Paradoxical systemic embolization in hereditary hemorrhagic telangiectasia.
A 53-year-old man presented with sudden onset left-sided weakness. His medical history included hereditary hemorrhagic telangiectasia with recurrent epistaxis. On examination, he was hypoxemic at rest and had left-sided flaccid hemiparesis. He was noted to have multiple lower lip telangiectasias (Figure 1). Computed tomography of chest revealed bilateral segmental and subsegmental pulmonary emb...
متن کاملPatent foramen ovale and paradoxical embolization: a historical perspective.
The use of transesophageal echocardiography for intraoperative management of critically ill patients allows for routine evaluation of foramen ovale patency. The high prevalence of preoperatively unrecognized flow-patency of this structure has led investigators to emphasize the potential for paradoxical embolization in any patient undergoing anesthesia. This perspective led us to research earlie...
متن کاملParadoxical cerebral arterial embolization of cement during intraoperative vertebroplasty: case report.
Paradoxical cerebral embolism of cement occurred in a 78-year-old woman after cement-assisted transpedicular spinal fixation surgery. Multiple pulmonary emboli of polymethylmethacrylate precipitated pulmonary hypertension and right-to-left shunting into the systemic circulation through a patent foramen ovale. This rare complication occurred because of failure to recognize venous migration of ce...
متن کاملDetection of paradoxical cerebral echo contrast embolization by transcranial Doppler ultrasound.
Contrast echocardiography has been shown to be a sensitive method for detecting patent foramen ovale in embolic stroke, implying paradoxical embolization. However, not all two-dimensional echocardiographic studies are of diagnostic quality, and direct evidence for paradoxical cerebral embolization remains lacking. We addressed these problems by simultaneously using transcranial Doppler ultrasou...
متن کاملParadoxical embolization in TIPS: take a closer look to the heart.
No definitive indications are provided in the literature for pre-TIPS patient workup, which is often limited to prevent the incidence of refractory hepatic encephalopathy or unacceptable deterioration of liver function. Concerning cardiologic workup, efforts are generally limited at excluding ventricular failure or porto pulmonary hypertension. The cases presented herein focus the attention of ...
