...column of mercury. To use it, the doctor pumps air into a cloth cuff wound tightly round the patient's arm. As the cuff expands, the column of mercury rises in response to the increasing air pressure. That pressure also causes the cuff to press against the brachial artery, stopping the flow of blood. The doctor, his stethoscope pressed against the patient's forearm, knows that the flow has ceased when he can no longer hear the heartbeat. At that point, he slowly releases the air from the cuff. As pressure drops, the mercury column begins to descend...
...sure the blood would have a way to get out. With neat and delicate sutures, they stitched the arm's two main veins to their extensions in Ev's shoulder (see diagram). Next, they opened a way for the blood to get in by rejoining the major (brachial) artery. Says Dr. Shaw: "When we took off the clamps from the artery above the break, we rejoiced at the pinking up of the arm as the blood ran through it." It was just 3½ hours since Ev Knowles's arm had been severed...
Simple Dexterity. Prime element in he Sones-Shirey method is the catheter, a snakelike, 31-in. tube that tapers in diameter from 3.2 mm. down to 1.6 mm. at its tip. The catheter is first inserted in the patient's brachial artery, inside the elbow of the right arm, and maneuvered up the arm into the chest, until its passage is stopped by the aortic valve, directly above the heart. Except for a dull ache in the elbow (local anesthesia is administered) the operation is painless Because the arterial nerves are insensitive to the catheter's presence...
After 700 operations on 350 dogs, Dr. Beck was ready last January for a human patient. First he cut a piece about two inches long out of the brachial artery, which supplies the arm; the arm has plenty of blood supply and would not be crippled. Then he used the borrowed segment to make a new channel connecting the aorta, the body's main artery, with the coronary sinus, the heart's main vein. He thus reversed the normal course of the blood and made it flow backward.. In effect, he turned a vein into an artery...
...until it gets stuck in an artery. Most frequent sites of this plugging are the common femoral artery in the groin (39%) and the common iliac artery in the lower abdomen (15%). Embolus here stops circulation in the entire leg and foot. Other frequent sites for emboli are the brachial artery in the elbow, affecting the forearm and hand; the popliteal (10%), affecting the lower leg and foot; the aorta, affecting the entire body...
