We report a case of concurrent saccular aneurysms caused by a penetrating atherosclerotic ulcer of the thoracic and abdominal aorta that were successfully treated by staged endovascular repair. Even though surgical open repair or endovascular repair is the treatment option, use of endovascular repair is now accepted as an alternative treatment to surgery in selected patients. To prevent contrast medium-induced nephropathy and spinal cord ischemia caused by a simultaneous endovascular procedure, a saccular aneurysm of the descending thoracic aorta was excluded by stent graft, followed by the placement of a bifurcated stent graft in the infrarenal abdominal aorta one month later.

Extracranial carotid artery dissection may manifest as arterial stenosis or occlusion, or as dissecting aneurysm formation. Anticoagulation and/or antiplatelet therapy is the first-line treatment, but because it is effective and less invasive than other procedures, endovascular treatment of carotid artery dissection has recently attracted interest. We encountered two consecutive cases of trauma-related extracranial internal carotid artery dissection, one in the suprabulbar portion and one in the subpetrosal portion. We managed the patient with suprabulbar dissection using a self-expandable metallic stent and managed the patient with subpetrosal dissection using a balloon-expandable metallic stent. In both patients the dissecting aneurysm disappeared, and at follow-up improved luminal patency was observed.

스텐트 그라프트를 이용한 대동맥류에 대한 혈관내 치료는 급격히 발전하고 있다. 저자들은 대동맥궁 탈분지술 후 스텐트 그라프트를 설치한 hybrid TEVAR (thoracic endovascular aortic repair) 1예에 대해 보고하고자 한다. 환자는 2년 반 전 Type I 급성 대동맥 박리로 상행 대동맥 치환술을 시행하였다. 수술 후 박리 원위부의 동맥류성 변화가 점차 진행하여 이에 대한 치료로 먼저 상행 대동맥으로 부터 무명동맥과 좌경동맥으로 향하는 우회로를 만든 다음 전향적으로 대동맥궁 전체 및 근위부 하행 흉부 대동맥에 걸쳐 스텐트 그라프트를 설치하였다.

Objective : Paraclinoid aneurysms are a group of aneurysms arising at the distal internal carotid artery. Due to a high incidence of small, wide-necked aneurysms in this zone, it is often challenging to achieve complete occlusion when solely using detachable coils, thus stent placement is often required. In the present study, we aimed to investigate the effect of stent placement in endovascular treatment of paraclinoid aneurysms. Methods : Data of 98 paraclinoid aneurysms treated by endovascular approach in our center from August 2005 to June 2016 were retrospectively reviewed. They were divided into two groups : simple coiling and stent-assisted coiling. Differences in the recurrence and progressive occlusion between the two groups were mainly analyzed. The recurrence was defined as more than one grade worsening according to Raymond-Roy Classification or major recanalization that is large enough to permit retreatment in the follow-up study compared to the immediate post-operative results. Results : Complete occlusion was achieved immediately after endovascular treatment in eight out of 37 patients (21.6%) in the stent-assisted group and 18 out of 61 (29.5%) in the simple coiling group. In the follow-up imaging studies, the recurrence rate was lower in the stent-assisted group (one out of 37, 2.7%) compared to the simple coiling group (13 out of 61, 21.3%) (p=0.011). Multivariate logistic regression model showed lower recurrence rate in the stent-assisted group than the simple coiling group (odds ratio [OR] 0.051, 95% confidence interval [CI] 0.005-0.527). Furthermore there was also a significant difference in the rate of progressive occlusion between the stent-assisted group (16 out of 29 patients, 55.2%) and the simple coiling group (10 out of 43 patients, 23.3%) (p=0.006). The stent-assisted group also exhibited a higher rate of progressive occlusion than the simple coiling group in the multivariate logistic regression model (OR 3.208, 95% CI 1.106-9.302). Conclusion : Use of stents results in good prognosis not only by reducing the recurrence rate but also by increasing the rate of progressive occlusion in wide-necked paraclinoid aneurysms. Stent-assisted coil embolization can be an important treatment strategy for paraclinoid aneurysms when considering the superiority of long term outcome.

This 58-year-old woman was transferred from a local hospital due to symptoms of acute headache and decreased consciousness. Computed tomography revealed a subarachnoid hemorrhage with blood clot in prepontine cistern. On the first day in the hospital, diagnostic cerebral angiography revealed a basilar tip aneurysm. We performed basilar artery to bilateral posterior cerebral artery[PCA] stent placement to reconstruct the basilar artery apex.

저자들은 복부 대동맥에 발생한 동맥-요관루를 혈관 내 접근을 통해 성공적으로 치료할 수 있었던 드문 증례를 보고하는 바이다. 동맥-요관루는 극히 드물지만, 사망률이 7~23%에 이르는 치명적인 질환이다. 저혈량쇼크와 같은 치명적 합병증을 예방하기 위해서는 조기 진단과 함께 즉각적인 치료가 필수적이다. 하지만 질환 자체가 희귀하고 민감도가 높은 검사 방법이 없기 때문에, 진단을 위해서는 높은 수준의 임상적 의심이 반드시 필요하다. 복강 내 수술, 방사선 치료 및 요관 스텐트의 장기 설치 등의 특징적인 과거력을 가진 환자에서 외상적 사건이 동맥-요관루 발생의 촉발 요인이 될 수 있다. 복부 대동맥에 발생한 동맥-요관루 환자에서도 혈관 내 인조혈관 스텐트의 삽입은 효과적인 치료 방법이다.

Central venous cannulation is one of the most commonly performed procedures for critically ill patients in the emergency room. Serious complications like a rupture of subclavian artery may occur during this procedure. We report a case of successful stent graft deployment for iatrogenic ruptured subclavian artery after attempted right subclavian vein catheterization in a 31 year-old female patient with hypovolemic shock due to cervical os laceration during vaginal delivery.

Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treatment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was successfully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

The surgical as well as endovascular treatment of blood-blister-like aneursysms (BBAs) is extremely difficult because of these pathological natures, such as small and the fragile necks. The optimal treatment of BBAs has remained uncertain. Stents are known to divert blood flow and induce thrombosis of intracranial aneurysms. We report 3 cases of successful obliteration of BBAs after multiple stents placement.

A 44-year-old woman presented with recurrent, transient episodes of left-side hemiparesis. She had received a radiation dose of 6120 cGy to her cervical region for parotid gland carcinoma 13 years previously. Cerebral angiography revealed a long, irregular tight stenosis involving the right extracranial internal carotid artery [ICA] and common carotid artery [CCA], measuring approximately 90% at the most severe narrowing according to North American Symptomatic Carotid Endarterectomy Trial criteria. Endovascular stent placement resulted in restoration of the carotid lumen to about 80% of its original diameter. She showed no further ischemic events during the follow-up period of 48 months. Our clinical and angiographic findings suggest that carotid stenting is considered a safe and effective treatment option in patients with radiation-induced carotid stenosis.
