Chest radiography indicated a well-defined rounded mass at the left lung hilum in a 77-year-old former smoker. Chest computed tomography revealed a longitudinal saccular enlargement of the left pulmonary artery with surrounding soft tissue opacity. Resection of the left lower lobe with segment 1 + 2c was carried out to completely remove the dilated pulmonary artery. The resected specimen revealed obvious dilatation of the interlobar pulmonary artery and its branches. A small yellowish well-demarcated myxoid tumor was contained in this lesion, which was diagnosed as a primary pulmonary artery intramural leiomyosarcoma...

Percutaneous endovascular techniques are used increasingly in the vascular armamentarium. Commonly performed as day case procedures under local anaesthetic, they are suited to the highly co-morbid vascular patient population. Furthermore, technological advances have resulted in ever improving outcomes for aneurysmal and occlusive disease. Endovascular procedures such as endovascular aneurysm repair or iliac artery stenting are traditionally associated with reduced infectious complications compared to equivalent open techniques...

BACKGROUND: Intra-neural arachnoid cyst is an extremely rare etiology of isolated cranial nerve palsy. Although seldom encountered in clinical practice, this pathology is amenable to surgical intervention. Correct identification and treatment of the cyst are required to prevent permanent nerve damage and potentially reverse the deficits. We describe a rare case of isolated third nerve palsy caused by an intra-neural arachnoid cyst. CASE DESCRIPTION: A 49 year old female with recent history of headaches presented with acute onset of painless left-sided 3rd nerve palsy...

BACKROUND: Aneurysms of the distal anterior cerebral artery (DACA) are rare, representing between 1% and 9% of all intracranial aneurysms. The best treatment strategy for these aneurysms continue to be debated. OBJECTIVE: We conducted a systematic review of the literature to evaluate the safety and efficacy of treatment strategies of DACA-aneurysms. METHODS: A systematic search of Medline, EMBASE, Scopus and Web of Science was done for studies published from 01/2000 to 08/2015...

BACKGROUND: The goal of the treatment of direct carotid cavernous fistula (CCF) is to occlude the arteriovenous shunt and to preserve the patency of the concerned internal carotid artery (ICA). However, for the ipsilateral post-traumatic fragile cerebrum, coil embolization plus parent artery occlusion for the high flow direct CCF would be better for the prevention of hyper-perfusion syndrome and the intracranial hemorrhage. We experienced such a case and managed it successfully. CASE DESCRIPTION: A 6-year-old boy was suffered from severe head trauma caused by being hit by a car...

OBJECTIVE: Few data are available regarding the surgical strategies for an anomalous origin of the left coronary artery (LCA) from the right pulmonary artery (RPA) with an intramural aortic course. We reviewed our experience in a case series of 10 children. METHODS: From 2007 to 2014, 10 patients (7 boys and 3 girls, aged 3 months to 11 years, median 21 months) underwent surgical repair. Before the operation, echocardiography showed the mean left ventricular ejection fraction 45% ± 10% and mean fractional shortening fraction 21% ± 7%...

OBJECTIVE: Membrane type-1 matrix metalloproteinase (MT1-MMP) is elevated during thoracic aortic aneurysm (TAA) development in mouse models, and plays an important role in the activation of matrix metalloproteinase (MMP)-2 and the release of matrix- bound transforming growth factor-β. In this study, we tested the hypothesis that MT1-MMP is subject to protein kinase C (PKC)-mediated regulation, which alters intracellular trafficking and activity with TAAs. METHODS: Levels of MMP-2, native and phosphorylated MT1-MMP, and PKC-δ were measured in aortic tissue from patients with small TAAs (<5 cm; n = 8) and large TAAs (>6...

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...

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...

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...

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...

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...
