ObjectiveTo summarize the experience and lessons of right ventricular decompression in children with pulmonary atresia and intact ventricular septum (PA/IVS) and to reflect on the strategies of right ventricular decompression.MethodsThe clinical data of 12 children with PA/IVS who underwent right ventricular decompression in our hospital from March 2015 to December 2019 were reviewed retrospectively. There were 10 males and 2 females with a median age at the time of surgery was 5 d (range, 1-627 d). Correlation analysis between the pulmonary valve transvalvular pressure gradient and changes in Z score of tricuspid valves after decompression was performed.ResultsOne patient died of refractory hypoxemia due to circulatory shunt postoperatively and family members gave up treatment. There were 2 (16.67%) patients received postoperative intervention. The pulmonary transvalvular gradient after decompression was 31.95±21.75 mm Hg. Mild pulmonary regurgitation was found in 7 patients, moderate in 2 patients, and massive in 1 patient. The median time of mechanical ventilation was 30.50 h (range, 6.00-270.50 h), and the average duration of ICU stay was 164.06±87.74 h. The average postoperative follow-up time was 354.82±331.37 d. At the last follow-up, the average Z score of tricuspid valves was 1.32±0.71, the median pressure gradient between right ventricle and main pulmonary artery was 41.75 mm Hg (range, 21-146 mm Hg) and the average percutaneous oxygen saturation was 92.78%±3.73%. Two children underwent percutaneous balloon pulmonary valvoplasty at 6 and 10 months after surgery, respectively, with the rate of reintervention-free of 81.8%. There was no significant correlation between pulmonary transvalvular gradients after decompression and changes in Z score of tricuspid valves (r=–0.506, P=0.201).ConclusionFor children with PA/IVS, the simple pursuit of adequate decompression during right ventricular decompression may lead to severe pulmonary dysfunction, increase the risk of ineffective circular shunt, and induce refractory hypoxemia. The staged decompression can ensure the safety and effectiveness for initial surgery and reduce the risk of postoperative death.
Objective To investigate the therapeutic effect of long PHILOS locking compression plate on the proximal humerus and humeral shaft fractures. Methods From March 2005 to December 2007, 35 cases with the proximal humerus and humeral shaft fractures were treated with long PHILOS locking compression plate, including 16 males and 19 females aged 29-68 years old (average 54.5 years old). There were 34 cases of fresh and close fracture, and the time from injury to operation was 3-9 days. One case had delayed union of fracture 5 months after receiving T-plates and internal fixation with steel plate. For the proximal humerus fracture, 7 cases had 2 parts of fracture, 19 had 3 parts of fracture, and 9 had 4 parts of fracture according to Neer classification; while for the humeral shaft fracture, 3 cases were classified as A1, 5 as A2, 10 as B1, 3 as B2, 6 as B3, 7 as C1 and 1 as C3 according to AO classification. Postoperatively, Neer scoring system was employed to evaluate the function of shoulder joint and HSS scoring system was adopted to evaluate the function of elbow joint. Results All incisions healed by first intension, and 30 cases were followed up for 12-33 months (average 18.2 months). Postoperatively, 2 cases had symptoms of radial nerve paralysis, which disappeared within 3 weeks; 1 case suffered from humeral head necrosis and received the secondary operation of humeral head replacement; humeral head was reduced evenly in 1 case, and 2 cases felt chronic sl ight pain in shoulder joints and received no further treatment. X-ray films showed 29 cases had fracture heal ing 6 months after operation, and all the patients had bone union 12 months after operation except 1 case receiving humeral head replacement. No such compl ications as screw lossening and internal fixation loosening occurred. By Neer scoring system, 6 cases were graded as excellent, 19 as good, 3 as fair, 2 as poor, and the excellent and good rate was 83.3%. By HSS scoring system, 16 cases were gradedas excellent, 14 as good, and the excellent and good rate was 100%. Conclusion Applying long PHILOS locking compression plate in the treatment of the proximal humerus and humeral shaft fractures provides a sol id fixation and high satisfactory rate with minor compl ications.
ObjectiveTo investigate the feasibility of thoracolapascopic esophagectomy (TLE) without routine nasogastric (NG) intubation for patients with esophageal cancer (EC).
