A circulatory anastomosis is a connection (an anastomosis) between two blood vessels, such as between arteries (arterio-arterial anastomosis), between veins (veno-venous anastomosis) or between an artery and a vein (arterio-venous anastomosis). An end artery (or terminal artery) is an artery that is the only supply of oxygenated blood to a portion of tissue. Examples of an end artery include the splenic artery that supplies the spleen and the renal artery that supplies the kidneys.

Cardiac tamponade is a medical emergency that requires urgent drainage of the pericardial fluid. Preferably, patients should be monitored in an intensive care unit. All patients should receive the following: Oxygen Volume expansion with blood, plasma, dextran, or isotonic sodium chloride solution, as necessary, to maintain adequate intravascular volume - Sagristà-Sauleda et al noted significant increase in cardiac output after volume expansion [24] (see the Cardiac Output calculator) Bed rest with leg elevation - This may help increase venous return Positive-pressure mechanical ventilation should be avoided because it may decrease venous return and aggravate signs and symptoms of tamponade. Inpatient care After pericardiocentesis, leave the intrapericardial catheter in place after securing it to the skin using sterile procedure and attaching it to a closed drainage system via a 3-way stopcock. Periodically check for reaccumulation of fluid, and drain as needed. The catheter can be left in place for 1-2 days and can be used for pericardiocentesis. Serial fluid cell counts can be useful for helping to discover an impending bacterial catheter infection, which could be catastrophic. If the white blood cell (WBC) count rises significantly, the pericardial catheter must be removed immediately. A Swan-Ganz catheter can be left in place for continuous monitoring of hemodynamics and to assess the effect of reaccumulation of pericardial fluid. A repeat echocardiogram and a repeat chest radiograph should be performed within 24 hours.

Ambiguous genitalia is a medical emergency and requires urgent assessment by a paediatrician. If you have sufficient clinical experience, an orogastric tube should be passed when the neonate's mother has suffered polyhydramnios. This excludes oesophageal atresia.

A meningioma is a tumor that arises from the meninges — the membranes that surround your brain and spinal cord. Most meningiomas are noncancerous (benign), though rarely a meningioma may be cancerous (malignant). Some meningiomas are classified as atypical, meaning they're neither benign nor malignant but, rather, something in between.

Sacrococcygeal teratoma (SCT) is an unusual tumor that, in the newborn, is located at the base of the tailbone (coccyx). This birth defect is more common in female than in male babies. Although the tumors can grow very large, they are usually not malignant (that is, cancerous).
