Incidence and Clinical Course of Limb Dysfunction Post Cardiac Catheterization - A Systematic Review

Investigating optimal compression approach following radial artery puncture: a retrospective study

BACKGROUND

The method for compressing hemorrhagic sites after transradial access has been a topic of interest, yet definitive guidelines remain elusive. This study aims to address this gap by optimizing the mechanical compression hemostasis protocol after transradial access.

METHODS

This retrospective analysis included 300 patients from the Department of Cerebrovascular Diseases, Shanghai Fourth People's Hospital affiliated to Tongji University, who underwent transradial access for cerebrovascular angiography. Following the procedure, patients received radial artery compression hemostasis using a balloon compressor. They were divided into group A (n=100, continuous deflation) and group B (n=200, intermittent deflation) according to different hemostasis methods. The incidence of bleeding at the puncture site and complications were compared between the two groups.

RESULTS

The rate of bleeding at the puncture site was significantly lower in group B (20 out of 200 patients) compared to group A (20 out of 100 patients) (P=0.032). Similarly, the incidence of puncture site complications, such as edema, congestion, and wound infection was lower in group B (5 out of 200 patients) compared to group A (10 out of 100 patients) (P=0.006).

CONCLUSION

Four hours of compression with intermittent deflation (group B) emerged as the optimal compression method after transradial access, demonstrating fewer complications at the patient's puncture site.

Comparison of the effects of three kinds of hand exercises on improving limb function in patients after transradial cardiac catheterization

Objectives

This study aimed to compare effects of different hand exercises on improving limb function in patients after transradial cardiac catheterization.

Methods

This single-center, randomized clinical trial was conducted from August 20, 2020, to July 20, 2021, at an academic medical center. A total of 102 participants were selected from a Class A tertiary hospital in Nanjing, China and randomized into three groups: finger exercise group (n = 34), acupoint massage group (n = 34), and handgrip exercise group (n = 34). Symptoms of edema and pain were defined as primary outcomes, while skin temperature and degree of bleeding as secondary outcomes, which were monitored and measured 1, 2, and 4 h, after the intervention.

Results

Among the 99 participants who completed the process, the palm edema was gradually relieved in the handgrip exercise group at 2 h (H = 6.710, P = 0.035) and 4 h (H = 10.060, P < 0.001) following the intervention. The edema of fingers in the handgrip exercise group was obviously relieved at 2 h (H = 9.353, P < 0.01) and 4 h (H = 10.699, P < 0.001) following the intervention compared with the other two groups. In addition, the pain score at 4 h (H = 7.048, P = 0.029) was clearly decreased in the handgrip exercise group. However, there was no significant difference in the punctured limb's skin temperature (H = 0.922, P = 0.631) and the degree of bleeding (H = 0.123, P = 0.940) among the three groups.

Conclusions

We found that handgrip exercise is more effective in reducing the edema of the limbs than finger exercise and acupoint massage.

Chronic scrotal pain: Pathogenesis, clinical phenotypes and modern treatment concept (clinical lecture)

Chronic scrotal pain (CSP) is a general term, which defines variety of problems causing discomfort or pain in the scrotum, which can be caused by the problems with testicles and other structures of the scrotum: epididymis, vas deferens, paratesticular structures. For a practicing urologist, the diagnosis and treatment of chronic scrotal pain is always a difficult task due to the many reasons for its appearance and the variety of clinical symptoms. CSP is a widespread but poorly understood condition, the etiology of which often can not be identified. Pain localized in the scrotum makes up 38.8 % of all cases of chronic men’s pelvic pain. From 2.5 to 4.8 % of all visits to the urologist relate to CSP syndrome. Primary scrotal pain syndrome is not associated with infection or other local pathological processes that could cause pain. The treatment of chronic scrotal pain is challenging because the pain often does not react to the traditional treatments.

The purpose of this lecture is to draw the attention of urologists, general practitioners, and everyone who is interested in the problem of treating chronic scrotal pain to the possibilities of modern medicine in solving this multidisciplinary problem.

International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study

BACKGROUND

Distal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.

OBJECTIVES

This study sought to comprehensively evaluate hand function in patients undergoing DRA.

METHODS

Real-world patients undergoing DRA undertook a thorough multimodality assessment of hand function implementing multidomain questionnaires (Disabilities of the Arm, Shoulder and Hand and Levine-Katz), and motor (pinch grip test) and sensory (Semmes-Weinstein monofilaments test) examinations of both hands. All assessments were performed at preprocedural baseline and planned at 1-, 6-, and 12-month follow-up (FU). Adverse clinical and procedural events were documented too.

