Resuscitative endovascular balloon occlusion of the aorta (REBOA) is considered an emerging adjunct therapy for profound hemorrhagic shock, as it can maintain temporary stability until definitive repair of the injury. However, there is limited information about the use of this procedure in children. Herein, we report a case of REBOA in a pediatric patient with blunt trauma, wherein the preoperative deployment of REBOA played a pivotal role in damage control resuscitation. A 7-year-old male patient experienced cardiac arrest after a motor vehicle accident. After 30 minutes of cardiopulmonary resuscitation, spontaneous circulation was achieved. The patient was diagnosed with massive hemoperitoneum. REBOA was then performed under ongoing resuscitative measures. An intra-aortic balloon catheter was deployed above the supraceliac aorta, which helped achieved permissive hypotension while the patient was undergoing surgery. After successful bleeding control with small bowel resection for mesenteric avulsion, thorough radiologic evaluations revealed hypoxic brain injury. The patient died from deterioration of disseminated intravascular coagulation. Although the patient did not survive, a postoperative computed tomography scan revealed neither remaining intraperitoneal injury nor peripheral ischemia correlated with the insertion of a 7-Fr sheath. Hence, REBOA can be a successful bridge therapy, and this result may facilitate the further usage of REBOA to save pediatric patients with non-compressible torso hemorrhage.

Objective : Sudden major cerebral artery occlusion often resists recanalization with currently available techniques or can results in massive symptomatic intracranial hemorrhage (sICH) after thrombolytic therapy. The purpose of this study was to examine mechanical recanalization with a retrievable self-expanding stent and balloon in acute intracranial artery occlusions. Methods : Twenty-eight consecutive patients with acute intracranial artery occlusions were treated with a Solitaire retrievable stent. Balloon angioplasty was added if successful recanalization was not achieved after stent retrieval. The angiographic outcome was assessed by Thrombolysis in Cerebral Infarction (TICI) and the clinical outcomes were assessed by the National Institutes of Health Stroke Scale (NIHSS) and the modified Rankin Scale (mRS). Results : At baseline, mean age was 69.4 years and mean initial NIHSS score was 12.5. A recanalization to TICI 2 or 3 was achieved in 24 patients (85%) after stent retrieval. Successful recanalization was achieved after additional balloon angioplasty in 4 patients. At 90-day follow-up, 24 patients (85%) had a NIHSS improvement of ${\geq}4$ and 17 patients (60%) had a good outcome (mRS ${\leq}2$). Although there was sICH, there was one death associated with the procedure. Conclusion : Mechanical thromboembolectomy with a retrievable stent followed by additional balloon angioplasty is a safe and effective first-line therapy for acute intracranial artery occlusions especially in case of unsuccessful recanalization after stent thrombectomy.

