Abstract
Background Microsurgical anastomosis is a delicate, highly nuanced procedure that can be done
in several different ways; the most basic approach to performing microsurgical anastomoses
is by using simple interrupted sutures, but even within that approach, there are different
sequences by which the sutures can be placed. To date, there is no review of these
sequences and the advantages and disadvantages of each.
Methods A PubMed search was performed in October 2019 that sought all published descriptions
of simple interrupted microsurgery techniques. Keywords included were “microvascular
anastomosis,” “microvascular anastomosis technique,” “simple interrupted,” and “microsurgery.”
Results Four simple interrupted microsurgery techniques were identified: triangulation, 12
o'clock to 6 o'clock, posterior-wall-first, and 3 o'clock to 9 o'clock-side-side.
Additionally, there is no uniform nomenclature that describes the techniques for simple
interrupted microvascular anastomoses.
Conclusion This study identified four distinct sequences for the placement of simple interrupted
sutures for microsurgical anastomosis and the advantages and disadvantages of each,
and for the first time described them utilizing standardized nomenclature.
