Recent studies have indicated that atherosclerosis-like changes are involved in the pathogenesis of aortic valve stenosis. Increased blood and valve tissue levels of C-reactive protein (CRP) have been reported in patients with aortic valve disease, although the different pathological conditions involved were not analyzed. The study aim was to monitor ...

The patient was a terminally ill 80-year-old man with multiple lung metastases from hepatocellular carcinoma, that had developed following hepatitis-C virus-associated cirrhosis. He was admitted to our hospital with gingival bleeding, and we diagnosed gingival metastasis from hepatocellular carcinoma, based on histological examination. The bleeding could not be controlled, and ...

Although many reports have shown that mediastinoscopy is an extremely safe procedure, the most serious complication that can occur is hemorrhage from the large vessels in the mediastinum. A patient with severe pulmonary artery injury during mediastinoscopy that was successfully repaired through a right posterolateral thoracotomy is reported. Digital compression ...

Vasoconstrictors such as norepinephrine and vasopressin are commonly used to raise the blood pressure during myocardial revascularization. The internal thoracic artery is commonly used for coronary artery grafting because of its long-term patency. However, the internal thoracic artery is a living conduit that responds to vasoactive substances. The objective of ...

Conventional surgical treatment of bilateral ophthalmic aneurysms would require bilateral craniotomies and bilateral neck dissections for proximal control of the cervical internal carotid artery (ICA). We present a semiemergent case where bilateral ophthalmic artery aneurysms were clipped using a unilateral mini-pterional craniotomy and contralateral proximal cervical ICA control while employing ...

Whether an arterial switch operation benefits patients with transposition of the great arteries and severe pulmonary hypertension (PH) remains controversial. Therefore, we evaluated the relationship between preoperative PH and early and midterm clinical outcomes after an arterial switch procedure. In this retrospective study, 101 consecutive patients with transposition of the ...

Exercise is thought to increase the diameter of the conduit arteries supplying the muscles involved. We studied the effects of a physically active vs inactive lifestyle on artery diameters in monozygotic (MZ) twin pairs discordant over 30 years for leisure-time physical activity habits. In a population-based co-twin control study design, ...

Several multicentre, randomized trials have validated the efficacy of carotid endarterectomy (CEA). Comparative randomized trials are also currently developing insight into the role of carotid angioplasty and stenting (CAS), and identifying factors for optimal patient selection. Although these interventions are aimed at embolic stroke prevention, anaesthetic management might prevent the ...

Vasospasm remains an extremely serious complication that affects patients presenting with subarachnoid hemorrhage (SAH) due to ruptured intracranial aneurysms. The current therapeutic armamentarium is still insufficient in many cases, and the search for new therapies is necessary. In this study, we evaluated the effect of N-acetylcysteine (NAC) on cerebral arterial ...

Vasomotor reactivity (VMR) represents the autoregulatory capacity of cerebral vessels and its clinical significance has been reported in steno-occlusive diseases of internal carotid artery (ICA). However, it has yet to be studied in intracranial steno-occlusive diseases. Consecutive patients with middle cerebral artery (MCA) stenosis diagnosed by MR angiography were compared ...

Vertebral artery dissecting aneurysm (VADA) is a relatively rare cause of subarachnoid hemorrhage (SAH). Bilateral VADAs are even rare, and management strategies for this type of VADAs are still controversial. Here, we report 3 cases of bilateral VADAs with SAH. All 3 patients were treated conservatively under strict sedation and ...

Perivascular tissue (PVT) surrounding many blood vessels, including those used as bypass conduits, is the source of adipocyte-derived relaxing factors, one of which is leptin. Here, we assessed leptin levels and identified leptin localization in the cushion of fat surrounding 'no-touch-harvested' saphenous veins (SVs) used as grafts in 15 patients ...

The intra-aortic balloon pump (IABP) is used worldwide as an anti-ischemic strategy and to reduce myocardial workload. However, whether IABP augments coronary flow after coronary bypass via a passive increase in diastolic pressure or an active response of the coronary bed remains uncertain. We analyzed transit-time flow measurements and the ...

So far the only endovascular option to treat patients with thoraco abdominal aortic aneurysms is the deployment of branched grafts. We describe a technique consisting of the deployment of standard off-the- shelf grafts to treat urgent cases. The sandwich technique consists of the deployment of ViaBahn chimney grafts in combination ...

Veins are still the best conduits available for arterial bypass surgery. When these arterialized vein grafts fail, it is often due to the development of intimal hyperplasia (IH). We investigated the feasibility and efficacy of the ex vivo pre-treatment of vein grafts with soluble carbon monoxide (CO) in the inhibition ...

Apolipoprotein(a) (apo(a)), a unique glycoprotein component of plasma lipoprotein(a) (Lp(a)),exhibits resistance to classical lipid-lowering treatments. Coronary artery bypass grafting (CABG) is commonly used to bypass coronary arteries diseased by atherosclerosis, routinely using the saphenous vein (SV) as a conduit. Early after grafting the SV adapts to the arterial environment through ...
