Parentral Nutrition: Centeral and Peripheral Parental Nutrition

101
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Area of Science:

  • Radiology
  • Head and Neck Surgery
  • Medical Imaging

Background:

  • Deep neck biopsies are crucial for diagnosing various conditions.
  • Ultrasound guidance has limitations in reaching certain deep neck regions.
  • Open surgical biopsies can be invasive and carry higher risks.

Purpose of the Study:

  • To review the techniques and patient preparation for computed tomography (CT) guided deep neck biopsies.
  • To illustrate favored access routes for CT-guided biopsies in both suprahyoid and infrahyoid neck regions.
  • To emphasize the importance of anatomical knowledge and imaging assessment for procedural safety.

Main Methods:

  • Review of existing literature and case studies on CT-guided neck biopsies.
  • Description of patient preparation protocols.
  • Detailed explanation of various surgical access routes, including suprahyoid (subzygomatic, retromandibular, transfacial, submastoid, transoral, posterior) and infrahyoid (anterolateral, posterolateral) approaches.

Main Results:

  • CT guidance allows biopsies of deep neck lesions previously inaccessible to ultrasound.
  • Specific access routes are detailed for suprahyoid and infrahyoid regions.
  • Proper technique and anatomical understanding are key to a low complication rate.

Conclusions:

  • CT-guided deep neck biopsies are a safe and effective alternative to open surgery.
  • A comprehensive understanding of neck anatomy and imaging is essential for successful procedures.
  • Adherence to proper techniques significantly reduces the risk of complications.
