Use of the Pipeline embolization device (PED) has increased based on studies about its safety and effectiveness, and new reports that describe perior postprocedural complications are now emerging. We report a rare periprocedural device-related complication that occurred during endovascular treatment with the pipeline embolization device for a dissecting aneurysm on the vertebral artery. A 55-year old woman was admitted due to left medullary infarction, and angiography showed a fusiform dilatation in the left vertebral artery that was suspicious for dissecting aneurysm. Endovascular treatment with PED was planned. Under general anesthesia, the procedure was performed without significant problems and a PED was deployed in an appropriate position. However, in the final step of the procedure, the distal tip of the PED delivery wire became engaged within a small branch of the posterior cerebral artery and fractured. Fortunately, imaging studies after the procedure revealed neither hemorrhagic nor ischemic stroke, and the patient recovered without neurological morbidities except initial symptoms.

신성 고혈압은 소아기 이차성 고혈압의 흔한 원인이며, 그 중 신동맥 협착은 치료 가능한 고혈압의 가장 흔한 원인이다. 신혈관성 고혈압 치료로 약물치료에 반응하지 않는 경우 혹은 초기 단계부터 치료목적으로 경피적 혈관 성형술과 신장동맥 스텐트 등의 중재적 혈관 성형술이나 수술요법이 시행할 수 있다. 죽상 경화형 협착, 다발성의 협착, 미세동맥류, 그리고 협착 부위가 혈관 성형술이나 stent로 교정되기 어려운 경우에는 부분적 혹은 완전 신장동맥 색전술이 시도될 수 있다. 저자들은 신장동맥 색전술을 이용한 renal ablation요법으로 고혈압의 호전을 보인 신혈관 고혈압증 1례를 경험하였기에 보고하는 바이다.

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.

Treatment of paraclinoid aneurysms weather by surgery, or endovascular embolization has a risk of visual loss due to optic neuropathy, or diplopia due to cranial nerve palsies. Visual complications occur immediately after the clipping, whereas they can occur variable time after endovascular coiling. Recently, endovascular coiling for paraclinoid aneurysm is regarded as a safe and feasible treatment. But it still has risks of acute thromboembolic complication, or cranial nerve palsies. A 45-year-old woman was referred from local hospital to our hospital due to ruptured large ICA dorsal wall aneurysm. A total of 12 coils (195 cm) were used for obliteration of aneurysm. Postoperative diffusion weighted image showed no abnormal signal intensity lesion and magnetic resonance angiography demonstrated no sign of vasospasm, or vessel narrowing. But, she complained visual problem 23 days after coil embolization. Ophthalmologist confirmed the left optic disc atrophy on fundoscopy. Although steroid was started, but monocular blindness did not recover completely. The endovascular embolization of paraclinoid aneurysm, especially projecting superiorly with large irregular shape, has the risk of progressive visual loss because of the proximity to optic nerve.

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.

Objective : Cerebral aneurysms which cause oculomotor nerve [cranial nerve (CN) III] palsy, are frequently found with a daughter sac of the aneurysm dome. We assumed that CN III might be compressed by the daughter sac and it would be more helpful not to fill the daughter sac with coils than vice versa during endosaccular embolization for recovering from CN III palsy, because it may give a greater chance for the daughter sac to shrink by itself later. We reviewed the initial results of our experiences of such cases. Methods : Among 9 aneurysms accompanied by CN III palsy, 7 (6 unruptured, 1 ruptured) showed a daughter sac. We tried to fill the main dome completely and spare the daughter sac from coil filling to increase the possibility of decompression. We evaluated the short-term effectiveness of this concept using medical records and angiograms. Results : After initial embolization, all of CN III palsy caused by unruptured aneurysms (6/6) resolved completely after various periods (3-90 days) of time. No adverse effects were noted during and after the procedures except for one case of harmless coil stretching during coil filling using double microcatheter. Conclusion : During the coil embolization of the cerebral aneurysm causing CN III palsy, sparing the daughter sac from coil packing while tightly packing the main dome, can be helpful in increasing the effectiveness of decompression. However, a long-term follow-up will be required.