MethodsClinical data of 78 EC patients under-going TLE without perioperative NG intubation in Affiliated Cancer Hospital of Zhengzhou University from January to September 2013 were analyzed (non-NG intubation group, including 48 male and 30 female patients with their age of 61.1± 8.5 years). Seventy-eight EC patients undergoing TLE with routine NG intubation for 7 days in 2012 were chosen as the control group (NG intubation group, including 50 male and 28 female patients with their age of 60.3±7.0 years). Operation time, postoperative morbidity, gastrointestinal functional recovery and patient discomfort were compared between the 2 groups.
ResultsThere was no in-hospital death in either groups. There was no statistic difference in the incidences of pulmonary infection (16.7% vs. 19.2%, P=0.676), anastomotic leakage (1.3% vs. 2.6%, P=0.560) or NG tube replacement (3.8% vs. 2.6%, P=0.649) between non-NG intubation group and NG intubation group. Time for recovery of intestinal motility (2.5± 1.1 days vs. 4.3±1.2 days, P < 0.05) and time for air evacuation (3.6±1.7 days vs. 5.8±2.1 days, P < 0.05) of non-NG intubation group were significantly shorter than those of NG intubation group. Ninety-seven percent of the patients (76/78)in NG intubation group had uncomfortable feeling including dry mouth and sore throat, and only 6% of the patients (5/78) in non-NG intubation group had nausea. All the patients were followed up for 3 months after discharge. There was no intestinal obstruction, pneumonia or late anastomotic leakage during follow-up.
ConclusionTLE without routine NG intubation is safe and feasible for EC patients, which can not only reduce patients' discomfort but also improve early recovery of gastrointestinal function.
Although extracorporeal membrane oxygenation (ECMO) has been in existence since the 1970s as a means of supporting respiratory or cardiac function, early application of this technology was plagued by high complication rates. Peripheral veno-arterial extracorporeal membrane oxygenation (V-A ECMO) causes higher left ventricular end-diastolic pressure, pulmonary edema, left ventricular distention, ventricular arrhythmia, low coronary perfusion, myocardial ischemia, substantial thrombus formation within left ventricule cavity and even multiple organ dysfunction. Mechanical left ventricular decompression is required to treat these related complications. In this article, we reviewed the problems associated with left ventricular decompression supported by peripheral V-A ECMO in patients with cardiogenic shock.
Objective To design the surgical strategy of percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for bilateral lumbar spinal stenosis (LSS) and to evaluate the effectiveness. Methods The percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for bilateral LSS was designed according to the pathological features of LSS. The technique was used to treat 42 patients with LSS between January 2016 and January 2018. There were 18 males and 24 females with an average age of 61.7 years (range, 46-81 years). The duration of symptoms was 1-20 years, with an average of 9.7 years. The surgical segment at L4, 5 were 27 cases, at L5, S1 were 15 cases. The operation time and perioperative complications were recorded. Lumbar X-ray, CT, and MRI examinations were performed at 1 week, 3 months, and 1 year after operation. Visual analogue scale (VAS) score was used to evaluate the low back pain and leg pain, Oswestry disability index (ODI) was used to evaluate the lumbar function, and single continuous walking distance (SCWD) was used to evaluate lower extremity nerve function. The clinical efficacy was evaluated by MacNab criteria at 1 year after operation. Results All patients underwent surgery successfully. The operation time was 68-141 minutes with an average of 98.2 minutes. All 42 patients were followed up 12-24 months with an average of 18.8 months. There were 2 cases of dural tears during operation, and 1 case of transient dysfunction of the lower limbs of the decompression channel after operation. All of them were cured after corresponding treatment. No serious complications such as death, major bleeding, or irreversible nerve injury occurred during follow-up. No segmental instability was found according to postoperative lumbar hyperextension and flexion X-ray films, and postoperative CT and MRI imaging showed that the stenotic lumbar spinal canal was significantly enlarged, and the compression of the nerve root was sufficient. The VAS score of low back pain and leg pain, ODI score, and SCWD at each time point after operation were significantly improved when compared with those before operation (P<0.05); the indexes were significantly improved over time after operation, and the differences were significantly (P<0.05). The clinical efficacy was evaluated by MacNab standard at 1 year after operation, and the results were excellent in 18 cases, good in 20 cases, fair in 3 cases, and poor in 1 case. The excellent and good rate was 90.5%. Conclusion The percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for LSS is a safe and effective procedure. A well-designed surgical strategy and mastery of its technical points are important guarantees for successful operation and satisfactory results.
