Which condition has been shown to have ultrasound evidence of superficial venous insufficiency in 23% of patients without visible varicosities?

The condition that has been shown to have ultrasound evidence of superficial venous insufficiency in 23% of patients without visible varicosities is Corona Phlebectatica. This condition represents an anatomic change often observed in patients with chronic venous disease, which can manifest as dilated superficial veins around the ankle and lower leg region. Importantly, these veins may not always be visibly varicosed but can still demonstrate underlying venous insufficiency upon ultrasound evaluation. The statistic that 23% of patients without visible varicosities show signs of this condition highlights the importance of ultrasound as a diagnostic tool in detecting incipient venous problems that may not be apparent through physical examination alone. This makes it critical for practitioners to use ultrasound imaging to assess venous health comprehensively, especially in patients who may exhibit symptoms of venous insufficiency but lack overt signs such as varicosities.
