Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.
Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

ABSTRACT Purpose: This study aims to evaluate the safety and efficacy of ultrasound-guided balloon dilation compared to non-balloon dilation for percutaneous nephrolithotomy (PCNL). Materials and methods: A systematic review and meta-analysis were conducted by searching PubMed, EMBASE, and the Cochrane Library. Results were filtered using predefined inclusion and exclusion criteria as described and meta-analysis was performed using Review Manager 5.4 software. Results: A total of six studies involving 1189 patients who underwent PCNL were included. The meta-analysis results demonstrated that compared to non-balloon dilation, balloon dilation was associated with reduced haemoglobin drop [mean difference (MD) = -0.26, 95% CI = -0.40 ~ -0.12, P = 0.0002], decreased transfusion rate [odds ratio (OR) = 0.47, 95% CI = 0.24 ~ 0.92, P = 0.03], shorter tract establishment time (MD = -1.30, 95% CI = -1.87 ~ -0.72, P < 0.0001) and shorter operation time (MD = -5.23, 95% CI = -10.19 ~ -0.27, P = 0.04). Conclusions: Overall, ultrasound-guided balloon dilatation offered several advantages in PCNL procedures. It facilitated faster access establishment, as evidenced by shorter access creation time. Additionally, it reduced the risk of kidney injury by minimizing postoperative haemoglobin drop and decreasing the need for transfusions. Moreover, it enhanced the efficiency of surgery by reducing the operation time. However, it is important to note that the quality of some included studies was subpar, as they did not adequately control for confounding factors that may affect the outcomes. Therefore, further research is necessary to validate and strengthen these findings.

Objective To investigate the diagnosis and treatment strategy of the portal vein complications in children undergoing split liver transplantation. Methods The clinical data of 88 pediatric recipients who underwent split liver transplantation were retrospectively analyzed. Intraoperative anastomosis at the bifurcating site of the portal vein or donor iliac vein bypass anastomosis was performed depending on the internal diameter and development of the recipient's portal vein. A normalized portal venous blood stream monitoring was performed during the perioperative stage. After operation, heparin sodium was used to bridge warfarin for anticoagulation therapy. After portal vein stenosis or thrombosis was identified with enhanced CT or portography, managements including embolectomy, systemic anticoagulation, interventional thrombus removal, balloon dilatation and/or stenting were performed. Results Among the 88 recipients, a total of 10 children were diagnosed with portal vein complications, of which 4 cases were diagnosed with portal vein stenosis at 1 d, 2 months, 8 months, and 11 months after surgery, and 6 cases were diagnosed with portal vein thrombosis at intraoperative, 2 d, 3 d (n=2), 6 d, and 11 months after surgery, respectively. One patient with portal vein stenosis and one patient with portal vein thrombosis died perioperatively. The fatality related to portal vein complications was 2% (2/88). Of the remaining 8 patients, 1 underwent systemic anticoagulation, 2 underwent portal venous embolectomy, 1 underwent interventional balloon dilatation, and 4 underwent interventional balloon dilatation plus stenting. No portal venous related symptoms were detected during postoperative long term follow up, and the retested portal venous blood stream parameters were normal. Conclusions The normalized intra- and post-operative portal venous blood stream monitoring is a useful tool for the early detection of portal vein complications, the early utilization of useful managements such as intraoperative portal venous embolectomy, interventional balloon dilatation and stenting may effectively treat the portal vein complications, thus minimizing the portal vein complication related graft loss and recipient death.
Résumé
@#BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) can temporarily control traumatic bleeding. However, its prolonged use potentially leads to ischemia-reperfusion injury (IRI). Partial REBOA (pREBOA) can alleviate ischemic burden; however, its security and effectiveness prior to operative hemorrhage control remains unknown. Hence, we aimed to estimate the efficacy of pREBOA in a swine model of liver injury using an experimental sliding-chamber ballistic gun. METHODS: Twenty Landrace pigs were randomized into control (no aortic occlusion) (n=5), intervention with complete REBOA (cREBOA) (n=5), continuous pREBOA (C-pREBOA) (n=5), and sequential pREBOA (S-pREBOA) (n=5) groups. In the cREBOA and C-pREBOA groups, the balloon was inflated for 60 min. The hemodynamic and laboratory values were compared at various observation time points. Tissue samples immediately after animal euthanasia from the myocardium, liver, kidneys, and duodenum were collected for histological assessment using hematoxylin and eosin staining. RESULTS: Compared with the control group, the survival rate of the REBOA groups was prominently improved (all P<0.05). The total volume of blood loss was markedly lower in the cREBOA group (493.14±127.31 mL) compared with other groups (P<0.01). The pH was significantly lower at 180 min in the cREBOA and S-pREBOA groups (P<0.05). At 120 min, the S-pREBOA group showed higher alanine aminotransferase (P<0.05) but lower blood urea nitrogen compared with the cREBOA group (P<0.05). CONCLUSION: In this trauma model with liver injury, a 60-minute pREBOA resulted in improved survival rate and was effective in maintaining reliable aortic pressure, despite persistent hemorrhage. Extended tolerance time for aortic occlusion in Zone I for non-compressible torso hemorrhage was feasible with both continuous partial and sequential partial measures, and the significant improvement in the severity of acidosis and distal organ injury was observed in the sequential pREBOA.

