Background: Symptomatic pleural effusion following ventriculoperitoneal shunt (VPS) insertion is very rare and poorly understood in the literature in contrary to other mechanical complications. Case Description: We report a case of 15 month-year-old girl who had VP shunt for congenital hydrocephalus. Twelve months after surgery, she was diagnosed with massive hydrothorax. Chest X-ray and thoracoabdominal CT scan confirmed the right pleurisy and showed the tip of the peritoneal catheter in the general peritoneal cavity. We made thoracic drainage of the transudative pleural effusion. When we released the chest tube, 24 h after, the girl showed a respiratory distress again and the effusion resumed at the X-ray control. Her symptoms abated after the realization of a ventriculoatrial shunt "VAS." Repeat chest X-ray confirmed the resolution of the hydrothorax. Conclusion: Despite the not yet well-understood mechanism of this rare and important VPS complication, management is simple based on X-ray confirmation, thoracentesis with biological analysis, and catheter replacement, especially in atrium "VAS.".

Cerebral air embolism due to pulmonary tuberculosis is an extremely rare cause of stroke. We report an unusual case of a presentation of cerebral air embolism likely due to pulmonary tuberculosis lesions during a severe cough. We discuss the relationship between the pulmonary tuberculosis and the occurrence of the cerebral air embolism. A 55-year-old man with lung tuberculosis suddenly experienced a nontraumatic loss of consciousness after a severe cough. The magnetic resonance imaging confirmed an ischemic stroke due to cerebral air embolism. The thoracic scan revealed tuberculosis with a parenchymatous cavity. Patients with intrapulmonary tuberculosis cavities should be strongly considered for surgical repair and should be warned about the risk of rupture of the cavity in the situation of increasing thoracic pressure.

This study was designed to determine the efficacy of oral etilefrine in preventing hypotension induced by spinal anaesthesia. Forty patients, ASA grade I or II, aged 23–60 years, scheduled for orthopaedic surgery involving the lower extremity under spinal anaesthesia were studied. The patients were randomly allocated to one of two groups; the etilefrine group (n = 20) received oral etilefrine 15 mg (30 drops), 60 min before the subarachnoid block, and the control group (n = 20) received no etilefrine. Patients were given 0.5% isobaric bupivacaine intrathecally. Hypotension was defined as a 30% decrease from base-line for systolic arterial pressure and mean arterial pressure or systolic value <90 mmHg, and was treated with intravenous boluses of etilefrine 2 mg. The overall incidence of spinal anaesthesia induced hypotension was 25%, ranging from 20% in the etilefrine group to 30% in the control group. The fall in systolic arterial pressure and mean arterial pressure was significantly greater in the control group than in the etilefrine group (P < 0.05). The patients in the etilefrine group received less etilefrine supplement than those in control group and no subject in the etilefrine group required repeat etilefrine doses, while in the control group five patients received multiple etilefrine doses (P < 0.05). The mean heart rate remained fairly stable throughout the study periods. We conclude that oral etilefrine, given 60 min before surgery, reduces the fall in blood pressure during spinal anaesthesia.
