[A comparison of ultrafast computed tomography, magnetic resonance angiography and selective angiography for the detection of coronary bypass patency].

Purpose: Validation of ultrafast-CT and MR-angiography (MRA) in comparison with angiography for detection of early postsurgical arterial and venous coronary artery bypass graft (CABG) patency.

Methods: 21 patients with a total of 55 CABG (34 venous and 21 arterial) were studied with angiography, ultrafast-CT (EBT), and MRA.

Results: With EBT, patency of 43/45 angiographically patent CABG could be correctly assessed (sensitivity: 96%).

[The value of ultrafast computerized tomography in detection of the patency of coronary bypasses].

Bypass graft patency with ultrafast computed tomography (= Electron Beam Tomography, EBT) was examined in 72 bypass grafts (47 saphenous veins, 25 internal mammary arteries) in 30 patients and compared with coronary angiography. Angiography was performed a mean of 4.4 +/- 3.

[2 cases of brief asystole following premedication--a possible connection with Thalamonal?].

Two cases of cardiac arrest about 30 min after intramuscular administration of premedication are analyzed. The patients were two young men without serious diseases in the history. The premedication consisted of Thalamonal (Innovar) and atropine.
