Embolism definition

In paradoxical embolism , also known as crossed embolism, an embolus from the veins crosses to the arterial blood system. This is generally found only with heart problems such as septal defects (holes in the cardiac septum) between the atria or ventricles. The most common such abnormality is patent foramen ovale , occurring in about 25% of the adult population, but here the defect functions as a valve which is normally closed, because pressure is slightly higher in the left side of the heart. Sometimes, for example if a patient coughs just when an embolus is passing, it might cross to the arterial system.

Catheter-directed thrombolysis utilizes a catheter to direct thrombolytics with ultrasound assistance. A 2014 industry-sponsored study evaluated 59 patients with acute PE and RV enlargement based on echocardiogram, with patients randomized to ultrasound-directed thrombolytic with unfractionated heparin and heparin alone. RV dilatation at 24 hours was improved in the catheter-directed thrombolytic group. No bleeding complications were found in the intervention group. 28 The SEATTLE II trial was a multicenter, single-arm trial which evaluated US-facilitated, catheter-directed, low-dose thrombolysis. Investigators included 31 patients with massive PE and 119 patients with submassive PE . Treatment decreased RV dilatation, reduced pulmonary hypertension, decreased clot burden, and minimized risk of ICH . One patient suffered major bleeding with a groin hematoma and transient hypotension. 29

Q. What is the differential diagnosis of chest pain in a 35 year old woman? I am a 35 years old woman. I suffer from chest pain for about 24 hours. I just came back from a trip to Europe, and i feel really bad. I smoke and I take anti contraceptive and i know that I am at a risk for pulmonary embolism or costochondritis. Cat it be something else? A. The differential diagnosis of chest pain is very wide.
It can start in costochondritis if u carried a lot of luggage or might be pulmonary embolism if you didn't move from the chair all the flight. But it can also be a sign for an acute coronary syndrome (even at the age of 35) or a pericarditis. To be sure you need to consult with your GP.

Our current generation of practitioners is fortunate to have a number of options for treatment of pulmonary embolism. While treatment of low- and high-risk PE is relatively straightforward (anticoagulation alone and anticoagulation with or without lysis, respectively), there is growing evidence to support a specific strategy to treat patients with intermediate-risk PE. Overall, treatment of intermediate PE is complex and requires a multidisciplinary team of specialist areas, including pulmonary, cardiology, cardiothoracic surgery, and interventions.

Polycythemia (elevated red blood cell count) is a rare blood disease in which the body produces too many red blood cells. Causes of polycythemia are either primary (acquired or genetic mutations) or secondary (diseases, conditions, high altitude). Examples of primary polycythemia include:

  • Fatigue
  • Excessive sweating
  • Unintended weight loss
  • Gouty arthritis, usually in big toe
  • Shortness of breath
  • Headaches
  • Dizziness
  • Weakness
  • Feeling pressure or fullness on the left side of the abdomen where the spleen is located.
  • Vision problems
  • Heavy bleeding from minor cuts
  • Bleeding from the gums
  • Itching
  • Redness in the face
  • A burning feeling in the hands and feet

Complications of a high red blood cell count include blood clots, heart attack, stroke, enlarged liver and spleen, angina (heart pain), AML leukemia, and heart failure. Blood clots in the liver or kidney can cause sudden, intense pain. Treatment goals for patients with polycythemia are to manage symptoms and reduce the risk of complications like heart attack and stroke.
