The paper is a unique pathological description of a bilateral, symmetric, anterior, temporal ischemic optic neuropathy with the morphological characteristics of cavernous optic atrophy initially described by Schnabel in glaucomatous eyes. The 80-year-old woman had suffered from cardiac insufficiency and diabetes mellitus for many years. She died from sepsis and circulatory collapse due to ischemic colitis, intestinal perforation, and peritonitis. There was widespread arteriosclerosis but no evidence of giant-cell arteritis. Cell loss was demonstrated in both retinas, the chiasm, and in the central lateral geniculate body. These represent a retrograde, descending and ascending optic atrophy, with transsynaptic degeneration in the LGB. A small craniopharyngioma was found by chance in the infundibulum. Neither clinically nor morphologically were there any signs of glaucoma.

Three cases of hypotension are described that followed rapid evacuation of persistent unilateral pneumothorax. Common features included the presence of a pneumothorax for approximately one week before treatment commenced and profuse unilateral reexpansion edema, a rising hematocrit reading, hypotension, and anuria after evacuation of the pneumothorax in spite of a relatively normal pulmonary capillary wedge pressure. In one case, cardiac output was measured and found to be low (1.54 and 1.65 L/min/sq m), with a pulmonary capillary wedge pressure of 10 to 14 mm Hg. Death due to cardiovascular collapse occurred in one patient; ischemic colitis, acute renal failure, disseminated intravascular coagulation, and ischemic necrosis of both humeral heads occurred in another. The cases presented and the literature reviewed suggest that cardiovascular compromise was the end result of the combined effects of intravascular volume depletion and myocardial depression.

We describe five patients with complications following amphetamine overdose. Two of the patients died: one with disseminated intravascular coagulation and circulatory collapse, one with severe rhabdomyolysis and ischemic colitis. Among the other three cases, one developed acute psychosis, hyperthermia and rhabdomyolysis, one developed acute respiratory distress syndrome and one pericarditis. The effects of amphetamine are discussed along with the diagnosis and treatment of patients with such poisoning.

Thoracic endovascular aortic repair (TEVAR) can be complicated by graft collapse, endoleaks, and stent migration. The incidence of these complications and other outcomes is poorly understood in young trauma victims who receive endovascular aortic repair of blunt thoracic aortic injury (BTAI). A 29-year-old pedestrian was struck by a vehicle resulting in polytrauma including BTAI with transection distal to the left subclavian artery origin. The patient underwent successful TEVAR. Nine months later, the patient developed transient paresthesia below the waist that progressed to bilateral lower extremity paralysis and malperfusion syndrome below the diaphragm including nonpalpable pulses in the lower extremities, acute renal failure, and ischemic colitis. Imaging demonstrated near occlusive thrombosis of the distal end of the thoracic endograft. An emergent axillobifemoral bypass resolved the organ malperfusion and acute limb ischemia. Patients who have undergone TEVAR for BTAI may develop asymptomatic or symptomatic intragraft thrombosis. In patients presenting with malperfusion syndrome below the diaphragm, extra-anatomic bypass can expeditiously resolve symptoms until definitive treatment can be performed. Oversizing of thoracic stents in trauma patient may lead to intragraft thrombosis.
