Pulmonary edema cardiac arrest due to hypoxia. It is a cardinal feature of congestive heart failure. The term edema is from the Greek (oídēma, "swelling"), from οἰδέω (oidéō, "I swell"). The most common symptom of pulmonary edema is difficulty breathing, but may include other symptoms such as coughing up blood (classically seen as pink, frothy sputum), excessive sweating, anxiety, and pale skin. Shortness of breath can manifest as orthopnea (inability to lie down flat due to breathlessness) and/or paroxysmal nocturnal dyspnea (episodes of severe sudden breathlessness at night). These are common presenting symptoms of chronic pulmonary edema due to left ventricular failure.
Reinke's edema bilateral - effecting both vocal cords - rather than unilateral. In the case of bilateral edema, the surgeon must choose whether to operate each side of the vocal cord in two separate surgeries or to operate both sides in a single surgery. The complication associated with removing tissue from both sides in a single surgery is that the raw, cut ends of the vocal cords may form an anterior glottis web, in which the two sides grow together in a continuous sheet. Other complications of surgery include tissue scarring due to damage to the vocal ligament during the incision and
