Background/Aims: Gastric varices (GVs) are a major cause of upper gastrointestinal bleeding in patients with liver cirrhosis. The current treatments of choice are balloon-occluded retrograde transvenous obliteration (BRTO) and the placement of a transjugular intrahepatic portosystemic shunt (TIPS). We aimed to compare the efficacy and outcomes of these two methods for the management of GV bleeding. Methods: This retrospective study included consecutive patients who received BRTO (n=157) or TIPS (n=19) to control GV bleeding from January 2005 to December 2014 at a single tertiary hospital in Korea. The overall survival (OS), immediate bleeding control rate, rebleeding rate and complication rate were compared between patients in the BRTO and TIPS groups. Results: Patients in the BRTO group showed higher immediate bleeding control rates (p=0.059, odds ratio [OR]=4.72) and lower cumulative rebleeding rates (logrank p=0.060) than those in the TIPS group, although the difference failed to reach statistical significance. There were no significant differences in the rates of complications, including pleural effusion, aggravation of esophageal varices, portal hypertensive gastropathy, and portosystemic encephalopathy, although the rate of the progression of ascites was significantly higher in the BRTO group (p=0.02, OR=7.93). After adjusting for several confounding factors using a multivariate Cox analysis, the BRTO group had a significantly longer OS (adjusted hazard ratio [aHR]=0.44, p=0.01) and a longer rebleeding-free survival (aHR=0.34, p=0.001) than the TIPS group. Conclusions: BRTO provides better bleeding control, rebleeding-free survival, and OS than TIPS for patients with GV bleeding.
Objective : We analysed diverse clinical features of the cavernous angioma. Also, we report the experience in differ-ent methods of the management and their results. Method : Data from 80 patients who were confirmed pathologically or diagnosed radiologically between Jan. 1990 and Sept. 1998 at our hospital were analysed. Variable factors that were examined were : clinical features, effects of treatment, and complications. Results : There were 47 male and 33 female patients. The age at the first presentation was from 3 to 57(mean 34.1) years old. Clinical features were seizure in 28 cases(38%), bleeding in 24 cases(32%), neurologic deficits in 12 cases(16%), headache in 10 cases(14%), and six incidental cases. The locations of lesion were cerebral and cerebellar hemisphere in 45 cases(56.2%), brainstem, basal ganglia, and thalamus in 32 cases(40%), multiple in 3 cases (3.8%). Seizure was common at the third decade and occurred frequently with the cavernous angioma in temporal (43%) or frontal lobe(39%). Bleeding was frequent after the third decade with peak at the fourth decade and had high incidence in brainstem or thalamus. The gamma-knife radiosurgery was done in 47 cases. Rebleeding occurred in 3 cases, but it was within postradiosurgery 1 year. Symptomatic radiation change occurred in 2 cases of 8 radiation change on MRI. On follow-up MRI, no evidence of rebleeding was found in 30 cases. Also, The lesion size was decreased in 3 cases. Resection was performed in 23 cases ; total 20, subtotal 2, partial 1. Postoperative complication occurred in 6 cases(26.1%). After surgery, 7(63.6%) of 11 seizure patients had outcome of seizure-free. Subclinical rebleeding occurred in one of two subtotal resected cases. In 11 patients, conservative management was done. There was neither rebleeding nor symptom aggravation during follow-up period of mean 17.2 months. Conclusion : The solution for prevention of rebleeding is complete removal of the lesion located at noneloquent area or accessible region, especially for the patients who presented symptoms or intractable seizure. However, the Gamma knife radiosurgery is considered when the lesions are located at eloquent area or when severe postoperative morbidity is expected.
Objective : Although surgical clipping of intracranial aneurysm is the definite method of treatment, there remains a small number of patients in whom surgical clipping is not technically possible. In such difficult cases, surgeon has to consider other therapeutic alternatives. In this report, we analyze our aneurysmal cases treated by wrapping and coating method and evaluate their surgical outcome and follow-up results. Method : Among the total of 877 patients operated from 1990 to 1999 for intracranial aneurysms at our hospital, 40 cases(4.6%) were treated by wrapping and coating method. They included 24 cases of single ruptured aneurysms and 16 with unruptured ones in multiple aneurysms. Wrapping with temporalis muscle and/or muslin gauze and coating with bioadhesive agent such as fibrin glue were performed. Result : Wrapping and coating method was performed mostly to the anterior communicating artery aneurysm (35%), and mostly because of the broad-based neck of an aneurysm(43%). At the time of discharge, 30 out of 40 patients(80%) showed favourable outcome and three cases died. The patients were monitored for average of 37 months(3-75 months). Among 24 cases with single ruptured aneurysm, 4 cases(17%) had early rebleeding within 6 months from the initial hemorrhage, and such rebleeding occurred within the first postoperative month in 3 cases. However, there was no rebleeding after the 6 months. Among 16 patients whose aneurysms were unruptured ones, none of them showed bleeding episode. Conclusion : It seems likely that the wrapping and coating method would be some help to prevent the rebleeding of an intracranial aneurysm. In order to obtain more accurate results regarding the efficacy of such method, it will be necessary to perform a multi-center study for longer follow-up periods and various wrapping and coating materials.

