Pneumothorax-II

Pneumothorax-II

Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Reoperation for recurrent spinal cord compression in metastatic cancer patients can preserve or improve function. This surgical option offers viable outcomes, including prolonged ambulation and good neurological status, in carefully selected cases.

Area of Science:

Neurosurgery
Oncology
Spinal Surgery

Background:

Metastatic spine disease often causes epidural spinal cord compression.
Recurrence of compression after initial surgery necessitates treatment evaluation.

Purpose of the Study:

To assess the outcomes of reoperation for recurrent epidural spinal cord compression in patients with metastatic spine disease.
To evaluate functional status, survival, and complications associated with repeat spinal surgery.

Main Methods:

Retrospective chart review of 39 patients undergoing reoperation for recurrent spinal cord compression at Memorial Sloan-Kettering Cancer Center (1996-2007).
Inclusion criteria: reoperation due to tumor recurrence causing high-grade compression or lack of radiation options. Exclusion criteria: reoperation solely for instrumentation failure.

Percutaneous Endoscopic Unilateral-Approach Bilateral Decompression for Lumbar Spinal Stenosis

Percutaneous Endoscopic Unilateral-Approach Bilateral Decompression for Lumbar Spinal Stenosis

Published on: February 9, 2024

All patients underwent decompression via a posterolateral approach without hardware removal.

Main Results:

Median survival was 12.4 months after the first reoperation and 9.1 months after the last.
65% of patients remained ambulatory at last follow-up or death.
97% of patients maintained or improved functional status by one Eastern Cooperative Oncology Group grade.
Major surgical complication rate was 5%.

Conclusions:

Reoperation is a viable strategy for recurrent high-grade epidural spinal cord compression in metastatic spine disease.
Carefully selected patients can achieve prolonged ambulation and favorable functional/neurological outcomes.
Repeat surgery at previously operated levels can be safe and effective.
