Patients with deep venous thrombosis are at a short-term risk of symptomatic or even life-threatening pulmonary embolism, and a long-term risk of post-thrombotic syndrome, characterised by lower-limb pain, varicose veins, oedema, and sometimes skin ulcers. What is the best choice of initial antithrombotic therapy following deep venous thrombosis or pulmonary ...

Carotid stenosis amenable to surgical or interventional revascularization accounts for 5-12% of all new strokes. Several randomized trials have shown that carotid endarterectomy (CEA) for the treatment of symptomatic and asymptomatic carotid stenosis is superior to medical treatment. Application of a carotid artery stent (CAS) representing a good alternative for ...

Pulmonary artery dissection is a fatal complication of long-standing pulmonary hypertension, manifesting as acute, stabbing chest pain, progressive dyspnea, cardiogenic shock, or sudden death. Its incidence has been underestimated, and therapeutic options are still scarce. In patients with pulmonary hypertension, new chest pain, acute chest pain, or cardiogenic shock should ...

Obstruction and thrombosis of major systemic veins can occur due to indwelling central venous catheters. If obstruction of the innominate vein or superior vena cava occurs, lymphatic drainage can be impaired due to an increase in pressure in the thoracic duct and lymphatics. We describe a case where superior vena ...

Respiratory difficulty resulting from congenital chylothorax is usually relieved by postnatal thoracentesis, closed chest drainage, and oxygen therapy. However, early occurrence of congenital chylothorax or accumulation of a large amount of chylous fluid sometimes leads to pulmonary hypoplasia or persistent pulmonary hypertension of the newborn, which requires further customized mechanical ...
