The internal jugular vein is often used for central venous catheter placement. The variations in the location of this vein along the major neck vessels (in the carotid sheath) may account for unsuccessful cannulations or iatrogenic arterial injuries. The aim of this study was to delineate the relation of the ...

It is commonly believed that in vein of Galen aneurysmal malformations (VGAMs) venous structures normally constituting the deep or Galenic venous system, such as the internal cerebral vein (ICV) and the basal vein of Rosenthal, are not connected to the vein of Galen. In this report, the authors describe 2 ...

The standard surgical procedure for esophageal cancer is transthoracic esophagectomy with en bloc resection of the azygos vein, thoracic duct and mediastinal lymph nodes. To reduce morbidity of esophago-lymphadenectomy, minimally invasive techniques are increasingly being applied. In (robot-assisted) thoracoscopic esophagolymphadenectomy, the azygos vein is generally left in place, as the ...

Knowledge of the varying drainage patterns of superficial veins of head & neck, in particular, jugular veins are not only important for anatomists but also for the surgeons operating at this level and to clinicians in general. The variations are important also for interventional radiologists, who perform trans-jugular procedures, such ...

Anatomic variants of the inferior vena cava (IVC) can make selective catheterization of the spermatic vein difficult. In an attempt to embolize the left varicocele, the authors identified a duplicated IVC on an initial venogram through the right common femoral vein. However, it was not possible to cannulate the left ...

Central venous cannulation is a routine procedure. We describe a rare complication of internal jugular vein catheterization leading to radiculopathy of the right upper arm. MRI of the neck showed compression of the spinal cord and C2-C7 roots by the engorged veins. Digital subtraction angiography demonstrated a fistula between subclavian ...
Pyrzowski J - - 2007
The posterior thoracic wall, an area drained by the azygos venous system, is a common site for surgical intervention. Since the venous part of the cardiovascular system is subject to most common variation, abnormalities in the azygos venous system are often reported. Some of the anatomical variants have significant clinical ...

Central vein occlusion (CVO) is not uncommonly observed after hemodialysis (HD) catheter placement and it may prevent subsequent ipsilateral arteriovenous (AV) access creation. Right internal jugular vein catheterization (RJVC) appears to be the insertion site with the lowest incidence of CVO, but little is known about the incidence of CVO ...

PURPOSE: To determine if large caliber accessory veins are associated with radial-cephalic arteriovenous fistula (RC-AVF) non-maturation. METHODS: RC-AVFs were created in 15 consecutive patients (radial artery and cephalic vein diameter > 2 mm, in the absence of arterial inflow or venous outflow stenoses or occlusions). Contrast-enhanced magnetic resonance angiography (CE-MRA) ...

Internal jugular vein is the preferred route for central venous cannulation because of easy accessibility and high success rate. Arterial puncture is the most common complication, the reported incidence being 9.3%. However, brachial plexus palsy following arterial puncture is a rare complication of this procedure. We report a case of ...

The circulatory system consists of veins and arteries. Compared with arteries, veins have been neglected in cardiovascular research. Although veins are significantly less muscular than similarly sized arteries, the contribution of veins to cardiovascular homeostasis cannot be left un-noted because veins accommodate 70% of the circulating blood. Circulating blood platelets ...

BACKGROUND: Transplanting a vascularized autologous submandibular gland (SMG) is considered an effective method to treat severe keratoconjunctivitis sicca. But the operation may fail due to the anatomic variances in the blood vessels of SMG. The present study aimed to investigate the submandibular glands at the microanatomy level. METHODS: The microanatomy ...

The causes of the regional differences in venous grafts patency rates are partially understood. Differences in vein dynamics during physiological situations could determine differences in veins' capability to face arterial conditions and could contribute to the dissimilar performance of veins as arterial grafts. In vitro pressure and diameter were measured ...

The facial artery has been proposed as the main vascular pedicle in facial transplantation. An anatomic study of 200 consecutive facial and transverse facial vessels in 100 normal individuals was performed using color Doppler ultrasound. The diameter and course of each facial vessel were measured at 3 fixed landmarks, and ...

The nutcracker phenomenon refers to compression of the left renal vein at the origin of the superior mesenteric artery and is often underdiagnosed. This can cause symptoms of pelvic venous congestion with retrograde venous flow and a dilated gonadal vein. Here we describe a case in a 39-year-old female, who ...

Vascular leiomyosarcoma is extremely rare and represents < 2% of all leiomyosarcomas. The frequency of occurrence of leiomyosarcomas in veins is five times more than in arteries, with approximately half of them occurring in the inferior vena cava. Although leiomyosarcomas originating from large arteries or veins have been widely reported, ...

Peduncular hallucinosis is characterized by striking visual images, highly colored and mobile, which are recognized by the patient as imaginary. A 50-year-old-man underwent microvascular decompression for a classical right sided trigeminal neuralgia. During the procedure, the petrosal vein and a transverse pontine vein were sacrificed for trigeminal decompression. On the ...

BACKGROUND: Imaging the coronary venous (CV) tree to delineate the coronary sinus and its tributaries can facilitate electrophysiological procedures, such as cardiac resynchronization therapy (CRT) and catheter ablation. Venography also allows visualization of the left atrial (LA) veins, which may be a potential conduit for ablative or pacing strategies given ...

Facial region is drained by the maxillary, facial and superficial temporal veins. In the present case, retromandibular venous junction divided into anterior and posterior divisions immediately after its formation and a common venous channel was formed between internal jugular and anterior jugular veins where facial, lingual and submental veins drained.

A patient with occlusion of multiple central veins from both dialysis and nondialysis catheters required permanent access for hemodialysis. Magnetic resonance imaging showed a patent left innominate vein. He underwent creation of a left axillary artery to internal mammary vein transposition fistula using the basilic vein from his right arm. ...

OBJECT: The mesencephalic veins drain crucial brainstem areas. Due to the narrowness of the tentorial notch, these veins can become obstructed as a result of herniation or surgery, leading to hemorrhage and severe consequences for the patient. There is little in the literature about the mesencephalic veins. The aim of ...

STUDY OBJECTIVE: The purpose of this study is to compare ultrasonographic visualization of the jugular and common femoral veins by using a novel technique (humming) and 2 conventional techniques (Valsalva's maneuver and Trendelenburg's position). The Valsalva's maneuver and Trendelenburg's position are common methods for producing venous distention, aiding ultrasonographically guided ...

BACKGROUND: The purpose of the study was to show that the delayed venous method provides a high success rate in distal phalanx replantation, and does not require the use of specialised techniques. Vein anastomosis is the most important factor determining the 'take rate' in treatment of distal phalanx amputation. However, ...
Downie S A - - 2007
A rare bilateral duplication of the internal jugular vein (IJV) was discovered during cadaveric dissection. From each jugular foramen, a single IJV descended to the level of the hyoid bone then divided into medial and lateral veins. The medial IJVs traveled in the carotid sheath; the lateral IJVs coursed posterolateral ...

The demographic characteristics of hemodialysis (HD) patients increase the need for the tunneled cuffed permanent catheter (TCC) as a definitive vascular access (VA) for HD. The internal jugular vein is increasingly being used as a route for TCC or temporary catheter placement and can be associated with serious complications. Among ...
