An 81-year-old man presented with ruptured thoracic aortic aneurysm under stable condition. He had been suffering from chronic obstructive pulmonary disease, chronic renal failure and rheumatoid arthritis. We performed hybrid thoracic endovascular aortic repair via right anterior mini-thoracotomy inserting a device through a conduit on the ascending aorta. The patient was discharged without aorta-related complications.

Chronic mesenteric ischaemia (CMI) is a rare disorder caused by severe stenosis of the mesenteric arterial supply that results in post prandial pain and weight loss. Treatment options are surgical or endovascular. Surgical bypass can be performed in an antegrade fashion from the supracoeliac abdominal aorta or the distal descending thoracic aorta or in a retrograde fashion from the infra-renal aorta or the common iliac artery. However in some patients with disease of the descending thoracic aorta (DTA) or the abdominal aorta (AA) another site for the proximal anastomosis needs to be found...

We report a case of a compassionate treatment of a ruptured thoraco-abdominal aortic aneurysm in a 92-year-old patient. Patient was admitted to our emergency department for acute onset of pain irradiating to the back. Computed tomographic angiography showed the presence of a thoraco-abdominal aortic aneurysm with a contained rupture at infrarenal level. Given of the presence of a relative healthy visceral aorta, we decided to treat the patient by Ovation(®) (Endologix, Irvine, CA - USA) implantation in an off-label fashion...

Endovascular aneurysm repair (EVAR) actually represents the treatment of choice for most patients affected by aneurysm of the abdominal aorta (AAA). However, the feasibility of EVAR depends on anatomical characteristics of abdominal aorta and ilio-femoral axis. We present the case of a 82-years old man affected by severe left hydronephrosis, kidney and ureteral tumor requiring nephrectomy, that presented also a very voluminous AAA with a large diameter (96 mm), presenting also with a large proximal neck (39 mm) and with a severe angulation of the proximal neck (> 60°)...

PURPOSE: to describe the use of the combination of a conical custom-made TREO® (TREO CM) stent-graft in the treatment of a saccular abdominal aortic endograft (AAA) with long but tight and calcified distal neck. TECHNIQUE: A 65-year female patient was treated for a saccular 5.2 cm AAA with a 3cm-long but calcified and tight (16mm) distal neck, precluding the safe use of a bifurcated endograft. Since the patient refused an open surgery, a conical TREO CM endograft was manufactured with 20% proximal oversizing, whereas the 3cm caudal sealing segment demonstrated a conical configuration comprised of a 2cm and 1cm nitinol-supported zones of 20% and 10% oversizing, respectively, in order to avoid excessive strain and incomplete expand at the most distal calcified area, leading ultimately to an insidious infolding and consequent type Ib endoleak...

Infectious aortitis (IA) is a rare but life-threatening condition, and most commonly affects the abdominal aorta or thoracic aorta. Various microorganisms have been associated with infectious thoracic aortitis, most commonly Staphylococcus, Enterococcus, Streptococcus, and Salmonella species. Campylobacter fetus (C. fetus) has been seen as a cause of infective aortitis only in a few case reports. We report a rare case of infective aortitis of the abdominal aorta caused due to C. fetus bacteremia. While C. fetus infections usually occur in patients with immunosuppression, such as malignancy, or those with diabetes mellitus, but our patient was not immunocompromised...

We herein report an unusual case of an infected descending aortic pseudoaneurysm with luminal pathognomonic oscillating vegetation with serological findings and clinical features mimicking anti-proteinase 3-antineutrophil cytoplasmic antibody-associated vasculitis. The positive blood cultures and imaging findings, including a pseudoaneurysm and vegetations in the aorta, suggested the presence of an infected aortic aneurysm. The patient was successfully treated with antibiotics and endovascular aortic repair...

Soft biological tissues such as aortic walls can be viewed as fibrous composites assembled by a ground matrix and embedded families of collagen fibres. Changes in the structural components of aortic walls such as the ground matrix and the embedded families of collagen fibres have been shown to play a significant role in the pathogenesis of aortic degeneration. Hence, there is a need to develop a deeper understanding of the microstructure and the related mechanics of aortic walls. In this study, tissue samples from 17 human abdominal aortas (AA) and from 11 abdominal aortic aneurysms (AAA) are systematically analysed and compared with respect to their structural and mechanical differences...

Endovascular repair of dissecting thoracoabdominal aneurysms (TAAA) is challenging and often requires multiple procedures. A 61-year-old man with a dissecting type-II TAAA treated first by placement of a thoracic endograft, and subsequently implantation of a fenestrated endograft. Six months postoperatively, a 10mm increase of the aorta was observed. A re-entry tear in left external iliac artery(EIA) was perfusing the false lumen in a retrograde fashion connecting with the endoleak caused by the inferior mesenteric artery and lumbar arteries...

