  • Comparative analysis of unilateral biportal endoscopic discectomy, percutaneous endoscopic lumbar discectomy, and fenestration discectomy in treatment of lumbar disc herniation

    Objective To investigate the effectiveness of unilateral biportal endoscopic discectomy (UBED), percutaneous endoscopic lumbar discectomy (PELD), and traditional fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). Methods The clinical data of 347 LDH patients who met the selection criteria and underwent discectomy between January 2017 and December 2021 were retrospectively analyzed. They were divided into FD group (160 cases), PELD group (86 cases), and UBED group (101 cases) according to operation methods. There was no significant difference in gender, age, surgical level distribution, disease duration, and preoperative visual analogue scale (VAS) score and Oswestry disability index (ODI) between groups (P>0.05). The operation time, hospitalization stay, treatment cost, and incidence of surgery-related complications were recorded and compared between groups. The patients’ pain and functional recovery were evaluated by VAS score and ODI before and after operation. Results The operation time of FD group was significantly shorter than that of PELD group and UBED group, and the hospitalization stay was significantly longer than that of PELD group and UBED group (P<0.05); there was no significant difference between PELD group and UBED group (P>0.05). The treatment cost in UBED group was significantly higher than that in PELD group, and in PELD group than in FD group (P<0.05). All the patients were followed up 6-24 months, with an average of 14.6 months. VAS score of lower extremity and ODI in 3 groups significantly improved after operation when compared with that before operation (P<0.05). At 1 day after operation, VAS score of lower extremity of UBED group was significantly better than that in PELD group and FD group (P<0.05), but there was no significant difference between PELD group and FD group (P>0.05). There was no significant difference in VAS scores of lower extremity between the 3 groups at 1 and 3 months after operation (P>0.05). The difference of ODI before and after operation in FD group and UBED group was slightly better than that in PELD group (P<0.05), and there was no significant difference between FD group and UBED group (P>0.05). Incidence of surgery-related complications in FD group (20.0%) was significantly higher than that in PELD group (12.8%) and UBED group (6.9%), and PELD group was significantly higher than UBED group (P<0.05). All the incision infection occurred in FD group (12 cases), symptomatic disc cyst and myeloid hypertension-like occurred in 1 case each in PELD group.Conclusion UBED, PELD, and FD have similar effectiveness on lower extremity pain in early LDH. Compared with FD, UBED and PELD have the advantage of shorter hospitalization stay and fewer complications.

  • Impact of Obesity on Postoperative Morbidity after Pneumonectomy

    Abstract: Objective To explore the impact of obesity on postoperative morbidity and mortality after pneumonectomy. Methods Clinical data of 3 494 patients with pulmonary diseases who underwent pneumonectomy in Shanghai Pulmonary Hospital from September 2003 to December 2007 were retrospectively analyzed. All the 3 494 patients were divided into two groups according to the patients’ preoperative body mass index (BMI). There were 3 340 patients in the non-obesity group (BMI<28 kg/m2) including 2 502 males and 838 females with their average age of 61.9±10.7 years, and 154 patients in the obesity group (BMI≥28 kg/m2) including 87 males and 67 females with their average age of 59.7±9.6 years. Univariate analysis and logistic regression were used to analyze the impact of obesity (BMI≥28 kg/m2) on postoperative morbidity after pneumonectomy. Results There were a total of 26 cases of perioperative death, including 23 patients in the non-obesity group and 3 patients in the obesity group. There was no statistical difference in mortality between the two groups [0.7% (23/3 340) vs. 1.9% (3/154), P=0.118]. There was no statistical difference in any particular postoperative morbidity or incidence of pulmonary complications between the two groups (P>0.05). Other than pulmonary complications, the incidence of postoperative complication in other body systems of the obesity group was significant higher than that of the non-obesity group (P<0.05). The incidence of cerebrovascular accidents, myocardial infarction and acute renal failure of the obesity group was significant higher than those of the non-obesity group (P<0.05). Logistic regression showed that obesity (BMI≥28 kg/m2) was not an independent risk factor for postoperative morbidity after pneumonectomy [B=0.648, OR=1.911, 95% CI(0.711, 5.138),P=0.199]. Conclusion Obesity is not a significant risk factor of postoperative mortality or morbidity after pneumonectomy.

