**Question:** The percutaneous PAIR therapy used in the treatment of uncomplicated hepatic hydatid cyst can be associated with the following complications, Except:

A. Hemorrhage
B. Respiratory compromise
C. Liver abscess
D. Renal failure

**Core Concept:**
Hydatid disease is caused by the larval stage of the dog tapeworm Echinococcus granulosus. In humans, it commonly affects the liver and lungs. Percutaneous PAIR (Puncture, Aspiration, Injection, Reaspiration) is a minimally invasive procedure used to treat uncomplicated hepatic hydatid cysts.

**Why the Correct Answer is Right:**
D. Renal failure is not typically associated with percutaneous PAIR therapy for hepatic hydatid cysts because renal function is not directly affected by the procedure. The procedure primarily targets the liver and does not involve renal structures.

**Why Each Wrong Option is Incorrect:**
A. Hemorrhage (Option A): Percutaneous PAIR therapy can lead to minor bleeding into the cyst due to the puncture and injection steps. However, severe hemorrhage requiring intervention is unusual.

B. Respiratory compromise (Option B): This is unlikely as the procedure does not involve significant manipulation of respiratory structures.

C. Liver abscess formation (Option C): Although the procedure may introduce bacteria from the skin into the cyst, complications related to liver abscess formation are rare.

**Clinical Pearl:**
While percutaneous PAIR therapy is a safe and effective method for treating uncomplicated hepatic hydatid cysts, patients should be closely monitored post-procedure for potential complications like hemorrhage and liver abscess. In rare cases, respiratory compromise and renal failure can occur, making it essential to be aware of these possibilities during patient care. Careful planning, execution, and post-procedural management can minimize these risks.
