Angiography
Abbildung 2: Follow-up angiography showed hazy lesion distal of the stent with significant luminal narrowing, followed by long diffuse lesion


Keywords: Angiographie,  Läsion

OCT
Abbildung 3: OCT run after NC dilatation: (a) Significant deep medial dissection starting < 5 mm from distal stent edge with apparent inlet. In L-Mode flap appears long and significantly protruding with risk of lumen occlusion (* = wire artifact). (b) Intramural hematoma (separation of IEL and EEL) from 12 to 3 o’clock and lipidic plaque from 6 to 9 o’clock and significant luminal narrowing. (c) Hematoma is partially evacuated after NC-ballooning.

Ballon
Abbildung 5: Cutting balloon can create multiple fenestrations between the true lumen and intramural hematoma: If expansion is not effective, “cuttering” technique (pulling cutting balloon back along hematoma at low pressure) can help [4].
