Oh my god , oh my god , oh my god . Here ’s a telecasting of a catheter , come in in a femoral arterial blood vessel , going up to a person ’s eye . Again , oh my god .
There ’s an actual reason for this . Retinoblastoma is cancer of the retina , the layer of light - sense cells at the back of the oculus . Fortunately , the treatment of such cancers has progress to the point where patients have a great than ninety - nine per centum survival pace . Unfortunately , treatment normally lead to loss of at least some visual sensation .
In essay to retain visual sensation , while maintaining high-pitched survival rate , scientist have come up with a new technique . It delivers chemotherapy in a very targeted fashion , but from a very remote placement . grant to the description of the surgery , this is what happens :
In brief , affected role are invest under general anesthesia and canulate . The interventional radiologist incisively lay a microcatheter via a transfemoral artery approach under direct fluoroscopic visualization at the ostium of the ophthalmic artery ( but not more distal ) , which allow selective delivery of chemotherapeutics to the eye via its primary arterial provision .
The transfemoral arteria is in the thigh . This means we have TV of a catheter travel through the intact chest , across the middle of the chest , up the neck , and into the center of the patient . I discover the video unreasoningly ugly , but at the same time amazing . It ’s startling to see how a solid object can make its fashion through a human body . What do you consider ?
