Abstract  Stenosis or occlusion of a large right coronary artery or its vein grafts in symptomatic patients who underwent previous bypass grafting procedure with patent left-sided grafts is mostly managed by percutaneous interventions. When percutaneous interventions fail, it is a difficult decision to reoperate on a such patient for a ...

The Hexalon system (Castlewood Surgical, Inc, Dallas, TX) is a new device that facilitates a clampless, hand-sutured, vein-to-aorta anastomoses in no-touch off-pump coronary artery bypass surgery. Hexalon-facilitated anastomoses are structurally equivalent to traditional sutured anastomoses, but can be placed during off-pump coronary artery bypass surgery. It follows that these facilitated ...

Long-term results of surgical myocardial revascularization are determined by the quality of grafts and the progression of atherosclerosis in coronary arteries. The aim of the study was to evaluate the patency rate of internal thoracic artery and great saphenous vein grafts in relation to the hemodynamic properties of revascularized coronary ...

Combined or tandem lesions of the common carotid artery and the ipsilateral carotid bifurcation are uncommon and the management of patients with this disease pattern can be challenging. The development of endovascular techniques has contributed a variety of options for managing these combined lesions; either as part of a hybrid ...

We describe the occurrence of the trigeminocardiac reflex (TCR) during DMSO pre-flushing of the microcatheter in preparation for Onyx embolization via the internal maxillary artery. TCR has not been previously associated with embolization of extradural entities. Familiarity with this clinical reflex and its proper management may help in planning neurointerventional ...

OBJECTIVE: It is unknown whether avoidance of cardiopulmonary bypass during coronary artery bypass grafting affects cerebral injury or long-term neuropsychological function. METHODS: Two hundred unselected patients were randomized to off-pump coronary artery bypass or on-pump coronary artery bypass grafting between March 2000 and August 2001. One hundred sixty-eight patients had ...

Institution of cardiopulmonary bypass after commencement of "off-pump" coronary artery bypass surgery is known as conversion. This may be an emergency or elective process. The phenomenon of conversion, although widely reported, remains under-emphasized. Emergency conversion may lead to poorer patient outcomes and therefore warrants serious consideration. The rate of conversion ...

Malpositioning of intravascular catheter is a known complication. We describe a case of a pregnant lady in whom dialysis catheter was inserted through the left internal jugular vein (IJV). It was molpositioned in the left internal mammary vein (IMV) which is very unusual site for a dialysis catheter. It was ...

OBJECTIVE: Neurologic complications after coronary artery bypass grafting remain a concern. Off-pump coronary artery bypass grafting is a surgical strategy proposed to decrease this risk. Use of an off-pump anaortic technique, which leaves the ascending aorta untouched, may result in further reductions. This systematic review of all published evidence compares ...

In a number of studies, centrifugal blood pumps-in comparison with roller pumps-have been shown to attenuate trauma to blood components. Nevertheless, the impact of these results on the postoperative course needs to be discussed controversially. In a prospective randomized study, 240 consecutive adult patients underwent elective myocardial revascularization with cardiopulmonary ...

A case is presented of a rare anterior inferior cerebellar artery variant, originating from the internal carotid artery. This mimicked a cerebellar infarct on vertebral angiography of a patient who presented with dysmetria and gait imbalance. It is important for the neuroradiologist and neurointerventionist to be aware of common and ...

Acute aortic occlusion is a rare but catastrophic pathology with high mortality even after revascularization. We describe four patients who underwent thrombectomy or bypass surgery for acute aortic occlusion with concomitant internal iliac artery occlusion. Two patients (82- and 75-year-old men), who had insufficient reperfusion of bilateral internal iliac arteries ...

Introduction. The hyperdense internal carotid artery sign (HICAS) has been suggested as a common marker of terminal internal carotid artery (ICA) thrombus associated with poor outcomes following thrombolysis. We aimed to investigate the prevalence and prognostic significance of the HICAS in an unselected cohort of patients receiving intravenous thrombolysis. Methods. ...

Off-pump coronary artery bypass graft surgery (OPCAB) has proven to be beneficial in many high-risk subgroups. This study aims to determine whether OPCAB lowers the incidence of pulmonary complications among patients with chronic lung disease (CLD) when compared with on-pump coronary artery bypass graft surgery (ONCAB). From 2002 to 2007, ...

Mesenterico-left portal vein (meso-Rex) bypass is as an effective modality for restoring intrahepatic portal perfusion in patients with extrahepatic portal vein obstruction. Achieving sufficient patency is difficult with end-to-side anastomosis of a bypass graft to a small or hypoplastic left portal vein in the Rex recessus. Here, we describe the ...

We successfully created a percutaneous transhepatic portacaval shunt under ultrasonography (US) guidance in a 46-year-old man with refractory ascites. The shunt was created to salvage an attempt to create a transjugular intrahepatic portosystemic shunt (TIPS) that failed because of the elevated level of portal vein bifurcation due to alcoholic liver ...
