We report a rare case of acute mastitis caused by enteric organisms passing through a cystoperitoneal shunt catheter, which had penetrated into the colon. The patient is a 56-year-old woman who underwent shunt placement for cyst formation after surgery for meningioma at the age of 29. After 26 years, she suffered from a brain abscess and an attempt was made to surgically remove the indwelling c...

With the goal of developing a practical method of performing noninvasive measurements of flow in cerebrospinal fluid (CSF) shunts, transcutaneous thermal convection CSF shunt flow measurement was investigated using dimensional analysis, numerical modeling, and bench testing. Using appropriate manufacturing practices and controls, a microcontroller-based device was designed, constructed, and cli...

The ventriculoperitoneal (VP) shunt is a routine procedure for cerebrospinal fluid (CSF) diversion, and is associated with many complications. A delayed hemorrhage after the VP shunt surgery, however, is quite rare. In this study, we report a case involving late-onset hemorrhage. The 67-year-old male patient with a history of head trauma and brain surgery underwent a VP shunt placement for hydr...

background: intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. the aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation.   methods: one hundred and two adult patients underwent contrast...

We report the first European case of cerebral iodized lipid embolism post transcatheter arterial embolization for hepatocellular carcinoma. Lipiodol emboli and corresponding multifocal brain ischemia were documented with computed tomography (CT) and magnetic resonance (MR) in the acutely symptomatic patient. Transcranial Doppler sonography with contrast indicated a right-to-left shunt, while on...

Hydrocephalus is a neurological disease which causes ventricular dilation due to abnormalities in the cerebrospinal fluid (CSF) circulation. Although treatment via a CSF shunt in the brain ventricles has been performed, poor rates of patient responses continue. Thus, to aid surgeons in hydrocephalus treatment planning, we propose a geometric computational approach for tracking hydrocephalus ven...

BACKGROUND Right-to-left vascular shunts are associated with brain abscess. CASE REPORT We present a 47-year-old female with a cryptogenic left thalamic abscess on which Streptococcus mitis grew upon aspiration. Computed tomography of the chest with contrast agent revealed an anomalous connection between the left superior pulmonary and brachiocephalic veins. A right-to-left shunt was confirme...

Cranial CT and high resolution measurements of regional cerebral blood flow (rCBF) with brain dedicated single photon emission computer tomography (SPECT) and [99mTc]-d,l-hexamethylpropyleneamine oxime ([99mTc]-d,l-HMPAO) were performed before and after shunt operation in 14 consecutive patients with dementia and normal pressure hydrocephalus (NPH). When compared with a control group of 14 age ...

Brain edema due to venous thrombosis following stereotactic radiosurgery for a cerebral arteriovenous malformation (AVM) has rarely been reported. We report a patient with a large AVM in the eloquent area, and brain edema developed in this area after repeat Gamma knife stereotactic radiosurgery (GKRS). An 18-year-old female presented with a 4-year-history of persistent headache. Magnetic resona...
