Acute sciatic nerve palsy secondary to postoperative seroma following soft tissue sarcoma resection: A case report.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction and importance: Seroma is a common complication following soft tissue sarcoma resection of lower extremity and might cause functional limitation, infection, prolonged postoperative course and delay in adjuvant treatment. This study aims to report on acute sciatic nerve palsy secondary to postoperative collection following soft tissue sarcoma resection. Case presentation: A 70-year-old male underwent radical re-resection of recurrent liposarcoma of right thigh with end-to-end anastomosis of femoral vein and artery. It was complicated by deep vein thrombosis and pulmonary embolism requiring therapeutic anticoagulation. On day 12 postoperatively, the patient developed seroma/hematoma compressing the sciatic nerve and resulting in complete paralysis and loss of sensation. An emergent incision and drainage with evacuation of the collection was performed. The patient regained near complete neurological function and was maintained on therapeutic anticoagulation. Clinical discussion: Seroma formation following STS resection results in a complex postoperative course with a prolonged hospital stay, functional limitations, wound complications and delayed adjuvant treatment. Acute sciatic nerve palsy secondary to compartment syndrome is a serious complication that can lead to worse outcomes requiring close follow-up and intervention. There is no consensus on the appropriate treatment and several options exist ranging from non-operative drain application and needle aspiration to surgical evacuation and debridement. Conclusion: Acute sciatic nerve palsy is a rare complication secondary to compression by seroma/hematoma following soft tissue sarcoma resection. The latter complication is reversible with adequate monitoring and prompt timely intervention especially in patients using potent anticoagulants.
