Venous malformations of the jugular veins are rare findings. Aneurysms and phlebectasias are the lesions most often reported. We report on an adult patient with an abruptly appearing large tumorous mass on the left side of the neck identified as a jugular vein aneurysm. Upon clinical examination with ultrasound, a ...

PURPOSE: Off-pump coronary artery bypass grafting surgery (OPCAB) frequently results in significant jugular bulb desaturation. Although jugular bulb desaturation during OPCAB may be associated with postoperative cerebral injury, routine jugular bulb oximetry appears to be invasive and expensive. We hypothesized that intraoperative hemodynamic compromise during OPCAB due to cardiac displacement ...

We intend to show the MDCT findings of normal ovarian (gonadal) vein anatomy and associated disorders, including the "ovarian vascular pedicle" sign, phlebolith, reflux, pelvic congestion syndrome, thrombosis, stenosis, and occlusion. Volume-rendered images and curved planar reformatted images can be used to show the ovarian veins. MDCT findings allow the ...

Diastolic dysfunction is usually identified by the combination of characteristic mitral and pulmonary vein flow patterns. However, obtaining a complete set of echocardiographic parameters can be technically difficult and data may conflict. We hypothesized that as a stand-alone variable, (ventricular) diastolic dominant pulmonary vein flow would predict heart failure (HF) ...

The macroscopic features of the venous drainage of the reproductive system of the male ostrich were studied in six pre-pubertal and three sexually mature and active birds. Each testis was drained by one to four testicular veins. The right testicular veins drained the right testis and epididymis and its appendix ...

Ingested foreign bodies are a fairly common otorhinolaryngological emergencies encountered in Malaysia. The vast majority of these foreign bodies are fish bones which most commonly are impacted at the level of the cricopharynx. Rarely, however, a foreign body may migrate extraluminally and may even extrude subcutaneously. We report a rare ...

Carotid-ophthalmic fistula is a rare disease, which can be treated by transvenous endovascular embolization. Here, we report a unique case with draining vein thrombosed, making a transvenous approach impossible. An old but valuable technique, direct transcutaneous puncture of the superior ophthalmic vein, was used to save the patient's right eye. ...

When the superficial femoral vein is obstructed by thrombosis, the profunda femoris vein provides an important collateral pathway, transforming into the axial vein of the lower limb. When operating on a transformed axial vein, a surgeon should be aware of the formation, the relations and the course of the vein. ...

Laparoscopic adrenalectomy (LA) is the procedure of choice for most adrenal tumors. An important part of LA is the early identification and ligation of the adrenal veins. The venous drainage from each adrenal gland is usually via a single vein: the right vein draining into the inferior vena cava (IVC) ...

OBJECTIVE: Venous compression might be the main cause of incomplete decompression and symptom recurrence after microvascular decompression (MVD) in patients with trigeminal neuralgia. Although it can be killed in most cases, cutting the vein sometimes has the potential risk arising from venous congestion. To maneuver the vein safely, we introduced ...

Although neurofibromatosis type 1 (NF-1) is commonly considered neurocutaneous, severe arterial and venous abnormalities have been noted. Our patient, a 28-year-old woman, had bilateral giant extracranial aneurysms of the internal carotid arteries as well as skull base meningoceles involving the jugular foramina and aberrant jugular veins. CT and MR imaging, ...

Arterial vein grafts (AVGs) often fail due to intimal hyperplasia, thrombosis, or accelerated atherosclerosis. Various approaches have been proposed to address AVG failure, including delivery of temporary mechanical support, many of which could be facilitated by perivascular placement of a biodegradable polymer wrap. The purpose of this work was to ...

Thoracic vein aneurysms are very rare vascular lesions, usually detected as incidental findings. We describe the case of a patient with an advanced atrioventricular block who underwent definitive pacemaker implantation. In order to explain the difficult advancement of a pacemaker lead, vein angiography was performed during the procedure and a ...

BACKGROUND: The major determinant of atrial fibrillation (AF) initiation is focal firing within the muscular portion of the pulmonary veins. We hypothesized that interstitial Cajal cells (ICCs), a known type of pacemaker cells, could underlie the pacemaking activity of isolated pulmonary veins. OBJECTIVE: The aim of the study was to ...

PURPOSE: Hemodialysis patients with suspected central vein stenosis or occlusion require venographic assessment before access surgery. Conventional venography may be unsatisfactory because of the limited ability to image central veins via peripheral arm veins that are inadequate or that have been damaged by multiple cannulations. Imaging of the central veins ...

BACKGROUND: Management of congenital pulmonary vein stenosis is a diagnostic challenge. Echocardiography may be insufficient and thus cardiac catheterization remains the reference standard in this setting. The aim of the study was to investigate the accuracy of cardiac-non-gated CT using 64-slice technology in detecting congenital pulmonary vein stenosis in children. ...

Internal jugular vein thrombosis is an uncommon entity with high morbidity and an increased risk of mortality. Spontaneous clotting of the internal jugular vein without any known risk factors is virtually unheard of, and intravenous drug use is the most common cause for thrombosis. Assisted reproductive techniques alone or in ...

We hypothesized that the 5-hydroxytryptamine (5-HT; serotonin) system is present and functional in veins. In vena cava (VC), the presence of the 5-HT synthesis rate-limiting enzyme tryptophan hydroxylase-1 mRNA and accumulation of the 5-HT synthesis intermediate 5-hydroxytryptophan after incubation with tryptophan supported the ability of veins to synthesize 5-HT. The ...

OBJECTIVE: We sought to describe the juxtacondylar approach to jugular foramen tumors. METHODS: Through an anterolateral approach, the third segment of the vertebral artery (between C2 and the dura mater) is controlled. The C1 transverse process of the atlas, which is located just inferiorly to the jugular foramen, is then ...

BACKGROUND AND OBJECTIVES: Cannulation of a central vein is an everyday procedure in anaesthesiology. However, anatomical variations of the size and/or location of the internal jugular vein might prevent cannulation, while repeated efforts might lead to severe complications. The aim of this retrospective study was to explore anatomical abnormalities of ...
