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.

Muscle injuries caused by indirect trauma during exercise are common. Most of these injuries can be managed conservatively; however, further treatment is required in extreme cases. Although transcatheter arterial embolization is a possible treatment modality, its role in traumatic muscle injuries remains unclear. In this case series, we present three cases of exercise-induced muscle hemorrhage treated by transcatheter arterial embolization with successful outcomes. The damaged muscles were the rectus abdominis, adductor longus, and iliopsoas, and the vascular injuries were accessed via the femoral artery during the procedures.

Abdominal wall hematoma (AWH) after blunt trauma is common, and most cases can be treated conservatively. More invasive treatment is required in patients with traumatic AWH if active bleeding is identified or there is no response to medical treatment. Herein, we report a case of endovascular embolization for traumatic subcutaneous AWH. Almost endovascular treatment for AWH is done through the deep inferior epigastric artery. However, in this case, the superficial inferior epigastric artery was the bleeding focus and embolization target. After understanding the vascular system of the abdominal wall, an endovascular approach and embolization is a safe and effective treatment option for AWH.

Dural arteriovenous fistula (DAVF) is a rare condition affecting approximately 1.5% of 1,000,000 individuals annually. It frequently occurs in the transsigmoid and cavernous sinuses. An isolated sigmoid sinus is extremely rare and is treated by performing transfemoral transvenous embolization along the opposite transverse sinus. A 69-year-old woman presented with asymptomatic Borden type III/Cognard type III DAVF involving an isolated sigmoid sinus. She underwent a staged operation in which a navigation system was used to expose the sigmoid sinus in the operating room before transferring the patient to the angio suite for transvenous embolization. Various modalities have been used to treat DAVF, including surgical disconnection, transarterial embolization, transvenous embolization, and stereotactic radiosurgery. However, treating DAVF cases where the affected sinus is isolated can be challenging because an easily accessible surgical route may not be available. In this case, direct sinus cannulation and transvenous embolization were the most effective treatments.

False aneurysms(Pseudoaneurysms) and arteriovenous fistulas have only rarely been reported in the facial region. In this region the false aneurysm arises most frequently in the superficial temporal and facial artery, but other branches of the external carotid are sometimes involved, including the maxillary and lingual artery. False aneurysms can be occurred by blunt trauma that either laceration or rupture the full thickness of the arterial wall. The diagnosis of a false arterial aneurysm can be often made solely on the basis of physical examination. Angiography is helpful for conformation, for delineating the lesion and its vascular supply, and for ruling out the presence of associated vascular lesions such as arteriovenous fistulas. Ultrasonography may also be useful in delineating lesions that are not easily accessible for physical examination. Treatment of false aneurysms is excision, ligation, and arterial embolization. This is a case of false aneurysm of the lingual artery after facial trauma caused by traffic accident. The lesion was successfully treated by embolization and ligation of the lingual and facial branches of the external carotid artery.

Pulmonary systemic arterialization to normal basal lung without sequestration is a rare congenital anomaly. In this rare abnormality, arterialization of the left lower lobe is the most common type. In general, surgical treatments have been performed. Recently, for reducing the complications and risks of surgery, embolization is mainly attempted by using coils. We report a case of 22-year-old male patient with a 10 mm anomalous arterial supply to his normal lung, which is being successfully treated by transcatheter embolization when using the Amplatzer Vascular Plug that has been adapted for the treatment of high-flows and large artery occlusions.

Although endovascular intervention is the first-line treatment of intracranial aneurysm, intraprocedural rupture or extravasation is still an endangering event. We describe two interesting cases of extravasation during embolotherapy for ruptured peripheral cerebral pseudoaneurysms. Two male patients were admitted after development of sudden headache with presentation of intracerebral and subarachnoid hemorrhage, respectively. Initial angiographic assessment failed to uncover any aneurysmal dilatation in both patients. Two weeks afterwards, catheter angiography revealed aneurysms each in the peripheral middle cerebral artery and anterior inferior cerebellar artery. Under a general anesthesia, endovascular embolization was attempted without systemic heparinization. In each case, sudden extravasation was noted around the aneurysm during manual injection of contrast after microcatheter navigation. Immediate computed tomographic scan showed a large amount of contrast collection within the brain, but they tolerated and made an unremarkable recovery thereafter. Intraprocedural extravasation is an endangering event and needs prompt management, however proximal plugging with coil deployment can be sufficient alternative, if one confronts with peripheral pseudoaneurysm. Peculiar angiographic features are deemed attributable to extremely fragile, porous vascular wall of the pseudoaneurysm. Accordingly, it should be noted that extreme caution being needed to handle such a friable vascular lesion.

Arteriovenous malformations (AVMs) are characterized by the presence of abnormal connections between feeding arteries and draining veins. It is generally assumed that symptomatic lesions can preferably be treated. Due to high arterial blood flow, there is a risk of bleeding with surgical excision alone, which can be massive and life threatening during the operation. According to recent advances in interventional technique, a hybrid approach using embolization of the feeding artery with subsequent immediate excision of the AVM for successful management of vascular lesions could be applied to AVMs. Herein, we describe a case of successful excision of AVM in the left soleus muscle using a hybrid approach.

Pulmonary arteriovenous malformation (PAVM) is a rare anomalous direct communication between the pulmonary artery and vein with a considerable risk of serious complications such as cerebral thromboembolism or abscess and pulmonary hemorrhage. Although the past, surgical resection such as lobectomy was mostly used to treat PAVM, the recent development of endovascular treatment has made it a primary consideration to perform transcatheter embolization using coils or detachable balloons. We report a case of successful transcatheter embolization of giant PAVM with the second generation Amplatzer vascular plug II as a new self-expanding device.

The spinal dural arteriovenous fistula (SDAVF) is rare, presenting with progressive, insidious symptoms, and inducing spinal cord ischemia and myelopathy, resulting in severe neurological deficits. If physicians have accurate and enough information about vascular anatomy and hemodynamics, they achieve the good results though the surgery or endovascular embolization. However, when selective spinal angiography is unsuccessful due to neurological deficits, surgery and endovascular embolization might be failed because of inadequate information. We describe a patient with a history of vasospasm during spinal angiography, who was successfully treated by spinal stereotactic radiosurgery using Novalis system.
