Assessment of the patency of microvascular anastomoses using microscope‐integrated near‐infrared angiography: A preliminary study

Abstract

: Hand-sewn anastomoses are subject to technical errors, and conventional patency tests have a low sensitivity for revealing anastomotic failure. Microscope integrated microangiography is an excellent method for identifying significant anastomotic problems, which would have otherwise gone unnoticed. The potential impact on early flap failure and reexploration surgery is considerable. (c) 2009 Wiley-Liss, Inc. Microsurgery 2009.

The intrinsic transit time of free microvascular flaps: Clinical and prognostic implications

“…We recently described a new method of microscope-integrated indocyanine green near-infrared videoangiography (ICGA) for the intraoperative visualization of vascular flow through microvascular anastomoses. 1 As angiography of vessels with submilimeter diameters was previously not available, this study provided significant new knowledge on patency rates in routine microvascular procedures. The need for objective intraoperative patency assessment was highlighted by a significant discrepance between the results of conventional clinical patency tests and angiographic findings.…”

Use of optical magnification and microsurgical technique in general surgery

“…The use of microsurgery in limb transplants and microvascular free flaps has now been standardized and used for many years. [1][2][3][4] On the other hand, a special emphasis must be put on the advantage that can be achieved by the use of optical magnification during microsurgery operations, in general surgery.…”

Intraoperative free jejunum flap monitoring with indocyanine green near-infrared angiography

“…Fully perfused dye gradually diminished from the jejunum graft ( Fig with the clinical outcome [5]. Since then, the availability of ICGA for intraoperative free flap monitoring has been demonstrated [6,7]. However, the application of this technique for a free jejunum graft has not been reported to date.…”
