Persistent primitive trigeminal artery-cavernous sinus fistula with intracerebral hemorrhage: endovascular treatment using detachable coils in a transarterial double-catheter technique - Case report and review of the literature International journal

K Tokunaga, K Sugiu, M Kameda, K Sakai, K Terasaka, T Higashi, Dare, I

JOURNAL OF NEUROSURGERY 101 ( 4 ) 697 - 699 2004.10

Language：English Publisher：AMER ASSOC NEUROLOGICAL SURGEONS

Intracerebral hemorrhage occurred in this 61-year-old woman with preexisting diplopia and proptosis. Results of angiography demonstrated a persistent primitive trigeminal artery (PPTA)-cavernous sinus fistula with cortical venous reflux. Two microcatheters were introduced transarterially through the PPTA into the two draining pathways in the cavernous sinus. Coils were delivered in both pathways simultaneously to prevent further venous overload on either path. The fistula was successfully occluded without complication while the PPTA was preserved. The authors describe this double-catheter technique for coil embolization of a fistula and review the literature concerning PPTA-cavernous sinus fistulas.

Combined use of electrolytically and mechanically detachable platinum coils for endovascular treatment of cerebral aneurysms - Technical note

K Sugiu, A Katsumata, N Kusaka, W Sasahara, K Tokunaga, JB Martin, DA Rufenacht, T Ohmoto

NEUROLOGIA MEDICO-CHIRURGICA 44 ( 5 ) 269 - 273 2004.5

Language：English Publisher：JAPAN NEUROSURGICAL SOC

The combined use of Guglielmi detachable coils (GDCs) and newly developed mechanically detachable platinum coils (Detach Coil System: DCS) was evaluated for the endovascular treatment of 10 patients with cerebral aneurysms. The number and total length of detachable coils placed into the aneurysms, the detaching time for each coil, and any technical problems were recorded and evaluated. Sixty GDCs and 60 DCSs were used. The detachment time for the DCS (mean 21 seconds) was faster than that for the GDC (mean 2 minutes 35 seconds). One DCS moved inside the aneurysm during the mechanical detachment maneuver, but was successfully placed. Neither detachment system influenced the behavior of the other system during coil implantation. The DCS includes a useful J-shape coil, whereas the GDC can be detached safely in fragile aneurysms. The DCS is also cheaper. The coil systems complemented one another and the combination optimized cost and operating time.

Rebleeding of a vertebral artery dissecting aneurysm during stent-assisted coil embolization: A pitfall of the "stent and coil" technique International journal

K Sugiu, K Takahashi, K Muneta, T Ohmoto

SURGICAL NEUROLOGY 61 ( 4 ) 365 - 370 2004.4

Language：English Publisher：ELSEVIER SCIENCE INC

BACKGROUND
A stent-assisted coil embolization has been applied as a novel choice of treatment for vertebral artery dissecting aneurysms (VADAs).
CLINICAL PRESENTATION
A 45-year-old man suffered from subarachnoid hemorrhage three times within 2 hours. The left vertebral angiogram showed a VADA at the distal origin of the posterior inferior cerebellar artery. The right vertebral artery was hypoplastic, and collateral circulation to the posterior fossa was poor.
INTERVENTION
Stent-assisted coil embolization was performed under general anesthesia. The aneurysm was excluded from the circulation with good patency of the vertebral artery, although the fourth coil caused rebleeding from the aneurysmal dome during the procedure.
CONCLUSION
This is the first case report that demonstrates rebleeding from VADA during stent-assisted coil embolization in the acute stage of its rupture. We have to be aware of the risks and be ready to prevent fatal complications with this novel technique. (C) 2004 Elsevier Inc. All rights reserved.

Pseudoxanthoma elasticum with carotid rete mirabile International journal

T Yasuhara, K Sugiu, M Kakishita, Date, I

CLINICAL NEUROLOGY AND NEUROSURGERY 106 ( 2 ) 114 - 117 2004.3

Language：English Publisher：ELSEVIER SCIENCE BV

We describe a case of Pseudoxanthoma elasticum (PXE) in a 14-year-old girl. This case is especially rare because of its association with carotid rete mirabile (CRM). Only three cases have been reported previously in the literature. Although the relation between P. elasticum and carotid rete mirabile is unclear, both disorders are believed to be major risk factors for cerebrovascular disease. (C) 2003 Elsevier B.V.

Training in neurovascular intervention usefulness of in-vitro model and clinical practice

INTERVENTIONAL NEURORADIOLOGY 10 107 - 112 2004.3

Language：English Publisher：EDIZIONI CENTAURO

We introduce our training tools and system of neurovascular intervention. An in vitro cerebral vascular model was used for the young residents to understand the basic interventional techniques and devices.
The model included several vascular lesions such as cerebral aneurysm, dural arterio-venous fistula, or carotid artery stenosis. Endovascular procedures in the model were performed under fluoroscopic or direct visual control, and consecutive haemodynamic changes were visualized by using digital subtraction angiography and direct observation. Thus, traineess could have an easy understanding of clinical conditions. New medical devices, such as platinum coils, were successfully implanted in the model under stable conditions.
After the initial training using vascular model, the residents had started clinical experiences under the control of senior surgeons. Although it is difficult to describe usefulness of our clinical training, we believe that we provide enough good quality and quantity of clinical cases to the residents. Because our endovascular team has recently had150-200 interventional procedures every year, one resident can have experienced more than 100 cases per year The qualification of a Board Certified Specialist of the Japanese Society of Intravascular Neurosurgery (JSIN) requires that, the applicant must have experienced more than 100 cases for four years. So our residents can have enough case materials to qualify the board examination.
