Acute stroke after coronary angiography associated with protruding mobile thoracic aortic atheromas.

We describe two patients who developed acute embolic stroke immediately after coronary catheterization for unstable angina. Transesophageal echocardiography (TEE) and spiral CT of the chest revealed protruding floating atheromas within the aortic arch. These cases of stroke immediately after coronary catheterization suggest that protruding floating atheromas of the thoracic aorta place patients at risk for stroke. TEE or CT might predict a risk of stroke in such patients.

[Extensive postpartum, bilateral ovarian vein thrombosis].

A 29-year-old woman with extensive pelvic thrombophelebitis complicating postpartum, ovarian vein thrombosis is described. The phlebitic process involved both ovaries, extending upwards to the inferior vena cava above the level of the renal veins and downwards to the ileo-femoral system, obstructing the venous drainage of the lower limbs. Extensive postpartum thrombophlebitis is now rarely encountered, since its early clinical diagnosis using CT and US techniques allows early treatment, obviates this complication. Postpartum bedside alertness, aided by modern imaging techniques, may prevent serious, life-threatening complications.

[Pulmonary sequestration detected by ultrasound].

Pulmonary sequestration is part of the spectrum of bronchopulmonary foregut anomaly. It is a rare type of congenital malformation in which a mass of pulmonary tissue is separate from the normal lung and receives its arterial supply directly from the systemic circulation. Angiographic demonstration of a systemic artery leading to the sequestrated lung has usually been used to diagnose this condition. In the past 10 years cases of this rare anomaly have been detected and diagnosed by ultrasonography in the pre- and postnatal period. We describe a very rare case of intraabdominal, extralobar pulmonary sequestration detected in the antenatal period. Ultrasonography showed a hyperechoic subdiaphragmatic mass above the left kidney, near the aorta. In the mass were 2 echo-free vascular structures. 2 arterial branches originating from the abdominal aorta which traversed the subdiaphragmatic mass. The near-diaphragmatic location of many pulmonary sequestrations provides an excellent acoustic window for sonographic detection. MRI can help in the diagnosis when ultrasonographic findings are equivocal. Ultrasound and MRI will soon replace aortic angiography in the diagnosis of this condition in the pre- and postnatal period, pulmonary sequestration should be included in the differential diagnosis of upper abdominal masses identified by ultrasonography.

[Endoscopic drainage of pancreatic pseudocyst: endoscopic cysto-enterostomy].

Pancreatic pseudocysts occur in 20% of cases of chronic pancreatitis. Spontaneous resolution is seen in about 9% of the cases, but most cysts persist and frequently cause complications, such as compression of adjacent organs or infection. Endoscopic cysto-enterostomy has recently been reported as a new nonsurgical invasive approach. We present a 40-year-old alcoholic man with a large pancreatic pseudocyst compressing the distal choledochus and pancreatic duct, who was treated successfully by endoscopic cysto-duodenostomy.
