Romatoid artritli hastalarda elde oluşan nörovasküler komplikasyonların B mod ve renkli doppler ultrasonografi ile değerlendirilmesi

Abstract

Amaç: Romatoid artrite (RA) bağlı olarak el bileğinde oluşan kas iskelet sistemi hastalıklarını ultrasonografi ile tespit etmek ve RA'lı hastalarda arteryel dopplerdeki kan akım patern değişikliklerini saptamak amaçlanmıştır. Materyal ve metod: Amerikan Romatizma Birliği (ACR) kriterlerine göre RAtanısı koyulmuş 35 hasta (70 el bileği) ve kontrol grubu olarak 20 sağlıklı gönüllü (40 el bileği) çalışmaya alındı. Median sinir kesit alanı (MSA), anteroposterior (AP) ve transvers çaplar, karpal tünel girişi [proksimal (p)] ve bilek kıvrımı [distal (d)] düzeylerinde ölçüldü. Karpal tünel girişi düzeyinde fleksör retinakulum kalınlığı değerlendirildi. Renkli Doppler ultrason incelemesinde her iki el nötral pozisyonda iken radial ve ulnar arterler yüksek rezolüsyonlu 12 MHz transduser (Logic 7) ile değerlendirildi. Bulgular: Gruplar arası karşılaştırmada RA grubunda, kontrol grubuna göre AP-p ve AP-d çaplar anlamlı olarak daha küçük bulundu (p<0,05). RAgrubunda radial arter akım hızı ve pik sistolik hızda anlamlı azalma bulundu (p<0,05). Diğer B mod ve doppler ultrasonografi ölçümlerinde gruplar arası anlamlı fark yoktu (p>0,05). Sonuç: KTS klinik bulgu ve semptomu olmayan orta hastalık aktivitesine sahip RA'lı hastalarda sağlıklı kontrollere göre MSA sonuçları benzerdir. Kronik inflamasyona bağlı olarak median sinirin vazomotor fonksiyonlarındaki bozukluk radial kan akımındaki azalmayı açıklayabilir.

Abstract

Objective: The aim of the study is to detect the musculoskeletal diseases of the wrist depending on rheumatoid arthritis (RA) by ultrasound and to determine changes in arterial Doppler blood flow patterns in patients with RA. Materials and Methods: 35 patients (70 wrists) with a diagnosis of RA according to the American College of Rheumatology criteria and a control group of 20 healthy volunteers (40 wrists) were enrolled in the study. The median nerve cross-sectional area (MSA), anteroposterior (AP), and transverse diameters at the levels of carpal tunnel entrance [proximal (p)] and wrist bend [distal (d)] were measured. The flexor retinaculum thickness was evaluated at the level of carpal tunnel entrance. In the color Doppler ultrasound examination, radial and ulnar arteries were evaluated with high resolution 12 MHz transducer (Logic 7) while both hands were in a neutral position. Results: In comparison between the groups, AP-p and AP-d diameters were significantly smaller in the RA group than in the control group (p<0.05). The radial artery flow velocity and peak systolic velocity were significantly decreased in the RAgroup (p<0.05). There was no significant difference between the groups in other B-mode and Doppler ultrasonography measurements (p>0.05). Conclusion: RA patients with moderate disease activity and without clinical signs and symptoms of CTS have similar MSA results compared to healthy controls. The vasomotor function disorder depending on the chronic inflammation in median nerve may explain the reduction of radial blood flow.