ObjectiveTo investigate the effectiveness of sagittal top compression reduction technique in the treatment of thoracolumbar vertebral fractures. Methods A retrospective analysis was conducted on the clinical data of 59 patients with thoracolumbar vertebral fractures who met the selection criteria and were admitted between November 2018 and January 2022. Among them, 34 patients were treated with sagittal top compression reduction technique (top pressure group), and 25 patients were treated with traditional reduction technique (traditional group). There was no significant difference in baseline data between the two groups (P>0.05), including gender, age, fracture segment, cause of injury, AO classification of thoracolumbar vertebral fractures, thoracolumbar injury classification and severity (TLICS) score, American Spinal Injury Association (ASIA) grading, surgical approach, preoperative vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, segmental kyphosis angle, visual analogue scale (VAS) score, and Oswestry disability index (ODI). The operation time, intraoperative blood loss, and incidence of complications between the two groups were recorded and compared. After operation, VAS score and ODI were used to evaluate effectiveness, and X-ray and CT examinations were performed to measure imaging indicators such as vertebral body index, height ratio of the anterior margin of injured vertebra, injured vertebra angle, and segmental kyphosis angle. ResultsThere was no significant difference in operation time and intraoperative blood loss between the two groups (P>0.05). No complication such as dural sac, nerve root, or vascular injury was found during operation, and all incisions healed by first intention. Patients in both groups were followed up 6-48 months, with an average of 20.6 months. No loosening, breakage, or failure of internal fixation occurred during follow-up. The imaging indicators, VAS score, and ODI of the two groups significantly improved at 1 week and last follow-up when compared to preoperative ones (P<0.05). At last follow-up, the VAS score and ODI further significantly improved when compared to 1 week after operation (P<0.05). At 1 week after operation and last follow-up, the vertebral body index, segmental kyphosis angle, injured vertebra angle, and ODI in the top pressure group were significantly better than those in the traditional group (P<0.05). There was no significant difference in VAS score and height ratio of the anterior margin of injured vertebra between the two groups at 1 week after operation (P>0.05), but the two indicators in the top pressure group were significantly better than those in the traditional group at last follow-up (P<0.05). Conclusion The treatment of thoracolumbar vertebral fractures with sagittal top compression reduction technique can significantly improve the quality of vertebral reduction, and is superior to traditional reduction techniques in relieving pain and improving spinal function.
ObjectiveTo review the current progress of treatment of cubital tunnel syndrome (CTS).
MethodsRecent relevant literature on the treatment of CTS was extensively reviewed and summarized.
ResultsCTS is one of the most common peripheral nerve compression diseases.The clinical presentations of CTS consist of numbness and tingling in the ring and small fingers of the hand,pain in the elbow and sensory change following long-time elbow bending.Severe symptoms such as weakness or atrophy of intrinsic muscles of the hand and claw hand deformity may occur.The etiology of CTS is ulnar nerve compression caused by morphological abnormalities and nerve paralysis after elbow trauma.CTS can be treated by nonsurgical methods and surgery.Surgical options include in situ decompression,ulnar nerve transposition,medial epicondylectomy,and endoscopic release.
ConclusionThere are multiple options to treat CTS,but the indication and effectiveness of each treatment are still controversial.Further studies are required to form a generally accepted treatment system.
The surgical treatment of pectus excavatum has a history of more than 100 years, which has gone through from traditional open surgery to the current popular minimally invasive surgery. Nuss procedure, as the most classic minimally invasive operation, has been improved in accordance with the clinical needs since its inception to achieve fewer complications and better results, but there are still limitations that are difficult to break through, attracting a large number of scholars to make continuous innovation and develop updated devices and operation methods. This article reviews the history of funnel chest surgery, application and improvement of Nuss operation, double compression and complete fixation bar system and Wang procedure.
