Bileaflet mechanical prostheses for aortic valve replacement in patients younger than 65 years and 65 years of age or older: major thromboembolic and hemorrhagic complications. (1/2752)OBJECTIVE: To determine major thromboembolic and hemorrhagic complications and predictive risk factors associated with aortic valve replacement (AVR), using bileaflet mechanical prostheses (CarboMedics and St. Jude Medical). DESIGN: A case series. SETTING: Cardiac surgical services at the teaching institutions of the University of British Columbia. PATIENTS AND METHODS: Patients 2 age groups who had undergone AVR between 1989 and 1994 were studied. Group 1 comprised 384 patients younger than 65 years. Group 2 comprised 215 patients 65 years of age and older. RESULTS: The linearized rates of major thromboembolism (TE) occurring after AVR were 1.54%/patient-year for group 1 and 3.32%/patient-year for group 2; the rates for major TE occurring more than 30 days after AVR were 1.13%/patient-year for group 1 and 1.55%/patient-year for group 2. The crude rates for major TE occurring within 30 days of AVR were 1.04% for group 1 and 3.72% for group 2. The death rate from major TE in group 1 was 0.31%/patient-year and in group 2 was 0.88%/patient-year. Of the major TE events occurring within 30 days, 100% of patients in both age groups were inadequately anticoagulated at the time of the event, and for events occurring more than 30 days after AVR, 45% in group 1 and 57% in group 2 were inadequately anticoagulated (INR less than 2.0). The overall linearized rates of major hemorrhage were 1.54%/patient-year for group 1 and 2.21%/patient-year for group 2. There were no cases of prosthesis thrombosis in either group. The mean (and standard error) overall freedom from major TE for group 1 patients at 5 years was 95.6% (1.4%) and with exclusion of early events was 96.7% (1.3%); for group 2 patients the rates were 90.0% (3.2%) and 93.7% (3.0%), respectively. The mean (and SE) overall freedom from major and fatal TE and hemorrhage for group 1 patients was 90.1% (2.3%) and with exclusion of early events was 91.2% (2.3%); for group 2 patients the rates were 87.9% (3.1%) and 92.5% (2.9%), respectively. The 5-year rate for freedom from valve-related death for group 1 patients was 96.3% (2.1%) and for group 2 patients was 97.2% (1.2%). CONCLUSION: The thromboembolic and hemorrhagic complications after AVR with bileaflet mechanical prostheses occur more frequently and result in more deaths in patients 65 years of age and older than in patients years younger than 65 years.

Evaluation of the allograft-prosthesis composite technique for proximal femoral reconstruction after resection of a primary bone tumour. (2/2752)OBJECTIVE: To evaluate clinical and functional outcomes resulting from the allograft-composite technique used for proximal femoral osteoarticular reconstruction in patients who had limb salvage surgery for primary bone tumours. DESIGN: A retrospective review of a prospectively gathered database to provide a descriptive study. SETTING: A tertiary care musculoskeletal oncology unit in a university hospital. PATIENTS AND INTERVENTIONS: Patients treated between 1987 and 1993 were eligible for inclusion in this study if they met the following criteria: they were treated surgically for a primary malignant bone tumour; and a proximal femoral allograft-implant composite technique was used for the reconstruction. MAIN OUTCOME MEASURES: Major postoperative complications with emphasis on mechanical complications in the reconstructive composite implant. Functional outcome in a subset of patients using the 1987 and 1994 versions of the Musculoskeletal Tumor Society instrument, the Short-Form-36 and the Toronto Extremity Salvage Score. RESULTS: There were 5 mechanical and 2 infectious complications requiring surgical intervention. Functional scores were generally low. CONCLUSIONS: Our results suggest that the perceived benefits of the composite technique may accrue only to a few patients, partly owing to the risk of mechanical complications. Although these can be reduced by avoiding the use of cement in the host femur, the generally poor functional outcomes suggest that this technique needs to be studied further in this group of patients and compared with other reconstructive techniques, particularly the prosthetic implant.

