. 2. The presenter should show blank slides on each topic, ask students what they know, and then show the slide with information. 3. This active learning technique should be repeated for revisions to reinforce learning. The presentation is also useful for self-study with notes providing sources.

- 1. Tips on using my ppt. 1. You can freely download, edit, modify and put your name etc. 2. Don’t be concerned about number of slides. Half the slides are blanks except for the title. 3. First show the blank slides (eg. Aetiology ) > Ask students what they already know about ethology of today's topic. > Then show next slide which enumerates aetiologies. 4. At the end rerun the show – show blank> ask questions > show next slide. 5. This will be an ACTIVE LEARNING SESSION x three revisions. 6. Good for self study also. 7. See notes for bibliography.
- 3. Vascular anomalies • Abnormal swellings made up of blood vessels.
- 4. Vascular anomalies: Classification Two- • Hemangioma • Vascular Malformations 1.High Flow -AV fistula 2.Low flow – capillary malformation - port-wine stains – venous malformations Cavernous hemangioma. – Lymphatic malformations
- 5. Hemangioma • Vascular tumor-like structure • Present at or around birth or appeared later in life. • Self-involuting • Growing faster than body of patient • Eventually disappear
- 6. Vascular Malformations • Enlarged or abnormal vessels • present at birth • Grow with rest of the body of patient • Essentially permanent.
- 7. Etiology
- 8. Etiology • Congenital – Mostly sporadic – Rarely autosomal dominant • Traumatic • Infections /Infestation • Autoimmunity • Neoplastic (Benign/Malignant) • Degenerative
- 9. Etiology • Congenital – Mostly sporadic – Rarely autosomal dominant • Traumatic • Infections /Infestation • Autoimmunity • Neoplastic (Benign/Malignant) • Degenerative
- 11. Clinical Features • Demography • Symptoms • Signs • Complications
- 12. Demography
- 13. Demography • Common in whites 10% of live births
- 14. Symptoms:
- 15. Symptoms: site • Head and neck (59%) • Trunk (24%) • Lower extremities (10%) • Upper extremities (7%) • Liver and other viscra
- 16. Symptoms: Appearance • Colored congenital lesion • Vary from a hypopigmented macule to a bruiselike macule. • Lymphangioma-Soft doughy masses that are located in the head and neck region,
- 17. Symptoms:Natural history • Proliferative postnatal growth phase that lasts for 3-9 months • Gradual involution that occurs over 2-6 years. • Involution is usually complete by age 7-10 years.
- 18. Symptoms:Complications • In some cases, hemangiomas can be life- threatening or severely problematic, interfering with eating, breathing, seeing, hearing, and speaking.
- 19. Diagnostic Studies • MRI • USG
- 20. Management
- 21. Management • Watchful waiting • Capillary malformations - argon laser or a flashlamp-pumped pulsed dye laser (PDL). • Lymphangiomas -surgical excision • Systemic glucocorticoids • Beta blocker propranolol • Triamcinolone • Interferon alfa-2a • Ethanol sclerotherapy for venous malformation
- 23. Associated syndromes • Klippel-Trenaunay-Weber syndrome • Sturge-Weber syndrome
- 24. Klippel-Trenaunay-Weber syndrome • Triad – Vascular tumors of the limbs, trunk, or perineum; – Varicose veins – Hypertrophy of the extremities
- 25. Sturge-Weber syndrome • Facial lesion • Epileptic seizures • Hemiplegia • Visual field defects • Glaucoma.

- The terminology used to define, describe and categorize vascular anomalies, abnormal lumps made up of blood vessels, has changed. The term hemangioma originally described any vascular tumor-like structure, whether it was present at or around birth or appeared later in life. Mulliken et al. categorized these conditions into two families: one of self-involuting tumors, growing lesions that eventually disappear, and another of malformations, enlarged or abnormal vessels present at birth and essentially permanent. The importance of this distinction is that it makes it possible for early-in-life differentiation between lesions that will resolve versus those that are permanent. Examples of permanent malformations include port-wine stains (capillary vascular malformation) and masses of abnormal swollen veins(venous malformations).[3] The Mulliken categorisation has received major confirmation following discovery of the Glut-1 marker.[citation needed]

- Vascular malformations - These are subdivided into high-flow (arterial, arteriovenous) malformations and slow-flow (venous, capillary, lymphatic) malformations;
