Abstract/OtherAbstract:
BACKGROUND:: Results of vascular anatomy studies of the lower limb in the past have been primarily descriptive in nature and are therefore less useful in directing the design of local perforator-based flaps. The purpose of this study is to document the three-dimensional anatomy of the cutaneous perforators arising from the anterior tibial, posterior tibial and peroneal arteries and provide a statically verified method for predicting perforator location for use in the clinical setting. METHODS:: CT angiography and 3-D reconstructions of the lower limb using MIMICS software were completed for 5 lead oxide-injected cadavers. The cutaneous perforators of the vessels of the tibial trunk were identified and perforator diameter, course and location relative to leg length were determined. Cluster analysis was performed to evaluate the consistency of perforator locations across individuals. RESULTS:: The ATA had the greatest number of perforator vessels, which clustered into three groups centered at: 83% ± 6 (percent of tibial height ± standard deviation), 59% ± 7, and 28% ± 9. PA perforators were clustered in two groups centered at 61% ± 9 and 27% ± 11. The PTA perforators could also be divided into two groups, however a larger standard deviation in the two groups suggests that perforators arising from this vessel are more evenly spaced. CONCLUSIONS:: Statistical analysis demonstrated that the major perforator vessels of the tibial trunk are conserved across individuals, and can be reliably dissected using the cluster's statistical distribution. Results of this study will allow for better preoperative planning of local flaps. LEVEL OF EVIDENCE:: Not gradable.
