Patient Evaluation and Preparation in Vascular and Interventional Radiology: What Every Interventional Radiologist Should Know (Part 1: Patient Assessment and Laboratory Tests)

Abstract

Performing an interventional procedure imposes a commitment on interventional radiologists to conduct the initial patient assessment, determine the best course of therapy, and provide long-term care after the procedure is completed. After patient referral, contact with the referring physician and multidisciplinary team approach is vital. In addition, clinical history, physical examination, as well as full understanding of the pre-procedural laboratory results and imaging findings can guide the interventional radiologist to implement the most appropriate management plan, avoid unnecessary procedures, and prevent complications to achieve a successful outcome. We provide a comprehensive, methodical review of pre-procedural care and management in patients undergoing vascular and interventional radiology procedures.

Ultrasound-guided percutaneous laser ablation is safe and effective in the treatment of small renal tumors in patients at increased bleeding risk

“…Instead, in our series, LA was performed under US-guidance by using very thin needles. The kidney is a hypervascular organ and is considered more at risk of bleeding than the liver when interventional procedures are performed [37,38], and needle size has been reported to be a risk factor of hemorrhagic complications [39,40]. Therefore, the use of thinner needles could provide some advantage when thermal ablation is performed to treat RCC, in particular if the risk of bleeding is increased.…”

Role of Venous Sampling in the Diagnosis of Endocrine Disorders

“…Patients with persistent or recurrent PHPT after surgery may require PVS to localize abnormal glands. Because most patients have had prior invasive neck exploration prior to PVS, understanding the surgical procedures and imaging findings is essential [ 52 , 53 ].…”

Performing an Ultrasound-Guided Percutaneous Needle Kidney Biopsy: An Up-To-Date Procedural Review

“…The examination must be completed with an ECD assessment to rule out the presence of vessels along the presumed path of the needle (Figure 3). Vascular abnormalities are reported in up to 10% of patients who undergo renal biopsy, and this may explain the reduction in complications observed when an ECD study preceded the procedure [15]. An ultrasound-guided PRB can be performed either freehand or with the aid of needle supports to force its trajectory (needle-guided insertion).…”