Factors influencing the development of vein-graft stenosis and their significance for clinical management. (3/2752)OBJECTIVES: To assess the influence of clinical and graft factors on the development of stenotic lesions. In addition the implications of any significant correlation for duplex surveillance schedules or surgical bypass techniques was examined. PATIENTS AND METHODS: In a prospective three centre study, preoperative and peroperative data on 300 infrainguinal autologous vein grafts was analysed. All grafts were monitored by a strict duplex surveillance program and all received an angiogram in the first postoperative year. A revision was only performed if there was evidence of a stenosis of 70% diameter reduction or greater on the angiogram. RESULTS: The minimum graft diameter was the only factor correlated significantly with the development of a significant graft stenosis (PSV-ratio > or = 2.5) during follow-up (p = 0.002). Factors that correlated with the development of event-causing graft stenosis, associated with revision or occlusion, were minimal graft diameter (p = 0.001), the use of a venovenous anastomosis (p = 0.005) and length of the graft (p = 0.025). Multivariate regression analysis revealed that the minimal graft diameter was the only independent factor that significantly correlated with an event-causing graft stenosis (p = 0.009). The stenosis-free rates for grafts with a minimal diameter < 3.5 mm, between 3.5-4.5 and > or = 4.5 mm were 40%, 58% and 75%, respectively (p = < 0.05). Composite vein and arm-vein grafts with minimal diameters > or = 3.5 mm were compared with grafts which consisted of a single uninterrupted greater saphenous vein with a minimal diameter of < 3.5 mm. One-year secondary patency rates in these categories were of 94% and 76%, respectively (p = 0.03). CONCLUSIONS: A minimal graft diameter < 3.5 mm was the only factor that significantly correlated with the development of a graft-stenosis. However, veins with larger diameters may still develop stenotic lesions. Composite vein and arm-vein grafts should be used rather than uninterrupted small caliber saphenous veins. (+info)
Frame dislocation of body middle rings in endovascular stent tube grafts. (4/2752)OBJECTIVES: To understand the cause, and propose a mechanism for frame dislocation in endovascular grafts. MATERIALS AND METHODS: Five tube grafts were explanted due to secondary distal leakage 15-21 months after operation. One bifurcated graft was removed during emergency operation after aortic rupture caused by secondary leakage. A second bifurcated graft was harvested from a patient with thrombotic occlusion of one limb, who died after transurethral prostatic resection. The inside of the grafts were examined endoscopically. The stent was inspected after removal of the fabric, broken ligatures were counted and examined by scanning electron microscopy. The fabric strength was tested by probe puncture. RESULTS: We found 17-44% of the stent ligatures of the body middle rings to be loose. The knots were intact. Degradation of the polyester textile was not observed. CONCLUSIONS: Continuous movements in the grafted aorta and blood pressure impose permanent stress to the stent frame and the polyester fabric resulting in morphological changes in the body middle ring of grafts. The clinical implications of the suture breakages are unknown although they may be related to distal secondary leakage in tube grafts. (+info)
Experimental assessment of proximal stent-graft (InterVascular) fixation in human cadaveric infrarenal aortas. (5/2752)OBJECTIVES: This paper investigates the radial deformation load of an aortic endoluminal prosthesis and determines the longitudinal load required to cause migration in a human cadaveric aorta of the endoprosthesis. DESIGN AND METHODS: The endovascular prosthesis under investigation was a 24 mm diameter, nitinol, self-expanding aortoaortic device (InterVascular, Clearwater, Florida, U.S.A.). Initially, a motorised digital force gauge developed an incremental load which was applied to the ends of five stent-grafts, to a maximum of 10 mm (42%) compression. Secondly, using a simple bench model, each ends of four stent-grafts were deployed into 10 cadaveric experimental aneurysm necks and a longitudinal load applied to effect distraction. RESULTS: Increasing load produced increasing percentage deformation of the stent-grafts. The mean longitudinal distraction load for an aneurysm neck of 20 mm was 409 g (200-480 g), for 15 mm was 277 g (130-410 g) and for 10 mm was 218 g (130-340 g). The aneurysm diameter and aortic calcification had p values of 0.002 and 0.047, respectively, while the p value for aneurysm neck length was less than 0.00001. CONCLUSIONS: These results suggest that there is a theoretical advantage of oversizing an aortic prosthesis and that sufficient anchorage is achieved in an aortic neck of 10 mm to prevent migration when fully deployed.

