Background
Double superficial temporal artery (STA) to middle cerebral artery (MCA) bypass surgery has typically involved more than one
linear incision. In this report, we demonstrate how the procedure can be performed through a single linear skin incision over
the parietal branch of the STA.
Methods
Initial dissection of the parietal branch and creation of a subcutaneous cavity along the frontal branch were performed using
the conventional microscopic method. Detailed additional dissection and isolation of the frontal branch were accomplished
with the aid of an endoscopic retractor.
Results
This procedure was performed in five patients for harvesting of approximately 8- and 5-cm lengths of the parietal and frontal
branches, respectively. The resultant lengths of the harvested vessels were sufficient for anastomotic revascularization of
MCA recipient arteries in both the frontal and temporal lobes.
Conclusion
This method can be safely performed with achievement of a less invasive dissection of the STA and an overall improved cosmetic
outcome.
