Perforator Artery Changes During Suprafascial Pre-expansion of the Perforator Flaps

This study has been completed.

Tissue expansion methods have been recommended as a means of improving the clinical results with perforator flaps but in plastic surgery literature there are few clinical trials supporting this opinion. The purposes of this clinical study are to address the ''preexpanded perforator flap concept'' by demonstrating a case series of relevant reconstructive procedures and to evaluate the perforator vessel changes that happen during the expansion periods of various perforator flap donor sites.

Condition Intervention
Scar Contracture Flap Disorder Procedure: preexpanded perforator flap surgery

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment

Further study details as provided by Emre Hocaoglu, Istanbul University:

Primary Outcome Measures:
  • Transferred tissue dimensions [ Time Frame: At least five months after the operation ]
    Demonstrating the amount of transferred healthy tissue exhibits the success of the technique.

Secondary Outcome Measures:
  • Diameter of the perforator artery in a particular tissue level [ Time Frame: Measured the day before the expander implantation surgery and the day before the flap transfer surgery (second session following tissue expansion) ]
    This measurement will reveal one of the morphologic changes happen during tissue expansion period (perforator flap preexpansion). This measurement will be done for the last six patients. The diameter of the perforator artery of the preexpanded flap will be compared with both the diameter of the same artery before the expansion process and the diameter of the equivalent perforator artery of the symmetric side (non expanded side)of the body.

Enrollment: 14
Study Start Date: June 2009
Study Completion Date: January 2013
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: preexpanded flap
Fourteen patients were treated with fifteen '' preexpanded perforator flap surgery '' interventions. The last six cases were evaluated in terms of perforator artery diameter before and after expansion process. The preexpanded flap donor sites' perforator artery diameters were also compared with their anatomic equivalents located in the symmetric side of the body.
Procedure: preexpanded perforator flap surgery
No Intervention: control side
In six of the 14 patients, perforator artery diameter of the nonexpanded symmetric anatomical side of the body (equivalent to the expanded site)were measured.
