Insights
This study used multidetector-row computed tomography angiography (MD CTA) to map popliteal artery variations. Many anatomical variations exist, impacting vascular procedures and surgical approaches.
Area of Science:
- Vascular anatomy
- Medical imaging
- Radiology
Background:
- Popliteal artery anatomy is crucial for vascular interventions.
- Previous studies have not comprehensively assessed popliteal artery variations using MD CTA.
- Understanding anatomical variations aids in surgical planning and procedural success.
Purpose of the Study:
- To establish the 3D CT anatomy of popliteal artery variations.
- To assess the prevalence and types of distal popliteal artery branching variations.
- To provide anatomical data for radiologists and vascular surgeons.
Main Methods:
- Retrospective review of 126 lower limbs that underwent CTA using 64-detector MDCT.
- Assessment of anatomical variations in the distal popliteal artery branching patterns.
- Utilizing multidetector-row computed tomography angiography (MD CTA) for detailed imaging.
Main Results:
- The typical branching pattern (Type 1 A) was observed in 83.6% of limbs.
- Variations were present in 16.4% of limbs.
- Common variations included a first branch of the tibial-peroneal trunk (Type 1 C) and a high origin of the tibialis anterior artery (Type 2 A II).
Conclusions:
- Significant variations in popliteal artery branching patterns exist.
- Knowledge of these variations is beneficial for radiologists and vascular surgeons.
- MD CTA is a valuable noninvasive tool for assessing distal popliteal artery variations.
Objective:
To date the anatomy of the popliteal artery variations using multidetector-row computed tomography angiography (MD CTA) was not assessed. The objective of this study is to establish 3D CT anatomy of the popliteal artery variations.
Materials And Methods:
A total of 126 lower limbs that underwent CTA using 64-detector MDCT were retrospectively reviewed. The anatomical variations of the distal popliteal artery branching were assessed.
Results:
Ninety-seven lower limbs (83.6%) had the usual branching pattern (type 1 A) with tibialis anterior artery (TA) arising first followed by the tibial-peroneal trunk, which then gives rise to the tibialis posterior artery (TP) and peroneal artery. Variations in popliteal branching pattern were seen in 19 (16.4%) limbs. The commonest variation was first branch of the TP in 5 (4.4%) of the limbs (type 1 C) or high origin with anterior course of popliteus muscle of the TA in 5 (4.4%) limbs (type 2 A II).
Conclusion:
Many variations exist in the running patterns of the branching pattern of the popliteal artery. Knowledge of the branching pattern of the popliteal artery will be beneficial to radiologist for the evaluation of CT angiograms and interventional vascular procedures, and to vascular surgeons for various surgical approaches. MD CTA provides noninvasive means of assessing distal popliteal artery variations.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
