A 56-year-old man with a failing aortic prothesis involving aortic insufficiency and with a dissecting aneurysm of the aortic cross, developed a unilateral pulmonary edema. Although radiological literature often describes this phenomenon, it is sometimes mis-diagnosed in medical clinics. The literature available is briefly reviewed and we discuss the most probable mechanisms causing unilateral presentation of pulmonary edema. The effect of gravity or posture, with or without variations of pulmonary venous pressure, disturbances of the neurogenic control of capillary size and permeability, pleural pathologies and impairment of vascularization of one lung are hypotheses put forward to explain the unilaterality of the distribution.

We described a case of cerebellar hemorrhage after trapping of a vertebral artery dissecting aneurysm. A forty-eight-year-old man had suffered from severe headache, vomiting and disturbance of consciousness. He was transferred to our hospital in an ambulance. Emergency CT scan showed subarachnoid hemorrhage in the posterior fossa predominantly, intraventricular hemorrhage and hydrocephalus change. Chest X-ray showed radiological evidence of pulmonary edema. The initial blood-gas determinations demonstrated a marked reduction in PaO2 and increased PaCO2. Five days after admission, the patient's condition was improving. Cerebral angiography was performed using the Seldinger method. It revealed a right vertebral artery dissecting aneurysm just distal to the posterior inferior cerebellar artery. We performed an operation to trap the VA dissecting aneurysm. Blood pressure was well controlled under 140 mmHg during the operation and he recovered from anesthesia completely. On the day after the operation, suddenly the patient's consciousness began to deteriorate. Emergency CT scan was performed and it showed SAH, cerebellar hemorrhage and diffuse swelling of the cerebellum on the same side as the operation. We suspected rebleeding of the aneurysm due to a clip's having slipped. Reoperation was performed, but the clip was not displaced and there were no definite bleeding vessels on the operative field. Consequently only external decompression and resection of the right cerebellum were performed. We discuss pathogenesis of the occurrence of hemorrhage in this particular case after trapping. We also review the relevant literature.

A 48-year-old woman with aortitis syndrome underwent clipping of dissecting aneurysm of the left posterior inferior cerebellar artery following subarachnoid hemorrhage. Preoperative echocardiography demonstrated moderate aortic regurgitation and pulmonary hypertension. Intravenous infusion (1900 ml.day-1) was performed to avoid cerebral vasospasm, but the patient developed lung edema. She received delayed surgical treatment after the improvement of lung symptoms. Anesthesia was induced with fentanyl (0.1 mg), propofol (90 mg) and vecuronium (6 mg). Radial arterial flow was judged to be insufficient for cannulation, and a cannulation was therefore performed on the dorsal pedis artery. During induction of anesthesia, there was a significant decrease in the arterial pressure, that required a total of 32 mg of intravenous ephedrine. Following tracheal intubation, a central venous catheter was inserted and dopamine was continuously administered. The patient was positioned in the park bench position. We thought that the placement of the introducer for Swan-Ganz catheter was difficult under the position and Swan-Ganz catheter was not inserted. Anesthesia was maintained with sevoflurane, air, and oxygen. We continuously monitored the central venous pressure as an indicator of fluid balance. In this case, we monitored dorsal pedis arterial pressure directly, which might not be sufficiently reliable to predict the decrease in cerebral blood flow.

We describe a 48(correction of 44) year-old woman, who presents a non-cardiogenic pulmonary edema caused by non-ionic radiographic contrast medium. She suffered from subarachnoid hemorrhage due to dissecting aneurysm of right vertebral artery. Cerebral angiography followed by coil embolization for the aneurysm was performed. During the interventional procedure, saturation of blood oxygen suddenly declined and chest X-ray photography obviously revealed pulmonary edema. At first we dealt with it as neurogenic phenomenon but subsequently interpreted it to non-cardiogenic pulmonary edema induced by radiographic contrast medium, since intra-arterial injection of contrast medium at follow-up angiography led the symptoms into more fulminant status. Intensive care including endotracheal intubation and continuous positive airway pressure ventilation consequently achieved complete remission and the patient discharged without any sequelae. Although low osmolar, non-ionic contrast medium has been regarded as relatively safe, severe reaction such as dyspnea, hypotension and cardiac arrest could emerge at certain intervals. We must perceive the adverse effects of it because the usage of contrast medium will dramatically increase with development of diagnostic radiographical methodology and interventional neurosurgery.