Fate of endoleaks after endoluminal repair of abdominal aortic aneurysms with the EVT device. (6/2752)OBJECTIVE: we aim to describe our medium-term follow-up of 20 patients with an endoleak following repair of their abdominal aortic aneurysms (AAA) using the Endovascular Technologies (EVT) device. DESIGN: the experience of one centre in a prospective multicentre phase II trial. MATERIALS AND METHODS: 55 patients with an endovascular repair of their AAA and at least 6 months>> follow-up were reviewed. Intraoperative angiograms, next day duplex scans and computed tomography (CT) images were used to detect endoleaks. Follow-up with CT and duplex was performed at 3, 6, 12 and 24 months. Persistent endoleaks at 6 months were evaluated by angiography and treated by endovascular coiling. RESULTS: there were three immediate conversions to open procedures. Twenty of 52 (38%) patients had an endoleak identified initially. One patient died from a myocardial infarction and three were not evident any longer by discharge CT. Sixteen endoleaks (31%) were present at discharge. Nine resolved spontaneously by 3-6 months and seven were still persistent at 6 months (14%). Six patients underwent coiling of their leak, all with successful radiographic seal after 1-3 sessions. CONCLUSIONS: endoleaks are frequent after endovascular AAA repair, but the majority close spontaneously. Coiling of the leaks and radiographic seal can be achieved in all cases still persistent at 6 months. Whether this method is clinically effective awaits further follow-up. (+info)
Management of a rare complication of endovascular treatment of direct carotid cavernous fistula. (7/2752)A 30-year-old woman with direct carotid cavernous fistula underwent endovascular treatment with detachable balloons via a transarterial route. The patient returned with diplopia 1 year after therapy. On cranial MR imaging, one of the balloons was detected in the proximal portion of the superior ophthalmic vein and was deflated percutaneously with a 22-gauge Chiba needle under CT guidance. The patient's symptoms resolved after balloon deflation. This case report presents a unique complication of endovascular treatment of direct carotid cavernous fistula and its management. (+info)
Is there a need for routine testing of ICD defibrillation capacity? Results from more than 1000 studies. (8/2752)AIMS: Benefits and complications of postoperative implantable cardioverter-defibrillator tests are controversial matters. This study sought to assess the necessity of defibrillation function tests after implantation. METHODS AND RESULTS: We retrospectively analysed 1007 implantable cardioverter-defibrillator tests in 587 systems and 556 patients. Nine hundred and thirty implantable cardioverter-defibrillator tests (89.4%) were routinely performed. Seventy-one tests (7%) were performed after a change in the antiarrhythmic drug regimen and six tests (0.60%) because of a suspected dysfunction of the implantable cardioverter-defibrillator. During routine tests, four systems (0.4%) failed to defibrillate the patient. However, in all but one test, abnormalities of the system had been observed before the test. After the addition of antiarrhythmic drugs, two of 71 implantable cardioverter-defibrillator systems (2.8%) failed to defibrillate the patient. One of six systems tested due to a suspected dysfunction failed to defibrillate the patient. During 16 tests (1.6%), complications occurred. CONCLUSIONS: Our experience demonstrates that postoperative tests of the defibrillation function of implantable cardioverter-defibrillators rarely reveal dysfunctions. As testing is unpleasant for the patient and not free of complications, tests might be restricted to those patients in whom a dysfunction is suspected and to those patients in whom class I or class III antiarrhythmic drugs have been added to the antiarrhythmic drug regimen.

