Duplex Scanning or Arteriography for Preoperative Planning of Lower Limb Revascularisation

Abstract

the reliability of duplex scanning is comparable to digital angiography in the preoperative planning of lower extremity arterial reconstruction. However neither exam can be considered as the gold standard because intraoperative arteriography needs to be available in a significant number of infrapopliteal procedures.

New simple image overlay system using a tablet PC for pinpoint identification of the appropriate site for anastomosis in peripheral arterial reconstruction

“…The advantages of US include that it is noninvasive, it does not involve radiation exposure, and it provides hemodynamic information as well as morphological data [9][10][11]. On the other hand, its utility is limited because it requires more time than other imaging modalities and its quality is operator-dependent [6][7][8][9]12]. Eiberg et al [11] reported that the minimum training requirement for examining the infra-genicular arteries was at least 100 procedures.…”

“…The incision site for distal anastomosis in crural or pedal bypass surgery is often established preoperatively using color-assisted duplex ultrasonography (US) with reference to the results of these imaging examinations [3][4][5][6][7][8][9][10][11]. However, precise identification of the arterial portion for distal anastomosis using US is sometimes difficult, because of severe arterial calcification or the depth of the target vessel [10], and its accuracy is dependent on the skills of the operator [6][7][8]12].…”

Preoperative visualization of peripheral arteries with duplex ultrasonography in patients with diabetes mellitus and critical limb ischemia

“…Кроме того, недостатком метода РКАГ являются технические ограничения, связанные с невозможностью оценить состояние сосудистой стенки и функциональные параметры кровотока, а также неудовлетворительное контрастирование артерий дистальнее уровня окклюзии из-за низкой скорости кровотока [5,6]. В настоящее время тактика интервенционного вмешательства у пациентов с СД и КИНК все чаще определяется данными ультразвукового дуплексного сканирования (УЗДС) [7][8][9][10][11][12][13][14][15][16][17]. УЗДС в сравнении с другими методами визуализации имеет ряд преимуществ у больных СД с сопутствующими тяжелыми микро-и макрососудистыми осложнениями: неинвазивность, отсутствие токсического влияния рентгеноконтрастного препарата и возможность многократного повторения исследования [17,18].…”

Estudo comparativo de eco-Doppler com arteriografia na avaliação da doença oclusiva aorto-ilíaca

“…A outra é que a eco-Doppler permite selecionar os pacientes com lesões mais graves, mas bem localizadas, que são candidatos a terapia intervencionista por cateter [39][40][41][42][43][44][45][46][47][48][49][50][51][52] . Tradicionalmente, os candidatos a essa forma de terapia têm que ser submetidos a dois exames arteriográficos: um exame diagnóstico e um segundo exame, durante o qual é executada a intervenção.…”

“…Essa conclusão está de acordo com quase todos os trabalhos da literatura 8,[25][26][27][28][29][30][31][32][33][34][35][36][37][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54] . A eco-Doppler pode ser usada na investigação primária da DOAI, evitando-se a angiografia pré-intervenção por qualquer método (arteriografia com cateter, tomografia computadorizada e ressonância magnética) na imensa maioria dos pacientes com suspeita de DOAI.…”
