The canine middle cerebral artery (MCA) was embolized with a pliable cylinder 8 mm long by 1.6 mm in diameter via the internal carotid artery. Both control and experimental embolectomies were performed 6 hours following embolization. The experimental animals were treated with low molecular weight dextran (LMD). In the control animals, the average volume of infarction in the brain was 1.45 cm.3 ...

Acute thrombo-embolic occlusions of the subclavian artery account for less than 1% of all acute arterial occlusions of the extremities. One such case is presented and the management discussed with special reference to the technique of embolectomy and the treatment of the reperfusion syndrome with either fasciotomy or mannitol. The question of anticoagulation is also examined.

The following is an account of a 58-year-old lady who presented to our institution with two episodes of acute limb ischemia: one upper, which required embolectomy; and one lower, which required a below knee amputation. We subsequently performed transesophageal echocardiography (TOE), which revealed very large mobile echogenic masses adherent to the wall of her aortic arch, described below.

Massive pulmonary embolism associated with total cardiovascular collapse occurred during the surgical repair of a ruptured abdominal aortic aneurysm with an aortocaval fistula. Pulmonary artery pressure monitoring permitted immediate diagnosis whereas central venous pressures did not reflect the obstruction to right ventricular outflow. Pulmonary embolectomy without cardiopulmonary bypass was p...
