    Description / Table of Contents: Zusammenfassung Bei einem 15jährigen Jungen mit jevenilem Diabetes mellitus entwickelte sich im Zusammenhang mit einer rezidivierenden Racheninfektion ein großes schädelnahes Aneurysma im Endabschnitt der extrakraniellen A. carotis interna. Durch Eröffnung des Karotiskanals wurde ein anastomosenfähiges, distales Gefäßende hergestellt und die Strombahn durch ein autologes Veneninterponat rekonstruiert. Der postoperative Verlauf war bis auf eine periphere Faszialisparese ohne Komplikationen, die postoperative Arteriographie zeigte normale Gefäßverhältnisse.
    Notes: Summary A 15-year-old diabetic boy suffering from recurrent peritonsillar infections developed a mycotic aneurysm of the internal carotid artery at the base of the skull. The aneurysm was approached through a cervical and retroauricular incision. The styloid process was burred down at its base. The sternocleidomastoid muscle and the digastric muscle were resected from the mastoid. The internal carotid artery was clamped proximally and blocked with a balloon-catheter distally. The carotid bone canal was opened 10 mm and the carotid artery resected until normal vessel wall was reached. A vein graft was placed end-to-end with single stitches, using 8×0 monofil sutures with a small neddle. The postoperative course was uneventful except for a temporary paresis of the peripheral facial nerve. Postoperative angiography revealed restoration of the vessel to normal, the patient is now free of symptoms.

    Description / Table of Contents: Zusammenfassung Zur Bestimmung des Stenosegrades wurden Dopplersonographie und intraoperative Druckmessung mit der Standard-II-Ebenen Angiographie verglichen. Gruppe 1 (Stenose kleiner als 80 %): Doppler/Angio 63% (positive Korrelation); Druckgradient/Angio 84%; Doppler/Druckgradient 77%; mittlerer Gradient 12 mm Hg. Gruppe 2 (Stenose groβer als 80 %) : Doppler/Angio 82 %; Gradient/Angio 72 %, Doppler/Gradient 64 %, mittlerer Gradient 25 mm Hg. Die funktionelle Signifikanz der Stenose nahm bei geringerem Kollateralfluß zu, kenntlich an der dopplersonographischen ≫Überschätzung≪ und an einem relativ großen Gradienten. Aus klinischer Sicht sind Einengungen größer als 80 % ≫kritisch≪ und erfordern sofortige chirurgische Therapie, da in 4 von 15 Patienten lokale Verschlüsse auftraten, welche gerade noch rechtzeitig operabel waren.
    Notes: Summary The results of indirect and direct Doppler examination and pressure gradient determination were compared with the bilateral angiography in 50 patients with internal carotid artery stenosis. Group 1 (stenosis below 80 % square area reduction) : the accuracy of Doppler vs angiography was 63 %, pressure gradient vs angiography 84%, Doppler vs pressure gradient 77%, mean gradient 12 mmHg. Group 2 (more than 80% square area reduction), Doppler vs angiography 82 %, pressure gradient vs angiography 72 %, Doppler vs pressure gradient 64 %. Mean pressure gradient 25 mm Hg. In conclusion, every lumen reduction of more than 80 % is critical and surgical therapy is urgent, since sudden local occlusion occurred in 4 of 15 patients.
