cilastatin--imipenem-drug-combination and Tendinopathy

To evaluate the feasibility and effects of transcatheter arterial embolization with imipenem/cilastatin sodium (CS) to treat tendinopathy and enthesopathy that are refractory to traditional nonsurgical management.. Transcatheter arterial embolization with imipenem/CS as an embolic agent was performed in seven patients (five men; mean age, 51.7 y) with tendinopathy and enthesopathy (patellar tendinopathy, n = 1; rotator cuff tendinopathy, n = 2; plantar fasciitis, n = 1; lateral epicondylitis, n = 1; iliotibial band syndrome, n = 1; and Achilles insertion tendinopathy, n = 1). All patients had unrelenting pain at the site of tendinopathy and enthesopathy before the procedure. Technical success, adverse events, and changes in visual analog scale (VAS) scores were assessed.. All procedures were technically successful, and no major adverse events developed. Compared with before the procedure, mean VAS scores were significantly decreased at 1 day, 1 week, and 1 and 4 months after the procedure (72.7 mm±9.9 vs 17.4 mm±18.5, 16.0 mm±18.1, 13.7 mm±7.3, and 9.7 mm±6.8, respectively; all P< .001).. Transcatheter arterial embolization with imipenem/CS was feasible and effectively relieved unrelenting pain associated with tendinopathy and enthesopathy.

To evaluate the effectiveness and safety of transcatheter arterial embolization to relieve pain associated with shoulder and elbow tendinopathy refractory to conservative treatment.. This study included 13 patients (15 cases) who underwent embolization between November 2015 and December 2016 to treat chronic shoulder pain (6 with rotator-cuff tendinopathy, 2 with calcific tendinitis) or elbow pain (7 with lateral epicondylitis) refractory to conservative treatment. Microspheres were used in the first 4 cases, and imipenem/cilastatin sodium was used in the remaining 11. Visual analog scale (VAS) score changes were recorded. Decrease in VAS score and degree of enhancement on digital subtraction angiography were compared.. The technical and clinical success rates were 100% (15/15) and 73% (11/15), respectively. The mean VAS scores at baseline, 1 day, 1 week, 1 month, and 4 months after embolization were 6.1, 5.8, 5.1, 4.3, and 2.5, respectively (P < .05 after 1 wk). Pain improved in 9 of 10 cases (90%) with "evident" enhancement and 3 of 5 cases (60%) with no evident enhancement. The VAS scores in the evident enhancement group decreased more than those in patients with no evident enhancement (4.5 vs 1.8; P < .05). Forearm cutaneous erythema was noted in 1 patient treated with microspheres.. Transcatheter arterial embolization may be an option for relieving pain associated with chronic shoulder and elbow tendinopathy refractory to conservative treatment. The degree of angiographic enhancement might be a possible factor affecting the degree of pain relief after embolization.
