Abstract

Partial removal of nucleus pulposus with consequent reduction of intradiscal pressure may be obtained with percutaneous intradiscal administration of chemical substances in the intervertebral disc. We used percutaneous intradiscal injection of radiopaque gelified ethanol (“Discogel”) in 72 patients (group 1) with conservative treatment resistant lumbar and radicular pain due to small and medium-size hernias of intervertebral disc to demonstrate its efficacy and safety vs. 72 subjects treated with intra-foraminal and intradiscal injections of a steroid and anesthetic (group 2 or control group). “Discogel” injection was performed with biplane fluoroscopy assistance and under local anesthesia with patient in lateral position on symptomatic side. Amount of “Discogel” injected ranged from 0.8 ml to 1.6 ml. We treated a total of 83 discs. We performed the procedure on one disc in 62 patients; in 9 patients two discs were treated in the same session and in 1 patient three levels were treated in two separate sessions. In group 1 patient “responders” were 65 (90.3%). Excellent and good results were obtained in 58 patients (80.4%), satisfactory results in 7 patients (9.8%) and poor results in 7 patients (9.8%); among “responders” pain control was quite immediate in 58 patients (89.3%) while in 7 patients (10.7%) there was a delay of 7-10 days. These values were significantly higher than in control group. Also the quality of life was significantly more sustained vs. control group, and this benefit was maintained over time. Concerning complications, in 3 cases (4.15%) we had transitory radicular irritation with neuropathic pain appearance immediately after the procedure and in 1 case (1.30%) transitory sensory-motor deficit due to diffusion of local anesthetic along the introducer needle. In conclusion intradiscal radiopaque gelified ethanol injection is minimally invasive, low cost, safe and effective procedure that may be considered in proper selected patients before recourse to surgery.

34. Il trattamento endovascolare dell'aneurisma della vena di Galeno: Descrizione di un caso

Author

Battistella, P.A., Fiore, D.L., Pellone, M., and Pardatscher, K.

Abstract

L'aneurisma della vena di Galeno (AVG) è una rara condizione malformativa artero-venosa cerebrale: essa è caratterizzata dalla presenza di shunts artero-venosi unici o multipli a livello della parete della vena mediana del prosencefalo. L'espressione clinica dell'AVG è età dipendente: in età neontale si manifesta con scompenso cardiaco, nell'infanzia con macrocefalia, idrocefalo sopratentoriale ostruttivo da compressione dell'acquedotto ed eventuali manifestazioni convulsive secondarie ad emorragie. Può rimanere, peraltro, anche a lungo silente, determinando solo in età giovanile-adulta cefalea, sintomi neurologici focali o manifestazioni convulsive causate da sanguinamenti. La mortalità per tale patologia non trattata è elevata, specie nelle forme ad esordio neontatale. Viene presentato un paziente di 8 anni con riscontro di AVG di tipo murale alla RM eseguita per cefalea ricorrente e macrocefalia, uniche manifestazioni cliniche della malformazione vasculare.Nel corso di 3 sedute di terapia endovascolare per via arteriosa vengono esclusi i 5 peduncoli afferent all'AVG (4 a partenza dall'arteria cerebrale posteriore destra ed 1 a partenza dalla arteria cerebrale posteriore sinistra), ottenendo sia la guarigione angiografica della lesione vascolare, sia la completa remissione della sintomatologia cefalalgica, senza alcuna complicanza.Vengono quindi discussi: a) i differenti quadri anatomo-patologici dell'AVG secondo le più recenti classificazioni; b) le diverse tecniche diagnostiche utilizzabili a seconda dell'età; c) i diversi approcci del trattamento chirurgico ed endovascolare (arterioso e venoso), confrontando rischi e risultati; d) i rischi della derivazione liquorale rispetto all'approccio diretto sull'AVG.L'embolizzazione rappresenta attualmente la metodica terapeutica più valida nella cura di questa patologia, grazie soprattutto ai progressi tecnici per quanto riguarda sia i materiali impiegati per il cateterismo superselettivo dei vasi cerebrali, sia i diversi agenti embolizzanti (NBCA, «Coils»). Tale trattamento è in grado di dare risultati eccellenti quali l'esclusione morfologica completa dell'AVG e percentuali di miglioramento in oltre il 50% dei casi, con trascurabile morbilità e drastica riduzione della mortalità rispetto ai soggetti operati o non trattati.

35. Il ruolo della tomografia RM e dell'Angio-RM nello studio degli aneurismi cerebrali

Author

Fera, F., Armentano, A., Bartone, P., Ginolfi, G., Ceccotti, C., and Pardatscher, K.

Abstract

To evaluate the reliability of magnetic resonance angiography for detecting intracranial aneurysms a prospective study was performed in 21 consecutive patients affected by SAH and in 13 patients in whom aneurysms were suspected on standard SE RM. In the SAH cohort 8 of 21 clearly showed an aneurysm, 3 of 21 were doubtfull. In the 13 patients without SAH, aneurysms were confirmed in 12. Due to flow artefacts in the small aneurysms a deceptive pseudoloop pattern was often observed.

36. Clotting Changes in Two Patients with Longitudinal Sinus Thrombosis

Author

Girolami, A., Pardatscher, K., Scanarini, M., Job, I., and Patrassi, G.

Abstract

Two patients with angiographically proven longitudinal sinus thrombosis were studied from a coagulation point of view. In the first case, marked primary thrombocytosis was found. This patient was treated with aspirin, dipyridamole and radioactive phosphorus. In the second case, fibrinogen and whole blood plasma viscosity were elevated. This patient developed deep vein thrombosis of the left leg a few weeks after the cerebral episode and was treated with coumarin drugs. The importance of a coagulation study in every patient with cerebral vein thrombosis is emphasized.

Abstract

A series of 24 children with anterior optic gliomas, observed and for the most part operated upon in a neurosurgical service, is reviewed. A low incidence of unilateral nerve tumors and of associated neurofibromatosis, and a rather high frequency of precocious or pseudoprecocious puberty were noted in comparison with other series. Most tumors were low-grade growths. The results of surgical treatment reflect a good prognosis for unilateral tumors and an increasing prognostic ominousness for the posterior neoplastic development. Cerebrospinal fluid shunts and radiation treatment do have a role as adjuncts to surgical exploration and biopsy, which are generally indicated since no preoperative test seems to grant an absolute diagnosis. The opinion that chiasmal tumors should not be treated at all is not shared. When the treatment of an illness falls as far short of the ultimate, as does the therapy of neoplastic disease, then it is necessary to reconsider frequently the principles upon which it is based and the results it achieves. These results are two-fold, curative and palliative and, while our efforts are directed toward the former, we realize only too frequently that the best results will sometimes lie in palliation. The disappointment in accepting this lesser goal must not allow us to underestimate its importance or neglect the help it may give.
