Abstract

The most commonly used areas in the lower extremity in subcutaneous injection applications are anterior and lateral surface of the thigh. The calf region, which is an alternative to these areas, is located in the lateral region of the gastrocnemius muscle. The aim of the study is to retrospectively evaluate of suitability of thigh and calf site subcutaneous adipose tissue thickness for subcutaneous injection through computed tomography sections. The sample of this descriptive study consisted of 140 adult patients over the age of 18 who underwent Contrast-Enhanced Lower Extremite Computed Tomography Angiography between March 2020 and March 2021. Subcutaneous tissue thicknesses of the anterior thigh, lateral thigh, and calf injection site of the subjects were measured by a specialist radiologist using computed tomography sections. As a result of the study, a comparison of subcutaneous tissue thickness in the thigh and calf was achieved according to gender and body mass index. The mean subcutaneous tissue thickness of the patients was 13.64 ± 6.85 mm on the anterior thigh, 8.82 ± 7.21 mm on the lateral side of the thigh, and 6.15 ± 3.12 mm in the calf area. It was found that there was a significant difference between subcutaneous tissue thicknesses according to their gender and body mass index. Subcutaneous tissue thickness on the anterior thigh was thicker than the lateral thigh and the calf injection site. Subcutaneous tissue thickness in females was greater than in males. Subcutaneous tissue thickness in the calf region was thicker than 4 mm in 77.1%, 8 mm in 19.3% and 12 mm in 12.3%.

Uyluk ve Baldır Bölgesindeki Deri Altı Yağ Dokusunun Subkutan Enjeksiyona Uygunluğunun Bilgisayarlı Tomografi ile Değerlendirilmesi

Abstract

Subkutan enjeksiyon uygulamalarında alt extremitede en fazla kullanılan bölgeler uyluk ön ve yan yüzüdür. Literatürde geçen ve pratikte kullanılan bu bölgelere alternatif olan baldır bölgesi gastroknemius kasının yan bölgesinde yer almaktadır. Araştırmanın amacı, bireylerde uyluk ve baldır bölgesi deri altı yağ dokusu kalınlığının subkutan enjeksiyona uygunluğunun bilgisayarlı tomografi kesitleri üzerinden ölçülerek retrospektif değerlendirilmesidir. Tanımlayıcı tipte olan araştırmanın örneklemini Mart 2020 – Mart 2021 tarihleri arasında Kontrastlı Alt Extremite Bilgisayarlı Tomografi Anjiografi çekilen 18 yaş üzeri 140 yetişkin birey oluşturdu. Bireylerin uyluk ön yüz, uyluk yan yüz ve baldır bölgesindeki subkutan doku kalınlıkları bir uzman radyolog tarafından bilgisayarlı tomografi kesitleri üzerinden ölçüldü. Araştırma sonucunda cinsiyet ve beden kitle indeksine göre uyluk ve baldır bölgesindeki subkutan doku kalınlığının karşılaştırılması sağlandı.
Bireylerin subkutan doku kalınlığı ortalamaları uyluk ön yüzde 13,64±6,85 uyluk yan yüzde 8,82±7,21 ve baldır bölgesinde 6,15±3,12 mm olarak bulundu. Bireylerin cinsiyet ve beden kitle indeksine göre subkutan doku kalınlıkları arasında anlamlı fark olduğu saptandı. Uyluğun ön yüzündeki subkutan doku kalınlığı uyluğun yan yüzü ve baldır bölgesine göre daha kalındı. Kadın bireylerde tüm enjeksiyon bölgesindeki subkutan doku kalınlığı erkeklerden daha fazlaydı. Baldır bölgesinde subkutan doku kalınlıkları bireylerin %77,1’inde 4 mm’den, %19,3’ünde 8 mm’den ve %12,3’ünde 12 mm’den daha kalındı.
