The purpose of this report is to describe a minimally invasive alternative endovascular technique for the treatment of chronically occluded stents when it is not possible to cross them endoluminally. A 71-years-old patient with recurrent severe lower limb claudication due to occlusion of a stent placed in the common iliac artery 5 years earlier underwent subintimal recanalization of the stented segment and re-stenting after failed intraluminal approach. The postoperative CT scan showed that the re-stented segment was patent with a flattening of the previous stent...

INTRODUCTION: Endoleaks are a well-known complication after endovascular aortic repair. Type I endoleak-like phenomenon (also defined as a proximal pseudoaneurysm) post-open abdominal aortic aneurysm (AAA) repair is described as an anastomotic leak causing recurrent pressurization of the original aneurysm sac. It is rare but may result in aneurysmal sac rupture into the peritoneal cavity. REPORT: A 78-year-old man presented with a progressively enlarged aneurysmal sac due to proximal anastomotic degeneration of the proximal suture line associated with an outflow through a patent large lumbar vessel following a previous emergency open AAA repair...

We present a 63-year-old male patient who presented with vague abdominal pain after an endoluminal thoracoabdominal aneurysm repair. He was found to have an infected endograft and an associated type IIIb endoleak. We believe that the infection contributed to the fabric degradation along the endograft and resulted in an expanding endoleak. Graft explantation was not performed because of the patient's multiple comorbidities, and the endoleak was treated with an additional stent graft and suppressive antibiotics...

Aneurysm formation and recurrent coarctation are common complications of coarctation repair, and various types of treatment have been described. Native aortic coarctation during adult life is rarer and can be responsible for severe complications. We report an original case of thoracic aortic aneurysm associated with native coarctation successfully treated by a hybrid approach, comprising retrograde implantation of a thoracic stent graft and carotid-axillary bypass graft. A large intercostal collateral was embolized with coils...

BACKGROUND: Flow diverters offer a promising treatment for cerebral aneurysms. However, they have associated thromboembolic risks, mandating chronic dual antiplatelet therapy (DAPT). Shield Technology is a phosphorylcholine surface modification of the Pipeline Embolization Device (PED) flow diverter, which has shown significant reductions in material thrombogenicity in vitro. OBJECTIVE: To compare the thrombogenicity of PED, PED with Shield Technology (PED+Shield), and the Flow-Redirection Endoluminal Device (FRED)-with and without single antiplatelet therapy and DAPT-under physiological flow...

Carotid artery dissection is a common cause of juvenile stroke. Endovascular treatment of acute stroke due to carotid dissection can be challenging, and endoluminal crossing of the dissection is sometimes impossible. We describe a case of intentional subintimal recanalisation of a cervical carotid dissection followed by intracranial thrombectomy and stenting. We report the case of a young woman with severe acute ischaemic stroke due to carotid artery dissection and intracranial embolism. After failure of endoluminal crossing of the dissected segment, intentional subintimal crossing with re-entry distally to the dissection was achieved and a stent was deployed...

The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years...

The prevalence of subjects with colorectal cancer is expected to grow in the next future decades and surgery represents the most successful treatment modality for these patients. Anyway, currently elderly subjects undergo less elective surgical procedures than younger patients mainly due to the high rates of postoperative morbidity and mortality. Some authors suggest extensive surgery, including multistage procedures, as carried out in younger patients while others promote less aggressive surgery. In older patients, laparoscopic-assisted colectomy showed a number of advantages compared to conventional open surgery that include lower stress, higher rate of independency after surgery, quicker return to prior activities and a decrease in costs...

Intravascular ultrasound (IVUS) can provide valuable information regarding endoluminal morphology. We present the first description of IVUS-guided intracranial and extracranial carotid artery stent placement for arterial dissection. A 41-year-old female with a sudden-onset headache and blurred vision underwent a computed tomography (CT) angiogram imaging that revealed bilateral carotid artery dissections (BCAD) and a left vertebral artery dissection (VAD). Endovascular treatment (EVT) of a long segment right carotid artery dissection (CAD) was performed employing two Carotid WALLSTENT™ Monorails™ (8 x 36 mm, 10 x 31 mm) (Boston Scientific, Marlborough, MA)...

Full-thickness gastrointestinal defects such as perforation, anastomotic leak, and fistula are severe conditions caused by various types of pathologies. They are more likely to require intensive care and a long hospital stay and have high rates of morbidity and mortality. After intentional full-thickness opening of hollow organs for natural orifice transluminal endoscopic surgery, safe and secure closure is urgently required. The currently available advanced endoscopic closing techniques have a major role in the treatment of full-thickness gastrointestinal defects...

INTRODUCTION: Cavernous carotid aneurysms can cause significant symptomatology through mass effect and may rupture, resulting in carotid-cavernous fistula or epistaxis. Traditional treatment options included endovascular or surgical parent vessel occlusion, or embolization; in the last decade, the development of flow-diverting stents has changed the management paradigm for these lesions. AREAS COVERED: In this review, we summarize the natural history, clinical presentation, and evolution of treatment options for cavernous carotid aneurysms and discuss developments likely to influence treatment strategies in the future...

BACKGROUND: Neoplastic involvement of the mediastinum can contribute to both airway and esophageal pathology. That can manifest as combined esophageal and airway stenosis, or tracheobronchoesophageal fistula. Conventional palliative treatment of these problems consists of endoluminal stent insertion. The double stenting approach consists of insertion of a tracheobronchial and an esophageal stent in parallel and allows concomitant symptomatic relief of both the airway and esophageal pathology...
