Thirteen cases of cerebral aneurysms submitted to endovascular treatment using Guglielmi detachable coils (GDC) are described. Control MRI-angiography 3D TOF was performed three and six months later. In order to spare patients the discomfort and risks related to repeated trauma and iodate contrast injection, we examined the possibility of an alternative non-invasive diagnostic method. For this purpose, the digital subtraction angiograms performed three and six months after embolisation were compared with the MR-angiograms obtained in the same period, all using the same tomograph at middle field intensity (0.5T). We discuss the outcome of this comparison and the limits of the MR-angiography method in the follow-up of aneurysms submitted to endovascular treatment.

Acute angiographical changes for preventing acute rebleeding on GDC treated cerebral aneurysms were evaluated. From December 2000 to November 2002, 48 total aneurysms in 44 consecutive patients with acute SAH. Acute angiographical evaluations were carried out in 46 aneurysms, including 42 ruptured and 4 unruptured aneurysms. Two cases were excluded because of poor medical condition. In this series, there were no rebleeding cases in acute stage. In the initial embolization for the 46 aneurysms, CO was achieved in eight aneurysms, NR in 15 aneurysms and BF in 23 aneurysms. Acute angiographical observations showed progressive thrombosis in 17 aneurysms (37%). No changes were observed in remaining 29. No recanalization was observed in this series. Only one case of BF, inside the aneurysm bleb was still observed during follow up. Additional embolization was carried out. Progressive thrombosis was frequently observed in GDC treated cerebral aneurysms during acute stage. This angiographical finding seems to show prevention of rebleeding, which is considered important for the management of GDC treatment in acutely ruptured cerebral aneurysm.

A Current

A follow-up of the embolized cerebral aneurysm with Guglielmi Detachable Coils (GDC) were performed mainly using craniograms and digital subtraction angiograms (DSA) so far. Recently, several authors have reported about efficacy of the time of flight (TOF) magnetic resonance angiogram (MRA) as a follow-up for the embolized cerebral aneurysms. In our institution, 3-D reconstructed TOF MRAs have been performed as a follow-up of the embolized cerebral aneurysms. We examined efficacy of 3-D reconstructed TOF MRA. 3-D TOF MRA was performed for a follow-up of the embolized cerebral aneurysms at our outpatient clinic in 35 patients. Morphological examination of the 3-D images between 3-D TOF MRA and 3-D DSA was performed. Almost similar images of 3-D MRA were obtained after 3-D reconstruction as compared with those of 3-D DSA. In three cases, recanalization was suspected in the 3-D TOF MRA. And recanalization was confirmed in the 3-D DSA actually. A quality of 3-D TOF MRA for a diagnosis of recanalization was good and practical. However, in two cases, arteries were partially disappeared in the 3-D TOF MRA. These were the artifact due to coil mass and this is a current limitation of 3-D TOF MRA. The images of 3-D TOF MRA that were reconstructed in the 3-D workstation were very similar to those of 3-D DSA. 3-D reconstructed TOF MRA was very useful for a less-invasive diagnosis of a recanalization of the embolized cerebral aneurysms.

Effect Time

MR angiography represents a useful non-invasive tool to explore cerebral vessels. Two techniques of acquisition are generally used, based respectively on the “inflow effect” (time-of-flight technique) and on motion-related phase changes (phase contrast technique). The main advantage of MR angiography over conventional digital subtraction angiography is the lack of invasiveness; because of this it requires less technical training and may be easily repeated for follow-up purposes. On the other hand, the main disadvantages of this technique are limited spatial resolution, incomplete fresh blood saturation and difficulties in monitoring critical patients. In our experience, MRA is routinely used in the screening of patients at risk for cerebral aneurysms, and in the follow-up of patients submitted to endovascular treatment.

✓ The authors report their experience using electrolytically detachable coils for the treatment of residual cerebral aneurysms following incomplete surgical clipping. Eight patients were treated for six anterior and two posterior circulation aneurysm remnants. All patients were referred for endovascular treatment by experienced cerebrovascular neurosurgeons at the authors' institution. Patients underwent follow-up angiography immediately after endovascular treatment. In seven of the eight patients, additional follow-up angiographic studies were obtained at periods ranging from 7 weeks to 2 years posttreatment. The latest follow-up angiograms demonstrated that six of the eight aneurysm remnants were 100% occluded, with near-complete occlusion of the other two aneurysm remnants. There was no permanent neurological or non-neurological morbidity or mortality associated with the treatment. There was no incidence of aneurysm hemorrhage during or after treatment. Endovascular treatment of cerebral aneurysm remnants following prior surgical clipping can be accomplished with acceptable morbidity and mortality rates. Endovascular coil occlusion can play an important adjunctive role in the treatment of those aneurysms that have been incompletely obliterated by surgical clipping.
