Postpneumonectomy syndrome is a recognized complication following pneumonectomy, resulting from mediastinal displacement into the vacated pleural space. Mediastinal displacement causes bronchial compression and dyspnea. This report describes a 47-year-old woman who presented with shortness of breath 6 months after a left pneumonectomy. She was initially hypoxic and was found to ...

Balloon atrial septostomy is a common palliative procedure in D-transposition of great arteries. It is technically easy before 2-3 weeks of age when the septum primum is thin. Femoral vein or umbilical vein, when available, is the common access used for this procedure. In situations when these accesses are not ...

Central vein catheterization is a common procedure for monitoring the central venous pressure, securing vascular access, administrating vasoactive drugs and removing air embolisms. However, many complications can occur, such as vessel injury, pneumothorax, hydrothorax, nerve injury, arrhythmia and infection at the insertion site. We encountered an unusual complication of a ...

OBJECTIVES: Prior research has demonstrated that rigid cervical collars cause an increase in intracranial pressure (ICP). The mechanism for this effect is unclear and one proposed mechanism involves obstruction of venous outflow in the neck. Ultrasound (US) allows assessment of internal jugular vein dimensions and may yield information regarding the ...

We report the case of a 40-year-old man with a recurrent popliteal vein aneurysm diagnosed 2 years after initial lateral aneurysmectomy. Definitive management consisted of popliteal vein aneurysm resection and reconstruction with an interposition spiral vein graft. Our case suggests that aneurysm vein resection and interposition vein graft should be ...

Leaf venation in many C(4) species is characterized by high vein density, essential in facilitating rapid intercellular diffusion of C(4) photosynthetic metabolites between different tissues (mesophyll, bundle sheath). Greater vein density has been hypothesized to be an early step in C(4) photosynthesis evolution. Development of C(4) vein patterning is thought ...

Veins have historically been discussed in qualitative, relative terms: "more compliant" than arteries, subject to "lower pressures". The structural and compositional differences between arteries and veins are directly related to the different functions of these vessels. Veins are often used as grafts to reroute flow from atherosclerotic arteries, and venous ...

Although the incidence of causing an atrioesophageal fistula during pulmonary vein isolation is very low, this type of injury results in a very high mortality rate. To prevent this complication, keeping a safe distance from the esophagus to the ablation lesion is a simple but safe method. We report a ...

Chronic jugular vein or central venous cannulation is routinely performed in human and animal patients for access to blood circulation. In mature swine, chronic catheter placement techniques have typically involved venous isolation via extensive cut-down, blunt dissection and manipulation of ventral neck tissues prior to catheter placement. More recently, guide-wire-assisted ...

PURPOSE OF REVIEW: Central venous catheterization (CVC) is a procedure, not exempt of risk. Transplantation patients represent by themselves a high-risk group for CVC. Ultrasonography provides us of the exact localization of the target vein and its relationship with artery and nerve structures, detecting anatomic variations and thromboses of vessels. ...

Neo-intima development and atherosclerosis limit long-term vein graft use for revascularization of ischaemic tissues. Using a rat model, which is technically less challenging than smaller rodents, we provide evidence that the temporal morphological, cellular, and key molecular events during vein arterialization resemble the human vein graft adaptation. Right jugular vein ...
