Indocyanine Green (ICG) for the assessment of splenic perfusion during laparoscopic splenic artery aneurysmectomy. A case report

Abstract

 

CASE REPORT: We describe the case of a 54-year-old man with a 20mm splenic aneurysm, who underwent laparoscopic aneurysmectomy, without splenic removal. The residual splenic blood supply was assessed by using indocyanine green i.v. administration.

CLINICAL FINDINGS: The patient presented at ED with abdominal pain, syncopal episode, and tachycardia. A CT scan with contrast showed hemoperitoneum with a 20mm splenic aneurysm, which was located at the bifurcation of the splenic and left gastroepiploic artery.

Treatment and Outcome Laparoscopic surgery was then warranted. Abdominal exploration revealed a serohemorrhagic collection without active source of bleeding. After opening the gastro-colic ligament and obtaining vascular control of the splenic artery, the aneurysm was clipped and resected. No macroscopic modifications occurred to the spleen. This finding was confirmed by intravenous administration of indocyanine green. The operating time was 265 minutes. During the postoperative course, a grade A pancreatic fistula occurred. The patient was discharged on postoperative day seven.

CLINICAL RELEVANCE: The management of true splenic artery aneurysms should be patient-tailored, considering the location of the aneurysm, operative risks and the patient's age, life expectancy and clinical status. The use of ICG in splenic surgery helps delineate the splenic parenchyma and evaluate residual splenic vascularization.
