Results:
Of 1,832 catheter ablation procedures performed during a 5-year period, 10 (0.55%) were complicated by cardiac tamponade. Fluoroscopic examination confirmed the diagnosis in all 10 patients and demonstrated GANT61 inhibitor effusions before hypotension in four patients. All patients were stabilized by fluoroscopy-guided pericardiocentesis with placement of an indwelling catheter and autologous transfusion. The time interval between recognition of cardiac tamponade and completion of pericardiocentesis was 6.0 +/- 1.8 minutes (range 3-9 minutes). The mean aspirated blood volume was 437 mL (range 110-1,400 mL), and the mean autotransfused blood volume was 425 mL (range 100-1,384 mL). Surgical repair of the cardiac perforation was needed in one patient. No procedure-related death occurred.
Conclusion: A reduction in the excursion of cardiac silhouette on fluoroscopy is an early diagnostic sign of cardiac tamponade during radiofrequency ablation. Fluoroscopy-guided pericardiocentesis is a safe and effective management strategy for cardiac tamponade developed in the cardiac catheterization laboratory. (PACE 2011; 9-14).”
“Study Design. Case report.
Objective. To describe a patient with nodular fasciitis in the sciatic nerve, detected Natural Product Library mw by positron emission tomography (PET).
Summary of Background Data. Severe sciatic
pain is commonly caused by lumbar disc herniation, lumbar spinal stenosis, or neoplastic lesion.
These lesions are usually diagnosed by plain radiograph, myelography, computed tomography, and magnetic resonance imaging.
Nodular fasciitis is a benign connective tissue tumor usually presenting as a firm, rapidly-growing lesion, occasionally arising in the forearm. Only 5 cases of intraneural nodular fasciitis have been reported in the published data, and although some have demonstrated mild neuropathy, none have shown nodular fasciitis with intractable sciatica.
Methods. A 37-year old woman experienced severe sciatica after hitting her left buttock hard on the edge of a bathtub. Physical examination demonstrated intense radiating pain from the left buttock to the lateral calf. There was weakness in the sciatic nerve innervated musculature. JPH203 She was diagnosed with piriformis syndrome in a local hospital. However, the symptoms remained unchanged after surgery, releasing the piriformis. Conventional imaging of the sciatica including plain radiograph, computed tomography, and magnetic resonance imaging of the spine showed a return of abnormal findings.
Results. PET detected an abnormal lesion in the sciatic nerve in the posterior compartment of the patient’s left thigh, indicating an intraneural tumor in the sciatic nerve. Subtotal resection was achieved and histologic evaluation of the specimen showed the typical features of nodular fasciitis.
