A 3D reconstruction of angiography from the aortic arch to the upper limb, whether for the right, left, or both sides, provides a comprehensive view of the arterial pathway linking the heart to the arm, forearm, and hand. The model begins with the aortic arch, a curved structure ascending from the heart, which gives rise to three major branches: the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. For the right upper limb, the brachiocephalic trunk is depicted branching into the right subclavian artery, while on the left, the subclavian artery arises directly from the aortic arch. The reconstruction follows the subclavian artery as it passes over the first rib and under the clavicle, transitioning into the axillary artery within the axilla. This artery continues as the brachial artery along the humerus, a prominent vessel that bifurcates at the elbow into the radial and ulnar arteries. These arteries are shown extending through the forearm—the radial artery laterally and the ulnar artery medially—before forming the superficial and deep palmar arches in the hand, with smaller digital branches supplying the fingers. The 3D view captures additional tributaries like the thyrocervical trunk or deep brachial artery, illustrating the rich collateral network. This detailed visualization highlights the vessels’ trajectories, diameters, and potential abnormalities such as aneurysms, stenoses, or atherosclerotic plaques, offering critical insights into vascular conditions affecting the upper limb, such as subclavian steal syndrome or embolism. By tracing the arterial continuum from the aortic arch to the distal extremities, this reconstruction serves as a vital tool for understanding circulation dynamics and planning interventions like stenting or bypass surgery.
