In the dog's saphenous vein acetylcholine inhibits the norepinephrine release caused by nerve stimulation, but not that caused by tyramine. Experiments were performed to determine whether acetylcholine affects the release of norepinephrine evoked by high K+ concentrations. We recorded changes in isometric tension of dog saphenous vein strips. Acetylcholine (5 X 10(-9) to 10(-6) g/ml) caused dos...

Sensory impairment in the cutaneous distribution of the saphenous nerve was measured in 30 patients after bilateral stripping of the long saphenous vein. The vein was stripped upwards in one leg and downwards in the other. Three months after operation a significantly greater incidence of sensory loss was found in those legs in which the vein was stripped upwards (13 out of 26) compared with tho...

Variations of the distally based sural artery flap have been used in the literature with varying success rates. This article stresses the axiality of this flap based on the sural nerve and the short saphenous vein. Forty distally based sural artery flaps were used for a variety of defects in the distal leg. In the proximal leg, the groove between the medial and lateral heads of the gastrocnemiu...

Persistent anterior knee pain, especially after surgery, can be very frustrating for the patient and the clinician. Injury to the infrapatellar branch of the saphenous nerve (IPS) is not uncommon after knee surgeries and trauma, yet the diagnosis and treatment of IPS neuralgia is not usually taught in pain training programs. In this case report, we describe the anatomy of the saphenous nerve an...

The saphenous flap is a fasciocutaneous flap generally used for knee and upper third of the leg coverage. Due to various descriptions of the saphenous flap, such as venous, sensory, and free flap, the origin and distributing characteristics of the saphenous artery are important for plastic surgeons. The aim of this cadaveric study was to evaluate the anatomical features of the saphenous flap. T...

The saphenous nerve is the longest branch of the femoral nerve and is a purely sensory nerve. It arises from the 3rd and 4th lumbar roots. As mentioned it is an exclusively sensory. It supplies the medial articulation of the knee and cutaneous sensation of the medial aspect of the knee, leg and ankle. The nerve travels in close proximity to the femoral vessels subsartorial. This hunter canal is...

BACKGROUND AND OBJECTIVE We studied the long-term efficacy of pulsed radiofrequency treatment (PRF) on the saphenous nerve in 115 patients with chronic knee pain. MATERIALS AND METHODS 115 patients with chronic knee pain were investigated in a period of 22~months retrospectively. All patients had pulsed radiofrequency to the saphenous nerve. The mean age was 59 (range, 51-67). All patients we...