ObjectiveTo evaluate the efficacy and safety of intracavitary treatment for iliac vein compression syndrome（IVCS）with acute lower extremity deep venous thrombosis (DVT).MethodsThe clinical data of 57 patients with IVCS and lower extremity DVT, who undergoing with stent implantation, balloon expansion and Angiojet rheolytic thrombectomy from June 2015 to June 2018, were retrospectively analyzed. The effect of treatment was evaluated by the changes of thigh circumference difference between the affected side and the healthy side, and the thrombosis clearance rate in the operating. In addition, the incidence of post-thrombotic syndrome (PTS) and stent patency rate were analyzed after long-term follow-up based on the change of Villaita scale score and ultrasound examination of lower extremity veins.ResultsThe success rate of surgical technique was 100%, and there was no pulmonary embolism during operating and postoperative. Lower extremity deep vein thrombosis clearance levels Ⅲ 48 cases (84.2%), Ⅱ 9 cases (15.8%), the changes of thigh circumference difference between the affected side and the healthy side from preoperative (5.8±1.7) cm to (3.7±1.0) cm. One year follow-up after operation, the primary patency rate of stent was 86.0% and PTS occurred in 8 patients (14.0%).ConclusionStent implantation, balloon expansion and Angiojet rheolytic thrombectomy for IVCS with acute lower extremity DVT is a safe, effective with low incidence of complications and efficient thrombus clearance.
ObjectiveTo evaluate the effectiveness of Curved Diffusion Needle in unilateral percutaneous vertebroplasty (PVP) by compared with bilateral PVP. MethodsA clinical data of 93 patients with osteoporotic vertebral compression fracture (OVCF) treated with PVP between January 2020 and January 2021 was retrospectively analyzed, including 47 patients underwent unilateral PVP assisted with Curved Diffusion Needle (unilateral group) and 46 patients underwent bilateral PVP (bilateral group). There was no significant difference in gender, age, cause of injury, time from injury to operation, T value of bone mineral density, AO classification, distribution of injured vertebrae, and preoperative visual analogue scale (VAS) score, Oswestry disability index (ODI), relative height of injured vertebrae, and Cobb angle between the two groups (P>0.05). The operation time, the amount of bone cement injection, the incidence of bone cement leakage, the bone cement diffusion distribution, VAS score, ODI, the relative height of injured vertebrae, and Cobb angle were recorded and compared between the two groups. Results All operations successfully completed. The operation time was significantly shorter in unilateral group than in bilateral group (t=?13.936, P=0.000), and the amount of bone cement injection was significantly less in unilateral group than in bilateral group (t=?13.237, P=0.000). The incidence of bone cement leakage in unilateral group was 19.14%, which was significantly lower than that in bilateral group (39.13%) (χ2=4.505, P=0.034). The score of bone cement distribution in unilateral group was 7.0±1.3, of which 41 cases were excellent and 6 cases were well. The score of bilateral group was 7.4±0.8, of which 43 cases were excellent and 3 cases were well. There was no significant difference in score and grading of bone cement distribution between the two groups (t=?1.630, P=0.107; Z=?1.013, P=0.311). All patients were followed up and the follow-up time was 3-10 months (mean, 6.5 months) in unilateral group and 3-10 months (mean, 6.1 months) in bilateral group. The VAS score, ODI, the relative height of injured vertebrae, and Cobb angle at 24 hours after operation and last follow-up were significantly better than those before operation in the two groups (P<0.05). There were significant differences in all indicators between 24 hours after operation and last follow-up (P<0.05). There was no significant difference in all indexes between the two groups (P>0.05) at the same time point after operation. During follow-up, there was no complication such as contralateral vertebral collapse, refracture, adjacent vertebral fracture, or local kyphosis in the two groups. ConclusionUnilateral PVP assisted with Curved Diffusion Needle for OVCF is beneficial to the distribution of bone cement, which can not only achieve similar effectiveness to bilateral PVP, but also achieve shorter operation time, less bone cement injection, and lower risk of bone cement leakage.