  • Clinical application of perforator-based propeller flaps in repair of hand wound

    Objective To investigate the effectiveness of the perforator-based propeller flaps (PPFs) based on digital artery (DA) and dorsal metacarpal artery (DMA) in repairing hand wounds. Methods The clinical data of 45 patients with hand wounds between January 2018 and March 2023 were retrospectively analyzed. There were 27 males and 18 females with an average age of 41.2 years (range, 14-72 years). The causes of injury included twist injury in 15 cases, crush injury in 19 cases, and cut injury in 11 cases. The injured parts included 32 cases of digits, 10 cases of dorsal hand, and 3 cases of palmar hand, all of which had tendon, joint, and bone exposure. The time from injury to operation ranged from 2 to 8 hours (mean, 4.3 hours). The wound sizes after debridement ranged from 1.8 cm×1.0 cm to 5.0 cm×3.5 cm. Twenty-eight cases were repaired by the PPFs based on DA and 17 cases were repaired by the PPFs based on DMA. The flap size ranged from 2.5 cm×1.1 cm to 8.5 cm×4.0 cm. The defects of the donor sites in 14 patients were closed directly and the defects in the left 31 patients were resurfaced with free full-thickness skin graft from the proximal medial forearm.Results All the flaps survived after operation. Two cases of the PPF based on DA and 1 case of the PPF based on DMA underwent partially blisters at the distal end and healed after dressing change. The incisions in the donor site healed by first intention and the skin grafts survived. All patients were followed up 10-33 months, with a mean of 15.4 months. At last follow-up, the static two-point discrimination of the PPFs based on DA and DMA were 4-14 mm and 8-20 mm with the averages of 8.1 mm and 13.3 mm, respectively. According to the Michigan Hand Outcomes Questionnaire, 20 patients were very satisfied with the appearance of the PPF based on DA and 8 patients were satisfied; 8 patients were very satisfied with the appearance of the PPF based on DMA and 9 patients were satisfied. Based on the Vancouver Scar Scale (VSS), the appearance scores of the donor site of the PPFs based on DA and DMA were 2-7 and 4-9, with the averages of 4.2 and 6.1, respectively. ConclusionThe two kinds of PPFs are reliable in blood supply and easy to harvest, which provide a good method for emergency repair of small and medium area wounds in the hand.

  • Efficacy and safety of ultrasound-guided percutaneous retrograde closure of patent ductus arteriosus

    ObjectiveTo evaluate the efficacy and safety of transcatheter closure of patent ductus arteriosus (PDA) with transthoracic echocardiography (TTE).MethodsFrom February 2016 to November 2018, 98 patients of pure PDA were selected, including 43 patients of funnel type and 55 patients of tube type. There were 38 males and 60 females at age of 2-48 (9.8±10.4) years. All patients underwent TTE-guided retrograde closure of the PDA through the femoral artery to establish a femoral-abdominal aorta-thoracic aorta-ductus arteriosus-aorta-right ventricle trajectory.Under the guidance of TTE, a suitable closure umbrella was placed through the femoral artery. One month, 3 months, 6 months, 12 months after the surgery, the patients received out-patient clinical follow-up.ResultsNinety eight patients were successfully occluded by TTE. The occluder was replaced many times in an adult PDA patient, but finally it was successfully plugged. The operation time was 33.2±5.8 min. The lumbar diameter was 12±6 mm. And the postoperative murmur disappeared. Ultrasound showed no shunt between the aorta and the pulmonary artery, and the postoperative hospital stay was 3-4 days. No shunt signal was found in 1, 3, 6, 12 months follow-up. Left atrial anteroposterior diameter (25.8±6.1 mm vs. 30.6±8.4 mm) and left ventricular end diastolic diameter (38.5±9.1 mm vs. 45.2±11.5 mm) were significantly smaller (P < 0.05).ConclusionTTE-guided transcatheter closure of PDA via femoral artery is a safe and effective method to avoid the damage of X-ray and contrast medium. The prospect of clinical application is good.

