Digital subtraction angiography during transjugular intrahepatic portosystemic shunt creation or revision: data on radiation exposure and image quality obtained using a standard and a low-dose acquisition protocol in a flat-panel detector-based system

Abstract

Radiation exposure during TIPS creation/revision was significantly reduced by selecting a LDP in our flat-panel detector-based system, while maintaining adequate image quality.

Transjugular intrahepatic portosystemic shunt with transhepatic portal vein puncture guided by ultrasound: a technical alternative

“…In this study, the mean value for TIPS execution time was 65.2 ± 46.7 min below the reference standards and data obtained by David et al [25] that reached a TIPS execution time of 86 ± 41.7 min. This parameter was not mentioned in other publications [21][22][23][24]27].…”

“…[25] that reached a TIPS execution time of 86 ± 41.7 min. This parameter was not mentioned in other publications [21–24,27].…”

“…Although fluoroscopy time is not recommended for radiation monitoring by the international guidelines of the Society of Interventional Radiology-Cardiovascular Interventional Radiology European (SIR-CIRSE) [34], this time seems to reflect the complexity of the procedure and has been referred to in studies recently published [21][22][23][24][25].…”

“…Its morbidity is estimated at up to 20% and its mortality <2% [13,17,20]. This is one of the procedures with the greatest exposure to radiation for the patient and medical staff in interventional radiology [21][22][23][24]. The most demanding and generally limiting technical step of the procedure is the 'blind' puncture of the portal vein [4,[21][22][23]25,26].…”

A Smart Capsule System for Automated Detection of Intestinal Bleeding Using HSL Color Recognition

“…Clinical manifestations include vomiting and bloody diarrhea, and severe cases can cause shock or even death [5, 6]. Routine diagnosis methods for intestinal bleeding diseases, such as radionuclide scanning [7], digital subtraction angiography [8, 9], and endoscopic examination [10–12], generally are invasive or have substantial side effects, making physicians unlikely to administer them and patients unlikely to accept them [13, 14]. Capsule endoscopy represents a revolutionary breakthrough in noninvasive diagnosis of intestinal bleeding diseases [15].…”
