Use of Color Doppler Ultrasound in the Diagnosis and Treatment of Iatrogenic Subclavian Artery Pseudoaneurysm

Pseudoaneurysms resulting from inadvertent cannulation of the subclavian artery are rare, with only three prior cases reported in the English literature. Generally, they have required surgical correction. We present a case of a right subclavian artery pseudoaneurysm resulting from an unsuccessful attempt at cannulation of the right internal jugular vein by the middle approach. In this patient, successful closure of the pseudoaneurysm was accomplished with prolonged manual compression guided by vascular ultrasound and Doppler color flow imaging.

Standards for the development and methodology of the 2019 International Working Group on the Diabetic Foot guidelines

Diabetic foot disease is a source of major patient suffering and societal costs. Investing in evidence‐based international guidelines on diabetic foot disease is likely among the most cost‐effective forms of health care expenditure, provided the guidelines are outcome focused, evidence based, and properly implemented. The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2019 updates are based on formulating relevant clinical questions and outcomes, rigorous systematic reviews of the literature, and recommendations that are specific, and unambiguous along with their transparent rationale, all using the Grading of Recommendations Assessment Development and Evaluation (GRADE) framework. We herein describe the development of the 2019 IWGDF guidelines on the prevention and management of diabetic foot disease, which consists of six chapters, each prepared by a separate working group of international experts. These documents provide guidelines related to diabetic foot disease on prevention; offloading; peripheral artery disease; infection; wound healing interventions; and classification of diabetic foot ulcers. Based on these six chapters, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field. We believe that adoption and implementation of the 2019 IWGDF guidelines by health care providers, public health agencies, and policymakers will result in improved prevention and management of diabetic foot disease and a subsequent worldwide reduction in the patient and societal burden this disease causes.     

Systematic Evaluation of Vascular Access by Color‐Doppler Ultrasound Decreased the Incidence of Emergent Vascular Access Intervention Therapy and X‐Ray Exposure Time: A Single‐Center Observational Study

Arteriovenous fistula has superior patency over other accesses, but vascular access intervention therapy (VAIVT) for stenosis or thrombosis still remain major reasons for hospital admission of dialysis patients. The aim of this study was to examine the usefulness of systematic evaluation of vascular access by color‐Doppler ultrasound (CDUS). This study was a single‐center observational design study. We planned screening CDUS to evaluate all vascular accesses once per year, and additionally, follow‐up CDUS of post‐interventional patients 1 month, 3 months and 6 months after their recent VAIVT. This systematic evaluation was started from September 2009. The observational period between September 2008 and August 2009 was defined as period A. The observational period between September 2009 and August 2010 was defined as period B. We compared the incidence of emergent VAIVT and X‐ray exposure time during the period A to B. 131 patients with AV fistula were assigned. 13 patients were excluded due to death, hospital transfer or re‐operation of their accesses. During period A, 57 VAIVTs were carried out, and 37 cases (65%) were emergent. During period B, 42 VAIVTs were carried out, and 11 cases (25%) were emergent. The incidence of emergent intervention therapy was lower during period B than period A (P < 0.001). The amount of X‐ray exposure time per patient was decreased in patients who received VAIVT during both periods (P < 0.03). Systematic evaluation of vascular access by CDUS decreased the incidence of emergent VAIVT and X‐ray exposure time.

Influence of the Spleen on Portal Haemodynamics: a Non-invasive Study with Doppler Ultrasound in Chronic Liver Disease and Haematological Disorders

Background: Splanchnic haemodynamic parameters for the differential diagnosis of splenomegalies of different origins are still suboptimal and the role of spleen enlargement in cirrhosis remains controversial. In an attempt to elucidate these questions, we assessed splanchnic haemodynamics in chronic liver diseases and various other disorders with splenomegaly. Methods: Study groups comprised: (i) patients with chronic liver disease (89 with cirrhosis, 35 with chronic hepatitis), (ii) patients with splenomegaly without relevant portal hypertension (14 with haematological splenomegaly and 25 liver transplant recipients without complications), (iii) 15 patients with arterial hypertension, (iv) 22 healthy controls. In all subjects, spleen size, portal flow parameters and splenic artery resistance index were measured using duplex-Doppler ultrasound. Results: Splenic artery resistance index was significantly and selectively increased in patients with cirrhosis (0.63, whereas all other group means ranged between 0.53 and 0.56; P < 0.01). Portal flow velocity was significantly decreased in cirrhosis ( P < 0.01). The combination of these two parameters provided an accuracy of 87.5% in distinguishing portal hypertensive from haematological splenomegaly. In patients with cirrhosis, the degree of spleen enlargement was positively correlated with increasing portal flow volume, portal vein diameter and variceal size, whereas splenic resistance index and portal velocity did not differ in connection with spleen size. Conclusions: Splenoportal Doppler sonography provides specific findings in cirrhosis and may therefore be a useful tool in differentiating between splenomegaly of portal hypertensive or haematological origin. In patients with cirrhosis, the presence of splenomegaly is associated with the presence of larger oesophageal varices.
