Neurological complications of coronary arteriography.

The authors report a 46 year-old female who was submitted to a right femoral artery coronary arteriography. During the procedure she presented an upward, downward and convergence gaze paresis; an upbeating nystagmus. A NMRI showed a change in T-2 weighted signal of the left paramedian mesencephalic region. A diagnosis of stroke was made and dextran 40 was prescribed. Vertical gaze paresis progressively disappeared. Convergence paresis and nystagmus improved partially only. The possible pathophysiological basis underlying this clinical picture are: catheter-induced dislodgement of an atheromatous plaque; small thrombi formation and release from the catheter tip; catheter-induced vascular lesion with subsequent thromboembolism or dissection of the intima; cardiac arrhythmia; catheter-induced or contrast medium-induced arterial spasm; a combination of two or more of these.

Direct myocardial revascularization in young patients: analysis of 100 consecutive cases without operative mortality.

The authors studied a series of 100 patients submitted to direct myocardial revascularization before 40 years of age. One hundred and seventy-three saphenous vein by-passes and 4 mammary artery left descending coronary artery anastomoses were performed. There was no operative mortality and the late mortality was 2%. The period of postoperative clinical evaluation of the patients varied from 12 to 60 months (mean 32.0 months).

Anomalous origin of the left coronary artery from the pulmonary artery. Surgical repair of an unusual form.

The authors present a case of a 24-year-old woman with anomalous left coronary artery originating from the pulmonary artery. Surgical correction was performed by the direct transposition of the anomalous left coronary artery from the pulmonary artery to the ascending aorta, without interposed graft. Pre- and postoperative evaluations, including angiograms and cycloergometer stress test are presented. The advantages of this technique are discussed, emphasizing the creation of a two-coronary system without the use of prosthetic, arterial or venous grafts. In the present case the left coronary artery originated from the right posterior sinus of the pulmonary artery. The patient is doing well 23 months after operation.

Course of the post-catheterization pulseless arm.

With the purpose of determining the course of the non-operated post-catheterization brachial artery thrombosis, 45 patients in this condition were followed during a one month period of survey. A gradual increase in Doppler-derived pressure index of the ischemic arm was observed. This index averaged 0.51 on the day of occlusion, increased to an average of 0.66 in the immediate following day and on the 30th day averaged 0.82. All but 10 patients were asymptomatic after 30 days, although a similar increase in pressure index was observed among these patients, being thus indistinguishable from the whole group. Since it was not possible to predict in which patients symptoms of arm ischemia would remain present, it seems advisable to consider surgical restoration of flow in all cases of brachial artery thrombosis after cardiac catheterization.
