Usefulness of the Lone Star Retractor System for harvesting the superficial temporal artery: technical note.

ABSTRACT

Harvesting the superficial temporal artery (STA) is the first difficult step in extracranial-intracranial bypass surgery. There are various methods and instruments for harvesting the STA. We used the Lone Star (LS) retractor system for harvesting the STA. The LS retractor system is used in other surgical specialties. The LS retractor system consists of the retractor ring (14.1 cm × 14.1 cm) and elastic stays (5-mm sharp hook). The retractor ring can be used to adjust to the operative field. Retracting the loose connective tissue around the STA by the elastic stays can make harvesting the STA easy and safe. After harvesting the STA, retracting the skin and muscle by the elastic stays is useful for hemostasis during intracranial surgery and anastomosis. We used the LS retractor system in 26 consecutive patients to perform STA-MCA anastomosis between November 2015 and August 2018. All STAs were harvested without complications or injuries. The LS retractor system is a safe and useful method for harvesting the STA.
