Hemodialysis, also called dialysis, is the most common treatment for kidney failure. A dialysis machine is an artificial kidney which cleanses the blood. During dialysis, blood is drawn from the patient into the dialysis machine, circulated through the machine, and then returned to the patient. Two needles are inserted into the patient's bloodstream to allow this process to occur. Hemodialysis is normally performed three times a week and the purpose of vascular access is to provide reliable sites where the bloodstream can be easily accessed each time. There are three major types of vascular access: arteriovenous fistula, arteriovenous graft, and venous catheter. The great majority of vascular accesses are created in the arm, but they can also be created in the leg.
Indications for endovascular repair of the iliac artery are: Stenosis or (short-segment) occlusion of iliac artery (TASC type A and B, TASC C lesions are controversial) with ipsilateral lower extremity ischemia (lifestyle-limiting, progressive claudication, rest pain, gangrene). Patients with asymptomatic aneurysm greater than 4 cm in diameter. An iliac aneurysm which has also increased in size by 0.5 cm in last six months. Symptomatic iliac artery aneurysms mandate endovascular (or open) repair regardless of size. Patients with long occluded lesions/poor run-off/acute limb ischemia are poor endovascular candidates.
An excellent video demonstrating how a laparoscopy is performed to evaluate the uterus (note a small fibroid appearing as a bulge in the uterus), fallopian tubes and ovaries. Blue dye is injected into the uterus, entering the fallopian tubes and spilling from the end of the tubes into the abdominal cavity, confirming that both tubes are open