There are two main types of heart failure:
1. Left-sided heart failure: This occurs when the left ventricle, which is the main pumping chamber of the heart, becomes weakened and is unable to pump blood effectively. This can lead to congestion in the lungs and other organs.
2. Right-sided heart failure: This occurs when the right ventricle, which pumps blood to the lungs, becomes weakened and is unable to pump blood effectively. This can lead to congestion in the body's tissues and organs.
Symptoms of heart failure may include:
* Shortness of breath
* Swelling in the legs, ankles, and feet
* Swelling in the abdomen
* Weight gain
* Coughing up pink, frothy fluid
* Rapid or irregular heartbeat
* Dizziness or lightheadedness
Treatment for heart failure typically involves a combination of medications and lifestyle changes. Medications may include diuretics to remove excess fluid from the body, ACE inhibitors or beta blockers to reduce blood pressure and improve blood flow, and aldosterone antagonists to reduce the amount of fluid in the body. Lifestyle changes may include a healthy diet, regular exercise, and stress reduction techniques. In severe cases, heart failure may require hospitalization or implantation of a device such as an implantable cardioverter-defibrillator (ICD) or a left ventricular assist device (LVAD).
It is important to note that heart failure is a chronic condition, and it requires ongoing management and monitoring to prevent complications and improve quality of life. With proper treatment and lifestyle changes, many people with heart failure are able to manage their symptoms and lead active lives.
A condition in which the kidneys gradually lose their function over time, leading to the accumulation of waste products in the body. Also known as chronic kidney disease (CKD).
Chronic kidney failure affects approximately 20 million people worldwide and is a major public health concern. In the United States, it is estimated that 1 in 5 adults has CKD, with African Americans being disproportionately affected.
The causes of chronic kidney failure are numerous and include:
1. Diabetes: High blood sugar levels can damage the kidneys over time.
2. Hypertension: Uncontrolled high blood pressure can cause damage to the blood vessels in the kidneys.
3. Glomerulonephritis: An inflammation of the glomeruli, the tiny blood vessels in the kidneys that filter waste and excess fluids from the blood.
4. Interstitial nephritis: Inflammation of the tissue between the kidney tubules.
5. Pyelonephritis: Infection of the kidneys, usually caused by bacteria or viruses.
6. Polycystic kidney disease: A genetic disorder that causes cysts to grow on the kidneys.
7. Obesity: Excess weight can increase blood pressure and strain on the kidneys.
8. Family history: A family history of kidney disease increases the risk of developing chronic kidney failure.
Early stages of chronic kidney failure may not cause any symptoms, but as the disease progresses, symptoms can include:
1. Fatigue: Feeling tired or weak.
2. Swelling: In the legs, ankles, and feet.
3. Nausea and vomiting: Due to the buildup of waste products in the body.
4. Poor appetite: Loss of interest in food.
5. Difficulty concentrating: Cognitive impairment due to the buildup of waste products in the brain.
6. Shortness of breath: Due to fluid buildup in the lungs.
7. Pain: In the back, flank, or abdomen.
8. Urination changes: Decreased urine production, dark-colored urine, or blood in the urine.
9. Heart problems: Chronic kidney failure can increase the risk of heart disease and heart attack.
Chronic kidney failure is typically diagnosed based on a combination of physical examination findings, medical history, laboratory tests, and imaging studies. Laboratory tests may include:
1. Blood urea nitrogen (BUN) and creatinine: Waste products in the blood that increase with decreased kidney function.
2. Electrolyte levels: Imbalances in electrolytes such as sodium, potassium, and phosphorus can indicate kidney dysfunction.