Objective:To explore the clinical therapeutic effect and safety of noncompliant balloon post-dilatation(PD)during emergency percutaneous coronary intervention(PCI)in patients with acute ST-segment elevation my-ocardial infarction(STEMI)and type 2 diabetes mellitus(T2DM)with low thrombus burden.Methods:A total of 122 STEMI±T2DM patients,who underwent emergency PCI in our hospital from Jan 2016 to Dec 2021,were con-secutively enrolled.According to PD therapy after PCI or not,they were divided into PD group(n=78)and non-PD group(n=44).Clinical data,PCI condition,postoperative TIMI blood flow,ST-segment elevation index res-olution(∑STIR),incidence rate of the major adverse cardiac events(MACE)during hospital and LVEF,incidence rates of in-stent restenosis and MACE within one year after PCI were compared between two groups.Results:Compared with non-PD group,there were significant reductions in incidence rate of MACE during hospital(15.9%vs.3.8%),incidence rates of in-stent restenosis(14.3%vs.2.6%)and MACE within one year after PCI(21.4%vs.2.6%)in PD group(P<0.05 or<0.01),there were significant rise in LVEF within one year after PCI[58.50(52.75,65.25)%vs.64.00(58.25,67.50)%]in PD group(P=0.005).Conclusion:It's safe and feasible to apply noncompliant balloon PD during emergency PCI in STEMI+T2DM patients with low thrombus bur-den.It can reduce incidence rate of MACE during hospital,in-stent restenosis and MACE within one year after PCI,and improve left heart function of patients,and provide clinical reference for the use of PD therapy in emer-gency PCI for these patients.
Résumé
Congenital pulmonary valve stenosis(PS)is a common congenital heart disease. Simple PS makes up approximately 8%~10% of congenital heart disease,and 20% of complex congenital heart disease complicated with PS. Percutaneous balloon pulmonary valvuloplasty(PBPV),which has undergone nearly 40 years of continuous improvement,has emerged as the preferred treatment for PS due to its superior safety and less trauma. However,residual stenosis was found in some patients during long-term follow-up,and repeat PBPV or even surgical repair was required. Identifying the risk factors for postoperative restenosis will further improve postoperative outcomes and reduce the probability of reintervention in the future. This article reviews the risk factors for restenosis of PS after PBPV including age,severity,morphologic characteristics of the valve leaflets and the choice of the balloon.

