Bronchonoscopy lavage for diagnoses of lung cancer?

Test: This is like the pap smear that check women for cancer of the cervix in that the pathologists looks for malignant cells in the washings obtained from the procedure. A negative result does not rule out malignancy however. ...Read more

Lung (Definition)

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more

Which procedure does a lung perfusion scan involve?

Which procedure does a lung perfusion scan involve?

Inject radioactive: A perfusion lung scan is done by injectecting a low-dose radioactive tracer into a vein and taking images showing where blood flow is going in the lungs. It is used to diagnose pulmonary embolism (blood clot to the lungs). The test is safe and generally free of any side effects. It is used less often now than ct angiogram, but is safer and involves less radiation exposure. ...Read more

Ct scan.Minimal air trappin at lung bases.mild pectus enteric assessment.Bladder wall thickening.L.ovarian functional cyct 3.4 .plz Explaination drs.

Nothing acute : Air trapping indicates something like asthma or COPD. Pectus implies a curve in sternum or breast bone. Bladder wall thickness may be due to partially distended. Small ovarian cyst normal for women your age. Enteric assessment evaluate stomach. Should talk to your doctor ...Read more

Cough: Good question. If the xray is normal, it means you dont have a pneumonia. You could still have bronchitis or cough asthma as causes for the cough. You may need to see a pukmonologist ...Read more

Bronchoscopy with biopsy of lung nodules was done, biopsy result shows normal bt bronchial washing shows poorly differentiate cancer, confused?

Bronchoscopy with biopsy of lung nodules was done, biopsy result shows normal bt bronchial washing shows poorly differentiate cancer, confused?

See below: I'm not sure how your procedure was done, but nodules can be very difficult to biopsy, depending on size and if any type of imaging guidance is used. So in your case, the biopsy may have only gotten normal lung tissue and the nodule itself wasn't biopsied. The washing gets a large area - normal tissue and where the nodules are. It is sent for cytology. the Biopsy would be for histology. ...Read more

Very very mild: You have anatomic emphysema but no functional impairment thus it's very, very mild. If you smoke, please stop. Consider whether you have occupational exposure to toxic fumes? If no to both, you should be checked for alpha-1 antitrypsin deficiency. ...Read more

Adenocarcinoma pressing on the left main stem bronchus. Pulmonologist recommends an endobronchial stent and/or targeted radiation. Thoughts?

Adenocarcinoma pressing on the left main stem bronchus. Pulmonologist recommends an endobronchial stent and/or targeted radiation. Thoughts?

There are >1 choices: Your case can be best managed by a team of oncologists working together. A medical oncologist can/ should coordinate your management. Radiotherapy alone or in combination with chemotherapy may be the best choice. Stenting is an option which is best kept to later use when there is no other treatment options. Right now you need treatment for cancer in addition to mechanical help which is all stent d. ...Read more

My spirometry:slight restrictive shape of curve.Moderate expiratory limitation.Examination for extrathoracic obstruction & expiratory trachealstenosis?

My spirometry:slight restrictive shape of curve.Moderate expiratory limitation.Examination for extrathoracic obstruction & expiratory trachealstenosis?

HRCT: Extrathoracic obstruction may result in changes in airflow both on inspiration and expiration depending on where the obstruction is located. If your physician is investigating an extrathoracic cause, an HRCT is indicated. Sometimes enlarged lymph nodes may impinge on the airway as one possible cause. The restriction is mild and may be due to a number of causes such as fibrosis or scarring. ...Read more

Possible: A reduced DLCO/Va points to damage or scarring in the lung tissue and emphysema (especially if you have been a smoker) or other interstitial lung diseases may be the cause. The normal lung function however is not compatible with COPD but then I don't understand what you meant by hyperinflation in the presence of normal lung function test. See a pulmonologist. ...Read more

Targeted therapy: Newer targeted therapy agents can be quite beneficial for some patients with lung cancer. This is especially true in female never smokers who may have selected mutations that can be easily targeted with these drugs. However, unfortunately stage IV lung cancer is not curable. ...Read more

No pleural mass in chest CT scan,clear pleural exudate (lab results say it is exudate not transudate).No fever or cough. Rule out lung cancer?

Lung Cancer unlikely: In a 30 year old, Lung cancer is not a likely cause of pleural effusion. Depending on other test results and symptoms(?any Fever), TB is one diagnosis high on the list. Your doctor should do further testing for TB and you may need emiric Anti-TB treatment if your fluid keeps reaccumulating or if you have fever on an ongoing basis and if there is significant weight loss. ESR is a useful test to do. ...Read more

Diagnostic assessment before fontan operation in patients with bidirectional cavopulmonary anastomosis: are noninvasive methods sufficient?

Diagnostic assessment before fontan operation in patients with bidirectional cavopulmonary anastomosis: are noninvasive methods sufficient?

Not traditionally: I don't believe so. There may be some programs that will experiment with noninvasive pre-fontan imaging, but i believe that this is risky. The pressures are obtainable only by catheterization and this data may change the operation (e.g., whether or not to fenestrate the fontan to allow a pop-off of blue blood to increase the cardiac output.) catheterization also allows presurgical interventions. ...Read more

Chest XRay - Latetal view demonstrates blunting of both costophrenic angles w/either small lung base pleural effusions are chronic pleural thickening.

If you have: previous chest X-rays to compare, that would be helpful in making the determination between mild pleural thickening(scarring) or effusion(fluid). There are numerous potential etiologies for each. Further imaging could include ultrasound, special chest xray views(decubitus views ), or CT scan. ...Read more

What is a primary lung infection with slight regression hyperaerated lung fields?

What is a primary lung infection with slight regression hyperaerated lung fields?

Pneumonia: Primary lung infection most commonly means pneumonia. Regression means that the infection has decreased since the last study. Hyperaerated lungs can mean that the patient took an intentional deep inspiration or that there is air trapping due to airway blockage, which can be due to asthma, COPD, and other causes. ...Read more
