A 40 years old male was brought emergency with severe abdominal pain. On examination, pulse rate was 112/minute and systolic BP was 80 mmHg. Chest x-ray is given below. What is the most appropriate management?
**Core Concept**
The patient is likely suffering from a severe case of **spontaneous rupture of the abdominal aorta (Stanford type A)**, which is a medical emergency requiring immediate surgical intervention. This condition is characterized by a tear in the aorta's wall, leading to rapid blood loss and hypovolemic shock.
**Why the Correct Answer is Right**
The patient's symptoms, including severe abdominal pain, tachycardia (112/minute), and hypotension (systolic BP 80 mmHg), are consistent with a massive intra-abdominal hemorrhage. The chest x-ray may show mediastinal widening due to blood accumulation in the mediastinum. In this scenario, the most appropriate management is immediate surgical repair of the aortic rupture, which involves **endovascular aneurysm repair (EVAR)** or **open repair**. The goal is to restore blood flow to the aorta and prevent further blood loss.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not address the patient's life-threatening condition. Administering **naloxone** is appropriate for opioid overdose, but it does not treat aortic rupture.
**Option B:** This option is incorrect as it does not provide adequate treatment for the patient's condition. **Fluid resuscitation** is essential in hypovolemic shock, but it is not sufficient to address the underlying cause of the patient's symptoms.
**Option C:** This option is incorrect as it does not provide the most appropriate management for the patient's condition. **Thrombolytic therapy** may be contraindicated in aortic rupture due to the risk of further bleeding.
**Option D:** This option is incorrect as it does not provide the most appropriate management for the patient's condition. **Angiography** may be useful in diagnosing vascular injuries, but it does not treat the patient's aortic rupture.
**Clinical Pearl / High-Yield Fact**
In cases of suspected aortic rupture, it is essential to have a high index of suspicion and to promptly initiate surgical consultation. The patient's condition can deteriorate rapidly, and timely intervention is crucial to prevent mortality.
**Correct Answer:** D. Angiography may be useful in diagnosing vascular injuries, but the primary management of a suspected aortic rupture is immediate surgical repair.
