Imaging of Venous Insufficiency

Imaging of Lower Extremity Venous Insufficiency

Varicose veins are common in Western populations, affecting an estimated 22–29% of the population. About 5% of these people have venous edema, skin changes, or venous ulcers. Varicosities are more commonly found in women, and the Framingham study showed that 10% of women younger than 30 years and 77% of women older than 70 years have varicose veins. Risk factors include family history, advancin...

Chronic Cerebrospinal Venous Insufficiency

I read with interest the article published by Kugler et al. [1]. Regarding the duplex ultrasound examination the author didn't consider the paper by Zamboni et al. [2] published in December 2011 on international angiology. In this document the authors noted that a high prevalence ranging from 62% to 100% of obstructive lesions has been found by some teams in patients with multiple sclerosis (MS...

Edema in venous insufficiency

Edema is a clinical state characterized by an accumulation of fluid in the interstitial or intracellular space. This accumulation develops when the net transcapillary filtration rate exceeds the lymphatic drainage rate over a period of time. In other words, increased filtration or reduced lymph flow or both. The present chapter focuses on the lower limb edema frequently associated with venous i...

Chronic cerebrospinal venous insufficiency.

The initial peer-review publications by Zamboni and colleagues described cerebral venous circulatory patterns in patients with multiple sclerosis (MS) that were distinct from those observed in a population without neurologic disease and concluded that interventions to modify these could provide a potential therapy for the disease development and/or its associated symptoms. These publications co...
