✓ The authors review 22 consecutive cases of anterior communicating artery aneurysms treated by stereotaxic iron-acrylic occlusion. There was no mortality and no rebleeding in this series. The morbidity was low, and 16 of the 22 patients have returned to work. The patients whose aneurysms could be treated transsphenoidally enjoyed the best outcome.

✓ Two cases are presented in which clip occlusion of a third distal anterior cerebral artery segment occurred during treatment of anterior communicating artery aneurysms. Case histories, angiograms, operative descriptions, and postmortem findings are presented. The incidence of this anomalous vessel is reviewed. Preoperative and intraoperative vigilance in determining the presence of this anomaly prior to clip placement is emphasized.

✓ Results of surgical treatment of anterior communicating artery aneurysms, approached via bifrontal craniotomy, are reported in 110 cases. It was possible to preserve the olfactory tracts bilaterally or unilaterally in over 65% of these cases: 47% with bilateral preservation and 34% with unilateral preservation; 33% of the patients with bilateral olfactory tract damage reported subjectively normal olfaction. Objective examination of olfaction by an otolaryngologist showed that 84% of the patients reporting normal olfaction did indeed have normal olfaction, whereas 91% of these reporting no olfaction were anosmic.

✓ Analysis of the use of the clip-graft for intracranial aneurysms indicates that the clip-graft is chiefly applicable to internal carotid and anterior communicating artery aneurysms. The development of the right-angle clip holder has extended its use to anterior communicating artery aneurysms that project posteriorly or superiorly. The dangers of dissection in the septal region are discussed. With few exceptions, the clip-graft is not applicable to the vertebrobasilar system or middle cerebral artery trifurcation aneurysms, although it has been used for aneurysms arising from the trunk of the latter vessel.

✓ As an alternative to approaching anterior communicating artery (ACoA) aneurysms through the frontal fossa, either parasagittally or laterally (pterional, gyrus rectus approach), this report describes an approach to ACoA aneurysms through the temporal fossa. The main advantages of this temporal technique are that it requires less brain retraction, gives better surgical orientation, gains control of both A1 segments before disturbing the aneurysm, and involves minimal resection of brain tissue. This temporal approach has recently been used by the author in 20 consecutive operations for ACoA aneurysms in preference to the gyrus rectus approach.

✓ In 296 cases with a single aneurysm of the anterior communicating artery (ACoA), fenestration or the presence of more than two ACoA's was observed in 17 cases (5.7%), and abnormal vessels of ACoA origin, such as a median artery of the corpus callosum, were observed in 13 cases (4.4%). As more than one anomaly was found in some of these cases, anomalies of the ACoA were found in a total of 26 cases (8.8%). This occurrence rate was no higher than that observed in other cerebral aneurysm cases and in the control cases, which were reported previously. There was no significant increase of hypoplasia of the A1 portion if the ACoA aneurysm was complicated by other arterial anomalies.

Object. The routine use of intraoperative angiography as an aid in the surgical treatment of aneurysms is uncommon. The advantages of the ability to visualize residual aneurysm or unintended occlusion of parent vessels intraoperatively must be weighed against the complications associated with repeated angiography and prolonged vascular access. The authors reviewed the results of their routine use of intraoperative angiography to determine its safety and efficacy. Methods. Prospectively gathered data from all aneurysm cases treated surgically between January 1996 and June 2000 were reviewed. A total of 303 operations were performed in 284 patients with aneurysms; 24 patients also underwent postoperative angiography. Findings on intraoperative angiographic studies prompted reexploration and clip readjustment in 37 (11%) of the 337 aneurysms clipped. Angiography revealed parent vessel occlusion in 10 cases (3%), residual aneurysm in 22 cases (6.5%), and both residual lesion and parent vessel occlusion in five cases (1.5%). When compared with subsequent postoperative imaging, false-negative results were found on two intraoperative angiograms (8.3%) and a false-positive result was found on one (4.2%). Postoperative angiograms obtained in both false-negative cases revealed residual anterior communicating artery aneurysms. Both of these aneurysms also subsequently rebled, requiring reoperation. In the group that underwent intraoperative angiography, in 303 operations eight patients (2.6%) suffered complications, of which only one was neurological. Conclusions. In the surgical treatment of intracranial aneurysms, the use of routine intraoperative angiography is safe and helpful in a significant number of cases, although it does not replace careful intraoperative inspection of the surgical field.

✓ The intraoperative anatomical findings of the anterior communicating artery (ACoA) complex in 46 patients with anatomical variations were compared to those in an equal number of patients without variations in order to determine the visualization of the elements of the vascular complex. All patients underwent radical surgery for an ACoA aneurysm by one of three different surgical approaches: transsylvian, anterior interhemispheric, or basal interhemispheric. Visualization of the vascular elements was similar in patients with or without anatomical variations. The differences observed were dependent on the surgical approach selected and on the projection of the aneurysm. It was found that, even when the intraoperative anatomical field and the number of vascular elements visualized are different from those obtained in autopsy studies, the vascular microanatomical characteristics can be confirmed with each surgical approach to the extent necessary to ensure safe clipping of aneurysms in patients both with and without anatomical variations.

Object. The exceptional pediatric aneurysm can be distinguished from its adult counterpart by its location and size; however patient outcomes remain difficult to evaluate based on the published literature. Methods. Twenty-two children, all consecutively treated in three neurosurgery departments, were included in this study. Each patient's preoperative status was determined according to the Hunt and Hess classification. Routine computerized tomography scanning and angiography were performed in all children on the 10th postoperative day. Each patient's clinical status was evaluated 2 to 10 years postoperatively by applying the Glasgow Outcome Scale (GOS). Twenty-one children presented with a subarachnoid hemorrhage (SAH) and one child harbored an asymptomatic giant aneurysm. Thirteen patients were in good preoperative grade (Hunt and Hess Grades I to III) and eight in poor preoperative grade (Hunt and Hess Grade IV or V). The symptomatic aneurysms were located on the internal carotid artery bifurcation (36.4%); middle cerebral artery (36.4%), half of which were found on the distal portion; anterior communicating artery (18.2%); and within the vertebrobasilar system (9.1%). A giant aneurysm was observed in 14% of patients. Overall outcome was favorable (GOS Score 5) in 14 children (63.6%) and death occurred in five (22.7%). Causes of unfavorable outcome included the initial SAH in four children, a complication in procedure in three children, and edema in one child. Conclusions. Pediatric aneurysms have a specific distribution unlike that of aneurysms in the adult population. The incidence of giant aneurysms and outcomes were similar to those in the adult population. The major cause of poor outcome was the initial SAH, in particular, the high proportion of rebleeding possibly due to a delay in diagnosis.
