Objective: The "Sheep technique" is a special technique for navigating a balloon catheter that is difficult to navigate because of the steep angle of the branching vessel.<br>Case presentation: We treated two patients having intracranial aneurysms by endovascular therapy with the sheep technique. In both cases, initial balloon catheter navigation failed because the branch near the aneurysm was steep. With the aid of the sheep technique, the balloon catheter was successfully delivered into the target vessel. Coil embolization was then performed using a balloon remodeling technique.<br>Conclusion: The sheep technique is effective when balloon catheter delivery is difficult because the branch near the aneurysm is steep.

The aim of this study was to analyze the effect of endovascular treatment of basilar (BA) tip aneurysms. The authors performed a retrospective analysis of 79 aneurysms of the BA tip that had been treated using endovascular coil embolization for the last 11 years. Fifty-six patients were women, and 23 were men. The average age of the patients was 63.7 years (range, 35-83 year). The average maximum diameter of the aneurysms was 8.0 mm (range, 2-30 mm). Forty-seven patients (60%) presented with acute subarachnoid hemorrhage (SAH), 1 patient (1%) had an unruptured aneurysm with mass effect, and 31 patients (39%) had incidental aneurysms. Immediate anatomic outcomes demonstrated complete occlusion (CO) in 53 aneurysms (67%), residual neck (RN) in 22 aneurysms (28%), and residual aneurysm (RA) in 4 aneurysms (5%). One patient died from rebleeding 6 hours after the embolization. Another patient suffered from rebleeding 6 years after the initial embolization, and was successfully treated with re-embolization. Four patients suffered from asymptomatic P1 occlusion. No symptomatic complication was observed in the unruptured group. Retreatment was performed in 5 patients, including 4 broad-neck large ruptured aneurysms and 1 giant thrombosed aneurysm. Angiographic and clinical results have been improving in recent cases in this study. Technical advances such as highly compliant balloon remodeling microcatheter and 3D-reconstructed digital angiography contributed to this improvement. Our results indicate that endovascular treatment of BA tip aneurysm is safe and effective. The long-term stability after coil embolization is still a matter of concern. Further improvement is expected.

[A case of cavernous sinus dural arteriovenous fistula presenting with intracranial hemorrhage].

No shinkei geka. Neurological surgery 39 ( 7 ) 687 - 92 2011.7

Language：Japanese Publishing type：Research paper (scientific journal)

Intracranial cavernous sinus dural arteriovenous fistula (CS-dAVF) rarely causes intracranial hemorrhage. We report a case of CS-dAVF presenting with intracranial hemorrhage. A 62-year-old man presented tonic clonic convulsion with consciousness disturbance and was transferred to our hospital. CT scan revealed subarachnoid hemorrhage and right frontal subcortical hemorrhage. Angiography revealed right CS-dAVF which drained only into the vein of the right sylvian fissure. Transvenous embolization was performed using detachable coils. After embolization, CS-dAVF had completely disappeared and the patient was discharged without any symptom. We summarized the fourteen reported cases, including ours, of CS-dAVF with intracranial hemorrhage. All of them had retrograde drainage through cerebral veins.

Unusual cisternal coil migration in the follow-up period after aneurysm perforation during endovascular coiling.

Neurologia medico-chirurgica 51 ( 5 ) 365 - 7 2011

Language：English Publishing type：Research paper (scientific journal)

A 61-year-old woman suffered cisternal coil migration in the follow-up period after endovascular coil embolization for a ruptured cerebral aneurysm. She presented with sudden onset of headache. Computed tomography demonstrated diffuse subarachnoid hemorrhage, and cerebral angiography disclosed a left anterior choroidal artery aneurysm. The aneurysm was treated by endovascular embolization with Guglielmi detachable coils. During the embolization procedure, the microcatheter perforated the aneurysm. For direct closure of the perforation site with coils, the microcatheter was withdrawn and coils were deployed partially in the subarachnoid space and partially in the aneurysm sac. The coil mass was spread in the subarachnoid space around the aneurysm immediately after embolization. The patient was discharged with no neurological deficit. Three months later, follow-up radiography demonstrated obvious reduction in the size and compaction of the coil mass. Magnetic resonance angiography and digital subtraction angiography demonstrated stable occlusion of the aneurysm. The coil mass probably spread in the cistern around the aneurysm and was compacted by the shape memory of the coils and pulsation of the brain and vessels, as the subarachnoid clots around the aneurysm had disappeared. This case suggests that cisternal coil migration should be considered in the follow up of intracranial aneurysm treated with detachable coils.

[Transient homonymous hemianopsia due to thrombosis of the confluence of sinuses after occipital transtentorial removal of pineal region tumor].

Toshinari Meguro, Tatsuya Sasaki, Jun Haruma, Tomoyuki Tanabe, Kenichiro Muraoka, Kinya Terada, Nobuyuki Hirotsune, Shigeki Nishino

No shinkei geka. Neurological surgery 38 ( 10 ) 927 - 31 2010.10

Language：Japanese Publishing type：Research paper (scientific journal)

The authors report a case of 74-year-old woman suffering thrombosis of the confluence of sinuses after the left occipital transtentorial removal of a pineal region epidermoid cyst. Four days after the operation, the patient developed left homonymous hemianopsia. Magnetic resonance imaging revealed a venous infarct in the right occipital lobe and magnetic resonance venography disclosed a signal defect of the posterior part of the confluence of sinuses. The patients' neurological symptom recovered soon after anticoagulation treatment, and magnetic resonance venography after the sixth week showed recanalization of the confluence of sinuses. Although it might be rare, thrombosis of the dural sinus should be recognized as a complication of craniotomy.
