However, navigating thrombectomy devices in distal arteries remains challenging because of their small caliber and tortuous anatomy. This technical case report describes the initial clinical experience using the novel Passerelle 21 microcatheter, which features an extended effective length of 175 cm, to facilitate the safe and effective navigation of the Red 43 reperfusion catheter for DMVO thrombectomy in a primary distal M3 occlusion. An octogenarian woman presented 70 minutes after symptom onset with aphasia and right hemiparesis. Magnetic resonance imaging revealed no acute ischemic changes, whereas magnetic resonance angiography demonstrated an M3 occlusion in the left middle cerebral artery. Given her recent history of gastrointestinal bleeding, intravenous thrombolysis was withheld, and MT was performed. The Passerelle 21 microcatheter was coaxially advanced to guide the Red 43 catheter into the distal M3 segment, followed by aspiration thrombectomy with the Red 43 catheter using the ADAPT (A Direct Aspiration First Pass Technique) approach. This technique achieved Thrombolysis in Cerebral Infarction (TICI) grade 2c reperfusion in a single pass. The puncture-to-reperfusion time was 25 minutes, and the patient demonstrated significant neurological improvement postoperatively. This initial experience suggests that the Passerelle 21 microcatheter is a promising adjunctive device in DMVO treatment, with its extended length enabling stable distal navigation and optimized catheter positioning in complex vascular anatomy. Further clinical studies are warranted to evaluate its safety and efficacy in a broader patient population.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 7","pages":"Pages 3236-3242"},"PeriodicalIF":0.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While complications primarily involve flexor tendon irritation or rupture, extensor tendon injuries associated with volar plating are rare. This report discusses a 23-year-old male who experienced limited active range of motion (ROM) in the thumb and index finger of his right hand 2 years after volar plating for a distal radius fracture. Imaging studies, including radiography and MRI, confirmed satisfactory fracture healing. However, 2 screws were found protruding beyond the dorsal cortex of the distal radius. One screw extended over the Lister's tubercle, and another occupied the fourth compartment of the wrist. MRI also revealed the absence of the extensor indicis proprius (EIP) and extensor pollicis longus (EPL) tendons at the wrist level, suggesting tendon rupture. The plate and screws were removed via a palmar approach, and a 2-stage tendon graft procedure was performed to restore function. At the 1-year follow-up, the patient demonstrated excellent functional recovery, with no deficits in extending the thumb and index finger. This case highlights the risk of delayed multirupture of extensor tendons following volar plating of distal radius fractures, even after prolonged intervals postsurgery. Such complications, though rare, necessitate early recognition and management to prevent long-term functional impairments. Orthopedic and hand surgeons should consider this possibility during follow-ups and take preventive measures, such as ensuring screw lengths do not exceed the dorsal cortex during the initial procedure. By presenting this case, we aim to raise awareness of this potential complication and provide insights into its diagnosis, management, and prevention.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"20 7","pages":"Pages 3171-3178"},"PeriodicalIF":0.0,"publicationDate":"2025-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143820893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
