The use of neoadjuvant lobar radioembolization prior to major hepatic resection for malignancy results in a low rate of post hepatectomy liver failure

BackgroundNeoadjuvant yttrium-90 transarterial radioembolization (TARE) is increasingly being used as a strategy to facilitate resection of otherwise unresectable tumors due to its ability to generate both tumor response and remnant liver hypertrophy. Perioperative outcomes after the use of neoadjuvant lobar TARE remain underinvestigated.MethodsA single center retrospective review of patients who underwent lobar TARE prior to major hepatectomy for primary or metastatic liver cancer between 2007 and 2018 was conducted. Baseline demographics, radioembolization parameters, pre- and post-radioembolization volumetrics, intra-operative surgical data, adverse events, and post-operative outcomes were analyzed.ResultsTwenty-six patients underwent major hepatectomy after neoadjuvant lobar TARE. The mean age was 58.3 years (17–88 years). 62% of patients (n=16) had primary liver malignancies while the remainder had metastatic disease. Liver resection included right hepatectomy or trisegmentectomy, left or extended left hepatectomy, and sectorectomy/segmentectomy in 77% (n=20), 8% (n=2), and 15% (n=4) of patients, respectively. The mean length of stay was 8.3 days (range, 3–33 days) and there were no grade IV morbidities or 90-day mortalities. The incidence of post hepatectomy liver failure (PHLF) was 3.8% (n=1). The median time to progression after resection was 4.5 months (range, 3.3–10 months). Twenty-three percent (n=6) of patients had no recurrence. The median survival was 28.9 months (range, 16.9–46.8 months) from major hepatectomy and 37.6 months (range, 25.2–53.1 months) from TARE.ConclusionsMajor hepatectomy after neoadjuvant lobar radioembolization is safe with a low incidence of PHLF.     

Management of spine fractures C3 to C7

The goals of management of spine fractures from C3 to C7 are to provide stability for maximum pain-free function and to prevent further or future injury to the spinal cord and nerve roots. Surgical fusion may be necessary to provide immediate and long-term stability. Posterior instability should be treated by posterior fusion, and anterior instability should be treated with anterior stabilization.     

Neurologic injury and recovery patterns in burst fractures at the T12 or L1 motion segment

Fourteen consecutive patients with burst fractures at T12 or L1, partial paralysis, and more than 30% canal compromise were prospectively evaluated pretreatment and posttreatment with roentgenograms to determine the initial fracture pattern, CT scans to determine the percent canal compromise and subsequent improvement, and a quantitative motor trauma index scale and bladder sphincter evaluation to determine neurologic recovery. The follow-up period averaged 32 months (range, 12-50 months). Treatment was as follows: nonoperative (three patients), Harrington rods and fusion (seven patients), and Harrington rods and fusion followed by anterior decompression and fusion (four patients). The initial severity of paralysis did not correlate with the initial fracture roentgenographic pattern or the amount of initial CT canal compromise. Neurologic recovery did not correlate with the treatment method or amount of canal decompression. Subsequent recovery did correlate with the initial fracture pattern. If the patient had a Type I or Type II fracture (both greater than 15 degrees kyphosis), greater than 90% neurologic recovery occurred, regardless of treatment. If the patient had a Type III fracture (less than 15 degrees kyphosis and the maximal canal compromise where bone encircles the canal) less than 50% neurologic recovery occurred. If the patient had a Type IV fracture (less than or equal to 15 degrees kyphosis and the maximal canal compromise at the level of the ligamentum flavum), the neurologic recovery was variable. Prognosis for neurologic recovery can be made based on initial roentgenograms. If greater than 15 degrees kyphosis is present, there is a good prognosis.(ABSTRACT TRUNCATED AT 250 WORDS)
