[ABSTRAK
Latar Belakang : pengukuran VPW dari modalitas foto toraks merupakanpemeriksaan yang non invasif, cepat dan mudah untuk memprediksi kondisihipervolemia. Namun belum terdapat konsensus nilai rerata VPW yang dipakaisecara global, sehingga penggunaan nilai rerata VPW dari penelitian sebelumnyaterhadap populasi diluar populasi penelitian tersebut mungkin tidak relavan. DiIndonesia khususnya di Rumah Sakit Cipto Mangunkusumo belum terdapat datadasar nilai rerata VPW.Tujuan Penelitian: Mengetahui rerata nilai VPW dewasa normal IndonesiaDesain Penelitian: Retrospektif potong lintangMetode: Pengukuran jarak antara tepi terluar arteri subklavia kiri dengan tepiterluar vena kava superior yang melewati bronkus utama kanan (VPW),pengukuran rasio VPW terhadap diameter jantung terluas dan rasio VPW terhadapdiameter terluas rongga toraks. Pengukuran dilakukan pada radiografi toraks PAdari 104 subyek normal yang terdiri dari 52 laki-laki dan 52 perempuan, dihitungrerata dan standar deviasi. Pengukuran serupa juga dilakukan pada topogram CTscan toraks (radiografi toraks AP supine) dan CT scan toraks dari 103 subyekyang 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 pemeriksaantopogram 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 dibandingkanpada foto toraks PA, dan pengukuranVPW pada foto toraks terbukti memilikiakurasi yang tinggi.Kesimpulan: Rerata VPW pada pemeriksaan foto toraks PA tegak dewasa normalIndonesia adalah 48 ± 5,5 mm, ternyata tidak berbeda bermakna dengan rerataVPW pada populasi barat ( 48 ± 5mm). Rerata VPCR pada foto toraks PAadalah 40,3 % ± 4,6 % dan VPTR adalah 17,2 % ± 1,7 %.
ABSTRACT
Background: Vascular pedicle width (VPW) is the distance, from a perpendicularline at the takeoff point of the left subclavian artery off the aorta to the point atwhich the superior vena cava. Measurement of VPW on chest x-ray is relativelynon-invasive, fast and easy technique as hypervolemia predictor, but nowordwide consensus has been proposed.Objective: to investigate mean vascular pedicle witdh of Indonesian adultStudy design: Retrospective cross sectionalMethods : VPW is the distance, measure in millimeters, from a perpendicular lineat the takeoff point of the left subclavian artery to the point at which the superiorvena cava crosses the right main bronchus, than calculate VPW ratio to a widesthorizontal diameter of cardiac dan thoracic wall.Results : Data from 104 PA chest x-ray of normal subjects and 103 thoracic CTscan of selected subjects. On PA chest x-ray obtained mean VPW 48,0 mm ± 5.5mm, mean VPCR 40.3% ± 4.6%, and mean VPTR 17.2% ± 1.7%. On CT scantopogram obtained mean VPW 50,3 mm ± 6.2 mm, mean VPTR 45% ± 5.1%, andmean VPTR 19.8% ± 2.5%. On thoracic CT scan obtained mean VPW 50.4 ± 6.1mm. Measurements on the AP chest x-ray about 10% greater than in the PAchest x-ray, and measurement of VPW on conventional chest x-ray aproved tohave high accuracy.Conclusions :The mean VPW on erect chest x-ray of Indonesian adult is 48 ± 5,5mm, no significant different between westerns population ( 48 ± 5mm).;Background: Vascular pedicle width (VPW) is the distance, from a perpendicularline at the takeoff point of the left subclavian artery off the aorta to the point atwhich the superior vena cava.
