“…16,17 In the mid-1970s, angiography considered to be the gold standard was supplanted by the use of digital subtraction angiography (DSA) to determine vascular anatomy used in flap design, particularly for the lower extremities. 18,19 Use of the color Doppler scanner in flap design was later introduced in the 1980s and became a popular mapping technique in the 1990s 17,20 Masia et al described the use of computed tomography (CT) in the planning of perforator flaps in breast reconstruc-tion. 21 Around the same period, magnetic resonance angiography (MRA) was introduced to localize perforators.…”

“…4). 41,44,45 Conventional angiography offers high resolution, realtime imaging that enables careful evaluation of both large vessels and smaller perforators. The ability to demonstrate vessel flow dynamics may give invasive angiography a slight advantage over some of the newer imaging techniques, particularly with regard to recipient vessel selection.…”

Background The benefits of preoperative perforator imaging for microsurgical reconstruction have been well established in the literature. Methods An extensive literature review was performed to determine the most commonly used modalities, and their applicability, advantages and disadvantages. Results The review demonstrated varioius findings including decreases in operative time and cost with the use of CT angiography to identification of perforators for inclusion in flap design with hand-held Doppler ultrasound. Modalities like MR angiography offer alternatives for patients with contrast allergies or renal dysfunction while maintaining a high level of clarity and fidelity. Although the use of conventional angiography has decreased due to the availability of less invasive alternatives, it continues to serve a role in the preoperative evaluation of patients for lower extremity reconstruction. Duplex ultrasonography has been of great interest recently as an inexpensive, risk free, and extraordinarily accurate diagnostic tool. Emerging technologies such as indocyanine green fluorescence angiography and dynamic infrared thermography provide real-time information about tissue vascularity and perfusion without requiring radiation exposure. Conclusion This article presents an in-depth review of the various imaging modalities available to reconstructive surgeons and includes hand held Doppler ultrasound, CT angiography, MR angiography, conventional angiography, duplex ultrasonography, Indocyanine Green Fluorescence Angiography and Dynamic Infrared Thermography.

“…18 Around the same period, angiography, later replaced by DSA, was introduced to assess the vascular anatomy of flaps, mainly in the lower extremities. 19,20 The use of CDS in the planning of flaps was first described in the 1980s and became a common mapping method in the 1990s. 21,22 In the last decade, major progress has been made in the applicability of, especially, CTA and MRA.…”
