Abstract
The aim of our study was to demonstrate, in vivo, bubble expansion in blood and to assess any damage to the arterial wall after 1 - 10 excimer laser pulses (55 mJ/mm2). Time resolved flash photography demonstrated the expansion and implosion of a vapor bubble, which induced a 50% diameter increase of the artery within 75 microsecond(s) and a subsequent invagination (150 - 500 microsecond(s) ). This microsecond dilation and invagination caused extensive wall damage (up to 1.9 mm) far beyond the penetration depth of 308 nm laser light (< 100 micrometers ). The damage, which increased with the number of laser pulses, may be related to the dissections observed after excimer laser coronary angioplasty.
