Echobegeleide verwijdering van plantaardige vreemde voorwerpen ter hoogte van de distale extremiteiten bij honden: een retrospectieve studie van 19 casussen

Abstract

Subcutaneous abscesses or granulomas in the lower extremities of dogs commonly occur secondary to the penetration and migration of vegetal foreign bodies (FBs). The aim of this study was to describe the clinical presentation and ultrasonographic appearance of intact grass awn FBs in the lower extremities of dogs, and their ultrasound-guided retrieval with particular emphasis on the feasibility, effectiveness and prognosis associated with this technique. In this retrospective study, 22 FBs were identified ultrasonographically in 19 dogs. The procedure resulted in the successful retrieval of the FB in 100% of dogs, and the clinical signs resolved in 90% (n=17) in less than ten days. No complications or recurrence were encountered. This study shows that ultrasonographic examination should be the first-choice modality when a vegetal FB is suspected within the distal extremity, as it allows both identification and removal of the FB with a minimally invasive procedure, with short- and long-term effectiveness and good prognosis.

Arthroscopic Removal of an Intra-Articular Migrating Plant Awn Associated with Septic Shoulder Joint Arthritis in a Dog

“…Plant (grass) awns have been encountered in different locations of the body including the ear canals, 1,2 respiratory tract and pleural space, [1][2][3][4][5] sublumbar musculature and retroperitoneal cavity, 1,2,[6][7][8] reproductive system, 9 oropharynx, 10 pericardium, 11,12 central nervous system, 13 bladder, 14 epidural space, 15 interdigital webs and lower extremities. 2,16 To the authors' knowledge, intra-articular migration of grass seeds has not yet been reported in the veterinary literature.…”

Ultrasonographic findings may be useful for differentiating interdigital abscesses secondary to migrating grass awns and interdigital furunculosis in dogs

“…Grass awn migration is frequently reported in North America 1 and Europe, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] with long-haired dogs being overrepresented. [2][3][4] Grass awns are reported to have the ability to penetrate and migrate through soft tissues, often silently for days to months before clinical signs appear.…”

“…2 The anatomic location of the grass awn at the moment of diagnosis is highly variable. 3,[5][6][7][8][9][10][11][12][13][14][15][16][17] Secondary to the migration, abscesses and draining tracts can develop and are sustained by the presence of the foreign body. After medical treatment, local inflammation is reported to recur if the foreign body has not been removed.…”

“…2,9 Therefore, identification and removal of the foreign body is necessary and is well-described in dogs. 3,16,18 Grass awns often appear on ultrasound as a multilinear spindle-shaped hyperechoic element, measuring 0.5-3.6 cm in length, 5,11,19 and associated with a peripheral hypoechoic fluid-filled cavity. [3][4][5]7,[12][13][14][15]20,21 The presence of distal acoustic shadowing is variably reported.…”

“…[3][4][5]7,[12][13][14][15]20,21 The presence of distal acoustic shadowing is variably reported. 3,4,9,11 Interdigital furunculosis is a well-described, common, and multifactorial skin disease in dogs. [22][23][24] This affection is often initiated by an underlying disease such as atopic dermatitis, and develops due to osteoarticular pain and altered weight-bearing.…”
