The posterior nasal bleeding sometimes develope a life threatening situation because of its limited access and the profuse vascular network of the bleeding area. There are various methods of hemostasis including packing, cautery, and arterial ligation those vary in effectiveness. But sometimes patients cannot tolerate these methods or show rebleeding sign. So, if all of these methods are not successful, we should consider the further treatment. The selective angiographic embolization has various advantages such as rapidness, repetition, good visualization, and being performed under local anesthesia, therefore it can provide useful way in patients with massive, intractable posterior nasal bleeding. We report a case of angiographic embolization for intractable posterior nasal bleeding patient and review the effectiveness of the this treatment.

Purpose: To analyze the clinical and angiographic features with outcome of transcatheter arterial embolization in patients with secondary postpartum hemorrhage. Materials and Methods: Clinical details and angiographic features with assessment of arterial embolization were reviewed in total 38 patients underwent arterial embolization at single tertiary referral center. Results: Twenty patients (53%) had Cesarean section. The major causes of bleeding were iatrogenic vascular injury, and retained placenta (55%). The patterns of vaginal bleeding were recorded as intermittent (50%), or as persistent (50%). Seven patients (18%) were hemodynamically unstable at presentation. Positive angiographic findings appeared in eighteen patients (47.3%). The frequency of pseudoaneurysm was statistically high in the Cesarean section (p < 0.001). The used embolic agents except gelfoam were N-butyl cyanoacrylate (n = 7), and microcoil (n = 7). Unilateral selective embolization (26.3%) was shown effective in superselective embolization of bleeding focus. Technical and clinical success rate were 100% and 97.4%, respectively with no complication. Sixteen resumed regular menstruation, and one pregnancy were observed in patients with available follow-up of over 6 months. Conclusion: Considerable rate of hemodynamically unstable patients was observed with high rate of positive angiography findings. Given high successful rate and few complications, early angiographic assessment with embolization should be considered.

Lat. abdominal wall hematoma with active bleeding is very rare but need prompt bleeding control. We report successful treatment by angiographic embolization of superficial circumflex iliac artery rupture caused by blunt trauma. A 60-year-old woman presented painful, enlarging, lat. abdominal wall mass with ecchymosis caused by blunt abdominal trauma. Contrast leakage of superficial circumflex iliac a. within the lt. ext. oblique m. hematoma was confirmed by abdominal computed tomography. Angiographic embolization was performed successfully. Patient was discharged at 4th day after trauma without complication. Angiographic embolization is important treatment option of lat. abdominal wall hematoma with active bleeding replacing emergency surgery.

Dental implantation in the mandibular anterior region is considered a safe and reliable surgical procedure. On the other hand, several articles have reported that inadvertent hemorrhage of the sublingual artery can result in life-threatening airway obstruction. Surgical ligation under intubation or tracheostomy is the most widely used approach for controlling mouth floor bleeding in this highly vascular region. Nonetheless, surgically exploring the bleeding focus is difficult because of anatomical distortion followed by widespread edema and swelling. Since swelling of the mouth floor advances quickly, timely management is essential for favorable postoperative outcome. This paper reports a case of immediate hemorrhage control with angiographic embolization to perform rapid hemostasis before the ongoing swelling causes airway obstruction. Less invasive, angiographic embolization can prevent neurovascular damage during a surgical exploration of injured vascular structures on the mouth floor.

Objective : Endovascular treatment of wide-necked intracranial aneurysms is a challenge and the durability and the safety of these treated aneurysms remain unknown. The aim of this study was to evaluate the clinical and long-term angiographic results of wide-necked intracranial aneurysms treated with coil embolization. Methods : Between January 2002 and December 2012, 53 wide-necked aneurysms treated with coil embolization were selected. Forty were female, and 13 were male. Twenty eight (52.8%) were ruptured aneurysms, and 25 (47.2%) were unruptured aneurysms. The patents' medical and radiological records were reviewed retrospectively. Results : Of the 53 aneurysms, coiling alone was employed in 45 (84.9%) and stent-assisted coiling was done in 8 (15.1%). The initial angiographic results revealed Raymond class 1 (complete occlusion) in 30 (56.6%) cases, Raymond class 2 (residual neck) in 18 (34.0%) cases, and Raymond class 3 (residual sac) in 5 (9.4%) cases. The mean angiographic follow-up period was 37.9 months (12-120 months). At the last angiographies, Raymond class 1 was seen in 26 (49.1%) cases, Raymond class 2 in 16 (30.2%), and Raymond class 3 in 11 (20.8%). Angiographic recurrence occurred in 22 (41.5%) patients, with minor recurrence in 7 (13.2%) cases and major recurrence in 15 (28.3%). Retreatment was performed in 8 cases (15.1%). A suboptimal result on the initial angiography was a significant predictor of recurrence in this study (p=0.03). Conclusion : The predictor of recurrence in wide-necked aneurysms is a suboptimal result on the initial angiography. Long-term angiographic follow-up is recommended in wide-necked aneurysms.

