Abstract

Background: Soft tissue defects in the hand can result
from a varietyof mechanisms including trauma, infection, and
malignant tumors. Propeller flaps have become an appealing
option for coverage of a large range of defects. The aim of
this study is to determine the effect of dissected length of the
perforator and its diameter and the angle of rotation or twisting
of the flap on the blood flow in this chosen perforator and
the flap vascularity.
Methods: Thirty cases of skin and soft tissue defects of
the hand and wrist were reconstructed with a perforator-based
propeller flap from the radial artery in the period from May
2016 to November 2019. The age of patients ranged from 15
to 60 years. The defects were on the dorsal or palmer aspect
of the hand and wrist. We evaluated the viability of the
flap,blood velocity and flow of the flap, survived area of the
flap according to length and diameter of the chosen perforator
and the angle of rotation of the flap.
