Systemic multiple aneurysms are rare, and an association between intracranial and visceral arterial or abdominal aortic aneurysm in the same patient is a very rare occurrence. We report herein three such cases. In one case, aneurysms of the right internal carotid artery(ICA) and the right middle cerebral arterial bifurcation(MCAB) coexisted with the inferior pancreaticoduodenal arterial pseudoaneurysm and two ileal arterial aneurysms. In another case, the patient had the A-com arterial aneurysm and the right renal arterial aneurysm. And in the other patient, he had the right vertebral artery dissecting aneurysm with the abdominal aortic aneurym. Initially, all patients were referred to our hospital with subarachnoid hemorrhage(SAH), and thereafter first two patients developed visceral arterial aneurysm rupture in the course of hospital stay and in the last patient, the abdominal aortic aneurysm was detected incidentally during carotid angiogram for Guglielmi detachable coil(GDC) embolization of vertebral dissecting aneurym. After thorough review of our cases together with pertinent literatures, we emphasize the possibility of underlying extracranial aneurysms in ruptured intracranial arterial aneurysm patient and it's uncommon but fatal complication.

Objective : The semi-jailing technique (SJT) provides stent-assisted remodeling of the aneurysm neck during coil embolization without grasping the coil delivery microcatheter. We retrospectively evaluated the efficacy and safety of SJT using a Neuroform3 stent for coiling of wide-necked intracranial aneurysms. Methods : We collected the clinical and radiological data between January 2009 and June 2015 of the wide-necked aneurysms treated with SJT using a Neuroform3 stent. Results : SJT using a Neuroform3 stent was attempted in 70 wide-necked aneurysms (68 patients). There were 56 unruptured and 14 ruptured aneurysms. The size of aneurysm ranged from 1.7 to 28.1 mm (mean 6.1 mm). The immediate angiographic results were complete occlusion in 55 aneurysms (78.6%), neck remnant in 7 (10.0%), and aneurysm remnant in 8 (11.4%). Overall, periprocedural complications occurred in 13 patients (19.1%), including asymptomatic thromboembolism in 7 (10.3%), symptomatic thromboembolism in 4 (5.9%), and symptomatic hemorrhagic complications in 2 (2.9%). Conventional angiography follow-up was obtained in 55 (78.6%) of 70 aneurysms (mean, 10.9 months). The result showed progressive occlusion in 7 aneurysms (12.7%) and recanalization in 1 aneurysm (1.8%). At the end of the observation period (mean, 17.5 months), all 54 patients without subarachnoid hemorrhage showed excellent clinical outcomes (modified Rankin Scale [mRS] 0), except two (mRS 1 or 2) and seven of 14 patients with subarachnoid hemorrhage remained symptom-free (mRS 0). Conclusion : In this report of 70 aneurysms, SJT using a Neuroform3 stent for coiling of wide-necked intracranial aneurysms showed good technical safety, as well as favorable clinical and angiographic outcomes.

Objective : The purpose of this study was to compare computed tomographic angiography(CTA) with conventional cerebral angiography(CCA) and to assess usefulness of CTA in detection and anatomic definition of intracranial aneurysms of the circle of Willis in subarachnoid hemorrhage. Patients and Methods : Fifty consecutive patients with known or suspected intracranial saccular aneurysms underwent CTA with preoperative CCA from 1997 to 1999. Using surface shaded display post-processing technique, CTA was interpreted for the presence, location of aneurysms and anatomic features. The image obtained with CTA was then compared with CCA image. Results : In 47 patients, CCA revealed 57 cerebral aneurysms and CTA revealed 54 aneurysms. Two of the 57 cerebral aneurysms were located outside of the imaging volume of CTA and one case was misdiagnosed. The sensitivity of CTA was 94.7% and the specificity was 100%. The results obtained with CTA were, compared with the results obtained with CCA, equal in determining dome shape, direction and lobularity. However, CTA provided a 3-dimensional representation of aneurysmal lesion very useful for surgical planning. Moreover, CTA was useful for rapid and relatively noninvasive detection of aneurysms in the circle of Willis. Conclusion : CTA can be a diagnostic tool for the patients with acute subarachnoid hemorrhage due to a ruptured aneurysm of the circle of Willis and provides adequate anatomic detail for surgical planning, especially to complex cerebral aneurysms. However, we think CCA is necessary because of CTA limitations including its difficulty in detecting unusually located aneurysms(including those in cavernous sinus or distal artery) and combined vascular lesion (including arteriovenous malformation) and acquiring dynamic flow information.

