Neurovaskuläre Therapieoptionen bei komplexen Aneurysmen der Arteria carotis interna // Neurovascular therapeutic options in complex intracranial aneurysms Journal für Neurologie, Neurochirurgie und Psychiatrie 2021; 22 (3): 128-134 Volltext (PDF) Summary Praxisrelevanz Abbildungen
Keywords: endovaskuläre Therapie, Flowdiverter, kombinierte Behandlung, Neurochirurgie, Riesenaneurysma, zerebraler Bypass, combined treatment, endovascular treatment, extra-intracranial bypass, flowdiversion, giant aneurysm Complex intracranial aneurysms (CIAs) rank high among the most technically demanding neurovascular lesions. Beside morphological factors like size, fusiform configuration, partial thrombosis or wall calcification internal carotid artery CIAs are also difficult to treat, because of their limited surgical accessibility due to their intimate relationship and extension to the skull base. During a conference we currently had the opportunity to review the work specifically dealing with therapeutic neurovascular options available for the treatment of CIAs that was published by different authors from the Medical University of Vienna at the Neurosurgical Department over the past four centuries. The options span from direct microsurgical clipping using advanced skull base techniques over selective endovascular coiling with or without stenting to well proven combined (hybrid) procedures like bypass-supplemented parent artery occlusion and the recently introduced endoluminal flowdiversion using specially designed stents. Taking advantage from the complementary interaction of endovascular and surgical technologies the pro and cons are discussed by two hybrid vascular neurosurgeons cross-experienced in both techniques. Today safe and durable clinical and radio-anatomical results can be achieved in these difficult to manage CIAs by careful patient selection and the availability of a spectrum of neurovascular therapeutic options, which use all possible avenues to reach the ultimate goal for the patient, namely a satisfying clinical and radio-anatomical result.
Kurzfassung: Schwierig zu behandelnde, komplexe,
intrakranielle Aneurysmen (CIA) stellen
für den vaskulär tätigen Neurochirurgen nach
wie vor eine große Herausforderung dar.
Neben Größe, fusiformer Konfiguration, Teilthrombosierung
oder Wandverkalkung ist die
proximale schädelbasisnahe Lokalisation bei
CIAs der Arteria carotis interna (ACI) ein weiterer
komplizierender Faktor für ihre Behandlung. |
