Accurate Noninvasive Arterial Assessment of the Wounded Lower Limb: A Clinical Challenge for Wound Practitioners

Abstract

Arterial investigations are an essential part of lower extremity wound assessment. The results of these investigations assist the wound clinician to determine the etiology of the wound, predict healing capacity, and inform further management. There are a number of noninvasive testing methods available to practitioners, all with varying levels of reliability and accuracy. Clinical wound assessment guidelines give varied recommendations when it comes to lower limb vascular assessment in the presence of a wound. This leaves clinicians with little guidance on how to choose the most appropriate test, and uncertainty remains about which tests provide the most accurate information in different patient-specific contexts. Conditions such as advanced age, diabetes, and renal disease are known to affect the accuracy of some commonly used lower limb arterial assessment methods, and alternate testing methods should be considered in these cases. This seminal review discusses the reliability and accuracy of lower limb vascular assessment methods used to guide lower limb arterial assessment in the presence of wounds.

“…At present, the examination of lower limb arterial obstructive disease mainly diagnoses the cause, location, scope and degree of the disease when the disease occurs in the main artery or larger branch. Imaging examination is an important basis and prerequisite for identifying lesions and making treatment plans ( 3 , 4 ). Although digital subtraction angiography is the gold standard of blood vessel examination, it has not been widely accepted as a routine blood vessel examination because of its invasiveness, high cost, and many complications.…”

Anterior Tibial to Dorsalis Pedis Bypass to Manage Acute Ischemia Attributed to Pilon Fracture

“…3 Therefore, complicated pilon fractures comprise a surgical challenge necessitating immediate and well-conducted collaboration by orthopedics and vascular surgeons as well as prompt diagnosis of ischemia by the treating physicians on site. 4 Moreover, this type of distal arterial reconstruction is technically demanding since it comprises distal low-caliber vessels (ie, mid anterior tibial to dorsalis pedis artery) and a vein graft crossing a swollen area of damaged tissues.…”
