Developing an Indocyanine Green Angiography Protocol for Predicting Flap Necrosis During Breast Reconstruction.
Surg Innov
January 2025
Department of Breast Surgery, Chris O'Brien Lifehouse, Camperdown, NSW, Australia.
Background: Although there is evidence that indocyanine green angiography (ICGA) can predict mastectomy skin flap necrosis during breast reconstruction, consensus on optimal protocol is lacking. This study aimed to evaluate various technical factors which can influence ICG fluorescence intensity and thus interpretation of angiograms.
Method: Single institution retrospective study (2015-2021) of immediate implant-based breast reconstructions postmastectomy using a standardized technique of ICGA, controlling for modifiable factors of ambient lighting, camera distance and ICG dose.
Indocyanine Green Angiography for Real-time Evaluation of Nasoseptal Flap Vascularity and Perfusion.

December 2024
Division of Neurosurgery, Department of Surgery, Faculty of Medicine, Thammasat University Hospital, Thammasat University, Pathumthani, Thailand.
Objectives: To investigate the characteristics of the vascular pedicle of the nasoseptal flap (NSF) and its perfusion patterns using intraoperative indocyanine green (ICG) angiography during endoscopic skull base surgery (ESBS), and examine the correlation between ICG perfusion patterns and clinical outcomes, including postoperative cerebrospinal fluid (CSF) leak and flap necrosis.
Methods: This study enrolled patients undergoing ESBS between January 2017 and December 2021. Intraoperative ICG angiography was performed to visualize the arterial supply of the nasal septum and evaluate NSF perfusion.
Indocyanine green in left side colorectal surgery segmental resection to decrease anastomotic leak: A parallel retrospective cohort study of 115 patients.

Department of General Surgery, Piacenza General Hospital, Piacenza, Italy.
Background: We investigated the impact of Indocyanine Green (ICG) angiography on reducing anastomotic leakage (AL) after elective left segmental colon resection, including transverse resection. While ICG is widely used in colorectal surgery to assess vascularization, its true effect on AL, particularly in left segmental resections, remains unclear.
Study Design: This retrospective, monocentric cohort study included patients undergoing left and transverse colon resection from January 2017 to July 2023.

Breast reconstruction with implants is now the preferred procedure following mastectomies. For successful reconstruction, accurate evaluation of the patient and skin flap viability is essential. This study aimed to analyze the impact of risk factors on mastectomy skin flap necrosis (MSFN) and the effectiveness of indocyanine green angiography (ICGA) in preventing complications.

Article Synopsis
- This study investigated eye and small blood vessel issues in patients who experienced symptoms after recovering from COVID-19, analyzing 44 patients mostly around 47 years old.
- Using advanced imaging techniques, researchers found significant retinal abnormalities, including hyperreflective dots and areas of capillary non-perfusion, indicating compromised blood flow.
- The results suggest that these retinal changes are linked to reduced capillary density, highlighting the importance of microvascular damage instead of just lasting problems with a protective layer around blood vessels.
