I. OBJECTIVES AND METHODS 1. Objects Between March 2008 and September 2010, 11 patients were diagnosed with smog disease combined with intracranial blood flow-related aneurysms by DSA. Among them, 5 cases were male and 6 cases were female, aged 28-55 years old, with an average of 43.6 years old. Clinical manifestations, symptoms and signs The main clinical symptoms of 7 patients with intracranial hemorrhage were acute severe headache, sudden aphasia, sudden impaired consciousness, etc. Intracranial hemorrhage was confirmed by cranial CT examination, among which there were 5 cases of subarachnoid hemorrhage (1 case combined with an intracerebral hematoma ruptured into the ventricle), and all of them had cervical tonus, and were classified into 1 case of grade I, 2 cases of grade II, and 2 cases of grade III before the operation, and the other 2 cases of intraventricular and intraparenchymal bleeding, respectively. The other two hemorrhages were intraventricular hemorrhage and intracerebral parenchyma hemorrhage; four patients with ischemic symptoms showed focal neurological signs, including dysarthria, incomplete aphasia, mild hemiparesis, and frequent episodes of transient ischemic attack in one case each. 3, Imaging examination 7 patients 11 patients were subjected to head magnetic resonance angiography, digital subtraction angiography and 3D reconstruction of the aneurysm before the operation. 7 cases of unilateral smoky disease and 4 cases of bilateral smoky disease were found in the 11 patients. The aneurysms were shown to be of major arterial type in 9 cases (apical basilar artery in 2 cases, anterior communicating artery in 2 cases, posterior communicating artery in 3 cases, internal carotid artery – anterior choroidal artery in 1 case, posterior cerebral artery in 1 case), and peripheral arterial type in 2 cases (parietal-occipital branch of the posterior cerebral artery in 1 case, and posterior medial artery of the choroid in 1 case). 4. Treatment 9 cases of simple spring coil embolization, 1 case of liquid glue embolization, and 1 case of peripheral artery-type aneurysm (posterior medial choroidal artery aneurysm) were abandoned due to the difficulty of super-selection and the unsatisfactory microcatheterization in place, and were closely followed up with indirect blood flow reconstruction (multipoint cranial drilling). Among the cases of spring coil embolization alone, balloon-assisted spring coil embolization was used in one case (anterior communicating artery aneurysm), and microcatheter neck-plasty-assisted embolization was used in two cases (apex of basilar artery). Endovascular embolization was completed under general anesthesia after angiographic diagnosis. During the operation, systemic heparinization was performed, and after the catheter sheath was placed via the femoral artery, the 6F guide catheter was delivered to the level of the cervical 2-3 vertebrae. The microcatheter was guided by a microguidewire, and the aneurysm was superselected into the aneurysm, and the micro-spring coil was filled with the aneurysm until the aneurysm was completely embolized. If the aneurysm neck was wide and the spring coil could not be stabilized in the aneurysm, the aneurysm neck was remodeled with an occlusion balloon, and then the spring coil was filled; when the wide-necked aneurysm was located at the tip of the basilar artery, a microguidewire was shaped and placed into the posterior cerebral artery of the brain to form a trans-aneurysm neck, and then the platinum microspring coils were filled with an intracapsular electrolysis through the microcatheter. Results Of the 11 patients, except for one peripheral artery type aneurysm where microcatheter over-selection was difficult and embolization was abandoned, the remaining 10 cases were treated endovascularly with good results, and there was not a single case of death, and the results of immediate postoperative embolization of the aneurysm. All smoky patients underwent indirect flow reconstruction after endovascular treatment, and at 6-month to 42-month follow-up, all 7 bleeding-type patients recovered to normal without recurrence of intracranial hemorrhage; all 4 cases of ischemic symptoms improved significantly, and all patients had a Glasgow prognostic classification of V. There were no additional neurological deficits and no new aneurysms. The results of 6-month postoperative follow-up: the peripheral artery-type aneurysms that were not satisfactorily filled with microcatheters in place and were abandoned for embolization were found to have completely disappeared at the 6-month follow-up after indirect flow reconstruction with multipoint cranial drilling; the aneurysms embolized by spring coils were stable at follow-up, with no aneurysmal manifestation, and the aneurysm-carrying arteries were kept patent.
