A 33-year-old woman with a segmental non-involuting congenital vascular anomaly of the left neck developed pain and ulceration in pregnancy and left-sided Horner's syndrome after delivery. Mutational analysis of affected tissue showed a missense mutation in GNA11 (Glu209) and a second mutation in PIK3CA. Sirolimus therapy resulted in healing of the ulceration and resolution of the Horner's syndrome.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
