Pulmonary hypertension (PH) is a progressive disease that is accompanied by a poor prognosis. Pulmonary vasoconstriction is facilitated through multiple pathways and results in increased pulmonary vascular pressure leading to cell proliferation, vascular remodeling, right ventricular hypertrophy/failure, and ultimately death. Until recently, just six medications were approved -all for one ...

Venous thromboembolism comprises deep-vein thrombosis, thrombus in transit, acute pulmonary embolism, and chronic thromboembolic pulmonary hypertension (CTEPH). Pulmonary thromboemboli commonly resolve, with restoration of normal pulmonary hemodynamics. When they fail to resorb, permanent occlusion of the deep veins and/or CTEPH are the consequences. Apart from endogenous fibrinolysis, venous thrombi resolve ...

The pathobiology of pulmonary arterial hypertension (PAH) is complex and multifactorial. None of the current therapies has been shown to be universally effective or able to reverse advanced pulmonary vascular disease, characterized by plexiform vascular lesions, or to prevent right ventricular failure in advanced PAH. It is thus unlikely that ...

Hematopoiesis and vascular homeostasis are closely linked to each other via subsets of circulating bone marrow-derived cells with potent activity to repair endothelial injury and promote angiogenesis. As a consequence, abnormalities in hematopoiesis will eventually affect vascular health. Pulmonary arterial hypertension (PAH) is a vascular disease characterized by severe remodeling ...

Percutaneous coronary intervention is the most prevalent method for coronary artery revascularization. Initial interventions using balloon angioplasty had limited efficacy because coronary dissections, arterial recoil, and neointimal formation led to high rates of abrupt vessel closure and clinical restenosis. With the introduction of coronary stents, vascular dissections were stabilized and ...

The safety of anesthesia has improved greatly in the past three decades. Standard perioperative monitoring, including pulse oximetry, has practically eliminated unrecognized arterial hypoxia as a cause for perioperative injury. However, most anesthesia-related cardiac arrests in children are now cardiovascular in origin, and standard monitoring is unable to detect many ...

The "accordion effect" is a mechanical remodeling of the arterial wall produced by endoluminal introduction of stiff guidewires, leading to vessel wall shortening and development of multiple eccentric constrictions. This phenomenon is unresponsive to vasodilators and may lead to unnecessary stenting of the pseudo-lesions. It must be suspected with the ...

Stent graft placement for ureteroarterial fistula is the preferred treatment. However, some pitfalls may occur during the procedure. Chronic inflammation process will induce longer adhesion area between artery and ureter, which results in unusual fistula site and rigid iliac arteries. This further leads to difficulty in advancing the endograft delivery ...

Evidence from observational studies suggests that mild-to-moderate consumption of red wine is associated with reduced cardiovascular morbidity and mortality. Various individual chemical components of red wine also show salutary effects on vascular homeostasis, that is, enhanced endothelial function and arterial distensibility, both in vitro and in animal studies. However, testing ...

Endobronchial tumours requiring sleeve resection have been usually considered a contraindication for video-assisted thoracoscopic surgery (VATS). However, with new technical advances and the experience gained in VATS, sleeve lobectomy has been performed by thoracoscopy in experienced VATS centres. Right-sided sleeve anastomoses are easier to perform by VATS than left-sided ones ...

The peroneal artery is an important outflow vessel for lower limb revascularization and limb salvage. This vessel is commonly reached using a medial, posterior, or lateral approach with resection of the fibula. We present a technique of lateral approach to the peroneal artery without fibular resection.

Life-threatening hemorrhage rarely occurs from the portal vein following blunt hepatic trauma. Traditionally, severe portal bleeding in this setting has been controlled by surgical techniques such as packing, ligation, and venorrhaphy. The presence of portal hypertension could potentially increase the amount of hemorrhage in the setting of blunt portal vein ...

Lenticulostriate artery aneurysms are rare, can be difficult to diagnoze, and when they rupture they are often associated with deep intraparenchymal hemorrhages. In particular, fusiform, dissecting aneurysms of a distal lenticulostriate artery are extremely rare. Typically, they are usually associated with underlying systemic conditions such as systemic lupus erythematosus, moyamoya ...

Over the past 20 years, great progress has been made in the treatment of pulmonary arterial hypertension (PAH). Available therapies target one of three principal pathways: the endothelin (ET), nitric oxide (NO) or the prostacyclin (PGI2) pathway. Evidence shows that current drugs, used either as monotherapy or in different combinations, can ...
