Indocyanine green (ICG) angiography is used for the intra-operative assessment of the graft vessel in coronary artery bypass grafting to enable immediate revision if necessary. We report the feasibility and implications of an ICG colour imaging system, HyperEye Medical System (HEMS), in surgeries for arteriosclerosis obliterans (ASO) and abdominal aortic aneurysm (AAA) which carry risk of mesenteric ischaemia.
HEMS ICG angiography was used for the intra-operative assessment of 12 ASO patients and 10 AAA patients.
In the ASO patients, HEMS angiography enabled visualisation of the graft and native artery. The fluorescent lucent region in the artery distal to the anastomosis was shown in 1 of 12 ASO patients. There was a 3-s time lag in the increase of intensity between the proximal artery and distal stenotic region. In AAA patients, HEMS angiography clearly showed the perfusion in the mesenteric arteries and intestinal wall as opaque. One AAA patient had segmental ischaemia due to thromboembolism and another one had diffuse ischaemia due to systemic malperfusion. The ischaemic region of the intestine was visualised as a fluorescent lucent area by HEMS angiography.
HEMS angiography can accurately assess peripheral arterial perfusion in surgical cases with ASO and AAA.
吲哚菁绿（ICG）血管造影术用于冠状动脉旁路移植术中移植血管的术中评估，如果需要，可以立即进行修正。我们报告了一种 ICG 彩色成像系统——HyperEye Medical System（HEMS）在治疗动脉硬化闭塞症（ASO）和腹主动脉瘤（AAA）手术中的可行性和意义，这些手术有肠系膜缺血的风险。
HEMS ICG 血管造影术用于 12 例 ASO 患者和 10 例 AAA 患者的术中评估。
在 ASO 患者中，HEMS 血管造影术能够观察到移植物和原生动脉。在 12 例 ASO 患者中的 1 例中，显示了吻合口远端动脉荧光透明区域。近端动脉和远端狭窄区域之间的强度增加存在 3 秒的时间延迟。在 AAA 患者中，HEMS 血管造影术清楚地显示了肠系膜动脉和肠壁的灌注呈不透明。1 例 AAA 患者因血栓栓塞导致节段性缺血，另 1 例因全身灌注不良导致弥漫性缺血。HEMS 血管造影术可将肠的缺血区域显示为荧光透明区域。
HEMS 血管造影术可准确评估 ASO 和 AAA 手术中外周动脉灌注情况。
