ABSTRAK Latar Belakang : pengukuran VPW dari modalitas foto toraks merupakan
pemeriksaan yang non invasif, cepat dan mudah untuk memprediksi kondisi
hipervolemia. Namun belum terdapat konsensus nilai rerata VPW yang dipakai
secara global, sehingga penggunaan nilai rerata VPW dari penelitian sebelumnya
terhadap populasi diluar populasi penelitian tersebut mungkin tidak relavan. Di
Indonesia khususnya di Rumah Sakit Cipto Mangunkusumo belum terdapat data
dasar nilai rerata VPW.
Tujuan Penelitian: Mengetahui rerata nilai VPW dewasa normal Indonesia
Desain Penelitian: Retrospektif potong lintang
Metode: Pengukuran jarak antara tepi terluar arteri subklavia kiri dengan tepi
terluar vena kava superior yang melewati bronkus utama kanan (VPW),
pengukuran rasio VPW terhadap diameter jantung terluas dan rasio VPW terhadap
diameter terluas rongga toraks. Pengukuran dilakukan pada radiografi toraks PA
dari 104 subyek normal yang terdiri dari 52 laki-laki dan 52 perempuan, dihitung
rerata dan standar deviasi. Pengukuran serupa juga dilakukan pada topogram CT
scan toraks (radiografi toraks AP supine) dan CT scan toraks dari 103 subyek
yang terdiri dari 51 laki-laki dan 52 perempuan.
Hasil: Pada pemeriksaan toraks PA didapatkan rerata VPW 48,0 mm ± 5,5 mm,
rerata VPCR 40,3% ± 4,6 %, dan rerata VPTR 17,2% ± 1,7%. Pada pemeriksaan
topogram CT scan didapatkan rerata VPW 50,3 mm ± 6,2 mm, rerata VPTR 45%
± 5,1%, dan rerata VPTR 19,8% ± 2,5%. Rerata VPW pada CT scan toraks 50,4 ±
6,1 mm. Pengukuran pada foto toraks AP sekitar 10 % lebih besar dibandingkan
pada foto toraks PA, dan pengukuranVPW pada foto toraks terbukti memiliki
akurasi yang tinggi.
Kesimpulan: Rerata VPW pada pemeriksaan foto toraks PA tegak dewasa normal
Indonesia adalah 48 ± 5,5 mm, ternyata tidak berbeda bermakna dengan rerata
VPW pada populasi barat ( 48 ± 5mm). Rerata VPCR pada foto toraks PA
adalah 40,3 % ± 4,6 % dan VPTR adalah 17,2 % ± 1,7 %.
ABSTRACTBackground: Vascular pedicle width (VPW) is the distance, from a perpendicular
line at the takeoff point of the left subclavian artery off the aorta to the point at
which the superior vena cava. Measurement of VPW on chest x-ray is relatively
non-invasive, fast and easy technique as hypervolemia predictor, but no
wordwide consensus has been proposed.
Objective: to investigate mean vascular pedicle witdh of Indonesian adult
Study design: Retrospective cross sectional
Methods : VPW is the distance, measure in millimeters, from a perpendicular line
at the takeoff point of the left subclavian artery to the point at which the superior
vena cava crosses the right main bronchus, than calculate VPW ratio to a widest
horizontal diameter of cardiac dan thoracic wall.
Results : Data from 104 PA chest x-ray of normal subjects and 103 thoracic CT
scan of selected subjects. On PA chest x-ray obtained mean VPW 48,0 mm ± 5.5
mm, mean VPCR 40.3% ± 4.6%, and mean VPTR 17.2% ± 1.7%. On CT scan
topogram obtained mean VPW 50,3 mm ± 6.2 mm, mean VPTR 45% ± 5.1%, and
mean VPTR 19.8% ± 2.5%. On thoracic CT scan obtained mean VPW 50.4 ± 6.1
mm. Measurements on the AP chest x-ray about 10% greater than in the PA
chest x-ray, and measurement of VPW on conventional chest x-ray aproved to
have high accuracy.
Conclusions :The mean VPW on erect chest x-ray of Indonesian adult is 48 ± 5,5
mm, no significant different between westerns population ( 48 ± 5mm).;Background: Vascular pedicle width (VPW) is the distance, from a perpendicular
