An aortic arch banding procedure was performed on an 82-year-old man for treatment of proximal type I endoleaks 2 days after he had undergone emergency thoracic endovascular aortic repair with the chimney technique for a ruptured aortic arch aneurysm. Contrast-enhanced computed tomography after the second procedure demonstrated significant shrinkage of the aneurysmal sac as well as a complete disappearance of the endoleaks. The basic concept of this technique is to treat the type IA endoleak, including possible gutter endoleaks, by creating a new proximal seal zone distal to the chimney graft using a banding technique...

Open aortic repair is considered the "gold standard" treatment for aortic occlusive disease. We present the case of an 83-year-old patient with refractory hypertension caused by paravisceral aortic stenosis including both renal arteries and the superior mesenteric artery. We planned an endovascular approach and treated the patient with parallel stent grafts in the paravisceral aorta. At 1.5 years after the operation, the patient was free of hypertensive episodes. Covered endovascular repair of the paravisceral aorta may be a valuable alternative to open aortic repair in patients unfit for open surgery...

We report renal salvage maneuvers after accidental bilateral renal artery coverage during endovascular aneurysm repair of an infrarenal abdominal aortic aneurysm. A 79-year-old man with an infrarenal abdominal aortic aneurysm was treated with endovascular aneurysm repair. Completion angiography demonstrated coverage of the renal arteries. Several revascularization techniques were attempted, including endograft repositioning and endovascular stenting through the femoral and brachial approach. The patient eventually underwent open splenorenal bypass with a Y Gore-Tex graft (W...

We report a case of infolding of a fenestrated stent graft involving the visceral vessel segment after a juxtarenal abdominal aorta aneurysm repair. The patient remains free of any significant endoleak, and the aortic sac has shown regression. The patient remains asymptomatic, with no abdominal pain, with normal renal function, and without ischemic limb complications. We hypothesize that significant graft oversizing (20%-30%) with asymmetric engineering of the diameter-reducing ties may have contributed to the infolding...

Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement...

We present a case of a 70-year-old man who was admitted with rupture of an abdominal aneurysm 4 years after endovascular aneurysm repair. He was compliant with yearly follow-up computed tomography angiography. One month earlier, his computed tomography angiogram showed perfect exclusion of the aneurysm and no endoleak. We explanted the stent graft and confirmed effective sealing, and the graft was intact. We found no signs of infection during 2 years of follow-up. This rupture is nonpredictable and unexplained and illustrates that unremarkable imaging does not guarantee prevention of rupture...

Pseudoaneurysm formation caused by iatrogenic arterial injury during a regional anesthetic block is a rare complication. We report a case of a 56-year-old male patient who developed an axillary artery pseudoaneurysm caused by brachial plexus block performed for an upper extremity dialysis access operation. Successful repair of this pseudoaneurysm was achieved with endovascular stent graft exclusion. The repaired axillary artery with the stent graft remained patent after 10 years of follow-up. The successful long-term patency of this treatment and a strategy to potentially avoid this complication are discussed...

Angulated anatomy in the aorta, such as tortuous infrarenal aortic necks or steep aortic arches, is a significant challenge for endovascular aortic repair because it often causes inadequate sealing and fixation, which may lead to treatment failure. We have developed a technique using off-the-shelf equipment to precisely control the deployment of stent grafts in challenging landing zones. The key of this technique is to create a through-and-through wire between two access sites and to use a guiding device over the wire...

A 60-year-old woman involved in a motor vehicle collision presented with a traumatic pseudoaneurysm of the innominate artery origin in addition to multiple concomitant injuries. She was classified as a high-risk candidate for open repair. An experimental thoracic branched graft device was used for coverage of the injury with the addition of a right carotid-to-left carotid-to-left subclavian artery bypass. Follow-up imaging showed resolution of the pseudoaneurysm and patency of her bypass grafts. This is the first described use of the Mona LSA Branch Thoracic Stent Graft System (Medtronic, Minneapolis, Minn) in the innominate artery...

