BACKGROUND: Hypertrophic cardiomyopathy (HCM) with or without left ventricular apical aneurysm (LVA) had been studied in the past. Midventricular obstruction associated with HCM and LVA is a unique entity that has not been distinguished previously as a separate phenotypic disease in HCM patients. METHODS: A systematic review of Pubmed and Google Scholar was conducted from inception until September 2017 for all observational studies conducted on HCM with midventricular obstruction and LVA...

Polyarteritis nodosa is a chronic systemic vasculitis, characterized by the autoimmune, necrotising lesion of the walls of the small- and medium-bore visceral and peripheral arteries, resulting in vessel aneurysms and the secondary degeneration of organs and systems. All types of vessels (arteries, veins, capillaries) can be affected or, alternatively, the process can be limited predominantly to the vessels of one system, the clinical symptoms depending on the bore and location of the affected vessels. Varying degrees of the lesion, varying combinations and sequencing, the compensation abilities of the vessel disorders can blur the clinical picture, even though early pathomorphological changes are quite pronounced...

Chimney-and-periscope technique for thoraco-abdominal aneurysm repair is a valuable treatment option in selected patients. Acute renal artery occlusion is a serious complication after this technique. We report a case of acute right renal artery occlusion, consequent to a previous chimney-and-periscope technique that was treated urgently by mechanical aspiration thrombectomy.

Chronic aortic dissecting aneurysms (TAAD) presenting after acute Stanford Type A or B dissection includes both arch and/or thoracoabdominal aortic aneurysms (TAAA). Approximately 60% of patients who survive surgical treatment of acute Type A aortic dissections will require another aortic procedure. Similarly, more than 70% of patients with chronic Type B aortic dissections will experience false lumen dilation at 5-year follow-up, often requiring intervention. Open or hybrid aortic repairs of complex TAAD involving the arch and the TAAA are very demanding procedures for both patients and clinicians...

PURPOSE: To investigate the initial proximal position and seal of the Nellix EndoVascular Aneurysm Sealing (EVAS) system in the aortic neck using a novel methodology. METHODS: Forty-six consecutive patients who underwent elective EVAS for an abdominal aortic aneurysm were retrospectively selected and dichotomized into an early (n = 23) and a late (n = 23) group. The aortic neck morphology and aortic neck surface (ANS) were determined on preoperative computed tomography (CT) scans; the endograft position and nonapposition surface (NAS) were determined on the 1-month CT scans...

BACKGROUND: Circulatory collapse is a leading cause of mortality among traumatic major exsanguination and in ruptured aortic aneurysm patients. Approximately 40% of patients die before hemorrhage control is achieved. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an adjunct designed to sustain the circulation until definitive surgical or endovascular repair. A systematic review was conducted for the current clinical use of REBOA in patients with hemodynamic instability and to discuss its potential role in improving prehospital and in-hospital outcome...

OBJECTIVE: Proximal neck dilation is a serious long-term complication directly causing the failure of endovascular aneurysm repair (EVAR) and open surgical repair (OSR) of abdominal aortic aneurysms. However, the implantation of a fenestrated device presents the opportunity for proximal extension of the aortic reconstruction into a healthy segment while maintaining patency of the visceral vessels. The objective of this investigation was to report perioperative and follow-up outcomes using the Zenith Fenestrated (ZFEN; Cook Medical, Bloomington, Ind) aortic stent system in salvaging previous aortic repairs undergoing type IA endoleak or aneurysmal degeneration of the proximal neck...

OBJECTIVE: Thoracic endovascular aortic repair (TEVAR) is the standard treatment of blunt thoracic aortic injury (BTAI). The concept of seal was derived from the treatment of aneurysms and has been adopted for BTAI. Given the location of injury in BTAI, left subclavian artery (LSA) coverage is sometimes necessary. In these often healthier aortas, a shorter proximal landing zone may be acceptable and beneficial in avoiding some complications. Current practice patterns vary, and long-term effects of LSA coverage remain unknown...

Background and purpose Current large-bore catheters can be easily and safely placed in the intracranial vessels for the stabilization of microcatheters in several neurointervention scenarios. We considered that a novel 3.4 French catheter (TACTICS, Technorat Corporation, Aichi, Japan) might be useful for intermediate/distal access in a triaxial system. Here, we present our initial experience using the TACTICS catheter for treatment of intracranial aneurysms. Materials and methods A total of 35 endovascular coils were placed to embolize unruptured intracranial aneurysms of the anterior circulation using the TACTICS catheter between December 2016 and November 2017...

Endovascular treatment of intracranial aneurysms using flow-diverting devices has revolutionized the treatment of large and complex lesions due to its minimally invasive nature and potential clinical outcomes. However, incomplete or delayed occlusion and persistent intracranial aneurysm growth are still an issue for up to one-third of the patients. We evaluated two patients with intracranial aneurysm located at the internal carotid artery who were treated with flow-diverting devices and had opposite outcomes...

BACKGROUND: Guidelines for aneurysm subarachnoid hemorrhage (aSAH) management recommend treatment with nimodipine to all patients to reduce delayed cerebral ischemia (DCI) and poor clinical outcome. However, it did not give the most beneficial time to start therapy and route of administration. OBJECTIVES: To compare the DCI occurrence and clinical outcome among aSAH patients who received nimodipine treatment at different times. METHODS: A retrospective cohort study was conducted by collecting data from medical chart reviews between August 30, 2010, and October 31, 2015, at Prasart Neurological Institute, Thailand...

Background: There is a potential for direct model manufacturing of abdominal aortic aneurysm (AAA) using 3D printing technique for generating flexible semi-transparent prototypes. A patient-specific AAA model was manufactured using fused deposition modelling (FDM) 3D printing technology. A flexible, semi-transparent thermoplastic polyurethane (TPU), called Cheetah Water (produced by Ninjatek, USA), was used as the flexible, transparent material for model manufacture with a hydrophilic support structure 3D printed with polyvinyl alcohol (PVA)...

We present here a case of successful staged treatment of a patient with para-aortic abscess that arose 5 years after thoracic endovascular aortic repair because of thoracic aortic aneurysm. After stabilization of the patient's condition by intensive antibiotic therapy we performed left-subclavian extra-thoracic debranching as the first stage of the surgical treatment. In 2 weeks via median sternotomy and on-pump we removed the infected endograft and performed extraanatomical ascending-to-descending aortic bypass with good postoperative result...

BACKGROUND: In patients undergoing open surgery for a ruptured abdominal aortic aneurysm (rAAA), survivors demonstrate a high platelet count, and proactive administration of platelets (and fresh frozen plasma) appears to influence mortality. OBJECTIVES: This trial investigated the effect of platelets administered before transport to surgery. METHODS: In a prospective study design, patients were randomised to receive platelets (intervention; n = 61) or no platelets (control; n = 61) before transport to vascular surgery from 11 local hospitals...

Endovascular approach represents today the first option in treatment of ruptured and unruptured cerebral aneurysms. Nevertheless, wide-neck bifurcation aneurysms still represent a technical challenge for endovascular treatment due to the need to protect vessels arising next to the aneurysmal neck. A variety of devices have been implemented to ensure adequate assistance for coiling of these lesions. Among these devices, the new pCONus 2 represents an evolution of the well-known pCONus; compared to the previous one in fact, it allows a degree of articulation and flexibility between the shaft and the distal part (crown), making it more suitable for treatment of aneurysms presenting an angle between the longitudinal axis of the dome and parent vessel...
