Carotid endarterectomy (CEA) is the standard of care for patients with high-grade carotid artery stenosis who are acceptable surgical candidates. Focal occlusive lesions of the origin of aortic arch vessels can be effectively and safely treated with balloon angioplasty and primary stenting. The purpose of this study was to retrospectively review results of carotid endarterectomy for high-grade carotid bifurcation stenosis combined with intraoperative retrograde transluminal angioplasty and primary stenting of a hemodynamically significant stenosis at the origin of a proximal ipsilateral aortic arch vessel. ⋯ Carotid endarterectomy with balloon angioplasty and primary stenting of an ipsilateral hemodynamically significant aortic arch trunk vessel stenosis can be safely and successfully accomplished and avoids the need for an intra/extrathoracic bypass procedure.

A man presented with acute chest and back pain with loss of consciousness. CT scan showed a mass in the arch that extended into the descending aorta. A diagnosis of type I aortic dissection was ultimately made by echocardiography. At surgery there was a circumferential intimal tear in the aortic root, and an intussuscepted dissection flap was retrieved from the arch and descending aorta.

In the assessment of fluid status after cardiac surgery, we applied bioelectrical impedance analysis (BIA) to measure the total body water (TBW), extracellular fluid (ECF), and intracellular fluid (ICF), and evaluated its validity. ⋯ It was considered that BIA was useful for evaluating the relative changes in TBW and fluid distribution, and ECF/ICF might be a new parameter for abnormal water metabolism after cardiac surgery.

Comparative Study
Usefulness of transesophageal echocardiography during open heart surgery of mitral stenosis.
The aim of this study was to verify if the use of intraoperative transesophageal echocardiography (TEE), by detecting mitral insufficiency or residual stenosis during surgery, may improve medium term results in patients with severe mitral stenosis who undergo open heart valvuloplasty. ⋯ Intraoperative TEE may guide the surgeon in the assessment of valvuloplasty. However the absence of mitral regurgitation after repair and at discharge cannot predict the medium term results, which are related to the degree of the disease of the mitral valve.

Major vascular injuries in the region of the neck are most frequently the result of penetrating trauma. Evaluation and management of patients with injury to Zone II of the neck remains highly controversial. Most studies involve small number of patients with a lack of standardization of the nature of the injury in reporting outcome. It is the purpose of this study to propose a grading scale for vascular injuries in the neck that would allow for more uniform reporting of such injuries. ⋯ Carotid artery injuries occur in about 17% of patients with penetrating neck trauma. Data regarding management and prognosis in these patients are at best concflicting, in part, due to lack of a standardized classification system. The proposed grading scale is designed to overcome this problem.
