A 6-month-old female infant, with a birth weight of 2.74 kilograms, was born with multiple congenital abnormalities, including gastric and gastrointestinal defects. She was admitted to the hospital with hematemesis. The patient could not be fed orally, and parenteral nutrition was initiated through a central venous catheter. Following pyloroplasty, she developed superior vena cava syndrome, renal disfunction and episodes of sepsis. Stool and respiratory specimens were negative for fungi, but four blood cultures yielded Hansenula anomala var. anomala. Cultures for fungi from intravenous catheter tips were negative. The baby was treated with amphotericin B (am B) and 5-fluorocytosine (5-FC), (amB; 0.1 mg/kg body weight and 5-FC, 100 mg, q.i.d.). The minimal inhibitory concentrations of am B, 5-FC, am B + 5-FC (1:1, w:w) and fluconazole to H. anomala were 1.56, less than 0.195, 1.56, and 1.56 micrograms, respectively. Following antifungal therapy and removal of the catheter, the patient tolerated oral feeding and, at the time of discharge, her weight had increased to 4.91 kg. This report records H. anomala as an opportunistic yeast pathogen for the first time in Alberta, Canada. Previously published cases of H. anomala infections are reviewed.

Oncology represents a very wide field of applications in interventional radiology. Procedures are diagnostic as well as therapeutic; approaches may be endovascular (either arterial or venous), endocanalar, or transcutaneous; guidance may need X-ray, sonographic, CT scan or endoscopic control. Such a diversity in methods makes clinical and technical training especially long. Main indications of endoarterial approaches are: pain, bleeding, abnormal secretion (endocrine tumors and paraneoplastic syndrome), abnormal function (kidney, spleen), preoperative devascularization of tumors, redistribution of arterial flows before intra arterial chemotherapy, chemoembolizations. Venous pathology is known to be particularly frequent in oncology. Current indications are inferior vena cava filter placement, angioplasty and stenting in case of superior vena cava syndrome, local fibrinolysis, foreign bodies extraction. Drainages, stenosis dilations and stent placements are daily procedures in urinary and biliary tracts in order to treat obstructions, sepsis or fistulas. Transcutaneous approaches under radiological guidance allow biopsies, drainage of deep collections, antalgic nerve infiltrations, gastrostomy. Nowadays, interventional radiology can be considered as a requisite weapon for a correct cancerous patient management, since it is useful from the initial diagnostic biopsy to the palliative care of cancer complications.

We performed a retrospective review of echocardiographic data files of infants and children hospitalized in the Newborn and Pediatric Intensive Care Units. Echocardiograms were examined to detect the presence and evolution of great vein and right atrial thrombosis in patients with central venous lines. Thirty-seven patients were identified over a five-year period. Echocardiograms were performed, not routinely, but in response to specific indications including catheter malfunction, thrombocytopenia, persistent chylothorax, bacterial or fungal sepsis, and superior vena cava syndrome. Fifteen of 37 patients died, 13 of them during the hospitalization in which the thrombus was discovered. Thrombolytic agents and surgery were used to treat selected patients, with mixed results. Two of the 22 survivors have significant disability related to the thrombus or complications arising from it. We conclude that great vein and/or right atrial thrombosis is a common complication of central venous catheterization in small infants and children; moreover, the morbidity and mortality relating to this complication is substantial.

Utilization of endocavitary defibrillation electrodes avoids thoracotomy used in implantable cardioverter-defibrillator procedures, reducing associated morbi-mortality. In our institution we have used this approach in 16 patients during a two years period (July 1990-July 1992). Fifteen were males, with a mean age of 56.9 +/- 10.6 (range 32-73). Nine patients suffered ischemic cardiomyopathy, 4 non ischemic cardiomyopathy and in three there was no structural heart disease. Mean ejection fraction was 44.3 +/- 18.3% (range 20-73%). Clinical arrhythmia was ventricular tachycardia in 8 cases, ventricular fibrillation in 6 cases and both types in 2. Endocavitary implantation procedure was not completed in 3 patients, thus an open trans-sternal approach was performed. In 13 patients it was completed successfully, using a total amount of 14 units (1 patient required two procedures due to sepsis in the generator pouch). Most important intraoperative incidences have been defibrillation thresholds between 20-24 J in 4 cases, displacement of defibrillation electrode from vena cava into coronary sinus in 4 cases, epicardial patch implantation via subcostal approach in 1 case and right ventricle perforation in 1 case. No operative mortality was registered. One patient suffered sudden death during follow-up. Surgical complications were few: 1 case of lead dislodgement and 1 infected wound in the generator's pouch. Non-surgical complications were also few: 1 case with superior vena cava syndrome and 1 patient with inadequate discharges. In conclusion, due to our early experience, we believe that endocavitary implantation of an implantable cardioverter-defibrillator is the procedure of choice at the present time.

