Surgical correction of coarctation of the aorta featuring an incomplete circle of Willis.

Although devastating complications during simple coarctation of aorta repair now occur less frequently, some unique cases still require extra caution. Here, we report a case of coarctation of the aorta with a rare anomaly in the circle of Willis and an aberrant right subclavian artery, which required a thorough surgical strategy that prevented cerebral malperfusion.

Surgical Resection of an Adventitial Cyst of the Right Brachiocephalic Vein.

Adventitial cystic disease is an uncommon vascular anomaly known to occur in peripheral vessels but mediastinal appearances are extremely rare. Herein, we report the case of an adventitial cyst occurring in the right brachiocephalic vein which might have been associated with ovarian hyperstimulation syndrome.

Successful surgical management for aneurysms of single coronary artery with a fistulous connection to the right ventricle.

While a coronary artery fistula with aneurysmal formation is rare, a fistula/aneurysm combination occurring in single coronary artery is even rarer. Here, we report the successful surgical correction of a right ventricular fistula with a large aneurysm of 30 mm and a daughter aneurysm within a case of single coronary artery.

Catastrophic cerebral infarction during extracorporeal life support due to a rare anomaly in the circle of Willis.

During extracorporeal life support (ECLS) in infants, cannulation of the right common carotid artery may result in a devastating ischaemic neurological injury. Herein, we present a case of an infant who encountered bilateral cerebral infarction during ECLS via the right carotid artery due to a rare and tragic anomaly of the circle of Willis. The magnetic resonance angiography complemented computed tomography in diagnosing the infarction and identifying this unique anatomy.

Surgical resection of enlarged calcification formed by idiopathic localized constrictive pericarditis during total aortic arch replacement for aortic dissection.

A 75-year-old woman presented at a prior hospital with persistent cough and was treated conservatively for a thrombosed-type aortic dissection (Stanford A). One-year after discharge, follow-up computerized tomography revealed a DeBakey type II, chronic dissecting aortic aneurysm enlarged to 54 mm. She was referred to our hospital with slight edema in the face and extremities and chest radiography showed calcification around the heart.

Cerebral Tissue Oxygenation Index Using Near-infrared Spectroscopy during Extracorporeal Cardio-pulmonary Resuscitation Predicted Good Neurological Recovery in a Patient with Acute Severe Anemia.

We herein report the clinical course of a patient who had a good neurological outcome despite severe anemia, high serum lactate levels, and a long period of time from cardiac arrest (CA) to extracorporeal cardio-pulmonary resuscitation (ECPR) establishment. During the period of resuscitation, the tissue oxygenation index (TOI) values were measured continuously by a near-infrared spectroscopy monitoring device and were kept within the normal range. The TOI seems to reflect cerebral perfusion and the balance between the oxygen supply and demand in the brain during ECPR, thereby predicting the neurological outcome.

Significant reversal of cardiac upregulated endothelin-1 system in a rat model of sepsis by landiolol hydrochloride.

Aims: Landiolol hydrochloride, an ultra-short-acting highly cardio-selective β-1 blocker, has become useful for various medical problems. Recent studies have demonstrated that co-treatment with landiolol protects against acute lung injury and cardiac dysfunction in rats of lipopolysaccharide (LPS)-induced systemic inflammation, and was also associated with a significant reduction in serum levels of the inflammation mediator HMGB-1 and histological lung damage. Endothelin (ET)-1, a potent vasoconstrictor, has been implicated in pathogenesis of sepsis and sepsis-induced multiple organ dysfunction syndrome.