Novel endovascular techniques hope to offer patients aortic arch repair with reduced morbidity compared to conventional arch surgery; however, current endovascular strategies remain challenged by the proximal seal zone, higher stroke rates, long-term durability and select anatomy. Hybrid arch repair offers patients a less invasive alternative that can treat more distal aorta than conventional arch repair yet still be performed via standard sternotomy. Areas Covered: This review will discuss the current evidence and future development of hybrid aortic arch and frozen elephant trunk reconstruction...

BACKGROUND: Midaortic syndrome (MAS) is a rare condition characterized by stenosis of the abdominal aorta. Patients with disease refractory to medical management will usually require either endovascular therapy or surgery with use of prosthetic graft material for bypass or patch angioplasty. We report our early experience with a novel approach using a tissue expander (TE) to lengthen the normal native arteries in children with MAS, allowing primary aortic repair without the need for prosthetic graft material...

Recently, in Japan, the J Graft Open Stent Graft (JOSG) was commercialized for surgical repair of an aortic aneurysm and aortic dissection and the frozen elephant trunk technique was applied. Kinking of the JOSG is a rare adverse event that requires additional intervention. We experienced 2 patients who developed kinking of a JOSG after translocated total arch replacement with the frozen elephant trunk technique for acute Type A aortic dissection. Both patients had intermittent claudication with a decreased ankle-brachial pressure index after the operation...

BACKGROUND: Type Ia endoleaks are not uncommon complications that occur after thoracic endovascular aortic repair (TEVAR). Because aortic arch vessels prevent extension of the landing zone, it is very difficult to manipulate a type Ia endoleak using an extension cuff or stent-graft, especially when the aortic arch is involved. Here, we retrospectively review our experience of surgical treatment of type Ia endoleak after TEVAR using a stented elephant trunk procedure. METHODS: From July 2010 to August 2016, we treated 17 patients diagnosed with a type Ia endoleak following TEVAR using stented elephant trunk procedure...

In Behçet's disease (BD) patients, endovascular repair is a reasonable alternative treatment for aortic aneurysms to avoid postoperative anastomotic pseudoaneurysms. However, there are some complications that may occur after endovascular repair. We herein report the case of a 40-year-old man with active BD developed recurrent aortic pseudoaneurysms at the proximal and distal margins of the stent graft and a femoral puncture site pseudoaneurysm 3 months after endovascular abdominal aortic aneurysm (AAA) repair...

Endovascular stent graft repair has become a common treatment for complicated Stanford Type B aortic dissection in order to restore true lumen flow and induce false lumen thrombosis. Using computational fluid dynamics, this study reports the differences in flow patterns and wall shear stress distribution in complicated Stanford Type B aortic dissection patients after endovascular stent graft repair. Five patients were included in this study: two having more than 80% false lumen thrombosis (Group 1), while three others had less than 80% false lumen thrombosis (Group 2) within one year following endovascular repair...

BACKGROUND: Long segment occlusive disease in the superficial femoral artery remains a treatment challenge despite advances in open surgical and endovascular approaches. We report initial clinical results of an entirely new procedure to perform femoropopliteal bypass using the DETOUR System to create a stentgraft bypass which originates in the SFA, travels through the femoral vein, and ends in the popliteal artery, bypassing the diseased segment. METHODS: Review the initial results of the first five patients at a single site enrolled in IRB-approved, prospective clinical study using the DETOUR System...

The advancement of endovascular therapy has led to minimally invasive solutions to increasingly complex aortic pathology, including thoracoabdominal aneurysms and those involving the visceral segment. Upper extremity access is beneficial in a variety of these complex interventions, and may be absolutely required for certain procedures such as placement of parallel chimney grafts. Traditionally, the brachial artery has been the primary access site on the arm, using either a percutaneous or open approach. Brachial access is safe and effective, and remains suitable for the majority of clinical situations...