Purpose: Recent advancements in interventional radiology have made angioembolization an invaluable modality in trauma care. Angioembolization is typically performed by interventional radiologists. In this study, we aimed to investigate the safety and efficacy of emergency angioembolization performed by trauma surgeons. Methods: We identified trauma patients who underwent emergency angiography due to significant trauma-related hemorrhage between January 2020 and June 2023 at Jeju Regional Trauma Center. Until May 2022, two dedicated interventional radiologists performed emergency angiography at our center. However, since June 2022, a trauma surgeon with a background and experience in vascular surgery has performed emergency angiography for trauma-related bleeding. The indications for trauma surgeon-performed angiography included significant hemorrhage from liver injury, pelvic injury, splenic injury, or kidney injury. We assessed the angiography results according to the operator of the initial angiographic procedure. The term "failure of the first angioembolization" was defined as rebleeding from any cause, encompassing patients who underwent either re-embolization due to rebleeding or surgery due to rebleeding. Results: No significant differences were found between the interventional radiologists and the trauma surgeon in terms of re-embolization due to rebleeding, surgery due to rebleeding, or the overall failure rate of the first angioembolization. Mortality and morbidity rates were also similar between the two groups. In a multivariable logistic regression analysis evaluating failure after the first angioembolization, pelvic embolization emerged as the sole significant risk factor (adjusted odds ratio, 3.29; 95% confidence interval, 1.05-10.33; P=0.041). Trauma surgeon-performed angioembolization was not deemed a significant risk factor in the multivariable logistic regression model. Conclusions: Trauma surgeons, when equipped with the necessary endovascular skills and experience, can safely perform angioembolization. To further improve quality control, an enhanced training curriculum for trauma surgeons is warranted.
Computed tomography angiography (CTA) is commonly used in setting of subarachnoid hemorrhage, but imaging features of aneurysm rupturing taking place at the time of scanning has rarely been described. The author reports a case of actively rebleeding aneurysm of the anterior communicating artery with intraventricular extravasation on the hyperacute CTA imaging. The rebleeding route, not into the third ventricle but into the lateral ventricles, can be visualized by real-time three-dimensional CT pictures. The hemorrhage broke the septum pellucidum and the lamina rostralis rather than the lamina terminalis.
Objective : There have been numerous follow-up studies of patients who had ruptured or unruptured intracranial aneurysms treated by wrapping technique using various materials have been reported. Our objective was to ascertain whether our particular wrapping technique using the temporalis muscle provides protection from rebleeding and any aneurysm configuration changes in follow-up studies. Methods : Clinical presentation, the location and shape of the aneurysm, outcomes at discharge and last follow-up, and any aneurysm configuration changes on last angiographic study were analyzed retrospectively in 21 patients. Reinforcement was acquired by clipping the wrapped temporalis muscle. Wrapping and clipping after incomplete clipping was also done. Follow-up loss and non-angiographic follow-up patient groups were excluded in this study. Results : The mean age was 53 years (range 29-67), and 15 patients were female. Among 21 patients, 10 patients had ruptured aneurysms (48%). Aneurysms in 21 patients were located in the anterior circulation. Aneurysm shapes were broad neck form (14 cases), fusiform (1 case), and bleb to adjacent vessel (6 cases). Five patients were treated by clipping the wrapped temporalis, and 16 patients by wrapping after partial clipping. The mean Glasgow coma scale (GCS) at admission was 14.2. The mean Glasgow outcome scale (GOS) at discharge was 4.8, and 18 patients were grade 5. The mean period between initial angiography and last angiography was 18.5 months (range 8-44). Aneurysm size was not increased in any of these patients and configuration also did not change. There was no evidence of rebleeding in any of these treated aneurysms. Conclusion : Our study results show that wrapping technique, using the temporalis muscle and aneurysm clip(s), for intracranial aneurysm treatment provides protection from rebleeding or regrowth.
Objective : Blood blister-like aneurysms (BBAs) resemble arterial dissections. The purpose of this study was to investigate the relationship between these two disease entities and highlight commonalities and distinct features. Methods : Among 871 consecutive patients with aneurysmal subarachnoid hemorrhage, 11 BBAs of internal carotid artery and seven vertebral artery dissections (VADs) with a short segmental eccentric dilatation (Mizutani type 4), which is morphologically similar to a BBA, were selected. The following clinical factors were studied in each group : age, gender, risk factors, Hunt and Hess grade (HHG), Fisher grade (FG), vasospasms, hydrocephalus, perioperative rebleeding rate, and treatment outcome. Results : The mean age was 47.9 years in the BBAs group and 46.4 years in the type 4 VADs group. All the BBA patients were female, whereas there was a slight male predominance in the type 4 VAD group (male : female ratio of 4 : 3). In the BBA and type 4 VAD groups that underwent less aggressive treatment to save the parent artery, 29% (n=2/7) and 66.6% (n=2/3), respectively, eventually required retreatment. Perioperative rebleeding occurred in 72.7% (n=8) and 28.6% (n=2) of patients in the BBA and type 4 VAD groups, respectively. There was no statistical difference in the other clinical factors in both groups, except for the male dominancy in the type 4 VAD group (p=0.011). Conclusion : BBAs and ruptured type 4 VADs have a similar morphological appearance but there is a distinct clinical feature in gender and perioperative rebleeding rates. Complete isolation of an aneurysm from the parent artery might be the most important discipline for the treatment of these diseases.
