  • Pulmonary Embolism (Pe): Diagnosis
    PULMONARY EMBOLISM (PE): DIAGNOSIS OBJECTIVE: To provide a diagnostic approach to patients with suspected acute pulmonary embolism (PE). BACKGROUND: Venous thromboembolism (VTE), which comprises deep vein thrombosis (DVT) and pulmonary embolism (PE), is a common disease, affecting approximately 1-2 in 1,000 adults per year. The diagnosis of PE has increased significantly since the advent of computed tomography pulmonary angiography (CTPA) with its widespread availability and enhanced sensitivity. The majority of PE originates in the proximal deep veins of the leg, despite the observation that only 25-50% of patients with PE have clinically evident DVT at the time of PE diagnosis. While active malignancy, surgery (especially orthopedic), hospitalization, air travel >8 hours, and hormone use/pregnancy are common transient provoking factors, approximately 50% of first-time PEs appear to be unprovoked. Symptoms of PE may include sudden onset dyspnea, pleuritic chest pain, and syncope. Signs of PE may include tachypnea, tachycardia, hypoxemia, hypotension, and features of right ventricular dysfunction (distended jugular veins). There may be accompanying signs and symptoms of DVT. The ECG may show right ventricular strain (S1Q3T3, right bundle branch block and T-inversion in leads V1- V4). Up to 10% of symptomatic PEs are fatal within the first hour of symptom onset. Independent predictors of mortality within the first few days after diagnosis of PE include hypotension (systolic blood pressure [SBP] <90 mmHg), clinical right heart failure, right ventricular dilatation on CTPA/echocardiography, positive troponin, and elevated brain natriuretic peptide (BNP). Early diagnosis and treatment of PE reduces morbidity and mortality. DIAGNOSIS OF PE: The constellation of symptoms and signs may be suggestive of PE but do not alone have the sensitivity or specificity to rule in or rule out the diagnosis.

  • Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE)
    How can it be prevented? You can take steps to prevent deep vein thrombosis (DVT) and pulmonary embolism (PE). If you're at risk for these conditions: • See your doctor for regular checkups. • Take all medicines as your doctor prescribes. • Get out of bed and move around as soon as possible after surgery or illness (as your doctor recommends).

Abstract Hemothorax is defined as a bleeding into pleural cavity. Hemothorax is a frequent manifestation of blunt chest trauma. Some authors suggested a hematocrit value more than 50% for differentiation of a hemothorax from a sanguineous pleural effusion. Hemothorax is also often associated with penetrating chest injury or chest wall blunt chest wall trauma with skeletal injury. Much less common, it may be related to pleural diseases, induced iatrogenic or develop spontaneously. In the vast majority of blunt and penetrating trauma cases, hemothoraces can be managed by relatively simple means in the course of care. Keywords: Traumatic hemothorax; Internal chest wall; Cardiac Hemodynamic response injury; Clinical manifestation; Blunt chest-wall injuries; Blunt As above mentioned the hemodynamic response is a multifactorial intrathoracic injuries; Penetrating thoracic trauma response and depends on severity of hemothorax according to its classification.

Spontaneous hemothorax is uncommon and among its cause may include coagulation disorders, pleural, pulmonary or vascular pathology. Diagnostics is based on radiography or ultrasound and thoracentesis which may be also therapeutic solution. The majority of hemothoraxes can be managed non-operatively but hemodynamic instability, the volume of evacuated blood and persisting blood loss or persisting hemothorax require surgery. A surgical approach may vary from open thoracotomy to rapidly developing minimally invasive methods - video-assisted thoracoscopic surgery (VATS) and videothoracoscopy (VTS). Key words: hemothorax; surgery; VATS; thoracotomy Introduction Hemothorax is a pathological collection of the blood within the pleural cavity. Hemothorax most frequently origin in a thoracic injury but the exact incidence is not known.
