Randomized Controlled Trial Multicenter Study Comparative Study
Tumescent anaesthesia in combination with femoral nerve block for surgery of varicose veins: prilocaine 0.1% versus 0.2%.
Results of a prospective, randomized, double-blinded study about tumescent anaesthesia (TA) in combination with femoral nerve block (FNB) for surgery of varicose veins are reported. The aim is to compare two different concentrations of prilocaine in TA. ⋯ TA with prilocaine 0.1% in combination with FNB is sufficient to provide high patient satisfaction during varicosis surgery.

Visual disturbances (VDs) are reported with an average rate of 1.4% after foam sclerotherapy (FS). Some clinical clues indicate that they could correspond to migraine with aura (MA). ⋯ These results show that VDs occurring after FS correspond to MA and are not transient ischaemic cerebro-vascular events. We suggest a pathophysiological hypothesis resting on the release of endothelin that would reach the cerebral cortex through a paten foramen ovale.
