I will breakdown you question and give it me my all.
Arteriosclerosis obliterans is an occlusive arterial disease most prominently affecting the abdominal aorta and the small- and medium-sized arteries of the lower extremities, which may lead to absent dorsalis pedis( is a blood vessel of the lower limb that carries oxygenated blood to the dorsal surface of the foot. It arises at the anterior aspect of the ankle joint and is a continuation of the anterior tibial artery. It terminates at the proximal part of the first intermetatarsal space, where it divides into two branches, the first dorsal metatarsal artery and the deep plantar artery), posterior tibial, and/or popliteal artery pulses.
Iliac vessels can refer to:
Iliac artery--refers to several anatomical structures located in the pelvis:
-Common iliac artery - forms at terminus of the aorta.
-External iliac artery - forms when the common iliac artery bifurcates, continues as the femoral artery at the inguinal ligament.
-Internal iliac artery - forms when the common iliac artery bifurcates, supplies the perineum a
-External iliac vein - terminates at the common iliac vein, drains the femoral vein.
-Internal iliac vein - terminates at the common iliac vein, drains pelvic organs and perineum.
-Common iliac vein - formed by the external and internal iliac veins, drains into the inferior vena cava.
Subcortical cysts ; it is a collection of pus underneath the cerebral cortex it is dangerous.-
A cyst is a closed sac, having a distinct membrane and division on the nearby tissue. It may contain air, fluids, or semi-solid material. A collection of pus is called an abscess, not a cyst. Once formed, a cyst could go away on its own or may have to be removed through surgery.
