SIR: Leaky Vein Valves Time to Menstrual Cycle

CHICAGO -- Where a woman is in her menstrual cycle may affect varicose vein diagnosis, according to a small exploratory study.

Women complaining of classic symptoms of varicose veins but no abnormalities in the long saphenous vein presented a very different picture when they returned right before their menstrual period or when symptomatic, Praveen Anchala, MD, and Scott A. Resnick, MD, both of Northwestern University in Chicago, found.

In a study of five such women, four had significant saphenous vein insufficiency on subsequent evaluation, they reported here at the Society of Interventional Radiology meeting.

Long saphenous vein diameter rose 73% on average between the evaluations.

"When evaluating menorrheal patients with history indicating likely insufficiency but no objective findings on initial evaluation, it may be beneficial to reevaluate these patients in the immediate premenstrual period," Anchala told attendees at the session.

John A. Kaufman, MD, of the Oregon Health & Science University Hospital in Portland, agreed.

"This is a very interesting observation in a small number of patients that could have significant consequences with respect to the diagnosis and management of venous reflux in menstruating women," he told MedPage Today in an email.