Objective : To evaluate the usefulness of a cranial implantable chemoport, the H-port, as an alternative to the Ommaya reservoir for intraventricular chemotherapy/cerebrospinal fluid (CSF) access in patients with leptomeningeal metastasis (LM). Methods : One hundred fifty-two consecutive patients with a diagnosis of LM and who underwent H-port installation between 2015 and 2021 were evaluated. Adverse events associated with installation and intraventricular chemotherapy, and the rate of increased intracranial pressure (ICP) control via the port were evaluated for safety and efficacy. These indices were compared with published data of Ommaya (n=89), from our institution. Results : Time-to-install and installation-related complications of intracranial hemorrhage (n=2) and catheter malposition (n=5) were not significantly different between the two groups. Intraventricular chemotherapy-related complications of CSF leakage occurred more frequently in the Ommaya than in the H-port group (13/89 vs. 3/152, respectively, p<0.001). Intracranial hemorrhage during chemotherapy occurred only in the Ommaya group (n=4). The CSF infection rate was not statistically different between groups (14/152 vs. 12/89, respectively). The ICP control rate according to reservoir type revealed a significantly higher ICP control rate with the H-port (40/67), compared with the Ommaya result (12/58, p<0.001). Analyzing the ICP control rate based on the CSF drainage method, continuous extraventricular drainage (implemented only with the H-port), found a significantly higher ICP control rate than with intermittent CSF drainage (33/40 vs. 6/56, respectively, p<0.0001). Conclusion : The H-port for intraventricular chemotherapy in patients with LM was superior for ICP control; it had equal or lower complication rates than the Ommaya reservoir.

This study reported the case of a patient with quadriparesis due to cerebral aneurysm rupture, subarachnoid hemorrhage, and intraventricular hemorrhage (IVH) treated with Korean medicine. The patient was treated with acupuncture, herbal medicine (mainly Tonggyuhwalhyeol-tang-gagam), Western medicine, moxibustion, cupping, and rehabilitative therapy for 75 days, and improved after administration. After treatment, the Manual Muscle Test grade improved from 4/4-/3+/3 to 4+/4+/4+/4+, the Korean version of the modified Barthel Index score improved from 9 to 100, the National Institute of Health's Stroke Scale score improved from 2 to 0, the Global Deterioration Scale score improved from 3 to 2, and the Korean version of the Mini-Mental State Examination score improved from 22 to 30. During administration, the patient did not show seizures, shock, or loss of consciousness, and the vital signs were stable in the normal range. We followed up the brain computed tomography findings for 2 times and found that there was no definite evidence of intracranial hemorrhage or IVH or re-rupture or rebleeding after Korean medicine treatment. This study suggests that Korean medicine treatment with blood-invigorating and stasis-removing herbs could be a safe and effective intervention option for improving quadriparesis due to cerebral aneurysm rupture and subarachnoid hemorrhage.