3. Kidney function tests: Measurement of glomerular filtration rate (GFR) to determine the level of kidney function.
4. Urinalysis: Examination of urine for protein, blood, or white blood cells.
Imaging studies may include:
1. Ultrasound: To assess the size and shape of the kidneys, detect any blockages, and identify any other abnormalities.
2. Computed tomography (CT) scan: To provide detailed images of the kidneys and detect any obstructions or abscesses.
3. Magnetic resonance imaging (MRI): To evaluate the kidneys and detect any damage or scarring.
Treatment for chronic kidney failure depends on the underlying cause and the severity of the disease. The goals of treatment are to slow progression of the disease, manage symptoms, and improve quality of life. Treatment may include:
1. Medications: To control high blood pressure, lower cholesterol levels, reduce proteinuria, and manage anemia.
2. Diet: A healthy diet that limits protein intake, controls salt and water intake, and emphasizes low-fat dairy products, fruits, and vegetables.
3. Fluid management: Monitoring and control of fluid intake to prevent fluid buildup in the body.
4. Dialysis: A machine that filters waste products from the blood when the kidneys are no longer able to do so.
5. Transplantation: A kidney transplant may be considered for some patients with advanced chronic kidney failure.
Chronic kidney failure can lead to several complications, including:
1. Heart disease: High blood pressure and anemia can increase the risk of heart disease.
2. Anemia: A decrease in red blood cells can cause fatigue, weakness, and shortness of breath.
3. Bone disease: A disorder that can lead to bone pain, weakness, and an increased risk of fractures.
4. Electrolyte imbalance: Imbalances of electrolytes such as potassium, phosphorus, and sodium can cause muscle weakness, heart arrhythmias, and other complications.
5. Infections: A decrease in immune function can increase the risk of infections.
6. Nutritional deficiencies: Poor appetite, nausea, and vomiting can lead to malnutrition and nutrient deficiencies.
7. Cardiovascular disease: High blood pressure, anemia, and other complications can increase the risk of cardiovascular disease.
8. Pain: Chronic kidney failure can cause pain, particularly in the back, flank, and abdomen.
9. Sleep disorders: Insomnia, sleep apnea, and restless leg syndrome are common complications.
10. Depression and anxiety: The emotional burden of chronic kidney failure can lead to depression and anxiety.
FTT is typically diagnosed when a child's weight or height is below the 10th percentile for their age, and they are not gaining weight or growing at a normal rate despite adequate nutrition and appropriate medical care. This can be caused by a variety of factors, including:
* Poor nutrition or inadequate caloric intake
* Genetic disorders that affect growth
* Chronic illnesses such as asthma, gastrointestinal problems, or heart disease
* Environmental factors such as poverty, neglect, or poor living conditions
* Hormonal imbalances
FTT can have significant long-term consequences for a child's health and development. Children who fail to thrive may be at increased risk for:
* Delayed cognitive and social development
* Behavioral problems such as anxiety or depression
* Poor school performance
* Increased risk of chronic diseases such as obesity, diabetes, and heart disease later in life.
Treatment for FTT depends on the underlying cause and may include:
* Nutritional supplements or changes to the child's diet
* Medical treatment for any underlying chronic illnesses
* Addressing environmental factors such as poverty or neglect
* Hormone replacement therapy if hormonal imbalances are suspected
* Psychosocial interventions to address behavioral problems or other issues that may be contributing to the child's FTT.
It is important for parents and caregivers to monitor their child's growth and development and seek medical attention if they notice any signs of FTT, such as:
* Poor weight gain or growth rate
* Delayed physical milestones such as sitting, crawling, or walking
* Poor appetite or difficulty feeding
* Frequent illnesses or infections.
