Objective : The purpose of this study was to report the morbidity, mortality, angiographic results, and merits of elective coiling of unruptured intracranial aneurysms. Methods : Ninety-six unruptured aneurysms in 92 patients were electively treated with detachable coils. Eighty-one of these aneurysms were located in the anterior circulation, and 15 were located in the posterior circulation. Thirty-six aneurysms were treated in the presence of previously ruptured aneurysms that had already undergone operation. Nine unruptured aneurysms presented with symptoms of mass effect. The remaining 51 aneurysms were incidentally discovered in patients with other cerebral diseases and in individuals undergoing routine health maintenance. Angiographic and clinical outcomes and procedure-related complications were analyzed. Results : Eight procedure-related untoward events (8.3%) occurred during surgery or within procedure-related hospitalization, including thromboembolism, sac perforation, and coil migration. Permanent procedural morbidity was 2.2%; there was no mortality. Complete occlusion was achieved in 73 (76%) aneurysms, neck remnant occlusion in 18 (18.7%) aneurysms, and incomplete occlusion in five (5.2%) aneurysms, Recanalization occurred in 8 (15.4%) of 52 coiled aneurysms that were available for follow-up conventional angiography or magnetic resonance angiography over a mean period of 13.3 months. No ruptures occurred during the follow-up period (12-79 months). Conclusion : Endovascular coil surgery for patients with unruptured intracranial aneurysms is characterized by low procedural mortality and morbidity and has advantages in patients with poor general health, cerebral infarction, posterior circulation aneurysms, aneurysms of the proximal internal cerebral artery, and unruptured aneurysms associated with ruptured aneurysm. For the management of unruptured aneurysms, endovascular coil surgery is considered an attractive alterative option.

Isolated iliac artery aneurysm (IAA) is rare, but can be fatal. Emergency surgery is performed in cases of hemorrhagic shock due to a suddenly ruptured IAA, which may have a high mortality rate because of massive non-compressible torso hemorrhage (NCTH). Recently, resuscitative endovascular balloon occlusion of the aorta (REBOA) has been accepted as an alternative to aortic cross-clamping via open thoracotomy to achieve hemostasis in trauma patients with profound shock due to NCTH and is considered an emerging bridging therapy for damage control. However, there is limited information on the use of REBOA in non-trauma patients with shock. Herein, we describe a patient with impending cardiac arrest due to isolated ruptured IAA, in whom perioperative bleeding was successfully controlled by REBOA.

Aortoesophageal fistula (AEF) is a rare and potentially fatal disease that causes massive gastrointestinal bleeding. Therefore, early diagnosis and treatment are essential to prevent mortality. Controlling the massive bleeding is the most important aspect of treating AEF. The traditional surgical treatment was emergent thoracotomy, but intraoperative or perioperative mortality was high. We report a case of a patient presenting with hematemesis who was successfully treated by a staged treatment, in which bridging thoracic endovascular aortic repair was followed by delayed surgical repair of the esophagus and aorta.

The incidence of vertebral artery injury during the anterior approach to the cervical spine is rare, but potentially lethal. The authors describe two cases of vertebral artery injury during anterior cervical decompression surgery. In the first case, infection was the cause of the vertebral artery injury. During aggressive irrigation and pus drainage, massive bleeding was encountered, and intraoperative direct packing with hemostatic agents provided effective control of hemorrhage. Ten days after surgery, sudden neck swelling and mental deterioration occurred because of rebleeding from a pseudoaneurysm. In the second case, the vertebral artery was injured during decompression of cervical spondylosis while drilling the neural foramen. After intraoperative control of bleeding, the patient was referred to our hospital, and a pseudoaneurysm was detected by angiography four days after surgery. Both pseudoaneurysms were successfully occluded by an endovascular technique without any neurological sequelae. Urgent vertebral angiography, following intraoperative control of bleeding by hemostatic compression in cases of vertebral artery injury during anterior cervical decompression, should be performed to avoid life-threatening complications. Prompt recognition of pseudoaneurysm is mandatory, and endovascular treatment can be life saving.

