Ultrasound guided Percutaneous drainage procedure

Radiology Update – 2025: Ultrasound Guided Percutaneous Drainage Procedures
Held on November 16, 2025, “Radiology Update – 2025” was an intensive hands-on cadaveric workshop dedicated to mastering Ultrasound-Guided Percutaneous Drainage Procedures. Jointly organized by the Department of Radiology and the Department of Anatomy, this CME-accredited workshop brought together interventional radiologists and clinical anatomists to refine real-time percutaneous interventions on high-fidelity cadaveric models.

The workshop enrolled 15 clinical faculty delegates, providing dedicated sonography workstation access, high-resolution ultrasound consoles, specialized drainage hardware, and personalized 1:1 proctoring from senior interventional radiologists.

Key Workshop Highlights & Objectives
Faculty delegates practiced real-time transducer manipulation, acoustic window selection, needle-beam alignment, Seldinger wire exchange techniques, and trocar catheter deployment across thoracic, abdominal, and retroperitoneal fluid compartments.

  • Real-Time Sonographic Guidance – In-plane and out-of-plane needle tracking for precise cavity puncture
  • Percutaneous Drainage Hardware – Hands-on training in Seldinger wire exchange, tract dilation, and pigtail catheter deployment
  • Radiology & Anatomy Synergy – Cross-sectional sonographic views correlated with deep anatomical planes
  • Exclusive Faculty Cohort – Strictly limited to 15 faculty members for maximized individual machine and procedure time
  • Vascular Safety Protocols – Doppler vascular mapping to avoid intercostal, epigastric, and mesenteric vessels
All cadaveric specimens were prepared and managed in accordance with institutional ethical guidelines, delivering realistic acoustic impedance, tissue tactile resistance, and sonographic feedback essential for interventional procedures.
Structured 1-Day Intensive Cadaveric Program (16/11/2025)
The single-day program delivered an optimal balance between didactic interventional principles, live machine setup demonstrations, and comprehensive wet-lab station simulations.
The morning sessions focused on ultrasound physics, transducer selection, ergonomics of probe-needle alignment, and thoracic/pleural space access. The afternoon sessions progressed into abdominal, pelvic, and retroperitoneal collections, mastering guide-wire exchanges, fascial dilations, and secure catheter fixation.

Procedural Breakdown & Station Curriculum

Session 1: Thoracic & Pleural Access | Session 2: Abdominal & Hepatic Collections | Session 3: Deep Pelvic & Retroperitoneal
Intercostal vascular mapping & rib clearance | Liver abscess / subphrenic space simulation | Retroperitoneal space & iliopsoas drainage
Thoracocentesis & pigtail chest drain insertion | Seldinger vs. Trocar catheter placement | Catheter fixation, flushing & patency maintenance
Pleural effusion aspiration under real-time USG | Guidewire negotiation & fascial serial dilation | Managing obstructed drains & kinking

Core Interventional Modules
Delegates executed ultrasound-guided needle trajectories and catheter placements under direct guidance from senior interventional radiologists:

Optimization of ultrasound controls (gain, depth, focal zone, frequency). In-plane versus out-of-plane needle visualization, transducer grip, beam alignment, and eliminating acoustic artifacts during needle advancement.
Safe rib-crossing technique along the superior rib border to prevent damage to the intercostal neurovascular bundle. Needle thoracocentesis and insertion of locking pigtail catheters for empyema and pleural fluid drainage.
Targeting fluid collections in liver parenchyma and subdiaphragmatic spaces. Planning entry windows avoiding the pleura, colon, and major portal/hepatic vessels using color Doppler interrogation.
Needle aspiration confirmation, introducer J-tip guidewire passage under sonographic tracking, step-wise tract dilation using serial fascial dilators, and deployment of 8F to 14F locking pigtail catheters.
Navigation through deep pelvic and iliopsoas corridors with real-time avoidance of femoral and external iliac vessels. Catheter string-locking mechanics, skin anchoring, dressing, and drainage bag assembly.
Anatomy faculty reinforced sectional anatomy across thoracic and peritoneal reflections, highlighting anatomical variations and potential collateral injury pathways.
Eligibility & Technical Infrastructure
Tailored for clinical faculty members and senior practitioners aiming to enhance interventional radiology skills in emergency and elective drainage procedures.
All participants underwent safety briefings on sterile field preservation during probe manipulation, acoustic gel handling, and wire exchange protocols.
