Angioscopy guided semiclosed technique for in situ bypass

Intraoperative angioscopy may improve the outcome of in situ saphenous vein bypass grafting: a prospective study.

OBJECTIVE To find out whether intraoperative angioscopic assistance has any effect on graft outcome in patients with critical leg ischemia. MATERIAL AND METHODS One hundred one patients requiring a below-knee bypass were assigned to undergo in situ saphenous vein bypass with or without intraoperative angioscopic assistance; otherwise treated similarly including preoperative duplex vein mappin...

Angioscopy-guided selective aspiration thrombectomy for acute pulmonary thromboembolism.

Komatsu S, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-220059 An 83-year-old woman with a history of pulmonary thromboembolism 10 years ago was referred for dyspnea. Anticoagulation therapy was terminated by her family doctor 3 years previously. On admission, D-dimer level was 16.6 μg/mL and arterial blood gas showed 88.1% on room air. Pulmonary arteriography (PAG) revealed some filling defe...

Topography-guided neutralization technique for the management of flap complication in laser in situ keratomileusis

A 29-year-old male was referred following a flap loss after the creation of a thin, irregular flap with a visual acuity of logMAR 0.1 with -2.0 DS-2.75 DC × 175°. Corneal topography and anterior segment optical coherence tomography revealed an irregular corneal curvature and epithelial profile. Phototherapeutic keratectomy (PTK) followed by Topography - Guided Custom Ablation Treatment (TCAT), ...

Carbon dioxide column angioscopy: a new endovascular imaging technique.

A new angioscopic technique with a CO(2) gas medium for prolonged viewing sessions in the carotid artery is described. A stationary column of CO(2) gas, angled 17-30 degrees subhorizontally and buoyed against a balloon catheter, can be safely maintained. During 10-20-min sessions in dogs, endothelia, thrombi, stent filaments, coils, and an intimal flap were visualized. This technique eliminates...