Between March 1982 and June 1992, 17 patients (age: 21-76 years) were diagnosed with pseudoaneurysm of the thoracic aorta (PTA). Four PTAs developed post-trauma while 13 developed after aortic or cardiac surgery. Unusual presentations included: dyspnea, hoarseness, dysphagia, massive hemoptysis (2 degrees to aortobronchial fistula), massive hematemesis (2 degrees to aorto-esophageal fistula), superior vena cava syndrome, paralyzed right hemidiaphragm, and herald bleeding from the sternotomy. The interval between initial operation and recognition of PTA varied from three months to eight years while the four posttraumatic PTAs presented 5 to 26 years postinjury. The sites of postoperative PTA were: the aortotomy (3), proximal vein graft anastomosis (4), aortic cannulation site (2), and distal anastomosis of ascending aortic graft replacement (4). Aortography was very sensitive, outlining the false aneurysm in 13/13. Five patients had transesophageal echo-cardiography with one false negative. Seven patients died (41%), three from postoperative PTAs from massive hemorrhage intraoperatively and four from sepsis and multiorgan failure following repair. We conclude that patients who have previously had aortic or cardiac surgery or a history of blunt chest trauma presenting with unusual cardiorespiratory symptoms should be aggressively evaluated for PTA. Due to the magnitude of the operative problems encountered, repair of PTA is associated with a significantly high rate of mortality.

Superior vena cava syndrome is rare in infants, and rarely responds to conservative treatment. We report a 22-mo-old girl with superior vena cava syndrome due to the use of a central venous line and/or sepsis. Doppler study and computed tomography angiography of the neck showed thrombosis within the superior vena cava and jugular veins. She was admitted to a monitored setting and received recombinant tissue plasminogen activator for 2 d. The clinical features of superior vena cava syndrome disappeared completely 3 d after treatment. No complications were observed and radiological investigations showed blood flow through the thrombus after treatment. Systemic recombinant tissue plasminogen activator may be useful in the treatment of superior vena cava syndrome in children.

We present a 2-month-old male infant with thrombosis in the superior vena cava and pericardium due to transient protein C deficiency. Protein C deficiency was related to sepsis and hepatitis-induced liver function impairment. The patient's cardiac anatomy was otherwise normal. The patient was referred to us with signs of superior vena cava syndrome. Pericardial mass was excised. Pathological examination diagnosed the mass as organized thrombus. After the operation, signs of superior vena cava syndrome totally resolved. Serial echocardiographic examinations revealed regression of thrombus in the superior vena cava. This is the first case reported in the literature with intrapericardial thrombus secondary to transient protein C deficiency.

Central venous occlusion in children is a challenging problem that can occur after a central venous catheter insertion. Long-term catheter-related complications include sepsis and venous thrombosis with consequent loss of central access. We describe 2 cases of children younger than 1 year who were dependent on a central venous catheter for total parenteral nutrition. They developed a chronic extensive obstruction of the right and left brachiocephalic veins with a superior vena cava syndrome. The patients' survival was dependent on the restoration of central venous access until the planned intestinal transplantation could be performed. Retrograde recanalization of the superior vena cava was successfully achieved using a pathway created under general anesthesia from the femoral vein to, respectively, the right thyroid vein and the right subclavian vein.

The picture of oncologic emergencies in the intensive care unit has changed over the past decade. The classic emergencies, that is, superior vena cava syndrome, spinal cord compression, tumor lysis syndrome and life-threatening hypercalcemia, are now routinely managed on the general oncology unit or in an outpatient setting. Vigilant monitoring for early signs of complications, proactive interventions to prevent complications, and aggressive management account for this change. Currently, emergent conditions that necessitate intensive care unit admission or transfer in the patient with cancer include respiratory failure, cardiac emergencies, hemorrhagic events and coagulopathies, sepsis, and hemodynamic instability. This article will present the current evidence-based management of these conditions, a brief summary of classic oncologic emergencies, and the role of the critical care nurse in meeting the multidimensional needs of the patient and family during the life-threatening episode, based on Ferrell's quality of life model.
