Objective:
To evaluate the efficacy of venous free thenar flaps for reconstructing palmar soft tissue defects in fingers.
Methods:
From December 2018 to October 2019, 11 patients with palmar soft tissue defects in fingers were treated using venous free thenar flaps. At the final follow-up, the range of thumb radial and palmar abduction on the injured side and opposite side was calculated. The total active movement (TAM) of the injured and opposite fingers and flap sensibility recovery were also recorded.
Results:
The mean follow-up time was 13.4 months, all flaps survived, and all wounds at the donor sites healed with no skin necrosis. At the last follow-up, the average range of thumb radial abduction and thumb palmar abduction on the injured side was 96.6% and 95.9% of the value on the opposite side, respectively. The average TAM of the injured fingers was 98.2% of the value of the opposite fingers. Sensation in the flaps was restored to grade S2 to S3.
Conclusion:
Venous free thenar flaps can be alternatives for reconstructing palmar soft tissue defects in fingers.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
