The prog­nos­tic mean­ing of the rou­tine use of the meth­ods of tem­po­rary clip­ping of the affer­ent ves­sel in ­patients ­with intra­cra­ni­al aneu­rysm (Grading 0-III) was the aim of the anal­y­sis in ­this ­study. In the peri­od 1 January, 1991-31 December 1997, 304 ­patients under­went sur­gery for non-­giant intra­cra­ni­al aneu­rysm and a fol­low-up angio­gra­phy. 157 ­patients ­were oper­at­ed by rou­tine­ly ­using the tem­po­rary clip­ping of the affer­ent ves­sel, where­as in 147 ­patients the sur­gi­cal pro­ce­dure was per­formed by tra­di­tion­al meth­ods. The sta­tis­ti­cal anal­y­sis ­showed a sig­nif­i­cant reduc­tion (p<0,001) in ­terms of ­risk of sur­gi­cal com­pli­ca­tions in the ­patients who under­went sur­gery ­with the tem­po­rary ­clip meth­od com­pared to ­those oper­at­ed ­with the tra­di­tion­al meth­od, ­with a rel­a­tive ­risk of ­such com­pli­ca­tions ­about ­three ­times great­er in the lat­ter. The rou­tine use of tem­po­rary clip­ping ­offers, there­fore, the pos­sibil­ity of a sig­nif­i­cant improve­ment of the sur­gi­cal ­results, not influ­enced by a fur­ther involve­ment for the struc­ture, due to the ­short appli­ca­tion ­time.
