The role of thoracic aortic occlusion for massive hemoperitoneum.

Forty patients with abdominal injury and massive hemoperitoneum had left thoracotomy and thoracic aortic occlusion. All 40 patients had tense abdominal distention and 37 patients were hypotensive at the time of skin incision despite aggressive resuscitation with blood and crystalloid solution. Laparotomy was performed initially in 11 patients; seven patients had sudden cardiovascular collapse as the abdominal wall tamponade was released and four patients remained hypotensive. With thoracotomy and thoracic aortic occlusion six of the 11 patients were resuscitated and had their injuries repaired. Thoracotomy and thoracic aortic occlusion were performed before laparotomy in 29 patients: seven patients remained hypotensive and expired; blood pressure was promptly restored in 22 patients and 11 of them survived the operative procedure. Left thoracotomy and thoracic aortic occlusion, before laparotomy, is offered as an alternative approach in patients with refractory hypotension and tense, abdominal distention. This technique aids in rapid restoration of vital signs, insures continued perfusion of the brain and myocardium, provides proximal arterial control, and prevents sudden cardiac arrest as the abdominal wall tamponade is released.
