CT findings in splenic hemangiomas in the Klippel-Trenaunay-Weber syndrome.

The Klippel-Trenaunay-Weber syndrome consists of cutaneous port wine hemangiomas, superficial venous varicosities, and soft tissue and bony hypertrophy of an extremity. We describe three patients with this syndrome with hypodense lesions in the spleen which in one case became isodense after bolus contrast CT. In one case ultrasound found numerous echopenic and echogenic masses.

Peripheral vascular perfusion scanning. Correlation with the arteriogram and clinical assessment in the patient with peripheral vascular disease.

Peripheral vascular perfusion scan during rest and reactive hyperemia does not necessarily offer the same information as the arteriogram or the clinical assessment of the peripheral pulses. The information obtained from the peripheral vascular perfusion scan offers potentially clinically useful information regarding the physiologic significance of various arterial lesions to the surgeon in selection of his therapeutic approach. The peripheral vascular perfusion scan uniquely and under varied physiologic conditions permits assessment of the effect of arterial disease on the distribution of perfusion within the extremity.

A useful, objective criterion for determining the healing potential of an ischemic ulcer.

Peripheral vascular perfusion studies utilizing intra-arterial injections of radioactive microspheres were performed on 60 patients who had ischemic ulcers of the lower extremity. Point counting over the lesion and adjacent areas was utilized to qualitate and quantitate the relative hyperemia of the lesion. When this this relative hyperemia ulcers healed.
