Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin access (9/25; 36%) were managed through the percutaneous remote access...

Heritable thoracic aortic aneurysms and dissections (TAAD), including Marfan syndrome (MFS), currently lack a cure, and causative mutations have been identified for only a fraction of affected families. Here we identify the metalloproteinase ADAMTS1 and inducible nitric oxide synthase (NOS2) as therapeutic targets in individuals with TAAD. We show that Adamts1 is a major mediator of vascular homeostasis, given that genetic haploinsufficiency of Adamts1 in mice causes TAAD similar to MFS. Aortic nitric oxide and Nos2 levels were higher in Adamts1-deficient mice and in a mouse model of MFS (hereafter referred to as MFS mice), and Nos2 inactivation protected both types of mice from aortic pathology...

Marfan syndrome (MFS) is an autosomal dominant connective tissue disease associated with acute aortic dissection (AAD). We used 2 large registries that include patients with MFS to investigate possible trends in the chronobiology of AAD in MFS. We queried the International Registry of Acute Aortic Dissection (IRAD) and the Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) registry to extract data on all patients with MFS who had suffered an AAD. The group included 257 patients with MFS who suffered an AAD from 1980 to 2012...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

Endovascular surgery represents a minimally invasive procedure for the treatment of occlusive and aneurysmal arterial disease. However, it is followed by inflammatory response, with a rise in specific inflammatory biomarkers, such as C-reactive protein, serum amyloid A and fibrinogen. Shear stress during balloon inflation and vascular injury represents triggering events for the inflammatory process, stimulating the production of proinflammatory molecules and activation of circulating monocytes. The current literature indicates that stent implantation induces more prominent inflammatory reaction...

We conducted this study to determine the risk of transmission of Q fever to health care workers (HCWs) during perioperative exposure to Coxiella burnetii-infected thoracic endovascular aneurysm stent graft. Pre-operative and 6-week post-operative phase I and II IgG Q fever antibody titers were determined in 14 staff members of an operation room. The room had a negative pressure and all the members of the surgical team wore either a fitted N-95 mask or a powered purified air respirator. Phase I and II IgG antibody titers were <1:16 for 11 of the 14 studied HCWs; 2 HCWs did not follow up at 6 weeks and 1 had a pre-exposure phase II IgG titer of 1:128 with no change 6 weeks later...

A 56-year-old female patient was transferred due to the presence of a left supraclavicular pulsatile mass. Further work-up was performed to confirm diagnosis. Angiography and computed tomography were also performed. The anatomy of the thoracic aorta suggested an unknown and untreated aortic coarctation. A second aortic narrowing was identified at the aortic arch, a result of elongation of the aorta. Endovascular approach was not possible, due to complexity of the aortic anatomy, and tortuosity. Open surgical repair was successfully performed...

OBJECTIVES: To quantify the impact of thoracic endovascular aortic repair (TEVAR) on radial aortic strain with the aim of elucidating stent-graft-induced stiffening and complications. METHODS: Twenty fresh thoracic porcine aortas were connected to a mock circulatory loop driven by a centrifugal flow pump. A high-definition camera captured diameters at five different pressure levels (100, 120, 140, 160, and 180 mmHg), before and after TEVAR. Three oversizing groups were created: 0-9% (n = 7), 10-19% (n = 6), and 20-29% (n = 6)...

OBJECTIVES: We aimed to develop a simple, reliable, and timesaving technique for the therapy of thoracoabdominal aortic (TAA) aneurysms that are not suitable for endovascular repair. METHODS: In this pilot study, we sought to combine the advantages of classic open vascular procedure with the use of endoscopic surgical tools and small skin incisions to develop a minimally invasive approach for TAA replacement. The following procedures were used: endoscopic exposure and closure of the lower intercostal arteries; small posterolateral thoracotomy and left retroperitoneal incisions to expose the anastomotic regions of the aorta; partial anticoagulation; passive bypass and sequential aortic clamping; tunnelling of the graft through the native aortic lumen (endoaneurysmorrhaphy) and open performance of vascular anastomosis...

Endovascular repair has revolutionised the emergency treatment of thoracic aortic disease. We report our 10 year experience using this treatment in emergency cases. A prospectively maintained vascular database was analysed. Patients' medical records and CT images stored on the hospital PACS system were also reviewed. Statistical analysis was done using IBM SPSS V21. There were a total of 59 thoracic aortic stenting procedures of which 33 (60% males with a mean age of 58 yrs) were performed for emergency thoracic pathologies: traumatic transection (n = 10), ruptured aneurysm (n = 6), non-traumatic dissection (n = 8) and penetrating aortic ulcer (n = 9)...

Left subclavian artery (LSA) revascularization is recommended during elective thoracic endovascular aortic aneurysm repair (TEVAR) when coverage is required for adequate proximal seal. Reported method for LSA revascularization includes open bypass, covered stent placement using chimney technique, and in situ laser fenestration. We reported a novel technique using percutaneous Outback reentry device for LSA revascularization in a 68-year-old male patient who underwent TEVAR for a 9-cm thoracic aortic aneurysm...

BACKGROUND: The use of antiangiogenic therapy in non-small cell lung cancer (NSCLC) requires thorough evaluation of patient characteristics in order to avoid potential safety issues, particularly pulmonary haemorrhage (PH). The aim of this consensus by a panel of experts was to identify important criteria for the selection of patients with NSCLC who would benefit from antiangiogenic therapy. METHODS: Radiologists and oncologists were selected for the expert panel...

OBJECTIVES: Reference values of aortic deformation during the cardiac cycle can be valuable for the pre-operative planning of thoracic endovascular aortic repair (TEVAR) and for facilitating computational fluid dynamics. This study aimed to quantify normal aortic extensibility (longitudinal extension) and distensibility (radial expansion), as well as pulsatile strain, in a group of 10 (>60 years) individuals with abdominal or thoracic aortic aneurysms. METHODS: ECG gated CT images of the thoracic aorta were reconstructed into virtual 3D models of aortic geometry...

Aneurysmal bone cyst is a rare benign cystic bone lesion with an incidence of only 0.14 per 100,000 individuals and most commonly affects the metaphyses of long bones, spine, and pelvis. We present a very rare case of a 17-year-old boy with a rapidly expanding aneurysmal bone cyst arising from the first rib, resulting in neurogenic thoracic outlet syndrome secondary to its compression of the brachial plexus. The patient's symptoms resolved after en bloc resection. To our knowledge there have been no other reports in the literature of thoracic outlet syndrome due to aneurysmal bone cyst arising from the first rib...

Frozen elephant trunk (FET) technique combines open surgery and endovascular repair for extensive thoracic aortic aneurysms. When a FET is inserted into the descending thoracic aorta, it is difficult to confirm its proper positioning. Here we report a radiopaque ruler-guided FET technique. On the basis of preoperative computed tomography, we create a roadmap which shows the relationship between the descending thoracic aorta and vertebrae. During surgery, a radiopaque ruler placed beneath the patient's back provides the accurate target position under fluoroscopy...

A 74-year-old man with multiple aortic aneurysms and shaggy aorta was simultaneously treated by conventional open repair for an abdominal aortic aneurysm and endoluminal stent grafting for a thoracic aortic aneurysm. We performed intermittent clamping of the visceral and carotid arteries under an extracorporeal circulation circuit without a blood flow pump, which lead to the avoidance of embolization in spite of the disadvantage of endoluminal stent grafting for atheromatous aorta.
