Cannulation Of The Axillary Artery For Cardiopulmonary Bypass: Safeguards And Pitfalls., Michael C Sinclair, Raymond Singer, Norman J Manley, Ralph M Montesano

Raymond L Singer MD

BACKGROUND: The ascending aorta is the customary site for arterial cannulation for cardiopulmonary bypass. Favorable experience at our institution and elsewhere using axillary artery cannulation in treating type A aortic dissections has caused us to broaden our indications for using this site for arterial cannulation for cardiopulmonary bypass.

METHODS: Medical records, operative notes, and perfusion records were reviewed in all patients in whom the axillary artery was cannulated directly or by a graft for cardiopulmonary bypass from January 1, 2000 through August 30, 2002.

RESULTS: Seventy-five patients underwent axillary artery cannulation during the 32-month interval. Eleven patients had ascending aortic …

Complications From Heparin-Induced Thrombocytopenia In Patients Undergoing Cardiopulmonary Bypass., Raymond Singer, J D Mannion, T L Bauer, F R Armenti, R N Edie

Raymond L Singer MD

The purpose of this study was to evaluate retrospectively the incidence and severity of heparin-induced thrombocytopenia (HIT)-related complications in patients undergoing cardiopulmonary bypass. We reviewed the records of 1,500 consecutive patients who underwent cardiopulmonary bypass between August 1987 and December 1991 at Thomas Jefferson University Hospital. During this period of time, there were 1,155 coronary artery bypass graft operations (77 percent); 225 valve replacements and repairs, or both (15 percent); 60 combination coronary artery bypass graft or valve operations, or both (4 percent); and 60 miscellaneous procedures (4 percent). Although not all patients with postoperative complications were tested for the …

Thoracoscopic Excision Of A Malignant Schwannoma Of The Intrathoracic Vagus Nerve., Raymond Singer

Raymond L Singer MD

Malignant schwannomas of the intrathoracic vagus nerve are rare tumors. A patient underwent resection of a mediastinal malignant schwannoma of the vagus nerve using video-assisted thoracoscopy, with no recurrence at 18 months.

Extra-Anatomic Redo Of Midcab And Opcab: An Early Experience., M C Sinclair, M Leboutillier, W Gee, Theodore Phillips, Raymond Singer

Raymond L Singer MD

BACKGROUND: Eighteen patients with unstable angina underwent repeat myocardial revascularization without cardiopulmonary bypass using saphenous vein grafts from either the left (13) or right (2) axillary arteries or the descending thoracic aorta (3). Patients' ages ranged from 53 to 85 years. Left ventricular ejection fractions ranged from 15% to 60%. METHODS: In 14 patients, the heart was exposed through an anterior thoracotomy, a minimally invasive direct coronary artery bypass (MIDCAB) technique. In 3 patients a left posterolateral thoractomy (lateral MIDCAB) was performed. One patient underwent repeat sternotomy (off-pump coronary artery bypass: OPCAB). In MIDCAB and lateral MIDCAB patients, the "target" …

Outcome Of Blunt Thoracic Aortic Injury In A Level I Trauma Center: An 8-Year Review., E J Frick, M D Cipolle, Michael Pasquale, T E Wasser, M Rhodes, Raymond Singer, S A Nastasee

Raymond L Singer MD

BACKGROUND: The purpose of this study was to evaluate our experience with blunt thoracic aortic injury and identify factors predictive of outcome. METHODS: Hospital charts, trauma registry data, and autopsies of 64 patients with blunt thoracic aortic injury from 1988 to 1995 were reviewed. RESULTS: Patients were identified and segregated based on admission physiology. Group 1 patients (n = 19) arrived in arrest. Group 2 patients (n = 10) arrived in shock with systolic BP 90. Group 3 patients (n = 35) arrived with systolic BP>90. All patients in groups 1 and 2 expired. Injury Severity Scores for nonsurvivors …

Identification Of Experimentally Induced Colitis By In Vitro Nuclear Magnetic Resonance., R H Rolandelli, S H Saul, R G Settle, D O Jacobs, Raymond Singer, G L Wolf, J L Rombeau

Raymond L Singer MD

The present study determined whether in vitro nuclear magnetic resonance could be used to assess experimentally induced colitis in rats. Acute colitis was induced in 6 Sprague-Dawley rats by acetic acid enema, while 6 control animals received saline enemas. All animals were sacrificed 24 hours post-enema, and NMR relaxation times, T1 and T2, of colonic samples were determined on a 10 MHz spin analyzer (RADX, Houston, TX). Colonic water content was determined on the same samples by desiccation. Colitis animals showed significantly higher T1 and T2 relaxation times and tissue water content than controls. T1 and T2 times correlated significantly …

Surgical Treatment Of Multiple Vein Graft Aneurysms In 72 Year Old Man, Heather Geist, James K. Wu Md, Raymond Singer Md

Raymond L Singer MD

Abstract

The rarity of saphenous vein graft aneurysms following coronary artery bypass graft surgery presents an interesting case, as seen in a 72 year-old gentleman who underwent his third bypass surgery for an aneurysmal graft. Information regarding the case was gathered using the Lehigh Valley Health Network medical databases. The 8 cm aneurysmal portion of the graft was resected successfully and replaced with a CryoVein. Following surgery the patient had relief of symptoms and recovered well. It was determined that the patient had two true aneurysms present, making surgery a necessity in this specific case.

Stakeholder Perspective: Cardiovascular Safety Of Azithromycin Therapy: Revisiting The Evidence, Raymond Singer

Raymond L Singer MD

BACKGROUND: Azithromycin has been used for many years for the treatment of patients with various types of bacterial infections, as well as for the secondary prevention of coronary events. There is a growing concern, however, that azithromycin may be associated with an increased cardiovascular (CV) risk and may lead to CV-related death in high-risk patients. OBJECTIVE: This systematic review of randomized controlled trials was conducted to analyze and describe the CV risk and safety outcomes associated with azithromycin therapy. METHODS: A meta-analysis was conducted based on the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials databases from 1990 through …

Stakeholder Perspective: The Clinical Toll Of Nonvalvular Atrial Fibrillation Poses Significant Economic Burden, Raymond Singer

Raymond L Singer MD

BACKGROUND: Understanding the economic implications of oral anticoagulation therapy requires careful consideration of the risks and costs of stroke and major hemorrhage. The majority of patients with atrial fibrillation (AF) are aged ≥65 years, so focusing on the Medicare population is reasonable when discussing the risk for stroke. OBJECTIVE: To examine the relative economic burden associated with stroke and major hemorrhage among Medicare beneficiaries who are newly diagnosed with nonvalvular atrial fibrillation (NVAF). METHODS: This study was a retrospective analysis of a 5% sample of Medicare claims data for patients with NVAF from 2006 to 2008. Patients with NVAF without …
