RESUMO
CONCLUSION: Closure of arteriovenous fistula should be considered in patients who underwent successful renal transplantation to avoid potential complications that may result from the presence of unused fistula especially, in patients who are predisposed to aneurysm formation in the future.

Drainage of the arterial wall via adventitial lymphatic vessels has been shown to play a pivotal role for vessel wall homeostasis. Also, retrograde cholesterol transport is ensured via this route, but no studies exist to demonstrate that lymphatic stasis would represent a mechanism to initiate atherosclerotic lesion formation in human arteries. To test this hypothesis, we embarked on a simple clinical experiment, assessing wall thickness in limb arteries with lymphedema after surgical intervention, with the contralateral limb serving as control. Using ultrasound imaging, the differential thickness was assessed separately for the three arterial wall layers. The potential of disease progression by lymphostasis was addressed by depiction of longitudinal results according to the time after lymph dissection.
