Abstract

Methods for treating maladies such as cutaneous vascular lesions. A patient in need of vascular lesion treatment is identified. A hyperosmotic agent is administered to a region adjacent the lesion. Blood flow velocity is slowed within the region using the hyperosmotic agent, and the lesion is exposed to laser radiation.

Claims

1. A method for reducing the amount of radiation required to destroy a blood vessel of a cutaneous vascular lesion comprising administering a hyperosmotic agent to the blood vessel to slow blood flow velocity prior to exposure to laser radiation.

2. The method of claim 1, wherein the amount of radiation is reduced by at least 15%.

3. The method of claim 1, wherein blood flow velocity is slowed by at least 15%.

4. The method of claim 1, wherein blood flow velocity is slowed to zero.

5. The method of claim 1, wherein administering comprises injection.
