Peripheral Vascular Repair

SOC → SCF-DBI Logic Translation

Purpose

Peripheral Vascular Repair is the surgical restoration of arterial and/or venous continuity within the extremities following traumatic, iatrogenic, ischemic, or reconstructive vascular injury.

The procedure is performed to preserve limb viability, restore perfusion, prevent tissue necrosis, maintain neuromuscular function, and avoid limb loss.

SOC Definition

Clinical Objective

Restore vascular integrity by:

• Repairing injured arteries
• Repairing injured veins
• Restoring distal blood flow
• Re-establishing venous drainage
• Preserving limb viability
• Preventing ischemic injury

Common Techniques

Primary Repair

• End-to-end anastomosis
• Lateral repair
• Patch angioplasty

Interposition Grafting

• Autologous vein graft
• Prosthetic graft
• Biological conduit

Hybrid Repair

• Open repair plus endovascular intervention
• Temporary shunting followed by definitive reconstruction

Common Indications

Traumatic Vascular Injury

• Penetrating trauma
• Blunt vascular disruption
• Open fractures with vascular injury

Acute Limb Ischemia

• Arterial thrombosis
• Embolic occlusion

Reconstructive Surgery

• Limb salvage
• Complex extremity reconstruction

SCF-DBI Translation

Core Concept

SOC views Peripheral Vascular Repair as:

Restoration of vessel continuity.

SCF-DBI views Peripheral Vascular Repair as:

Restoration of the Limb Perfusion Intelligence Network (LPIN).

The objective extends beyond blood flow restoration.

The objective is preservation and recovery of:

1. Limb perfusion
2. Microvascular integrity
3. Neuromuscular viability
4. Endothelial stability
5. Regenerative capacity
6. Functional limb resilience

SCF Classification

Limb Perfusion Failure Syndrome (LPFS)

A progressive regional collapse state caused by interruption of arterial inflow and/or venous outflow.

Output

Limb DBI Perfusion-Restoration Score (LPRS)

(Primary SCF-DBI Enhancement)

This becomes the principal SCF-DBI enhancement beyond conventional vascular repair.

Domain 2

Limb DBI Perfusion-Restoration Score

Major SCF-DBI Enhancement

Traditional vascular repair success is measured by:

• Pulse restoration
• Doppler signals
• Vessel patency

LPRS States

Output

Limb DBI Perfusion-Restoration Score (LPRS)

Domain 3

Neuromuscular Viability Intelligence

SCF-DBI Enhancement

Limb survival depends upon preservation of:

• Nerves
• Muscle
• Motor function

not simply vascular patency.

Assessment Domains

Output

Neuromuscular Viability Score (NMVS)

Domain 4

Endothelial Recovery Surveillance

SCF-DBI Enhancement

Peripheral ischemia frequently produces:

• Glycocalyx injury
• Endothelial dysfunction
• Microvascular collapse

even after successful repair.

Assessment Domains

Output

Peripheral Endothelial Recovery Score (PERS-PV)

Domain 5

Reperfusion Injury Risk Modeling

SCF-DBI Enhancement

Restoration of blood flow may trigger:

• Oxidative stress
• Inflammatory activation
• Compartment syndrome
• Rhabdomyolysis
• Organ dysfunction

Assessment Domains

Risk Categories

Output

Domain 6

Limb Salvage Readiness Assessment

SCF-DBI Enhancement

Repair success is ultimately judged by salvage potential.
