Helicine arteries of penis Helicine arteries of penis The helicine arteries of penis are arteries in the penis. They are found in the corpora cavernosa penis. They are involved in the process of erection. On entering the cavernous structure from the deep artery of the penis the arteries divide into branches, which are supported and enclosed by the trabeculae. Some of these arteries end in a capillary net-work, the branches of which open directly into the cavernous spaces; others assume a tendril-like appearance, and form convoluted and somewhat dilated vessels, which were named by Rosenmüller "helicine arteries". These arteries have two unique features: an
Dextro-Transposition of the great arteries to stretch open a stenotic vessel; this relieves restricted blood flow, which could otherwise lead to congestive heart failure ( CHF ). An endovascular stent is sometimes placed in a stenotic vessel immediately following a balloon angioplasty to maintain the widened passage. Angiography involves using the catheter to release a contrast medium into the chambers and/or vessels of the heart; this process facilitates examining the flow of blood through the chambers during an echocardiogram, or shows the vessels clearly on a chest x-ray, MRI, or CT scan - this is of particular importance, as the coronary arteries must be carefully