Objective : The goal of this study was to document the influence of the treatment modality(surgery versus endovascular treatment) on the development of chronic shunt-dependent hydrocephalus in a series of 296 patients treated after aneurysmal subarachnoid hemorrhage(SAH). Methods : The following parameters were retrospectively analyzed for association with chronic shunt-dependent hydrocephalus : 1) Age and Sex, 2) Hunt and Hess grade, 3) Fisher computed tomographic grade, 4) aneurysm location, and 5) treatment modality(surgery versus endovascular treatment). Results : Thirty-six of 251 patients(14.3%) who survived the SAH and its neurological and/or medical sequelae underwent definitive shunting for treatment of chronic hydrocephalus. The rate of shunt dependency was positively correlated with a higher age, a higher Hunt and Hess grade, a higher Fisher computed tomographic grade, and aneurysms arising at the anterior communicating artery(p<0.05). Conclusion : The results of the present study indicate that the treatment modality used does not affect the risk of the later development of chronic shunt-dependent hydrocephalus(surgery, 16.2% [25 of 154] ; endovascular treatment, 11.3% [11 of 97] ; p=0.45).

Herein, we report the case of a 60-year-old man, a smoker with a history of arterial hypertension and diabetes mellitus. After computed tomography (CT) for an episode of hemoptysis, the patient underwent elective thoracic endovascular aortic repair (TEVAR) because of a degenerative aneurysm of the descending thoracic aorta. The area of perianeurysmal pulmonary atelectasis reported on the CT scan was not considered. Three months later, he developed an aortopulmonary fistula without endoleaks. Although TEVAR is a relatively safe procedure, no detail should be overlooked in the preoperative evaluation in order to avoid life-threatening complications. Further, the effectiveness and modality of prolonged antibiotic prophylaxis and/or preoperative respiratory physiotherapy should be assessed in such cases.

경추 수술 중 발생한 척추 동맥 손상은 드물지만 중요하다. 중재적 혈관내 치료 기술의 발전으로 척추 동맥 손상에 대한 치료 접근 방식이 바뀌었지만 확립된 치료 방침은 아직 없다. 우리는 트리플 스텐트 시술 실패 후 플러그 앤 패치 방식으로 혈관내 코일 시술을 하여 척추 동맥 손상으로 인한 가동맥류를 성공적으로 치료한 사례를 보고하고자 한다.

We report a case of successful endovascular treatment of a pseudoaneurysm and the obstruction of an aorto-aortic bypass graft, which had been performed to treat Takayasu's arteritis fifteen years prior, at the thoracic aorta. Along with the immediate relief of proximal hypertension that had caused severe heart failure, the successful exclusion of the pseudoaneurysm and the patency of the stem graft were maintained three years after the procedure.

Damage control surgery (DCS) is an abbreviated laparotomy procedure that focuses on controlling bleeding to limit the surgical insult. It has become the primary treatment modality for patients with exsanguinating truncal trauma. Herein, we present the case of a 47-year-old woman with liver, kidney, and superior mesenteric vein (SMV) injuries caused by a motor vehicle collision. The patient underwent DCS following resuscitative endovascular balloon occlusion of the aorta (REBOA). In this case report, we discuss the importance of priority setting in DCS for the treatment of multisystem damage of several abdominal organs, particularly when the patient has incurred a combination of major vascular injuries. We also discuss the implications of damage control of the SMV, perihepatic packing, and right-sided medial visceral rotation. Further understanding of DCS, along with REBOA as a novel resuscitation strategy, can facilitate the conversion of uniformly lethal abdominal injuries into rescuable injuries.

Aortic dissection caused by blunt trauma is a rare injury that can be complicated by malperfusion syndrome resulting from obstruction of branch vessels of the aorta. Here, we present a case of traumatic type B aortic dissection with right renal and small bowel ischemia, successfully managed by endovascular fenestration.