RESULTS

Data of 313 patients (220 men, age 66 ± 10 years) from 9 international centers were analyzed. The Disabilities of the Arm, Shoulder and Hand and the Levine-Katz scores slightly improved from baseline to FU (P = 0.008 and P = 0.029, respectively). Pinch strength mildly improved from baseline to FU (P < 0.001 for both the left and right hands). Similarly, touch pressure threshold appeared to faintly improve in both the left and right hands (P < 0.012 for all the sites). For both motor and sensory function tests, comparable findings were found for the DRA hand and the contralateral one, with no significant differences between them. Repeated assessment of all tests over all FU time points similarly showed lack of worsening hand function. Access-related adverse events included 19 harmless bleedings and 3 forearm radial artery and 3 distal radial artery occlusions. None affected hand function at FU.

CONCLUSIONS

In a systematic multidimensional assessment, DRA was not associated with hand function impairment. Moreover, DRA emerges as a safe alternative vascular access.

Radial artery access for neuroendovascular procedures: safety review and complications

Although enthusiasm for transradial access for neurointerventional procedures has grown, a unique set of considerations bear emphasis to preserve safety and minimize complications. In the first part of this review series, we reviewed anatomical considerations for safe and easy neuroendovascular procedures from a transradial approach. In this second part of the review series, we aim to (1) summarize evidence for safety of the transradial approach, and (2) explain complications and their management.

The Impact of Using a Larger Forearm Artery for Percutaneous Coronary Interventions on Hand Strength: A Randomized Controlled Trial

(1) Background: The exact mechanism underlying hand strength reduction (HSR) after coronary angiography with transradial access (TRA) or transulnar access (TUA) remains unknown. (2) Methods: This study aimed to assess the impact of using a larger or smaller forearm artery access on the incidence of HSR at 30-day follow-up. This was a prospective randomized trial including patients referred for elective coronary angiography or percutaneous coronary intervention. Based on the pre-procedural ultrasound examination, the larger artery was identified. Patients were randomized to larger radial artery (RA) or ulnar artery (UA) or a group with smaller RA/UA. The primary endpoint was the incidence of HSR, while the secondary endpoint was the incidence of subjective HSR, paresthesia, and any hand pain. (3) Results: We enrolled 200 patients (107 men and 93 women; mean age 68 ± 8 years) between 2017 and 2018. Due to crossover between TRA and TUA, there were 57% (n = 115) patients in larger RA/UA and 43% (n = 85) patients in smaller RA/UA. HSR occurred in 29% (n = 33) patients in larger RA/UA and 47% (n = 40) patients in smaller RA/UA (p = 0.008). Subjective HSR was observed in 10% (n = 12) patients in larger RA/UA and 21% (n = 18) patients in smaller RA/UA (p = 0.03). Finally, paresthesia was noted in 7% (n = 8) patients in larger RA/UA and 22% (n = 15) in smaller RA/UA (p = 002). Independent factors of HSR were larger RA/UA (OR 0.45; 95% CI, 0.24-0.82; p < 0.01) and the use of TRA (OR 1.87; 95% CI, 1.01-34; p < 0.05). (4) Conclusions: The use of a larger artery as vascular access was associated with a lower incidence of HSR at 30-day follow-up.

Management of Chronic Orchialgia: Challenges and Solutions - The Current Standard of Care

INTRODUCTION

Chronic scrotal content pain (CSP) or chronic orchialgia can be debilitating for patients and difficult to treat. There is a paucity of structured treatment algorithms to approach this difficult condition.

METHODS

A review of the literature was performed. Conservative treatment options are presented and then targeted surgical interventions that the urologist may perform are then presented in a structured algorithm format. Many of these patients may obtain a significant reduction in pain with some of these treatments.

RESULTS

This review presents the pathophysiology, a new assessment tool, and various treatment options available for CSP patients, such as targeted spermatic cord blocks, targeted and standard microsurgical denervation of the spermatic cord (77-100% success rates), ultrasound-guided peri-spermatic cord and ilioinguinal cryoablation (59-75% success rates), scrotox (botox) (56-72% success rates), targeted ilioinguinal and iliohypogastric peripheral nerve stimulation (72% success rate), radical orchiectomy (20-75% success rate), targeted robotic-assisted intra-abdominal denervation (71% success rate) and vasectomy reversal (69-100% success rates).

CONCLUSION

A structured and evidence-based approach to help urologists manage patients with chronic orchialgia or scrotal content pain is presented.

Transradial Artery Access Complications

Transradial access (TRA) is favored over transfemoral access for performing coronary angiography and percutaneous coronary intervention due to the reduced risk for vascular and bleeding complications and the documented survival benefit in ST-segment–elevation myocardial infarction patients who undergo primary percutaneous coronary intervention. TRA complications can be categorized as intra- or postprocedural and further categorized as related to bleeding or nonbleeding issues. Major intra- and postprocedural complications such as radial artery perforation and compartment syndrome are rare following TRA. Their occurrence, however, can be associated with morbid consequences, including requirement for surgical intervention if not identified and treated promptly. Nonbleeding complications such as radial artery spasm and radial artery occlusion are typically less morbid but occur much more frequently. Strategies to prevent TRA complications are essential and include the use of contemporary access techniques that limit arterial injury. This document summarizes contemporary techniques to prevent, identify, and manage TRA complications.
