PORT WINE STAIN PRESENTATION
Port wine stains (capillary vascular malformations) of the face are the hallmark of the Sturge-Weber syndrome. WOUNDS IN PORT WINE STAINS
• Port wine stains are comprised of a massive excess of capillaries. Therefore, wounds in port wine stains tend • Compression bandages are important before and after suturing wounds in port wine stains.

• Deeper wounds require dermal suturing to obtain perfect dermal alignment. Resorbable 4.0 sutures should • Cutanous sutures should be non resorbable, 4.0 or 5.0 and removed in 7-10 days.
• Patients should wear a compressive bandage for 24 hours following suturing.
• Patients should be seen in follow up the next day.
NEUROLOGIC PRESENTATIONS

• They have a very friable surface and bleed frequently.
• Seizures develop in 70 to 80% of the patients.
• Local anesthesia is the same as for any skin injury.
• The risk of developing seizures is highest in the first two years.

• Many patients have frequent and repeated seizures but some children have only occasional seizures.
OTHER DERMATOLOGIC CONDITIONS OF THE SKIN INVOLVED WITH A PORT WINE STAIN
• EEG studies document decreased amplitude and frequency of electrocerebral activity over the affected hemisphere. Diffuse, multiple and independent spike foci are commonly present.

Immediate management includes assessment Health Sciences Center, Dept. of Dermatology, Denver, CO of vital functions, establishment of intravenous lines, blood sampling for investigation of possible metabolic or infectious causes and IV benzodiazepines such as lorazepam. IV benzodiazepines may John Bodensteiner, M.D., Pediatric Neurology, St. Joseph’s Children’s Health Center, Phoenix, AZ be repeated if necessary. If seizures are not controlled within minutes of giving benzodiazepines, IV fosphenytoin or phenobarbital should be given in adequate doses.
