Radial Artery Pseudoaneurysms Treated by Ultrasound-Guided Differential Compression: An Effective and Simple Method.

ABSTRACT: Transradial approach has become preferable to conventional femoral artery access for both diagnostic coronary angiography and percutaneous coronary intervention. A rare but recognizable complication of radial access is radial artery pseudoaneurysm (RAp), which represents a potentially catastrophic complication. Treatment options comprise ultrasound (USG)-guided manual compression or thrombin injection or surgical correction. In this case series, we report four cases of RAps that we encountered at a single tertiary care center from July 2015 to January 2018. We compressed the radial artery using a sphygmomanometer cuff differentially rather than a TR band proximal to the pseudoaneurysm to treat three of them. One of the patients underwent surgical repair of the pseudoaneurysm as the location of the aneurysm was not suitable for compression or thrombin injection. In our series of cases, we conclude that RAp, a rare complication of radial catheterization, was seen more commonly in elderly female patients and can be easily treated by the USG-guided differential compression, a simple and readily available method. Prevention and early diagnosis is the key to avoid serious consequences.

Project description:BackgroundPeripheral pulmonary lesion (PPL) incidence is rising because of increased chest imaging sensitivity and frequency. For PPLs suspicious for lung cancer, current clinical guidelines recommend tissue diagnosis. Radial endobronchial ultrasound (R-EBUS) is a bronchoscopic technique used for this purpose. It has been observed that diagnostic yield is impacted by the ability to accurately manipulate the radial probe. However, such skills can be acquired, in part, from simulation training. Three-dimensional (3D) printing has been used to produce training simulators for standard bronchoscopy but has not been specifically used to develop similar tools for R-EBUS.ObjectiveWe report the development of a novel ultrasound-compatible, anatomically accurate 3D-printed R-EBUS simulator and evaluation of its utility as a training tool.MethodsComputed tomography images were used to develop 3D-printed airway models with ultrasound-compatible PPLs of "low" and "high" technical difficulty. Twenty-one participants were allocated to two groups matched for prior R-EBUS experience. The intervention group received 15 minutes to pretrain R-EBUS using a 3D-printed model, whereas the nonintervention group did not. Both groups then performed R-EBUS on 3D-printed models and were evaluated using a specifically developed assessment tool.ResultsFor the "low-difficulty" model, the intervention group achieved a higher score (21.5 ± 2.02) than the nonintervention group (17.1 ± 5.7), reflecting 26% improvement in performance (P = 0.03). For the "high-difficulty" model, the intervention group scored 20.2 ± 4.21 versus 13.3 ± 7.36, corresponding to 52% improvement in performance (P = 0.02). Participants derived benefit from pretraining with the 3D-printed model, regardless of prior experience level.Conclusion3D-printing can be used to develop simulators for R-EBUS education. Training using these models significantly improves procedural performance and is effective in both novice and experienced trainees.
