Aneurysms are local dilations of an artery that predispose the vessel to sudden rupture. They are often asymptomatic and undiagnosed, resulting in a high mortality rate. The predisposition to develop thoracic aortic aneurysms is often genetically inherited and associated with syndromes affecting connective tissue homeostasis. This review discusses how elucidation of the genetic causes of syndromic forms of thoracic aortic aneurysm has helped identify pathways that contribute to disease progression, including those activated by TGF-β, angiotensin II and Notch ligands...

Hitoshi Matsuda
Hospital mortality after the replacement of chronic type B aortic dissection is around 8-10% and adverse outcomes include paraplegia and stroke. However, the level of evidence for indication of thoracic endovascular aortic repair (TEVAR) for type B chronic aortic dissection is Class IIa. Results of the INSTEAD-XL trial have verified that preemptive TEVAR for uncomplicated type B aortic dissection improves prognosis. The indication for this procedure is reportedly a maximum aortic diameter >40 mm during the acute phase and a patent primary entry site in the thoracic aorta, while the optimal timing for TEVAR would be the subacute phase, from 2 weeks to 3-6 months after onset...

Cheng Xue, Chen-Chen Zhou, Ming Wu, Chang-Lin Mei
BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic hereditary kidney disease characterized by progressive enlargement of renal cysts. The incidence is 1-2‰ worldwide. Mutations in two genes (PKD1 and PKD2) cause ADPKD. Currently, there is no pharmaceutical treatment available for ADPKD patients in China. Summary: This review focused on advances in clinical manifestation, gene diagnosis, risk factors, and management of ADPKD in China. There is an age-dependent increase in total kidney volume (TKV) and decrease in renal function in Chinese ADPKD patients...

BACKGROUND: We report a case of steroid-resistant Tolosa-Hunt syndrome (THS) with recurrent bilateral painful ophthalmoplegia, accompanied with sphenoid sinusitis, pituitary abscess, and an aneurysm arising from the cavernous portion of the internal carotid artery. CASE DESCRIPTION: A 53-year-old woman suffered severe left painful ophthalmoplegia. A magnetic resonance image (MRI) revealed thickness of the left cavernous sinus (CS). Steroid was administrated under the diagnosis of THS, and the symptom transiently diminished...

INTRODUCTION: Single stent deployment leads to a change in vascular geometry in wide necked bifurcation aneurysms. In some complex cases, the use of the single stent technique might not be sufficient or may not be feasible. The kissing-Y stenting technique appears to be an alternative endovascular treatment option. The aim of this study was to evaluate the effects of the kissing-Y stenting technique on vascular angular remodeling. METHODS: 21 patients with wide necked intracranial bifurcation aneurysms at different sites (10 anterior communicating artery, 6 middle cerebral artery, 3 basilar artery, 1 vertebral artery/posterior inferior cerebellar artery, 1 internal carotid artery/posterior communicating artery) were treated with 44 closed cell stents (follow-up 2012-2016) using the kissing-Y stenting technique...

OBJECTIVE: To evaluate the impact of preoperative pulmonary function on outcomes after open repair of descending thoracic (DTA) and thoracoabdominal aortic (TAAA) aneurysms. METHODS: The outcomes of patients undergoing open repair of DTA or TAAA were analyzed in relation to the results of preoperative pulmonary function tests. Receiver operating characteristic was adopted to assess the effect of forced expiratory volume in one second (FEV1) on the incidence of mortality...

A 45-year-old man with severe left flank pain was brought by ambulance to our hospital early in the morning. On arrival, his circulation dynamics were stable. His urinalysis results were normal, and ultrasonography showed no hydronephrosis. Abdominal dynamic computed tomography (CT) showed a huge retroperitoneal hematoma suspected of hemorrhage from a left adrenal artery aneurysm. After 3 hours of absolute bed rest, the patient experienced episodes of anemia, decreased blood pressure and increased pulse. Recheck of CT showed bleeding into the peritoneal cavity...