Objective : The present study evaluated overall surgical results for 3,000 patients with intracranial aneurysms, operated on in Busan Paik Hospital institution. Methods : Three thousand aneurysm cases, operated on in Busan Paik Hospital between January 1980 to June, 15th, 2005, were evaluated based on the following criteria; aneurysm form, aneurysm location, surgical results, postoperative complications, and seasonsonality of occuence. 957 cases were anterior communicating artery aneurysms, 776 were internal carotid artery[ICA] aneurysms, 755 were middle cerebral artery[MCA] aneurysms, 96 were anterior cerebral artery[ACA] aneurysms, 128 were vertebro-basilar artery[VBA] aneurysms and 288 were multiple aneurysms. The male to female ratio was 0.7 to 1 Surgical methods included 2.738 clippings, 219 coating and wrappings, 23 aneurysmoraphies, 20 proximal ligations. Results : Rebleeding occured in 5.1% of the early operation group and 16% of the late operation group respectively. Incidence of clinical vasospasm was 166% and angiographic vasospasm was 24.1%. The percentage of the multiple aneurysms was 9.5%, the percentage of the dissecting aneurysm was 6 cases [0.2%], 6 of the total [0.2%];De Novo" aneurysm, the percentage of lobectomies with clipping cases was 9 cases [03%] the percentage were incidental aneurysms; 164 [5.5%]. 88.1% had overall favorable surgical results with a 5.5 % mortality rate. Calcium-channel blocker and "Triple H" therapy did not improve mortality but did significantly improve morbidity. In the old age group, early operation reduced vasospasm, rebleeding and medical complications. The early surgery group exhibited a 86.2% favorable outcome with a 8.1% mortality rate. Intraoperative angiography reduced residual or remained aneurysms in large, giant aneurysm, especially in A.com artery aneurysm. Conclusion : The surgical results for the early surgery group according to surgical timming was better, but there were not statistically significant. ntraoperative angiography was especially useful on large aneurysms of the anterior communicating artery.
Objective : Given the high risk of rebleeding and recurrence of blood blister-like aneurysms (BBAs), we treated ruptured BBAs of the internal carotid artery (ICA) with stent-assisted coil embolization (SAC). This study aimed to evaluate the efficacy and safety of SACs. Methods : We retrospectively reviewed clinical and radiological data from eight patients with ruptured BBAs of the supraclinoid ICA. The modified Rankin Scale (mRS) was used to assess clinical outcomes, while radiological outcomes were evaluated on angiographs. For a pooled analysis, data from literature reporting the outcomes of ruptured BBAs treated with SAC were collected and analyzed in conjunction with our data. Results : In our cohort, the mean Raymond classification score was 1.57±0.53 immediately after initial endovascular treatment. There were no perioperative complications or rebleeding events during the follow-up period. The mean mRS score at patient discharge was 1.00±0.81 and improved to 0.28±0.48 by the last follow-up day. The recurrence rate was 25% with an asymptomatic presentation and successful treatment with multiple stent insertion. Pooled analysis of 76 cases of SAC revealed a complete occlusion rate immediately after treatment of 54.8%, rebleeding rate 7.94%, and recurrence rate 24.2%. Good clinical outcomes with mRS score 0-2 were observed in 89.9% by the last clinical follow-up. Total mortality rate was 7.7%. Conclusion : This treatment appears to not only minimize the hemodynamic burden on the fragile dome specific to this type of aneurysm, but also provides an opportunity for safe and effective treatment in recurrent cases.
Objective : The present study attempts to address the change of management results over time during the past 13 years in good-grade patients with intracranial aneurysm. Methods : Six hundred twenty five [Hunt-Hess grade I to III] out of 826 patients with ruptured intracranial aneurysms operated by the same operator within 3 days after the attack from 1990 to 2002 were selected. Since 1998, endovascular aneurysmal occlusion was done in selected cases of 21 patients. The change of management results over time, including rebleeding rate, delayed ischemic neurologic deficit[DIND] as a cause of morbidity and mortality and surgical outcome were examined. Results : The ratio of poor-grade patients in all patients tended to decrease over the years. The early rebleeding rate declined from 5.0% to 1.2% with the use of tranexamic acid and computed tomography angiogram DIND as a cause of mortality and morbidity has decreased from 12.5% in 1990 to approximately 0% currently. Surgical outcome began to improve significantly in 1994 [poor outcome : 25% in 1990, 12.2% in 1994,6.8% in 2002]. Conclusion : These results suggest that the advances in care and increased experience of the operator significantly affect the change of overall outcome, and early detection of the aneurysm is needed for reducing the ratio of poor-grade patients.
