Vasküler Travmaların Epidemiyolojisi
Özet
Travmatik damar hastalıkları her yaştaki hastada karşımıza çıkabilecek hayatı tehdit eden durumlardan biridir. Travmanın şekli, yaralanma bölgesi, hayati organlara ve büyük vasküler yapılara yakınlığı, travma sonrasında hastaneye ulaşıncaya kadar geçen süre gibi faktörler bu hastaların klinik seyirlerini öngörmede önemli unsurlardır. Vasküler travma düşündüğümüz bir hastada yapılacak hızlı bir fizik muayeneden sonra tanıyı kesinleştirmek ve yapılacak girişimlerin şeklini belirlemek için görüntüleme yöntemlerini kullanmak günümüzde hasta değerlendirmenin vazgeçilmez bir parçasıdır. Tecrübeli bir radyoloji uzmanı tarafından yapılan Doppler USG ekstremite vasküler yaralanmaları hakkında önemli bilgiler verebilmektedir. Ancak tanıyı kesinleştirecek ve girişim stratejilerimizi belirleyecek en önemli tetkik BT anjiografi görüntülemesidir. Gelişen teknoloji ile birlikte çok kesitli BT anjiografiler vasküler yapı hakkında detaylı bilgi sunmakta ve damar yaralanmasının ekartasyonu veya tanı koydurması açısından neredeyse zorunlu hale gelmiştir. Vasküler yaralanma tanısı için yapılan arteriografi ve venografi gibi invaziv tetkikler günümüzde çok nadiren gerekmektedir. Görüntülemeler sırasında non-invaziv tetkiklerin kullanılması ile hem hastalar invaziv tetkiklerin getirebileceği komplikasyonların riskinden korunmakta hem de travmanın şüpheli olduğu durumlarda hastaya ek girişim yapılmadan hızlıca tanı konulabilmektedir.
Bu bölümde penetran ve künt travmalarla meydana gelebilecek çeşitli damar yaralanmalarında yapılabilecek ve tercih edilebilecek görüntüntüleme yöntemlerinden bahsedilmiştir.
Traumatic vascular injuries are life-threatening conditions that can occur in patients of any age. Factors such as the mechanism of trauma, the site of injury, proximity to vital organs and major vascular structures, and the time elapsed before reaching the hospital significantly influence the clinical course of these patients. In modern medical practice, imaging techniques have become an indispensable component of patient evaluation following a rapid physical examination in cases where vascular trauma is suspected, to confirm the diagnosis and determine the course of intervention.
Doppler ultrasonography (USG) performed by an experienced radiologist can provide valuable information regarding extremity vascular injuries. However, the most crucial diagnostic tool for confirming the diagnosis and planning intervention strategies is computed tomography (CT) angiography. Advances in technology have made multi-slice CT angiography essential, offering detailed information about vascular structures and becoming nearly indispensable for ruling out or diagnosing vascular injuries.
Invasive investigations such as arteriography and venography, once commonly employed for diagnosing vascular injuries, are now rarely required. The use of non-invasive imaging methods not only spares patients from the risks of complications associated with invasive procedures but also allows for rapid diagnosis in cases of suspected trauma without the need for additional interventions.
This section discusses imaging techniques that can be employed or preferred for evaluating various vascular injuries resulting from penetrating and blunt trauma.
