Pseudoaneurysms are mostly pulsatile masses caused by trauma, infection, etc. Whether surgery is needed for pseudoaneurysms of the wrist needs to be judged according to the size and morphology of the tumor. Pseudoaneurysms of the wrist require a physical examination, color ultrasound Doppler, and computed tomography angiography to confirm the size and shape of the aneurysm and to evaluate the treatment method. If the aneurysm is small and the risk of rupture is small, conservative treatment to observe the changes of the pseudoaneurysm and regular checkups will be sufficient. If the aneurysm is large, the risk of rupture will increase accordingly, and surgical treatment will be required, which should be decided by a professional doctor. Some pseudoaneurysms may lead to shock, hemorrhage or even life-threatening, and it is recommended to consult a doctor for timely treatment of pseudoaneurysms in the wrist to avoid delaying the condition.
