From October 1982 through February 1985, six patients have undergone seven reoperative revascularization procedures for stenosis of coronary artery vein bypass grafts without the use of cardiopulmonary bypass or intraoperative shunt. All patients had prior coronary artery saphenous vein bypasses, ranging from 2 months to 5 years preoperatively. All patients survived reoperation and there was no morbidity. Patients have been followed-up to 26 months. One patient underwent postoperative cardiac catheterization at 1 year, which revealed a patent interposition graft, and one patient had a second operation for restenosis of a vein graft. To decrease the risk of morbidity and mortality in reoperative procedures for saphenous vein graft stenosis, a technique is described that avoids the use of cardiopulmonary bypass or intraoperative shunt. This technique has been used successfully for seven reoperative revascularization procedures and is recommended for selected cases.

Association between white blood cell count and coronary artery bypass graft failure: an individual patient data analysis of clinical trials.
J Cardiothorac Surg
January 2025
Department of Cardiothoracic Surgery, Weill Cornell Medicine, 525 E 68th St, New York, NY, 10065, USA.
Background: Baseline systemic inflammation is associated with worse long-term outcomes after coronary artery bypass grafting [CABG], but the mechanisms of this association are unclear. This study aims to explore the association between pre-operative white blood cell [WBC] count and CABG graft failure.
Methods: We pooled individual patient data from two randomized clinical trials with systematic CABG graft imaging.
A Rare Case of Linear Phlebolith: Foreign Body Discovered in the Femoral Vein.

Phlebolith is a term that refers to round-shaped calcified thrombi commonly located in the pelvic region. The occurrence of dense, linear calcifications or phlebolith-like formations within the soft tissues of the lower extremities, particularly in the superficial femoral, greater saphenous, or popliteal veins, is rare. This study presents the case of a 73-year-old woman who was being evaluated for postmenopausal bleeding.

Objective: The aim of this study was to compare anterior accessory saphenous vein (AASV) reflux after standard endovenous laser ablation (EVLA) vs. flush EVLA (fEVLA) of the great saphenous vein (GSV).
Methods: This was as randomised, single blind, controlled trial (Dutch Trial Register, NL5283).
Validation of BEST-CLI among patients undergoing primary bypass or angioplasty with or without stenting for chronic limb-threatening ischemia.

Department of Surgery, Division of Vascular and Endovascular Surgery, Beth Israel Deaconess Medical Center, Harvard Medical School, Boston, MA. Electronic address:
Background: BEST-CLI established the superiority of single-segment great saphenous vein (ssGSV) conduits for revascularization in patients with CLTI; however, the generalizability of these data is unknown. Thus, we aimed to validate the long-term results of open surgical bypass (BPG) versus angioplasty with or without stenting (PTA/S) using the BEST-CLI inclusion and randomization criteria.
Methods: All patients undergoing a first-time lower extremity revascularization for CLTI at our institution from 2005 to 2022 were retrospectively reviewed.
Emergency carotid endarterectomy with stent retrieval in a patient with stent migration following failed carotid artery stenting.

Carotid artery stenting (CAS) has become a favoured alternative to surgical carotid endarterectomy (CEA) in select cases of critical internal carotid artery (ICA) occlusion. However, complications such as stent migration or entrapment can occur, necessitating prompt diagnosis and intervention. We present a case of a 75-year-old diabetic male who underwent CAS for recurrent presyncope at a private hospital, and during the procedure of CAS the stent was migrated and its proximal part was impacted in the critically narrowed part of the ICA.