Objective : To assess the feasibility, safety, and effectiveness of the balloon-assisted technique with HyperForm balloon in the endovascular treatment of wide-necked intracranial aneurysms. Methods : A total of 34 patients with 34 wide-necked intracranial aneurysms were treated with endovascular coil embolization using balloon-assisted technique with Hyperform balloon. Twenty-nine aneurysms (85.3%) were located in the anterior circulation. The group of patients was comprised of 16 men and 18 women, aged 33 to 72 years (mean : 60.6 years). The size of aneurysms was in the range of 2.0 to 22.0 mm (mean 5.5 mm) and one of neck was 2.0 to 11.9 mm (mean 3.8 mm). The dome to neck ratio was ranged from 0.83 to 1.43 (1.15). Sixteen patients were treated for unruptured aneurysms and the remaining 18 presented with a subarachnoid hemorrhage. Results : In the 34 aneurysms treated by the remodeling technique with HyperForm balloon, immediate angiographic results consisted of total occlusion in 31 cases (91.2%) and partial occlusion in three cases (8.8%). There were five procedure-related complications (14.7%), including two coil protrusions and three thromboembolisms; Except one patient, all were successfully resolved without permanent neurologic deficit. No new bleeding occurred during the follow-up. Twenty patients (59%) underwent angiographic follow-up from 2 to 33 months (mean 9.2 months) after treatment. Focal recanalization with coil compaction of the neck portion was observed in 5 cases (25%). Only one case showed major recanalization and underwent stent-assisted coil embolization. Conclusion : The balloon-assisted technique with Hyperform balloon is a feasible, safe, and effective endovascular treatment of wide-necked cerebral aneurysms.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) has recently gained popularity as an adjunct to resuscitation of patients with traumatic shock. However, the effectiveness of REBOA is still debated because of inconsistent indications across centers and the lack of medical records. The purpose of this study was to investigate the effectiveness and feasibility of REBOA by analyzing clinical results from a single center. Methods: This study included 96 patients who underwent REBOA between August 2016 and September 2021 at a regional trauma center according to the center's treatment algorithm for traumatic shock. Medical records, including the time of the decision to conduct the REBOA procedure, time of operation, type of aortic occlusion, and clinical outcomes, were collected prospectively and analyzed retrospectively. Patients were classified by REBOA protocol (group 1, 2, or 3) and survival status (survivor or non-survivor) for analysis. Results: The overall success rate of the procedure was 97.9%, and the survival rate was 32.6%. In survivors, blood pressure was higher than in non-survivors both before the REBOA procedure (p=0.002) and after aortic occlusion (p=0.03). The total aortic occlusion time was significantly shorter (p=0.001) and the proportion of partial aortic occlusion was significantly higher (p=0.014) among the survivors. The non-survivors had more acidosis (p<0.001) and higher lactate concentrations (p<0.001) than the survivors. Conclusion: REBOA may be a feasible bridge therapy for resuscitation of patients with traumatic shock. Prompt and accurate decision-making to perform REBOA followed by damage control surgery could improve survival rates and clinical outcomes.

The role of resuscitative endovascular balloon occlusion of the aorta (REBOA) in hemodynamically unstable pancreatic trauma is unclear. We report here a case of traumatic pancreatic bleeding controlled with REBOA and angioembolization of the splenic artery before surgery. A 65-year old man experienced blunt trauma upon falling from a height of 20 m. Computed tomography (CT) revealed distal pancreatic trauma (grade III) and contrast extravasation around the splenic artery. Shortly after CT, his systolic blood pressure was 60 mmHg and REBOA was performed for hemodynamic stability. His systolic pressure increased to 130 mmHg after balloon inflation and angioembolization of the splenic artery was performed. On angiography, no further arterial bleeding was identified and the balloon was removed. Subsequently, the patient underwent emergent laparotomy with distal pancreatectomy. There was no active bleeding during surgery and distal main pancreatic duct injury was identified. After surgery, the patient recovered without complication. In this case, hemodynamically unstable hemorrhagic pancreatic trauma was treated effectively and safely with distal pancreatectomy after REBOA with angioembolization.

Abdominal organs are the most vulnerable body parts under vehicle trauma, and there is high mortality from acute injuries in accidents. There are various ways to reduce this high mortality; one method is Resuscitative Endovascular Balloon Occlusion of the Aorta, which has recently become very popular as a minimally invasive alternative in the emergent management of patients with non-compressible hemorrhages below the diaphragm. However, high safety factor for patients is applied in actual clinical practice because there is no exact standard for the operating time. Therefore, in this study, the effects of the mechanical behavior of organ tissues for the duodenum, kidney, and liver on the operating time of Resuscitative Endovascular Balloon Occlusion of the Aorta is investigated in order to obtain data needed to establish standards of operating time. In characteristic analysis of organ tissues, uniaxial tensile test and compression test are conducted according to the operating time.

Purpose: There is increasing evidence in the literature regarding resuscitative endovascular balloon occlusion of the aorta (REBOA) globally, but few cases have been reported in Korea. We aimed to describe our experience of successful Zone III REBOA and to discuss its algorithm, techniques, and related complications. Methods: We reviewed consecutive cases who survived from hypovolemic shock after Zone III REBOA placement for 4 years. We reviewed patients' baseline characteristics, physiological status, procedural data, and outcomes. Results: REBOA was performed in 44 patients during the study period, including 10 patients (22.7%) who underwent Zone III REBOA, of whom seven (70%) survived. Only one patient was injured by a penetrating mechanism and survived after cardiopulmonary resuscitation. All patients underwent interventions to stop bleeding immediately after REBOA placement. Conclusions: This case series suggests that Zone III REBOA is a safe and feasible procedure that could be applied to traumatic shock patients with normal FAST findings who receive a chest X-ray examination at the initial resuscitation.

