[Solitary neurofibroma of the lumbosacral plexus. Case report].

The article describes a case of a solitary neurofibroma of the plexus lumbosacralis causing pain and incomplete leg paresis. Complete relief was obtained by total extirpation of the tumour, a procedure which must be regarded as the method of choice. Pain and pareses in the lower extremities require differential diagnostic consideration of rare neurogenic tumours of the peripheral nervous system in the regions of the pelvis and plexus lumbosacralis. Neurological examination by a specialist is of significant importance preoperatively to determine the seat of the tumour and to assess the postoperative course.

Lumbosacral plexus lesions: correlation of clinical signs and computed tomography.

Neurological signs and computed tomographic morphology were compared in 60 patients. The primary neurological deficit was most commonly located in the sacral (n = 31) or lumbar plexus (n = 23) and was most commonly caused by a neoplasm (n = 40). In 78% of the patients it correlated with the lesions detected by computed tomography (CT). CT reliably demonstrates extraspinal mass lesions, but only moderately well predicts functional signs.

[Lumbosacral plexus block by the paravertebral route].

The authors present a detailed account of a technique of peripheric anesthesia of the lower limb, obtained with a single transcutaneous injection, blocking lumbar and sacral plexus, by a paravertebral way. Encouraging results have been reached in the treatment of both old (no cerebral or cardiorespiratory depressant effects) and young patients, which are frequently under day-hospital treatment. According to their experience, this technique is simple, easy to perform and less dangerous if compared to anesthesia obtained by spinal approach.

[Compression of the lumbosacral plexus in a case of voluminous aneurysm of the common iliac artery].

The clinical case presented is one of common iliac artery aneurysm, provoking a radicular compression symptomatology from L4 to S1. It is stressed that neurologic disorders having a radicular content are extremely rare in aorta-iliac vascular compressive pathology. In the case described, the involvement of several nerve roots is attributed to the aneurysm's unusual size (like a fetus' head) of the aneurysmatic sac.

Imaging in the exploration of lumbosacral plexus avulsion. Two cases.

In all cases of post-traumatic sensorimotor deficit in the lower limbs unexplained by another pathology, it is not unreasonable to suspect a nerve root avulsion. Whenever available, MRI seems to be the choice examination as it is not invasive and provides a three-dimensional exploration. On the basis of two new cases and a review of the literature, the authors discuss the value of various imaging methods in this pathology.

Ischaemic neuropathy of the lumbosacral plexus following intragluteal injection.

A lesion of the lumbo sacral plexus may result from an inadvertent intra-arterial injection of vasotoxic drugs into one of the gluteal arteries. Symptoms and follow-up of three cases are reported. The neuropathy is attributed to a toxic endarteritis with retrograde propagation of spasm and thrombosis. Swelling an bluish discoloration of the buttocks ("embolia cutis medicamentosa") as well as an impaired circulation in the homolateral leg are associated with the neurological syndrome in fully developed cases and makes possible a correct diagnosis.

Plasma prilocaine and mepivacaine concentrations after combined lumbosacral plexus block.

In a pharmacokinetic study of combined sciatic/3-in-1 block for lower limb surgery, the two moderate-acting local anaesthetics prilocaine and mepivacaine were compared. The mean maximum venous plasma concentrations of mepivacaine were more than twice as high as when prilocaine was used as anaesthetic (5.1 micrograms/ml vs. 2.37 micrograms/ml). When used in combination with the former, ornipressin did not reduce plasma concentrations of mepivacaine to values which were below the threshold for toxic symptoms (5-6 mg/ml). The peak plasma concentrations exceeded the threshold of 5 micrograms/ml in four of the nine patients of the mepivacaine group (maximum value 7.21 mg/ml) and in two of the nine patients of the mepivacaine+ornipressin group (maximum value 8.61 micrograms/ml).

Microsurgical treatment of lumbosacral plexus injuries.

Surgical treatment of lumbar and sacral plexus lesions is very rarely reported in the literature. The incidence of the involvement of these nervous structures in traumatic lesions of different etiology is probably much higher than believed, and surgical treatment should be taken into consideration more often. In this paper the experience derived from the surgical treatment of 15 cases is reported. Different surgical approaches have been employed according to ethiology, to level of nerve lesion and concomitant lesions of other organs. Patients who suffered a lesion in the lumbar or sacral plexus may have a very severe problem with deambulation since the leg may not be stable or may be unable to withstand the weight of the body. Pain syndrome in these patients may be a very severe obstacle to rehabilitation programs and to deambulation and everyday activity. Microsurgical nerve treatment in the retroperitoneal space is demanding both for the surgeon and for the patient but neurolysis and grafting procedures are possible also in this area. The resulting improvement of motor performance and the relief of pain are strong arguments in favor of this choice. Muscles benefitting most from surgery are the gluteal and femural muscles; more distant muscles, and particularly the anterior tibial nerve dependent muscles will gain minimal benefit from surgery. The relief from pain is relevant in all cases.