1. Viral hepatitis (hepatitis A, B, or C)
2. Overdose of medications or supplements
3. Toxic substances (e.g., alcohol, drugs, or chemicals)
4. Sepsis or other infections that spread to the liver
5. Certain autoimmune disorders (e.g., hemochromatosis, Wilson's disease)
6. Cancer that has metastasized to the liver
7. Blood vessel blockage or clotting in the liver
8. Lack of blood flow to the liver
1. Jaundice (yellowing of skin and eyes)
2. Nausea and vomiting
3. Abdominal swelling and discomfort
4. Fatigue, weakness, and loss of appetite
5. Confusion or altered mental state
6. Seizures or coma
7. Pale or clay-colored stools
8. Dark urine
1. Physical examination and medical history
2. Laboratory tests (e.g., liver function tests, blood tests, imaging studies)
3. Biopsy of the liver tissue (to rule out other liver diseases)
1. Supportive care (fluids, nutrition, and medication to manage symptoms)
2. Addressing underlying causes (e.g., stopping alcohol or drug use, treating infections)
3. Transjugular intrahepatic portosystemic shunt (TIPS), a procedure that creates a new pathway for blood to flow through the liver
4. Liver transplantation (in severe cases where other treatments have failed)
The prognosis for acute liver failure depends on the underlying cause of the condition and the severity of the liver damage. In general, the earlier the diagnosis and treatment, the better the outcome. However, acute liver failure can be a life-threatening condition, and the mortality rate is high, especially in cases where there is severe liver damage or no available donor liver for transplantation.
There are several causes of liver failure, including:
1. Alcohol-related liver disease: Prolonged and excessive alcohol consumption can damage liver cells, leading to inflammation, scarring, and eventually liver failure.
2. Viral hepatitis: Hepatitis A, B, and C are viral infections that can cause inflammation and damage to the liver, leading to liver failure.
3. Non-alcoholic fatty liver disease (NAFLD): A condition where there is an accumulation of fat in the liver, leading to inflammation and scarring.
4. Drug-induced liver injury: Certain medications can cause liver damage and failure, especially when taken in high doses or for extended periods.
5. Genetic disorders: Certain inherited conditions, such as hemochromatosis and Wilson's disease, can cause liver damage and failure.
6. Acute liver failure: This is a sudden and severe loss of liver function, often caused by medication overdose or other toxins.
7. Chronic liver failure: A gradual decline in liver function over time, often caused by cirrhosis or NAFLD.
Symptoms of liver failure can include:
1. Jaundice (yellowing of the skin and eyes)
3. Loss of appetite
4. Nausea and vomiting
5. Abdominal pain
6. Confusion and altered mental state
7. Easy bruising and bleeding
Diagnosis of liver failure is typically made through a combination of physical examination, medical history, and laboratory tests, such as blood tests to check for liver enzymes and bilirubin levels. Imaging tests, such as ultrasound and CT scans, may also be used to evaluate the liver.
Treatment of liver failure depends on the underlying cause and severity of the condition. In some cases, a liver transplant may be necessary. Other treatments may include medications to manage symptoms, such as nausea and pain, and supportive care to maintain nutrition and hydration. In severe cases, hospitalization may be required to monitor and treat complications.
Prevention of liver failure is important, and this can be achieved by:
1. Avoiding alcohol or drinking in moderation
2. Maintaining a healthy weight and diet
3. Managing underlying medical conditions, such as diabetes and high blood pressure
4. Avoiding exposure to toxins, such as certain medications and environmental chemicals
5. Getting vaccinated against hepatitis A and B
6. Practicing safe sex to prevent the spread of hepatitis B and C.
The definition of MOF varies depending on the context and the specific criteria used to define it. However, in general, MOF is characterized by:
1. The involvement of multiple organs: MOF affects multiple organs in the body, such as the lungs, liver, kidneys, heart, and brain. Each organ failure can have a significant impact on the individual's overall health and survival.
2. Severe dysfunction: The dysfunction of multiple organs is severe enough to cause significant impairment in the individual's physiological functions, such as breathing, circulation, and mental status.
3. Lack of specific etiology: MOF often occurs without a specific identifiable cause, although it can be triggered by various factors such as infections, injuries, or medical conditions.
4. High mortality rate: MOF is associated with a high mortality rate, especially if left untreated or if the underlying causes are not addressed promptly.
The diagnosis of MOF requires a comprehensive evaluation of the individual's medical history, physical examination, laboratory tests, and imaging studies. Treatment involves addressing the underlying causes, supporting the failing organs, and managing symptoms. The prognosis for MOF depends on the severity of the condition, the underlying cause, and the promptness and effectiveness of treatment.