A carotid artery resection and replacement including neck dissection are used as a method of treatment for head and neck cancer with infiltration into the carotid artery. The recent development of imaging technique makes it easy to estimate the detailed anatomical relationship between the tumor infiltration into the carotid artery, it's resection and replacement are indicated at radical neck dissection. To detect any possibility of cerebral ischemia at the time of ligation of carotid artery, a temporary occlusion test of internal carotid artery with a ballon catheter (balloon occlusion test) is performed. Recently, we performed a carotid artery resection and replacement using an artificial vessel Gore-Tex) in a case of neck cancer with infiltration into the carotid artery.

Objective : Mechanical thrombectomy (MT) for acute intracranial internal carotid artery (ICA) occlusion is often complicated by difficult revascularization and non-involved territory embolization possibly related with larger clot-burden. This study aims to evaluate the efficacy of proximal aspiration thrombectomy (PAT) using a balloon-tipped guide catheter for clot-burden reduction in such cases with period-to-period analysis (period 1 : standard MT without PAT; period 2 : PAT first, then standard MT for the remaining occlusion). Methods : Eighty-six patients who underwent MT for acute intracranial ICA occlusion were included in this analysis from the prospectively maintained stroke registry (33 patients in period 1 and 53 in period 2). In period 2, 'responder' was defined as a case where some amount of clot was retrieved by PAT and the following angiography showed partial or full recanalization. Results : Fifteen of fifty-three patients in period 2 (28.3%) were 'responders' to PAT. There was a significantly higher incidence of atrial fibrillation in the 'responder' subgroup. Period 2 showed a significantly shorter puncture-to-reperfusion time (94.5 minutes vs. 56.0 minutes; p=0.002), a significantly higher Thrombolysis in Cerebral Infarction of 2b-3 reperfusion (45.5% vs. 73.6%; p=0.009), but only a trend for better 3-month favorable outcome (mRS 0-2; 36.4% vs. 54.7%; p=0.097). There was no increase in the incidence of procedure-related complications or intracranial hemorrhage in period 2. Conclusion : A strategy of PAT before standard MT may result in shorter puncture-to-reperfusion time and better angiographic outcome than a strategy of standard MT for acute intracranial ICA occlusion.

Fusiform aneurysms on the basilar artery (BA) trunk are rare. The microsurgical management of these aneurysms is difficult because of their deep location, dense collection of vital cranial nerves, and perforating arteries to the brain stem. Endovascular treatment is relatively easier and safer compared with microsurgical treatment. Selective occlusion of the aneurysmal sac with preservation of the parent artery is the endovascular treatment of choice. But, some cases, particularly giant or fusiform aneurysms, are unsuitable for selective sac occlusion. Therefore, endovascular coiling of the aneurysm with parent vessel occlusion is an alternative treatment option. In this situation, it is important to determine whether a patient can tolerate parent vessel occlusion without developing neurological deficits. We report a rare case of fusiform aneurysms in the BA trunk. An 18-year-old female suffered a headache for 2 weeks. Computed tomography and magnetic resonance image revealed a fusiform aneurysm of the lower basilar artery trunk. Digital subtraction angiography revealed a $7.1{\times}11.0$ mm-sized fusiform aneurysm located between vertebrovasilar junction and the anterior inferior cerebellar arteries. We had good clinical result using endovascular coiling of unruptured fusiform aneurysm on the lower BA trunk with parent vessel occlusion after confirming the tolerance of the patient by balloon test occlusion with induced hypotension and accompanied by neurophysiologic monitoring, transcranial Doppler and single photon emission computed tomography. In this study, we discuss the importance of preoperative meticulous studies for avoidance of delayed neurological deficit in the patient with fusiform aneurysm on lower basilar trunk.