Purpose: Hemodynamically unstable pelvic fractures represent therapeutic challenges for the trauma team. The authors of this article have studied the clinical profiles of the angiographic intervention population at the emergency department during four years (2005~2009) to develop clinical guidelines for preventing deaths due to multiple trauma and for predicting the prognosis during initial evaluation. Methods: We performed a retrospective review of 34 patients who had undergone angiographic interventions at the emergency department and compared the differences in clinical variables between survivors and non-survivors. Results: Representative values were compared between survivors and non-survivors : RTS (revised trauma score) 7.006 (6.376~7.841) vs. 6.128 (4.298~6.494), PRC (packed red cell) units 5.5 (2.0~11.0) vs. 15 (8.0~18.5), and lactate (mmol/L) 3.0 (1.0~7.0) vs. 8.5 (3.5~10.5). RTS (p<0.01) and PRC units before angiographic interventions (p=0.01) and lactate (p=0.02) had correlations to the final outcomes. Conclusion: The availability of an angiographic suite and persistent hypotension after adequate fluid resuscitation for pelvic trauma are good indications of angiographic intervention for pelvic hemorrhage.

Purpose: Nowadays, non-operative management increases in patients with blunt splenic injury due to development of diagnostic and interventional technique. The purpose of this study is to evaluate the management in patients with blunt splenic injury and effect of clinical state such as shock on the choice of management. Methods: From April 2007 to July 2013, we retrospectively reviewed the medical charts of fifty patients who had splenic injury after blunt trauma. The demographic characteristics, American Association for the Surgery of Trauma (AAST) grade of splenic injury, management method (emergency operation, angiographic embolization or observation) and clinical outcome were analyzed. Results: The mean age was $41.5{\pm}21.4$ years and male was 44(88%). Twenty patients(40%) were in shock condition initially and five patients(10%) underwent emergency operation due to hemodynamic instability. Emergency angiographic embolization was performed in 20 patients(40%) and 25 patients were managed conservatively. When patients were divided into shock group (SG) and non-shock group (NSG), Patients in SG had significantly higher serum lactate level and base deficit than NSG (lactate; $4.5{\pm}3.4$ mmol/L, base deficit; $5.8{\pm}4.4$ mmol/L vs $1.9{\pm}1.4$ mmol/L, $2.8{\pm}2.5$ mmol/L, p=0.007, p=0.013). There was no significant difference of AAST grade and contrast blush rate in abdomen CT between two groups. Among 45 patients with non-operative management, four patients(8.9%) got delayed angiographic embolization and 3 patient died from companied organ injury. Conclusion: Non-operative management can be acceptable management option in patients with splenic blunt trauma under intensive hemodynamic monitoring.

A ruptured distal lenticulostriate artery (LSA) aneurysm is detected occasionally in moyamoya disease (MMD) patients presented with intracerebral hemorrhage. If the aneurysm is detected in hemorrhage site on angiographic evaluation, its obliteration could be considered, because it rebleeds frequently, and is associated with poorer outcome and mortality in MMD related hemorrhage. In this case report, the authors present two MMD cases with ruptured distal LSA aneurysm treated by endovascular embolization.

Purpose: Immediate identification of vascular injury requiring embolization in patients with pelvic bone fracture isn't an easy task. There have been many trials finding indicators of embolization for patients with pelvic bone fracture. Although Young and Burgess classification is useful in decision making of treatment, it is reported to have little value as indicator of embolization in major trauma patients. The aim of this study is to find out Young and burgess classification on predicting vessel injury by analzyng pelvic radiograph taken from major trauma patients with pelvic bone fracture. Methods: Among major trauma patients with injury severity scores (ISS) higher than 15 who visited our emergency room from January 2011 to June 2014, 200 patients were found with pelvic bone fracture in trauma series and thus pelvic CT angiography was taken. Setting aside patients with exclusion criteria, 153 patients were enrolled in this study for analysis of Young and Burgess classification. Results: The most common mechanism of injury was lateral compression in both groups. There was no statistical significant difference in Young and Burgess classification (p=0.397). The obturator artery was the most commonly injured artery in both groups. Six patients had more than one site of bleeding. Conclusion: Prediction of transcatheter angiographic embolization using Young and Burgess classification in severe trauma patients is difficult and requires additional studies.

Dissecting aneurysms frequently involve the vertebral arteries and their branches, but those involving the posterior inferior cerebellar artery [PICA] and not vertebral artery at all are extremely rare. We present a case of an isolated dissecting aneurysm of the PICA without involvement of vertebral artery. A 54-year-old man presented with dizziness and headache. MR imaging of the brain showed a cerebellar infarction of the left PICA territory. MR angiographic and cerebral angiographic studies revealed a dissecting fusiform aneurysm involving the left proximal PICA. Subsequently, the patient underwent GDC embolization. A postembolization angiogram demonstrated complete obliteration of the aneurysm. In this report, the treatment modalities for this rare condition is described with review of the literature.