BACKGROUND: Jaw pseudocysts are benign osseous lesions of unclear etiology. Among these, the simple bone cyst (SBC) and aneurysmal bone cyst (ABC) are intriguing bone pathologies still rarely studied together. This retrospective study aimed to present the long-term case series of patients with jaw pseudocysts focusing on the clinical, radiographic, and transoperative aspects. MATERIAL AND METHODS: A retrospective case series of patients with SBC and ABC was performed...

A patient with an aortobronchial fistula secondary to a thoracic endovascular aortic repair was successfully treated with a re-thoracic endovascular aortic repair with debranching technique. Five months postoperatively, the aneurysm had shrunk; however, computed tomography revealed air in the thrombo-excluded aortic aneurysmal sac without signs of infection. Because of worsening air finding at the eighth month, we performed a resection of the residual fistula and wrapped the stent graft in a pedicled muscle flap...

Matrix metalloproteinase (MMP)-12 plays a key role in the development of aneurysm. Like other members of MMP family, MMP-12 is produced as a proenzyme, mainly by macrophages, and undergoes proteolytic activation to generate an active form. Accordingly, molecular imaging of the MMP-12 active form can inform of the pathogenic process in aneurysm. Here, we developed a novel family of fluorescent probes based on a selective MMP-12 inhibitor, RXP470.1 to target the active form of MMP-12. These probes were stable in complex media and retained the high affinity and selectivity of RXP470...

OBJECTIVE: The decision whether or not to proceed with surgical intervention of a patient with a ruptured abdominal aortic aneurysm (rAAA) is very difficult in daily practice. The primary objective of the present study was to develop and to externally validate a new prediction model: the Dutch Aneurysm Score (DAS). METHODS: With a prospective cohort of 10 hospitals (n = 508) the DAS was developed using a multivariate logistic regression model. Two retrospective cohorts with rAAA patients from two hospitals (n = 373) were used for external validation...

BACKGROUND: Open repair of thoracoabdominal and descending thoracic aneurysm (TAA) carries significant operative morbidity and mortality. Despite evolving operative techniques patient-level risk factors affecting mortality after open TAA repair, including patient functional status, remain to be fully understood. MATERIALS AND METHODS: We identified all open TAA repair cases in the National Surgical Quality Improvement Program database between 2005 and 2013. Multivariable logistic regression was used to evaluate the effect of patients' age, gender, race, body mass index (BMI), comorbid conditions, functional status, ASA class, smoking, rupture, descending thoracic aneurysm versus Crawford types, dissection, and preoperative: transfusion, creatinine levels, on perioperative (30-d) mortality after open TAA repair...

BACKGROUND: In the absence of a standardized safe surgical reentry strategy for high-risk patients with large or anterior postoperative aortic false aneurysm (PAFA), we aimed to describe an effective and safe approach for such patients. METHODS: We prospectively analyzed patients treated for PAFA between 2006 and 2015. According to the preoperative computed tomography scan examination, patients were divided into two groups according to the anatomy and extension of PAFA: in group A, high-risk PAFA (diameter ≥3 cm) developed in the anterior mediastinum; in group B, low-risk PAFA (diameter <3 cm) was situated posteriorly...

BACKGROUND: Peak oxygen uptake (VO2peak) established during progressive cardiopulmonary exercise testing (CPET) is the "gold-standard" for cardiorespiratory fitness. However, CPET measurements may be limited in patients with aneurysmal subarachnoid hemorrhage (a-SAH) by disease-related complaints, such as cardiovascular health-risks or anxiety. Furthermore, CPET with gas-exchange analyses require specialized knowledge and infrastructure with limited availability in most rehabilitation facilities...

BACKGROUND: Aortic disease is a lifelong, progressive illness that may require repeated intervention over time. We reviewed our 25-year experience with open redo thoracoabdominal aortic aneurysm (TAAA) and descending thoracic aortic aneurysm (DTAA) repair. Our objectives were to determine patient outcomes after redo repair of DTAA/TAAA and compare them with nonredo repair. We also attempted to identify the risk factors for poor outcome. METHODS: We reviewed all open redo TAAA and DTAA repairs between 1991 and 2014...