OBJECTIVE: Alloplastic aortic graft infection is a devastating complication following aortic surgery. It is associated with excessively high mortality and morbidity caused by anastomotic rupture or septicemia. Many authors consider in situ replacement after complete surgical graft removal as the method of choice. However, there is an ongoing debate about the most suitable material for reconstruction. We present our first experiences with replacing the descending and infra-renal aorta using custom-made bovine pericardium grafts...

Direct numerical simulations were performed on four patient-specific abdominal aortic aneurysm (AAA) geometries and the resulting pulsatile blood flow dynamics were compared to aneurysm shape and correlated with intraluminal thrombus (ILT) deposition. For three of the cases, turbulent vortex structures impinged/sheared along the anterior wall and along the posterior wall a zone of recirculating blood formed. Within the impingement region the AAA wall was devoid of ILT and remote to this region there was an accumulation of ILT...

Takayasu arteritis (TA) is the third most common childhood vasculitis and its clinical manifestations depend on the arteries involved. We report a case of a 9-year-old boy with multiple aneurysms in carotid and iliac arteries, subclavian and coronary arteries, and abdominal aorta. At the age of 7 years, he presented with recurrent fever and hepatosplenomegaly. An angio-computed tomography scan showed aneurysms in the left subclavian artery, abdominal aorta, and both proximal iliac arteries. He was diagnosed with TA and was treated with corticosteroids, aspirin, and enalapril...

Marfan syndrome (MFS) is a heritable connective tissue disorder caused by mutations in FBN1, which encodes the extracellular matrix protein fibrillin-1. To investigate the pathogenesis of aortic aneurysms in MFS, we generated a vascular model derived from human induced pluripotent stem cells (MFS-hiPSCs). Our MFS-hiPSC-derived smooth muscle cells (SMCs) recapitulated the pathology seen in Marfan aortas, including defects in fibrillin-1 accumulation, extracellular matrix degradation, transforming growth factor-β (TGF-β) signaling, contraction and apoptosis; abnormalities were corrected by CRISPR-based editing of the FBN1 mutation...

Abdominal aortic aneurysms (AAA) represent permanent, localized dilations of the abdominal aorta that can be life-threatening if progressing to rupture. Evaluation of risk of rupture depends on understanding the mechanical behavior of patient AAA walls. In this project, a series of patient AAA wall tissue samples have been evaluated through a combined anamnestic, mechanical and histopathologic approach. Mechanical properties of the samples have been characterized using a novel, strain-controlled, planar biaxial testing protocol emulating the in vivo deformation of the aorta...

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment option for thoracic aorta aneurysms (TAA). Endovascular access is a challenge. We present a novel TEVAR technique in a patient with single kidney and a 6.4 cm TAA. Attempting to place a sheath through iliac arteries was unsuccessful. The decision to proceed to hybrid TEVAR was made. The protection of the solitary kidney was achieved through axillo-femoral bypass, followed by an end-to-side anastomosis between the aorta and a bifurcated graft...

PURPOSE: To report a hybrid technique for the treatment of a suprarenal aortic aneurysm (SAA) in a patient with iliac occlusive disease. Initially an infrarenal aorto-bifemoral surgical graft was implanted, followed by deployment of a fenestrated bifurcated stent-graft at the suprarenal part of the aorta. CASE REPORT: A 69-year old man presented with a 51-mm saccular SAA and iliac occlusive disease with intermittent claudication. Both common iliac arteries had been previously treated with kissing stents...

PURPOSE: To present our early experience and highlight the technical difficulties associated with the use of fenestrated and branched stent-grafts to treat patients with juxta-, para-renal abdominal aortic aneurysms (AAA) and thoracoabdominal aortic aneurysms (TAAA). METHODS: A prospectively held database maintained at our department, was queried for patients who have undergone branched and fenestrated stent-grafting for AAA or TAAA treatment. Indication for repair, co-morbidity precluding open repair, technical challenges associated with the repair, as well as operative mortality, morbidity and re-intervention rate were evaluated...

PURPOSE: Feasibility and early satisfactory results of physician-modified endografts have been reported. Most reports described the use of Cook Dacron aortic endografts (Cook Medical Inc, Bloomingtion, Ind). However, in some specific anatomic features (short aortic lenght, narrow aorta), use of this device may not appropriate. CASE REPORT: We here report a case of juxtarenal aortic aneuvrysm proximal to a former aortobifemoral graft in a high surgical risk patient...

OBJECTIVE: To describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. METHODS: In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement...

OBJECTIVE/BACKGROUND: Abdominal aortic aneurysm (AAA) is characterised by the infiltration of smooth muscle cell (SMC) apoptosis, inflammatory cells, neovascularisation, and degradation of the extracellular matrix. Previous work has shown that endoplasmic reticulum (ER) stress and SMC apoptosis were increased both in a mouse model and human thoracic aortic aneurysm. However, whether the ER stress is activated in AAA formation and whether suppressing ER stress attenuates AAA is unknown...
