A male patient required a hand amputation after a sclerotherapy procedure ineffectively treated his varicose veins. A foam solution had been injected into the patient’s vein in order to cause blood clotting and reduce the vein’s visibility. However, the patient’s hand began to swell and turn a mottled purple, causing him to contact the Nurse Hotline. Consequent imaging in the hospital’s emergency services revealed that arteries providing blood to the man’s hand had been clamped shut, potentially by the previously administered foam treatment. Though multiple attempts were made to reopen the patient’s arterial veins, he eventually required amputation of three fingers on his writing hand. He alleged he had been given poor medical care, and decided to sue the physician who had administered his sclerotherapy.
