“…Superficial thrombophlebitis is one of the most significant complications of superficial vein thrombosis, with an incidence of about one per 1000, 1 which may lead to peripheral artery disease, 2 superficial calcification, 3 and/or pulmonary embolism. 4 Rapid imaging and mapping with high resolution of the superficial vasculature is particularly important for accurate diagnosis so as to carry out treatment as soon as possible. To confirm the diagnosis, numerous advanced instruments, including duplex ultrasound, 5 optical frequency domain imaging, 6 positron emission tomography (PET), and computed tomography (CT) angiography, 7 are often used in clinical diagnosis.…”
