​What is Surgery – Pulmonary Embolism causes

DEFINITION 
The most prevalent cause of pulmonary vessel occlusion is a thrombus that has travelled to the circulatory system from another location. 

AETIOLOGY 
Thrombus (>95 percent originating from DVT of the lower limbs, with the right atrium in patients with atrial fibrillation being the uncommon exception). Amniotic fluid, air, fat, tumours, and mycotic emboli from right-sided endocarditis are among the other factors that can embolize pulmonary vessels. Surgical patients, as well as those with immobility, obesity, OCP, heart failure, and cancer, are at danger. 

EPIDEMIOLOGY 
Relatively prevalent, especially in hospitalised patients; 10–20% of those with a proven proximal DVT develop this condition. 

HISTORY It is determined by the size and location of the pulmonary embolus. Small: It's possible that it's asymptomatic. Sudden onset dyspnoea, cough, haemoptysis, and pleuritic chest discomfort are moderate cases of emboli.  All of the above plus severe central pleuritic chest pain, shock, collapse, acute right heart failure, or sudden death for large or proximal. Symptoms of pulmonary hypertension include several minor recurring headaches.

EXAMINATION Clinical probability evaluation: Various scores can be used to forecast probability, which can help with future inquiry and management. Follow the rules in your area. The severity of a pulmonary embolism can be determined by the following signs: Small: There are frequently no clinical indications. Tachycardia or tachypnoea is the first symptom. Moderate: tachycardia, pleural rub, and low oxygen saturation (despite oxygen supplementation). Shock, cyanosis, and symptoms of right heart strain (JVP, left parasternal heave, exaggerated S2 heart sound) are all present in a massive PE. Signs of pulmonary hypertension and right heart failure in multiple recurrent PE.

INVESTIGATIONS 
Use the D-dimer blood test (cross-linked fibrin degradation products, sensitive but poor specificity) if you have a low chance. High probability: Imaging is required. Additional preliminary investigations include: ABG and thrombophilia screening should be considered. ECG: May be normal or exhibit tachycardia, right axis deviation, or RBBB, among other things. It's rare to see a classic SI, QIII, or TIII pattern. CXR: Usually normal, but used to rule out alternative possibilities. Spiral CT pulmonary angiography is the preferred first-line investigation. Small emboli have low sensitivity, but medium to large emboli have high sensitivity. Administration of IV 99mTc macro-aggregated albumin and inhalation of krypton-81 gas during a ventilation-perfusion (VQ) scan. Any locations of ventilation and perfusion mismatch are identified. Because of the difficulty in interpreting an abnormal CXR or concurrent lung disease, it is not recommended. Pulmonary angiography is the gold standard, but it is also the most invasive. It's only used on rare occasions. To check for venous thrombosis, a Doppler USS of the lower limb is used. Right heart strain may be visible on an echocardiogram. 

MANAGEMENT 
Primary prevention: For those at risk, graduated pressure stockings (TEDs) and heparin prophylaxis are recommended (e.g. undergoing surgery). Following surgery, early mobilisation and appropriate hydration are essential. If haemodynamically stable, O2, heparin or LMW heparin anticoagulation, then oral warfarin therapy (INR 2–3) for a minimum of 3 months. Analgesics are pain relievers. If you have a severe case of haemodynamic instability (massive PE), you should: If cardiac arrest is imminent, resuscitation, oxygen, IV fluid resuscitation, and thrombolysis with tPA (tissue plasminogen activator) can all be considered on clinical grounds alone. Surgical or radiological intervention: Embolectomy when thrombolysis is contraindicated. For recurrent pulmonary emboli despite appropriate anticoagulation or when anticoagulation is contraindicated, IVC filters (e.g. Greenfield filter) may be placed. 

COMPLICATIONS Death, pulmonary embolism, pulmonary hypertension, and right heart failure are all possible outcomes. 

PROGNOSIS Untreated mortality was 33%, while treated mortality was 8% (due to recurrent emboli or underlying disease). Patients are at risk of developing thrombo-embolic illness in the future.
