Endoscopic-Assisted Transaxillary Approach for First Rib Resection in Thoracic Outlet Syndrome.

ABSTRACT:

Purpose

To assess the feasibility, safety, and clinical outcomes of an endoscopic-assisted transaxillary approach of first rib resection for thoracic outlet syndrome (TOS) and to compare the differences in demographic and clinical data between satisfactory and unsatisfactory outcomes using this approach.

Methods

We retrospectively identified patients who underwent endoscopic-assisted first rib partial resection. A transaxillary approach for the first rib resection and neurovascular decompression were undertaken under magnified visualization. Endoscopic classification of neurovascular bundle (NVB) patterns and interscalene distance (ISD) between anterior and middle scalene muscles were evaluated intraoperatively. We assessed the Roos and DASH scores.

Results

We reviewed 131 cases of TOS (48 women and 83 men; mean age 26.2 years; range 12 to 57). Roos classification revealed 80.2% excellent or good results. DASH scores improved significantly from 40.7 ± 20.0 to 15.7 ± 19.6 (P < .001). The complication rate was low (5.3%), with 4 pneumothorax and 3 other complications. Intraoperative NVB classification revealed 30 cases of parallel type, in which the artery and nerve travel in parallel; 69 oblique types, and 30 vertical types, in which the nerve was completely behind the middle scalene muscle or abnormal band. The ISD was narrower (5.4 ± 3.6 mm) than in previous cadaveric studies. The ISD in the parallel patterns was wider than that in the vertical patterns. In the satisfactory group, we found a significantly larger number of men, younger patients, athletes, and patients with a lower preoperative DASH score.

Conclusions

An endoscopic-assisted transaxillary approach for first rib resection in TOS provides an excellent magnified visualization, safely allowing sufficient decompression of the neurovascular bundle and satisfactory surgical outcomes. Younger male athletes with TOS may be better candidates for this procedure.

Project description:Objectives: The treatment for neurogenic thoracic outlet syndrome (NTOS) conventionally involves first-rib resection (FRR) surgery, which is quite challenging to perform, especially for novices, and is often associated with postoperative complications. Herein, we report a new segmental resection approach through piezo surgery that involves using a bone cutter, which can uniquely provide a soft tissue protective effect. Methods: This retrospective study involved the examination of 26 NTOS patients who underwent piezo surgery and another group of 30 patients who underwent FRR using the conventional technique. In the patient group that underwent piezo surgery, the rib was first resected into two pieces using a piezoelectric device and subsequently removed. In the patient group that underwent conventional surgery, the first rib was removed as one piece using a rib cutter and rongeurs. Results: The piezo surgery group had significantly shorter operative time (96.85 ± 14.66 vs. 143.33 ± 25.64 min, P < 0.001) and FRR duration (8.73 ± 2.11 vs. 22.23 ± 6.27 min, P < 0.001) than the conventional group. The posterior stump length of the residual rib was shorter in the piezo surgery group than in the conventional group (0.54 ± 0.19 vs. 0.65 ± 0.15 cm, P < 0.05). There were no significant differences in postoperative complications and scores of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, the Cervical Brachial Symptom Questionnaire (CBSQ), and the visual analog scale (VAS). Even the TOS index (NTOS Index = [DASH + (0.83 × CBSQ) + (10 × VAS)]/3) and patient self-assessments of both the groups showed no significant differences. Univariate analyses indicated that the type of treatment affected operative time. Conclusion: Our results suggest that piezo surgery is safe, effective, and simple for segmental FRR in NTOS patients. Piezo surgery provides a more thorough FRR without damaging adjacent soft tissues in a relatively short duration and achieves similar functional recovery as conventional techniques. Therefore, piezo surgery can be a promising alternative for FRR during the surgical treatment of NTOS.

Project description:UNLABELLED: The authors' experience with the supraclavicular approach for the treatment of patients with primary thoracic outlet syndrome (TOS) and for patients with recurrent TOS or iatrogenic brachial plexus injury after prior transaxillary first rib resection is presented. The records of 33 patients (34 plexuses) with TOS who presented for evaluation and treatment were analyzed. Of these, 12 (35%) plexuses underwent surgical treatment, and 22 (65%) plexuses were managed non-operatively. The patients who were treated non-operatively and had an adequate follow-up (n?=?11) were used as a control group. Of the 12 surgically treated patients, five patients underwent primary surgery; four patients had secondary surgery for recurrent TOS; and three patients had surgery for iatrogenic brachial plexus injury. All patients presented with severe pain, and most of them had neurologic symptoms. All nine (100%) patients who underwent primary surgery (n?=?5) and secondary surgery for recurrent TOS (n?=?4) demonstrated excellent or good results. On the other hand, six (54%) of the 11 patients from the control group had some benefit from the non-operative treatment. Reoperation in three patients with iatrogenic brachial plexus injury resulted in good result in one case and in fair results in two patients; however, all patients were pain-free. No complications were encountered. Supraclavicular exploration of the brachial plexus enables precise assessment of the contents of the thoracic inlet area. It allows for safe identification and release of all abnormal anatomical structures and complete first rib resection with minimal risk to neurovascular structures. Additionally, this approach allows for the appropriate nerve reconstruction in cases of prior transaxillary iatrogenic plexus injury.
