Neurological complications after descending and thoracoabdominal aortic aneurysm (TAAA) correction procedures remain a serious challenge. Their prevention implies proactive approach to manageable risk factors: diagnosis and preoperative correction of latent renal failure [odds ratio (OR=4.72; p=0.08) and minimization the crossclamp time (OR=7.0; p=0.03). Extended TAAAs, especially type 1 and 2, (OR=8.5; p=0.03) must be operated only in facilities with sufficient experience in such reconstructions. Prognostic model was suggested to calculate precisely the risk of paraparesis. TAAA correction "without perfusion" is accompanied by 1.45 fold higher risk of neurological complications then after procedures that are accomplished under protection.

KEY WORDS: neurological complications, paraparesis, prognostication, thoracoabdominal aortic aneurysm, risk factors.
