Post operative Pulmonary Thromboembolism is seen in all, except :
**Core Concept**
Postoperative pulmonary thromboembolism (PTE) is a serious complication that can occur after surgery, often due to **venous thromboembolism (VTE)**. The underlying principle being tested is the identification of risk factors and conditions that predispose to or are associated with PTE. This involves understanding **coagulation pathways** and **surgical risk factors**.
**Why the Correct Answer is Right**
Since the correct answer is not provided, let's focus on the general concept. PTE is more likely to occur in conditions that increase **coagulability of blood**, **immobility**, or **endothelial damage**. Surgical procedures, especially those involving the abdomen, pelvis, or lower extremities, increase the risk of VTE due to prolonged immobilization and activation of the **coagulation cascade**.
**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details, we cannot directly address why each option is incorrect. Normally, we would discuss how each option either increases or does not significantly impact the risk of postoperative PTE, focusing on the pathophysiology or clinical evidence related to **surgery**, **trauma**, **cancer**, or other conditions.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **early mobilization** and **prophylactic anticoagulation** are crucial in preventing postoperative PTE in high-risk patients. Understanding the **Virchow's triad** (hypercoagulability, blood flow changes, and endothelial injury) helps in identifying patients at risk.
**Correct Answer:** Correct Answer: D. Minor surgery under local anesthesia.
