Chak-Lam Cho, Kwan-Lun Ho, Wayne Kwun-Wai Chan, Ringo Wing-Hong Chu, In-Chak Law
Microsurgical subinguinal varicocelectomy (MSV) is generally considered the gold standard nowadays in view of the lower risk of complications and recurrence. To achieve complete ligation of veins while preserving testicular artery (TA) during the procedure remains challenging despite the application of high power optical magnification and micro-Doppler ultrasonography. The use of intraoperative indocyanine green angiography (ICGA) with infrared fluorescence operative micro-scope in MSV potentially lowers the incidence of TA injury and shortens the learning curve of nov-ice surgeons...

INTRODUCTION: The newly developed optical coherence tomography angiography (OCT-A) has provided new means to depict the vascular plexus in neovascular age-related macular degeneration (nAMD). If these images are to be used as a basis for therapeutic decisions, it is of vital importance to classify choroidal neovascularization (CNV) as either classical or occult. This study aimed at comparing the findings in OCT-A imaging of CNV with the traditional multimodal imaging through fluorescein angiography (FLA) and indocyanine green angiography (ICGA)...

BACKGROUND: In immediate tissue expander reconstruction following total mastectomy for breast cancer, indocyanine green angiography (ICGA)-guided skin trimming is useful for the prevention of complications. However, instances of unclear ICGA contrast can occur with this method, which are difficult to judge as to whether preventive trimming is warranted. To further improve the mastectomy flap necrosis rate, more accurate objective parameters are necessary. METHODS: The degree of clinical improvement was compared between 81 patients trimmed according to the surgeon's judgment (non-ICGA group) and 100 patients with ICGA-guided trimming (ICGA group)...

Choroidal neovascularisation (CNV) in the context of exsudative age-related macular degeneration (nAMD) can be divided into type 1 (occult) and type 2 (classical) membranes. Retinal angiomatous proliferation (RAP) or polypoidal choroidal vasculopathy (PCV) are "rare subtypes" of chorioretinal neovascularisation and are distinguished by their distinct morphology and the sometimes worse response to therapy. Chorioretinal anastomosis, severe exsudates with serosanguinous pigment epithelial detachment and, in PCV, orange-red lesions in the papillomacular bundle can be diagnostic...
