Central vein cannulation is one of the most commonly performed procedures in intensive care. Traditionally, the jugular and subclavian vein are recommended as the first choice option. Nevertheless, these attempts are not always obtainable for critically ill patients. For this reason, the axillary vein seems to be a rational alternative approach. In this narrative review, we evaluate the usefulness of the infraclavicular access to the axillary vein. The existing evidence suggests that infraclavicular approach to the axillary vein is a reliable method of central vein catheterization, especially when performed with ultrasound guidance...

Estimation of accurate maximum velocities and spectral envelope in ultrasound Doppler blood flow spectrograms are both essential for clinical diagnostic purposes. However, obtaining accurate maximum velocity is not straightforward due to intrinsic spectral broadening and variance in the power spectrum estimate. The method proposed in this paper for maximum velocity point detection has been developed by modifying an existing method-signal noise slope intersection, incorporating in it steps from an altered version of another method called geometric method...

Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible...

BACKGROUND: The majority of reports regarding general vascular access choices for apheresis procedures argue that peripheral venous access should be considered first. However, the clinical reality appears to be different. While some procedures mandate central vascular access (e.g., therapeutic apheresis procedures in critically ill patients) and in some cases it is the patient's preference, we propose that the majority of elective procedures can be successfully performed peripherally...

A healthy female presented with upper extremity (UE) swelling of several days duration. Admission laboratories were normal except for an elevated D-dimer. An UE ultrasound with Doppler revealed a thrombus in the right subclavian vein. A subsequent chest CT angiogram further characterised the subclavian vein thrombus and also identified a pulmonary embolus. A thorough history and laboratory evaluation showed that her only risk factors were long-time contraceptive pills and a recent cycle of ovarian hyperstimulation (OH) 7 weeks prior to presentation...

Central venous catheterization is a commonly used and important intervention. Despite its regular use it is still associated with a high incidence of complications especially infection and catheter tip embolization. Addition of ultrasound guidance to the technique has shown great improvement to the time and number of attempts for successful catheterization. The preference of vein depends greatly on the situation; subclavian vein is the preferred method overall but internal jugular vein is preferred in patients undergoing cardiac or thoracic surgery...

Yoo Kuen Chan, Pui San Loh
More than 90% of the human species are right handed. Although outwardly our body appears symmetrical, a 50/50% lateralization in handedness never occurs. Neither have we seen more than 50% left handedness in any subset of the human population. By 12-15weeks of intrauterine life, as many as 6 times more fetuses are noted by ultrasound studies to be sucking on their right thumbs. Distinct difference in oxygenation leading to dissimilar energy availability between right and left subclavian arteries in place by week 9 of life may hold the clue to the lateralization of hand function and eventually, the same in the brain...

BACKGROUND: Imaging the guidewire with ultrasonography in the internal jugular vein during central venous catheterization often is used to verify proper guidewire placement and to aid in prevention of inadvertent arterial catheterization. It is known, however, that inadvertent arterial catheterization can occur despite imaging the guidewire in the internal jugular vein because the guidewire may continue through the far wall of the internal jugular vein and into an adjacent artery. We propose confirmation of the guidewire in the brachiocephalic vein with ultrasonography as a more reliable method of confirming proper guidewire placement...

Kommerell's diverticulum (KD) is defined as a bulbous dilatation of the origin of an aberrant subclavian artery due to a remnant of the left fourth aortic arch. We report the case of an asymptomatic woman in whom progressive thrombosis of the KD extending to the prevertebral tract of an aberrant right subclavian artery was detected at multidetector computed tomography imaging for lung cancer staging performed before and after the beginning of chemotherapy. Reversed blood flow in the ipsilateral vertebral artery due to subclavian steal phenomenon was also observed by color Doppler ultrasound examination...

A 68-year-old female with no significant past medical history presented with loss of vision in the lower half of her left eye that lasted <5 minutes. No abnormalities were found on ocular or physical exam. Computed tomography angiography and carotid ultrasound were performed, which confirmed the diagnosis as amaurosis fugax with two abnormalities leading to the transient retinal vessel occlusion. First, it was found that the patient has a congenital vascular anomaly, which consisted most notably of a right-sided aortic arch...

Central venous catheterization through internal jugular vein is done routinely in intensive care units. It is generally safe, more so when the procedure is performed under ultrasound guidance. However, there could be inadvertent puncture of other vessels in the neck when the procedure is not performed under real-time sonographic guidance. Closure of this vessel opening can pose a challenge if it is an artery, in a location difficult to compress, and is further complicated by deranged coagulation profile. Here, we discuss the removal of an inadvertently placed catheter from subclavian artery with closure of arteriotomy percutaneously using arterial suture-mediated closure device...
