Stenosis of the deep femoral artery: an evaluation of the accuracy of single-plane, anteroposterior arteriograms.

Pre-operative evaluation of the deep femoral artery is important in determining surgical treatment of aortofemoral disease. We reviewed 16 years' experience in bilateral aorto-femoral by-pass grafting and found that 63.2% of stenoses of the deep femoral arteries seen at surgery had been missed on conventional antero-posterior arteriograms. These findings demonstrate the inadequacy of a single, antero-posterior projection and the need for supplementary views in assessing lesions of the deep femoral artery.

The complication rate of catheter angiography by direct puncture through aorto-femoral bypass grafts.

A search of the literature revealed no documentation of the complication rate associated with percutaneous catheterization of aorto-femoral bypass grafts in the arteriographic evaluation of graft patency. The authors compared the complication rates of 29 consecutive arteriograms performed through grafts (Group I) with 40 arteriograms performed on non patients (Group II). Neither group had any significant complications, indicating the safety of percutaneous catheterization of the graft site.

RAPORT radiology system: results of clinical trials.

RAPORTTM, an automated radiology management and reporting system is currently operational in more than 25 hospital departments of varying sizes and types. Data have been gathered from 19 installations in operation for 6 months or longer and four systems which failed. Findings were as follows: 1. Mark sense forms were used in 71% of cases (29% dictation) and for an average of 70% of all pathologic material. 2. Report turnaround time ranged from 0.1 to 6 hr (average 2.5 hr) depending on departmental priorties and organization. 3. Rejection of the system was based upon inadequate documentation of needs prior to installation, poor preparation of staff members, and underestimation of the impact on computer systems on existing organizations. 4. System downtime averaged 2.5 hr per month. 5. The ratio of pathologic to normal reports did not vary significantly among university, government, and private hospitals. 6. RAPORT can no longer be considered an experimental system. Properly managed, it is an effective administrative tool which can significantly improve departmental service.

Arteriographic evaluation of the femoral bifurcation value of the ipsilateral anterior oblique projection.

Accurate preoperative evaluation of the proximal deep femoral artery is critical in proper surgical management of aortofemoral ischemic disease. A review of 116 femoral arteriograms demonstrated significant improvement in visualization of the femoral bifurcation and detection of proximal stenosis of the deep femoral artery when the ipsilateral anterior oblique projection was obtained in addition to the conventional anteroposterior projection.

Cerebellar glioblastoma multiforme in an adult.

One of the few well documented cases of cerebellar glioblastoma multiforme in an adult is reported. In addition, to our knowledge, it is the first reported case in which the angiographic, pneumoencephalographic, nuclear scan and CAT data have been correlated. In this case the CAT scan proved the most sensitive in the demonstration of tumor.

Selective cerebral angiography through the axillary artery.

The femoral artery approach to cerebral angiography has become well accepted. Some patients, however, are not candidates for femoral catheterization because of severe arteriosclerosis. One hundred cerebral angiograms were performed in 88 severely arteriosclerotic patients, using No. 5 French polyethylene catheters and the axillary approach. The technique, degree of success, patient population, and their complications are described. This approach allows selective vertebral and internal carotid artery injections. Only one serious complication occurred, thrombosis of the axillary artery. Because of the time saved, this technique is often preferable to the femoral approach in severely arteriosclerotic patients.

Computer analysis of factors associated with thrombus formation observed on pullout angiograms. Preliminary communication.

A prospective study was instituted to determine both the incidence of postcatheterization arterial thrombus formation and the possibility of a statistically significant correlation between predetermined parameters and the incidence of arterial thrombosis. Pullout angiograms and 12 recorded variables from 176 procedures were studied. Postcatheterization arterial thrombus formation was demonstrated in 9 cases (5%). Statistical analysis by computer showed a statistically significant relationship between 4 factors and postcatheterization thrombosis, viz. catheter/artery ratio, age, catheter diameter, and number of puncture attempts. Total elapsed time of the procedure was not found to be a statistically significant variable. These variables are integrated into a postulate to explain the pathogenesis of postcatheterization thrombus formation seen on pullout angiograms.

Relationship of transient ischemic attacks and angiographically demonstrable lesions of carotid artery.

Eighty-eight percent of arteries in patients with amaurosis fugax or hemispheric transient ischemic attacks had angiographically demonstrable lesions at the carotid bifurcation. Eighty-one percent had stenoses or occlusions at the carotid bifurcation; 7 percent had ulcerative lesions without stenoses at this site. Forty-nine percent of arteries in these patients demonstrated ulcerative lesions with or without stenosis at the carotid bifurcation. There was no significant difference in the incidence or types of ulcerations between those patients with amaurosis fugax and those with hemispheric transient ischemic attacks. Eighty-eight percent of arteries examined in this series were amenable to surgical reconstruction. Amaurosis fugax and hemispheric transient ischemic attacks were of equal value in predicting the possibility of a surgically treatable lesion at the carotid bifurcation.