    ObjectiveTo investigate the effectiveness and safety of esophageal ultrasound-guided percutaneous femoral artery closure of ventricular septal defect (VSD).MethodsThe clinical data of 24 patients with congenital VSD in our hospital from March 2017 to December 2019 were retrospectively analyzed, including 6 males and 18 females, with a median age of 12 (3-42) years, weight of 32 (12-91) kg, and VSD diameter of 4 (3-7) mm. There were 3 patients with VSD combined with atrial septal defect.ResultsTwenty-four patients successfully underwent interventional closure of percutaneous femoral artery under esophageal ultrasound guidance, and the position and shape of the occluders were good. The operation time was 45 (39-54) min, and the waist size of the occluders was 7 (5-12) mm. Among the patients, 14 patients used symmetric ventricular occlusion devices, 8 patients used asymmetric ventricular occlusion devices, and 2 patients used ventricular occlusion muscle occluders. Small amount of residual shunt occurred in 2 patients after the operation and it disappeared 3 months after the operation. One patient with right bundle branch block, which disappeared after 1 week of observation. There were no complications such as occluder closure, pericardial effusion or valve regurgitation during the perioperative period. During the follow-up period [3-18 (9.25±5.04) months], no serious complication occurred.ConclusionTransesophageal ultrasound-guided transfemoral artery occlusion for VSD is simple and safe, and it avoids the damage of radiation and contrast medium.

  • Treatment of patent ductus arteriosus via ultrasound-guided percutaneous antegrade or retrograde access: A retrospective cohort study

    ObjectiveTo compare the surgical results of ultrasound-guided percutaneous antegrade or retrograde therapy in the treatment of patent ductus arteriosus.MethodsThe clinical data of 166 patients (44 males and 122 females) who underwent transthoracic echocardiography guided closure of patent ductus arteriosus in Xinjiang Cardiovascular and Cerebrovascular Disease Hospital from February 2016 to August 2020 were retrospectively analyzed, and the patients were divided into two groups: an antegrade group (n=60) and a retrograde group (n=106). The operation time, success rate, bed rest time, postoperative complications and surgical safety were compared between the two groups.ResultsThe immediate success rate of the two groups was 100.0%. Compared with the retrograde group, the antegrade group had shorter time of bed rest and hospital stay, but longer operation time. In the retrograde group, there were 2 patients of complications, including occlusive device falling off to pulmonary artery 12 hours after the operation in 1 patient, and false arterial tumor in 1 patient. Both groups were followed up for 3-18 months, and there was no death in the whole group.ConclusionIt is safe and effective to block patent ductus arteriosus under the guidance of transthoracic echocardiography. Although the operation process of anterior occlusion of patent ductus arteriosus is slightly complex and the operation time is long, the indication is wide, and the bed rest time is short. Therefore it can be used as the first choice for patent ductus arteriosus occlusion.

    Objective To introduce the application of transcatheter closure of multi-fenestrated atrial septal defect (ASD) via femoral vein under ultrasound guidance with amplatzer cribriform occluder (ACO) and atrial septal defect occluder (ASDO), as well as to assess its feasibility, effectiveness and safety. Methods The clinical data of 48 patients with fenestrated ASD occluded via femoral vein under ultrasound guidance from December 2015 to May 2018 in our hospital were retrospectively analyzed, including 17 males and 31 females, aged 10 months to 51 years, an average of 11.50±13.86 years, and weighting 6-79 (27.00±20.14) kg. Among 48 patients with fenestrated ASD, 12 patients had double-foramen and 13 atrial septal aneurysm combined with defects and 23 multi-foramen. All patients underwent transthoracic echocardiography (TTE) or transesophageal echocardiography (TEE) to complete the closure of fenestrated ASD. Ultrasound, electrocardiogram and chest X-ray were reviewed the next day after surgery to evaluate the curative effect. Results Forty-eight patients with ASD were treated with 49 occluders, due to one patient with two occluders. There were 29 ASDO (8-26 mm) and 20 ACO (18-34 mm). During the operation, TTE/TEE examination showed that 48 patients were completely occluded, 13 patients showed fine bundle shunt in the unreleased push notification rod, and 9 patients had fine bundle shunt after the release of push notification rod. Fine bundle shunt was found in 8 patients 24 hours after operation, and microshunt was found in 3 patients 1 year after operation. All the patients were followed up. The occluder position was good. The right heart was reduced in different degrees, and the X-ray showed that the pulmonary blood was reduced in different degrees. No arrhythmia was found by electrocardiogram after operation. Conclusion It is a safe and effective method to use ACO and ASDO to occlude ASD through femoral approach under ultrasound guidance.
