  • The usual treatment for aortic aneurysms is surgical replacement with a prosthetic graft; however the associated morbidity and mortality rates must be considered. Endovascular placement of self-expandable stent-graft is a safe noninvasive treatment that can be an alternative to the surgical repair, the postoperative course of the 2 cases of thoracoabdominal aortic aneurysms was uneventful and no complication has been associated with the stent-graft during the 17 months and 5 months follow-up studies,.

  • Acute complicated type B aortic dissection (TBAD) is a potentially catastrophic, life-threatening condition. If left untreated, there is a high risk of aortic rupture, irreversible organ or limb damage, or death. Several risk factors have been associated with acute complicated TBAD, including age and refractory hypertension. In the acute phase, even uncomplicated patients are more prone to develop complications if hypertension and pain are left medically untreated. Innovations in stent graft technologies have incrementally improved outcomes since their first use for this condition in 1999, though improvement is needed in mitigating periprocedural complications, adverse events, and mortality. In the past decade, endovascular repair has become the preferred treatment because of its superior outcomes to open repair and medical therapy. The Valiant Captivia Thoracic Stent Graft System is a third-generation endovascular stent graft with advancements in minimally invasive delivery, conformability to the anatomy, and the minimization of adverse sequelae. Herein, this stent graft is briefly reviewed and its 3-year outcomes are presented. Freedom from all-cause and dissection-related mortality was 79.1% and 90.0%, respectiv ely. The Valiant Captiv ia Stent Graft represents a safe, effective intervention for acute complicated TBAD. Continued surveillance is needed to verify its longer-term durability.

  • Hemorrhage after pancreaticobiliary surgery is an infrequent but fatal complication. It is primarily caused by rupture of the pseudoaneurysm, and treatment options include endovascular coil embolization or endovascular stent-graft placement. Herein, we report a case of migration of an arterial stent-graft that was placed in the common hepatic artery to treat pseudoaneurysm after pylorus-preserving pancreaticoduodenectomy. The stent-graft migrated to the jejunum and was eventually excreted from the body.

  • Detachable balloon-based endovascular fistula occlusion is a widely accepted treatment for traumatic carotid cavernous fistulas (CCF). However, more recently coils have been used to obliterate the lesion, especially in case detachable balloon is not available. We failed balloon-assisted coil embolization for CCF because of large fistulas and herniation of coil loops into the parent artery. The authors describe our experiences of balloon-expandable graft-stents to treat CCF, and place emphasis on arterial wall reconstruction. Three traumatic CCF patients were treated using a graft-stent with/without coils, and underwent angiographic follow-up to evaluate the patency of the internal carotid artery (ICA). In all cases, symptoms related to CCF regressed after stent deployment and did not recur during follow-up. Follow-up angiography revealed good patency of the ICA in all patients. Graft-stents should be considered as an alternative means of treating CCF and preserving the parent artery by arterial wall reconstruction especially in patients with a fistula that cannot be successfully occluded with detachable balloons or coils.

  • The intrinsic structural failure of a Dacron graft resulting from the loss of structural integrity of the graft fabric can cause late graft complications. Late non-anastomotic rupture has traditionally been treated surgically via open thoracotomy. We report a case of the successful use of thoracic endovascular repair to treat a Dacron graft rupture in the descending aorta. The rupture occurred 20 years after the graft had been placed. Two stent grafts were placed at the proximal portion of the surgical graft, covering almost its entire length.

  • Penetrated injury of common carotid artery (CCA) is rare and extremely lethal. Carotid artery injury tends to bleed actively and potentially occlude the trachea. It can cause fatal neurological complications. An accurate diagnosis and adequate treatment are very needed to the successful outcome of the penetrating vascular injury in zone 1, 2, and 3 of the neck. Open surgical treatment is more invasive and complicated than endovascular treatment. We experienced a case with penetrating injury in neck zone 2. Here, we report the case successfully treated with endovascular stent graft technique.

Management for the Newly-Onset Aneurysmal Dilation of the Distal Aorta after an Endovascular Stent Graft Procedure for the Patient with Acute Aortic Dissection Type IIIb (급성 하행대동맥 박리증에서 스텐트-그라프트 삽입 후 새로이 발생한 원위부 대동맥류에 대한 인조혈관 대치술 치험 1예)

  • The surgical managements for the complicated aortic disease is still one of most challenging fields for the cardiac surgeons. The endovascular stent graft procedure has been tried recently to avoid serious complications caused by traditional graft replacement technique. However, indications for the procedures or management methods for the complications have not been clearly elucidated so far. We report a case of successful management for the newly-onset aneurysmal dilation of the distal aorta after an endovascular stent graft procedure in a patient with acute aortic dissection type IIIB.

  • The treatment of bilateral vertebral artery dissecting aneurysms (VADAs) presenting with subarachnoid hemorrhage (SAH) is still challenging. The authors report a rare case of bilateral VADA treated with coil trapping of ruptured VADA and covered stents implantation after multiple unsuccessful stent assisted coiling of the contralateral unruptured VADA. A 44-year-old woman was admitted to our hospital because of severe headache and sudden stuporous consciousness. Brain CT showed thick SAH and intraventricular hemorrhage. Cerebral angiography demonstrated bilateral VADA. Based on the SAH pattern and aneurysm configurations, the right VADA was considered ruptured. This was trapped with endovascular coils without difficulty. One month later, the contralateral unruptured VADA was protected using a stent-within-a-stent technique, but marked enlargement of the left VADA was detected by 8-months follow-up angiography. Subsequently two times coil packing for pseudosacs resulted in near complete occlusion of left VADA. However, it continued to grow. Covered stents graft below the posterior inferior cerebellar artery (PICA) origin and a coronary stent implantation across the origin of the PICA resulted in near complete obliteration of the VADA. Covered stent graft can be used as a last therapeutic option for the management of VADA, which requires absolute preservation of VA flow.

  • For high-risk patients, endovascular aortic aneurysm repair (EVAR) is a good option but may lead to serious complications, which should be addressed immediately. A 75-year-old man with a history of abdominal surgery underwent EVAR for an aneurysm of the abdominal aorta and iliac arteries. During EVAR, iliac artery rupture and graft limb occlusion occurred, and they were successfully managed by the additional deployment of an iliac stent graft and balloon thrombectomy, respectively. We, herein, report a rare case of the simultaneous development of the two fatal complications treated by the endovascular technique.

  • Use of endovascular stent-graft in aortic aneurysm disease is now accepted as an alternative treatment to surgery. We successfully treated two patients with high risk of thoracic aortic aneurysm with percutaneous endovascular stent-graft. Three and ten months follow up chest CT showed obliteration of aneurysm and there was no complication after stent grafting.