Objective : About 40% of patients who admit to the hospital after subarachnoid hemorrhage are poor clinical grade(Hunt-Hess grade IV, V). The majority of these patients have been excluded from early, aggressive treatment. The current study was undertaken to evaluate the outcome of urgent surgery for Hunt-Hess grade IV aneurysmal subarachnoid hemorrhage. Materials and Methods : We reviewed hospital records and radiographic studies of 36 patients who were Hunt-Hess grade IV among 201 cases with ruptured intracranial aneurysm admitted between Sep. 1995 and Dec. 2000. Operated patients were treated with urgent angiography and surgery within 24 hours of presentation, except six patients, and medical records of these patients were reviewed for the clinical course and Glasgow outcome scale(GOS). Results : Overall management results of the 36 patients were good recovery in 13(36.1%), moderate disability in 12 (33.3%), severe disability in 1(2.8%), vegetative state in 1(2.8%) and 9(25.0%) of surgically treated patients had died. Conclusion : Although with limited number of patients, we conclude that urgent surgery for Hunt-Hess grade IV patients results in a better neurologic outcome and urgent surgery combined with aggressive postoperative management can minimize mortality.

Objective : Long-term oral anticoagulation or antiplatelet therapy has been used with increasing frequency in the elderly. These patients are at increased risk of morbidity and mortality from expansion of intracranial hemorrhage. We conducted a single-center retrospective case control study to evaluate risk factors associated with outcomes and to identify the differences in outcome in traumatic brain injury between preinjury anticoagulation use and without anticoagulation. Methods : A retrospective study of patients who underwent craniotomy or craniectomy for acute traumatic cerebral hemorrhage, between January 2005 and December 2014 was performed. Results : A consecutive series of 50 patients were evaluated. The factors significantly differed between the two groups were initial Prothrombin Time-International Normalized Ratio, initial platelet count, initial Glasgow Coma Scale score, and postoperative intracranial bleeding. Mean Glasgow Outcome Scale (GOS) score were similar between the two groups. In the patient with low-energy trauma only, no significant differences in GOS score, postoperative bleeding and many other factors were observed. The contributing factors to postoperative bleeding was preinjury anticoagulation and its adjusted odds ratio was 12 [adjusted odds ratio (OR), 12.242; p=0.0070]. The contributing factors to low GOS scores, which mean unfavorable neurological outcomes, were age (adjusted OR, 1.073; p=0.039) and Rotterdam scale score for CT scans (adjusted OR, 3.123; p=0.0020). Conclusion : Preinjury anticoagulation therapy contributed significantly to the occurrence of postoperative bleeding. However, preinjury anticoagulation therapy in the patients with low-energy trauma did not contribute to the poor clinical outcomes or total hospital stay. Careful attention should be given to older patients and severity of hemorrhage on initial brain CT.

Objective : The authors report our experience of urokinase thrombolysis in treating patients harboring nonaneurysmal spontanesous intraventricular hemorrhage[IVH] and evaluated complications, safety and feasibility of this procedure retrospectively. Methods : Fifty-three patients with nonaneurysmal IVH>15mL without underlying structural etiology or coagulopathy were recruited. The patients with Glasgow Coma Scale[GCS]<5 were excluded. A catheter was directed into the IVH. Hematoma aspiration was followed by instillation of urokinase at the ear level of drainage bag under intracranial pressure monitoring system. This was repeated every 6hours until half of its initial volume. For analysis of prognostic factors, we classified the patients into two groups by Glasgow outcome scale[GOS]; good [$GOS\;{\ge}3$] and bad [GOS<3] prognosis group, and performed comparative analysis between two groups. Results : Mean age was 60.2years. The baseline hematoma size ranged 16 to 72mL. IVH volume reduction was done by an average of 74.2%. As complications, there were 3cases of rebleeding and 2cases of ventriculitis. No intracranial adverse effects were observed during thrombolytic theraphy. At 6months after the procedure, 29patients had achieved a good recovery, 15remained vegetative. 9patients died in hospital. The main good prognostic factors were young age, small IVH volume, and high GCS. Conclusion : The results of this study suggest that this relatively easy and safe method of treatment will improve the prognosis. However, further clinical studies also must assess optimal thrombolytic dosage, frequency, and timing of urokinase instillation for safety and effectiveness and must include controlled comparisons of mortality, disability outcome, quality of life, time until convalescence, and cost of care in treated and untreated patients.
