hemangioendothelioma
angiosarcoma
Misc

3

What is the sub-classification of vascular malformations?

Slow-flow
capillary malformation CM
lymphatic malfomation LM
venous malformation VM

Fast flow
arterial malformation

Combined

4

What is the most common location for infantile hemangiomas?

head and neck

5

Describe what slow flow CM are and treatment.

Red macular lesions seen at birth and persist throughout life
Laser tx for cosmesis

6

Names three diseases associated with SF CM.

sturge weber
cutis marmorata telangiectatica congenita
Macrocephaly-CM

7

Describe what SF VM look like and treatment.

Bluish compressible swellings
Can be painful
Can be extensive and lead to leg length discrepancy
At risk for systemic coagulopathy after trauma
Tx OR can have significant blood loss
tourniquet

8

Names three diseases associated with SF VM.

Glomuvenous malformation
Cutaneomucosal venous malformation
Blue rubber bleb nevus syndrome

9

Describe what SF LM are and treatment.

Microcystic cmor combined
Tx lenticular excision
Dissect off skin, not malignant need not excise everything
May need to remove associated viscera
Post op, suction drainage

10

Name types of fast flow VM.

AVF
AVM

11

What are symptoms of AVF?

LE—edema, hypertrophy, trophic changes
UE—pain, digital ischemia, discoloration of the digits

12

What is an AVM?

Center call nidus has feeding vessels, micro and macro AVFS and ecstatic veins

13

Where are AVM most commonly found?

Intracranial, followed by limbs, trunk and viscera

14

How do you stage AVM?

I quiescence
Cutaneous blush, warmth (av shuntung on Doppler)
Stage II expansion
Bruit, audible pulsation, expanding lesion
Stage II destruction
Pain ulceration, bleeding, infection
Stage IV decompensation
Cardiac failure

15

What are indications to treat AVM?

pain ulceration, functional impairement, soft tissue and bony destruction and bleeding.
CHF

16

What is treatment for AVM?

Embolization alone or in combo
Embo nidus then resection next few days

17

What are variation of combine VM?

fast or slow
any combo of C, L, V, A

18

What is klippel-trenaunay syndrome?

slow flow Capillary-lymphaticovenous malformation
Large and small CM extremities and buttock
Lymphedema and LM in LE
Limb hypertrophy present at birth

19

What are side effects of KTS?

Infections, PE, thrombophleb, GI, constipation, bladder outlet obstruction , hematuria

20

What is parks weber?

Fast flow capillary arteriovenous malformation CAVM or CLAV<
Usually LE and trunk
Cutaneous flushing wih underlying multiple micro AVFS

large, flat, pink stains on the skin, and because of their color are sometimes called "port-wine stains

21

What is most common tumour of infancy?

infantil hemangioma

22

What is infantile hemangioma?

benign tumor of the endothelium
most common neoplasm of infancy
gros rapidly in first year then growth plateaus then shrinkage
bright color fades becomes less tense.
last phase complete by 4 yo

23

What is most common site of infantile hemangioma?

liver
can cause hepatomeg, IVE compression

24

How to diagnose infantile hemangioma?

US or MRI

25

What is treatment of infantile hemangioma?

conservation
topical steroid
laser
embolic only for CHF
excision only if at risk for injury and blood loss
