May-Thurner syndrome.

Three patients with long standing edema of the left leg were examined, and venography and hemodynamic studies were performed. All three patients had a "spur" (May-Thurner syndrome) of the left common iliac vein at the level of the crossover position of the right common iliac artery. Surgical exploration in two of these patients verified marked hypertrophy of the intima of the left common iliac vein that caused partial obstruction. Surgical repair resulted in great improvement. Anatomic findings at venography are characteristic of this syndrome. Hemodynamic pressure measurements are of ancillary help in confirming the diagnosis.

Intralobar pulmonary sequestration: value of aortography and pulmonary arteriography.

Twelve patients with plain roentgenographic findings of intralobar pulmonary sequestration were evaluated with aortography and, in most instances, pulmonary arteriography. Correlative criteria from aortography and pulmonary arteriography permit a precise diagnosis to be made. Pulmonary infections must be differentiated from intralobar pulmonary sequestration because treatment for the latter should be surgical.

Leiomyosarcoma of the inferior vena cava: angiographic and computed tomography findings. Report of two cases and review of imaging criteria.

Leiomyosarcoma, a highly malignant tumor of the inferior vena cava, is rare. Only 55 cases have been reported in the world literature, and of these only 18 were evaluated with a special vascular procedure, either arteriography or inferior vena cavography. In two cases of leiomyosarcoma of the inferior vena cava, we performed arteriography and inferior vena cavography. In one, computed tomographic studies were also carried out. Cavography showed a lobulated filling defect in one case and complete caval occlusion with collateral circulation in the other. In the one case in which it was performed, computed tomography clearly demonstrated the tumor's size and its relationship to surrounding organs. Arteriographic studies, however, allowed only an indistinct delineation of the extent of tumor growth in one case. Venography followed by computed tomography should permit adequate assessment of most leiomyosarcomas of the inferior vena cava, with arteriography reserved for tumors involving the upper cava in which hepatic involvement must be evaluated.

Pulmonary hemorrhage. Vascular evaluation and interventional therapy.

Twenty-five cases of massive pulmonary hemorrhage were evaluated by arteriography. Either pulmonary or selective bronchial arteriography or both were performed to confirm or corroborate the clinical diagnosis. In 16 patients, gelfoam embolization of the bronchial artery was effective in causing immediate cessation of the hemorrhage. Only two of the 16 patients had recurrent pulmonary hemorrhage, both of whom had invasive central primary carcinoma of the lung.

Arteriography after carotid endarterectomy.

Of 55 patients undergoing carotid endarterectomy, 16 had abnormal postoperative angiograms by accepted literature criteria. Five of the 16 were symptomatic. The other 11 were neurologically stable or improved from their preoperative condition. None of the 16 patients underwent reoperation. Of those 11 who had abnormal postoperative angiograms but a good clinical result, four had a second postoperative angiogram some months later that demonstrated marked improvement in the appearance of the endarterectomy site. Patients undergoing carotid endarterectomy should not be subjected to routine postoperative angiography without clinical indications nor should they undergo reoperation on the basis of angiographic findings alone without consideration of their clinical status.

Emergency arteriography in extremity trauma: assessment of indications.

Two hundred and four cases of extremity trauma were evaluated. Arteriography was performed in 70 patients for one or a combination of the following indications: absent or diminished pulse, proximity to a major vessel, enlarging or significant hematoma, neurologic deficit, fracture or dislocation, or systemic hypotension. Of the 70 patients, 37 (53%) demonstrated positive arteriographic findings; the most common was arterial occlusion. Patients with an absent or diminished pulse, the most reliable indicator of arterial injury, should have immediate arteriography. Patients who have strong and equal peripheral pulses and are clinically stable should be observed and undergo elective arteriography. Three patients with intimal injuries had intact pulses, but no pattern of indications was helpful in identifying these injuries. A combination of indications is indicative of more serious injury and more likely to produce a positive arteriographic study.

Carotid--cavernous fistula--iatrogenic carotid--cavernous fistula due to thrombectomy with a Fogarty catheter.

Removal of thrombus from a totally occluded internal carotid artery with a patent siphon by means of a balloon-tipped Fogarty catheter has been an acceptable technique. There have, however, been five reported cases of carotid-cavernous fistula following this procedure (Barker et al., 1968; Davie and Richardson, 1967; Motarjeme and Keifer, 1973; Newton and Potts, 1974). The purpose of this report is to add a sixth case to the literature and to suggest that this surgical method be abandoned.

Iliocaval thrombi in pulmonary thromboembolic disease.

Rational management of patients with pulmonary thromboembolic disease should include assessment of the risk of additional emboli. Other authors have shown that the possibility of fatal pulmonary embolism is higher when the iliofemoral system contains thrombus, and it is recommended that vena caval interruption rather than simple anticoagulation is indicated. Additional factors governing the therapeutic choice should include the magnitude of the original embolic occlusion as well as the presence of antecedent cardiopulmonary disease. In these instances large thrombi in the iliocaval system should be regarded as potentially life threatening. A sequence of angiography beginning with right iliac and vena caval opacification, proceeding to pulmonary arteriography, and terminating with retrograde left iliac vein study provided information needed to individualize the therapeutic approach. Several case reports illustrate the spectrum of abnormalities and their therapeutic implications.

The neuroradiologic evaluation of "optic neuritis".

Optic neuritis, even when clinically typical, cannot be diagnosed with certainty because mass lesions compressing the anterior visual pathways may mimic it. The radiologist is in a position to assist in identifying such lesions or in ruling them out and thus preventing surgical exploration. While every patient in whom the diagnosis of optic neuritis is entertained should have plain roentgenograms of skull, orbits and optic canals, we have developed a schema for detailed neuroradiologic investigation based on clinical and plain roentgenographic findings. A classification of such lesions by location is illustrated.
