A 9-year-old girl visited our hospital, complaining of a rapid-growing and rigid swelling on the left posterior mandibular area. Panoramic radiograph showed a moderately defined multilocular honeycomb appearance involving the left mandibular body. CT scan revealed an expansile, multilocular osteolytic lesion and multiple fluid levels within cystic spaces. Bone scan demonstrated increased radiotracer uptake and angiography showed a highly vascularized lesion. The lesion was suspected as aneurysmal bone cyst (ABC) and preoperative embolization was performed, which minimize the extent of operation and the surgical complication. The lesion was treated by surgical curettage and lateral decortication with repositioning. No additional treatment such as a surgical reconstruction or bone graft was needed. Early diagnosis of ABC is very important and appropriate treatment should be performed considering several factors such as age, surgical complication, and possibility of recurrence.

The authors present a case of isolated dural arteriovenous fistula (DAVF) in the transverse sinus, which developed six years after microvascular decompression caused by hemifacial spasm via suboccipital craniectomy. The lesion was successfully treated by transarterial embolization using Onyx. We reviewed the related radiologic and therapeutic features of DAVF involving an isolated sinus and described the feasibility of the use of Onyx.

후복막강 출혈은 항응고 치료의 치명적 합병증일 수 있으며, 나이 및 산과력과 상관없이 난소동맥이 출혈 병소일 수 있다. 저자들은 폐경기 여성에서 항응고 치료 중에 발생한 난소동맥 출혈을 경도관 혈관조영술 및 색전술을 통해 정확한 진단 및 효과적인 지혈이 가능했던 증례를 소개하고자 한다.

Pulmonary arteriovenous malformations (AVMs) are caused by abnormal vascular communications between the pulmonary arteries and pulmonary veins, which lead to the blood bypassing the normal pulmonary capillary beds. Pulmonary AVMs result in right-to-left shunts, resulting in hypoxemia, cyanosis, and dyspnea. Clinical signs and symptoms vary depending on the size, number, and flow of the AVMs. Transcatheter embolization is the treatment of choice for pulmonary AVMs. However, this method can fail if the AVM is large or has multiple complex feeding arteries. Surgical resection is necessary in those kind of cases. Here, we report the case of a patient with a 6-cm pulmonary AVM with multiple feeding arteries that was successfully treated by repeated coil embolization without surgery.

With improving survival of children with complex congenital heart disease (CCHD), postoperative complications, like protein-losing enteropathy (PLE) are increasingly encountered. A 3-year-old girl with surgically corrected CCHD (ventricular inversion/L-transposition of the great arteries, ventricular septal defect, pulmonary atresia, postdouble switch procedure [Rastelli and Glenn]) developed chylothoraces. She was treated with pleurodesis, thoracic duct ligation and subsequently developed chylous ascites and PLE (serum albumin ${\leq}0.9g/dL$) and was malnourished, despite nutritional rehabilitation. Lymphangioscintigraphy/single-photon emission computed tomography showed lymphatic obstruction at the cisterna chyli level. A segmental chyle leak and chylous lymphangiectasia were confirmed by gastrointestinal endoscopy, magnetic resonance (MR) enterography, and MR lymphangiography. Selective glue embolization of leaking intestinal lymphatic trunks led to prompt reversal of PLE. Serum albumin level and weight gain markedly improved and have been maintained for over 3 years. Selective interventional embolization reversed this devastating lymphatic complication of surgically corrected CCHD.

Posttraumatic pseudoaneurysms of the sphenopalatine artery are rare. Only a few cases have been reported. We report two cases of hemorrhage due to pseudoaneurysm of the sphenopalatine artery. The hemorrhage was uncontrollable. It required embolization. Two patients visited our hospital for treatment of zygomaticomaxillary complex fracture. At the emergency room, patients presented with massive nasal bleeding which ceased shortly. After reduction of the fracture, patients presented persistent nasopharyngeal bleeding. Under suspicion of intracranial vessel injury, we performed angiography. Angiograms revealed pseudoaneurysms of the sphenopalatine artery. Endovascular embolization was performed, leading to successful hemostasis in both patients. Due to close proximity to pterygoid plates, zygomaticomaxillary complex fracture involving pterygoid plates may cause injury of the sphenopalatine artery. The only presentation of sphenopalatine artery injury is nasopharyngeal bleeding which is common. Based on our clinical experience, although pseudoaneurysm of maxillary artery branch after maxillofacial trauma has a low incidence, suspicion of injury involving deeply located arteries and early imaging via angiogram are recommended to manage recurrent bleeding after facial trauma or surgery.

Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment. Early management usually includes leg elevation, drainage, and pressure dressing. However, these methods are associated with prolonged recovery and high recurrence rates. We report a case of lymphorrhea from a calf wound after endoscopic great saphenous vein (GSV) harvesting for coronary artery bypass grafting (CABG). The patient presented with intractable oozing from the postoperative wound on the right calf. Lymphorrhea persisted for 6 weeks despite negative-pressure wound therapy with a long-acting somatostatin. We performed unilateral pedal lymphangiography that confirmed wound lymphorrhea, followed by glue embolization. No recurrence was observed after 8 months of follow-up. This case report demonstrates the successful use of lymphangiography with glue embolization in the control of lymphorrhea after GSV harvesting for CABG.

하장간막동맥은 산후출혈의 매우 드문 출혈 혈관이다. 저자들은 질분만 후 하장간막동맥에서 출혈이 있었던 일차성 산후출혈 두 개의 증례를 보고한다. 두 환자 모두 저혈량성 쇼크의 징후를 보이고 있었고, 파종성혈관내응고가 의심되는 상태였다. 산후출혈의 흔한 출혈 혈관인 자궁동맥을 색전한 후에도 출혈은 지속되었다. 하장간막동맥 혈관조영술에서 상직장동맥으로부터 조영제의 혈관외누출이 확인되어 N-butyl cyanoacrylate를 이용한 선택적 색전술을 시행하였다. 이 증례를 통해 산도 손상에 의한 산후출혈이 조절되지 않고 지속될 때 하장간막동맥이 출혈 동맥일 수 있다는 점을 강조하고자 한다.

목적: 천골 및 골반골에 발생한 거대세포종에 대한 동맥 색전술의 효용성을 규명하고자 하였다. 대상 및 방법: 1996년 12월부터 2008년 5월까지 연속적 동맥 색전술을 시행한 9예를 대상으로 그 임상 결과 및 동맥 색전술에 대한 거대세포종의 치료 반응성을 후향적으로 분석하였다. 결과: 9예 중 6예에서 거대세포종이 진행되어 연속적 동맥 색전술은 천골 및 골반골 거대세포종 치료에 있어서 효과적인 치료 방법은 아닌 것으로 나타났다. 5예의 경우에서는 수술, 방사선 치료 등의 추가적인 치료를 시행 했음에도 불구하고 거대세포종이 진행되었다. 9예 중 3예에서 거대세포종의 호전 및 완치 소견을 보여, 카이제곱 검정을 통해 이와 관련된 인자들에 대해 분석하였다. 첫 혈관조영술 시행 시 거대세포 종양의 영양 혈관수가 6개 미만인 경우(p=0.048), 측부 순환의 개수가 3개 미만인 경우(p=0.048) 만이 동맥 색전술에 대한 치료 반응성과 연관이 있는 것으로 나타났으며, 첫 동맥 색전술 시행 후 잔존 종양 염색 유무와 반복 시행 횟수는 연관이 없었다. 결론: 천골 및 골반골 거대세포종의 치료에 있어서 연속적 동맥 색전술은 일반적으로 사용될 수 있는 효과적인 치료 방법은 아니나, 첫 혈관 조영술 시행 시 종양의 혈관 분포가 적은 경우에 한해서 시행한 다면 좋은 치료 결과를 기대할 수 있다.

Purpose: This study was conducted to evaluate the effectiveness of the treatment strategy of transcatheter arterial embolization after pelvic CT angiography (CTA) in cases of traumatic pelvic hemorrhage. Methods: This is a retrospective analysis of pelvic hemorrhage patients who underwent transcatheter arterial embolization after pelvic CTA at our regional emergency center during a 31-month period. We reviewed the medical records and imagings of all these patients. Results: Transcatheter arterial embolization was performed in 17 patients (M:F=7:10, mean age=53.9) who underwent pelvic CTA for the evaluation of traumatic pelvic hemorrhage. Arterial bleeding was demonstrated on pelvic CTA in all patients, and the combined injury was also noted in 13 patients. The admission-to-CTA time was $84.53{\pm}66.92$ minutes, and the CTA-to-embolization time was $147.65{\pm}99.97$ minutes. Extravasation of contrast media or pseudoaneurysm was demonstrated on conventional angiography in all patients. Unilateral iliac artery embolization was performed in 8 patients, and bilateral iliac artery embolization was performed in 9 patients. Additional embolizations other than in the iliac arteries were performed in 7 patients. Initial hemostasis was achieved in 16 patients. One patient died of ongoing pelvic bleeding. Rebleeding occurred in only one patient and hemostasis was achieved with the second embolization. Another patient died of intracranial and facial bleeding in spite of pelvic hemostasis. The overall mortality was 11.8%, and there was no significant adverse effects in the other patients. Conclusion: Transcatheter arterial embolization after pelvic CTA is an effective treatment strategy in the management of traumatic pelvic hemorrhage patients.
