Radial forearm free flap is the work horse in head and neck reconstruction. The venous drainage of the flap is by both superficial and deep group of veins.
Aim of the Study:
To compare the efficacy of venous drainage by single superficial vein (cephalic vein) with dual vein (cephalic vein & venae comitantes) in radial forearm free flaps and its impact on flap survival. Patient and methods- A total of 154 patients undergoing radial forearm free flap for reconstruction following resections of head and neck cancer were studied prospectively . In group 1 (75 cases) only cephalic vein was used as the draining vein and in Group 2 (79 cases) both cephalic vein & one venaecomitantes were used as the draining vein. Patients with non availability of cephalic vein as a result of chemotherapy or injury were excluded from the study. Data were retrieved frompatients' files and analyzed using SPSS computer software version 15.0.
Observation and Results:
The flap survival rate was 97.33% (73/75) in Group 1 versus 98.73% (78/79) in Group 2. The result is analysed statistically by using SPSS computer software version 15.0. and the
value > 0.50 (c
with Yates' correction=0.00206555, df=1) stastically not significant.
Though two vein anastomosis may provide a more fail safe theoretical advantage, single superficial vein (Cephalic) provides effective and adequate drainage with less operative time and no additional morbidity.
