The adverse effects following lumbar myelography and ventriculography with meglumine iothalamate (Conray Meglumin), meglumine iocarmate (Dimer-X, Bis-Conray) and metrizamide (Amipaque), and after thoracic and cervical myelography and cisternography with metrizamide are reviewed. In addition to the published material information given to Nyegaard & Co. from several hospitals participating in clinical trials with metrizamide is also reported. The frequency of minor adverse effects (headache, nausea, vomiting) seems to be about the same with all the three water-soluble contrast media. Convulsions, either localized to the lower part of the body or generalized, may be a problem with meglumine iothalamate and meglumine iocarmate, while the epileptogenic effect is markedly lower with metrizamide. With a technique directed towards preventing contrast medium of high concentration from passing intracranially, the frequency of serious adverse effects may be kept at a very low level. Late adverse effects (adhesive arachnoiditis) occurring after all other water-soluble contrast media are a very minor problem after metrizamide. Serious complications have not been recorded following ventriculography and cisternography with metrizamide. Metrizamide is considered to be the water-soluble contrast medium best suited for use in the subarachnoid space and cerebral ventricles.

Giant aneurysm of the posterior cerebral artery was very rare. The authors could seek only 6 cases in published literature. We experienced one case of the giant aneurysm at the posterior cerebral artery. The case was 25 years old female. She occasionaly complained of headache and nausea for 4 years before administration. Cerebral angiogram revealed a giant aneurysm of the right posterior cerebral artery with slightly dilated ventricle. CT scan revealed a ring shape high density area and its high density area enhanced by Conray infusion. A clipping of posterior cerebral artery at the just proximal point of the aneurysmal neck was done, because adhesion of the aneurysm to the brain stem was very tight and the aneurysmal neck was very broad. After the operation, giant aneurysm was not seen on both angiogram and CT scan. Patient did not complain of headache any more and any defect of the visual field.

Meglumin-Iodrinat has been synthesized as the contrasting part of Myelografin by Schering AG. and tested for lumbar Myelography in animal experiments. The excellent neural and general compatibility justified a first clinical trial. 200 patients were examined, 100 each with following upright or lying down positions. There were no local symptoms, no signs of spinal or cerebral irritation. This is seen to be the main advantage compared with drugs used so far. Intensity of contrast corresponded with that of Conray 60 and Dimer X. The most common complaints like headache and nausea were interpreted as CSF hypotension and can be clearly reduced by lying down. Also the concentration of the contrastmedium diminishes more rapidly with the patient lying down.

A case of occipital tumor simulating sinus pericranii was reported. The patient was a 4-year-old girl who suffered from headache and nausea following head injury on midoccipital tumor, but had no remarkable neurological deficit. Her occipital tumor was soft, compressible redish and cyst-like without bruit. Conray cystography of this tumor showed superior sagittal sinus like shadow (Fig. 4). Total removal of the tumor associated with epidural hematoma was performed. Histologically this tumor was confirmed as eosinophilic granuloma. Pathogenesis of this case is following, since patient's tumor was blowed, intratumor-bleeding occurred cosequently and the bleeding flowed into epidural space. So the tumor simulated sinus pericranii (Fig. 5.).

Forty consecutive patients with coronary artery disease undergoing left ventricular angiography took part in a randomised double blind trial comparing a conventional contrast medium sodium meglumine iothalamate (Cardio-Conray) with the low osmolar agent iopamidol. Iopamidol produced a smaller rise in heart rate and a smaller fall in left ventricular systolic pressure, but the changes in left ventricular and diastolic pressure and maximum rate of change of pressure (dP/dt max) were not different. The numbers of extrasystoles per minute for five minutes after ventriculography were similar in both groups except for the first 15 seconds, when the number of extrasystoles was increased in the iopamidol group. The frequency and magnitude of symptoms (heat, angina, headache, nausea) were significantly different in two groups. Iopamidol caused less haemodynamic disturbance than Cardio-Conray, although the improvement is small and offers no advantage in reducing symptoms or extrasystoles.

We compared Hexabrix 320 (580 mOsm kg-1) with Conray 420 (2500 mOsm kg-1) for left ventriculography using a prospective randomised double-blind protocol. One hundred consecutive patients with suspected coronary disease were assigned to Hexabrix (52) or Conray (48) for left ventriculography (dose 10 ml m-2 BSA; flow rate 12 ml s-1). Thirteen patients found Hexabrix unpleasant compared with 24 receiving Conray; overall the feelings of warmth and discomfort were less with Hexabrix than Conray (p less than 0.01 and p less than 0.02 respectively). The incidence of nausea, vomiting, and hypersensitivity was similar. Angiographic quality was better with Conray than with Hexabrix (p less than 0.05). Average changes in heart rate and systolic pressure were similar, though there was greater variation in systolic pressure change after Conray (p less than 0.025). End diastolic pressure increased more after Conray than after Hexabrix (p less than 0.05). These slight advantages of Hexabrix over Conray may be valuable in patients requiring multiple angiograms or in those with impaired cardiac function, but do not justify its use for routine angiography.