Objective:There are a variety of minimally invasive interventional treatments for trigeminal neuralgia,and the efficacy evaluation is different.The preferred treatment scheme is still controversial.This study aims to investigate the differences in treatment effects between patients with primary trigeminal neuralgia(PTN)treated with percutaneous balloon compression(PBC)for the first intervention and patients with pain recurrence after radiofrequency thermocoagulation(RT)who then received PBC for PTN,and to offer clinicians and patients more scientifically grounded and precise treatment alternatives. Methods:We retrospectively analyzed 103 patients with PTN admitted to the Department of Pain Management of the Second Affiliated Hospital of Guangxi Medical University from January 2020 to December 2021,including 49 patients who received PBC for the first time(PBC group)and 54 patients who received PBC for pain recurrence after RT(RT+PBC group).General information,preoperative pain score,intraoperative oval foramen morphology,oval foramen area,balloon volume,duration of compression,and postoperative pain scores and pain recurrence at each time point on day 1(T1),day 7(T2),day 14(T3),1 month(T4),3 months(T5),and 1 year(T6)were collected and recorded for both groups.The differences in treatment effect,complications and recurrence between the 2 groups were compared,and the related influencing factors were analyzed. Results:The differences of general information,preoperative pain scores,foramen ovale morphology,foramen ovale area,T1 to T3 pain scores between the 2 groups were not statistically different(all P>0.05).The balloon filling volume in the PBC group was smaller than that in the RT+PBC group,the pain scores at T4 to T6 and pain recurrence were better than those in the RT+PBC group(all P<0.05).Pain recurrence was positively correlated with pain scores of T2 to T6(r=0.306,0.482,0.831,0.876,0.887,respectively;all P<0.01). Conclusion:The choice of PBC for the first intervention in PTN patients is superior to the choice of PBC after pain recurrence after RT treatment in terms of treatment outcome and pain recurrence.

Objective:To evaluate the clinical efficacy of individualized thrombolysis-assisted comprehensive intervention for deep vein thrombosis (DVT) in the lower limbs.Methods:This study included 32 patients with acute lower limb DVT diagnosed by angiography who received treatment at the Jianhu Clinical Medical College of Yangzhou University from March 2012 to November 2021. These patients first received implantation of an inferior vena cava filter. Then they were divided into a control group and an observation group based on treatment methods. The control group received thrombolytic catheterization and a routine infusion of urokinase. In the observation group, balloon dilation was performed first, and a large lumen catheter was used to draw blood clots. Subsequently, urokinase at a dose based on fibrinogen measurement was injected through a thrombolytic catheter. Swelling reduction, venous patency, and complications of the affected limbs were monitored.Results:In the control group, the difference in thigh circumference before treatment was (4.65 ± 1.06) cm, and after treatment, it was (2.76 ± 1.25) cm. In the observation group, the difference in thigh circumference before treatment was (4.73 ± 1.03) cm, and it was (1.40 ± 0.83) cm after treatment. In the control group, the difference in calf circumference before treatment was (2.24 ± 0.90) cm, and it was (1.56 ± 0.86) cm after treatment. In the observation group, the difference in calf circumference before treatment was (2.40 ± 0.83) cm, and it was (0.80 ± 0.73) cm after treatment. After treatment, the differences in thigh circumference and calf circumference between the healthy and affected sides were statistically significant ( t = 3.58, 2.67, both P < 0.05). After treatment, there was a significant difference in venous patency between the control and observation groups (34.02% [33/97] vs. 68.18% [60/88], t = 3.44, P < 0.05). After 12 months of follow-up, the Villalta scale score, which was used to evaluate post-thrombotic syndrome, was (9.23 ± 4.07) points in the control group, which was significantly different from (5.73 ± 3.39) points in the observation group ( t = 2.62, P < 0.05). Conclusion:Individualized thrombolysis-assisted comprehensive intervention is highly effective in the treatment of DVT in the lower limbs and results in few complications.
Résumé
Coronary artery calcification commonly results in reduced vascular compliance,facilitating incomplete stent expansion and in-stent restenosis after stent implantation,thereby leading to the failure of interventional treatment.Conventional approaches to managing calcified lesions are constrained by the intricate nature and properties of calcified plaques,which frequently pose challenges in their manipulation,consequently giving rise to numerous approaches complications and an elevated likelihood of adverse cardiovascular events following the procedure.Percutaneous coronary intraluminal shock wave balloon catheter angioplasty,also known as coronary intravascular lithotripsy,utilizing a balloon catheter system,demonstrates the capacity to safely and efficiently modify superficial and deep-seated calcifications,regardless of their concentric or eccentric nature.This intervention significantly enhances vascular compliance,thereby facilitating subsequent interventional therapies.Presently,coronary intravascular lithotripsy has emerged as a crucial approach in the management of coronary artery calcification.This article primarily offers a comprehensive examination of the mechanism of intravascular lithotripsy and the research pertaining to the treatment of coronary artery calcification.

Objectives:To evaluate the efficacy and safety of drug-coated balloon in the treatment of de novo coronary chronic occlusive lesions. Methods:Consecutive patients with de novo coronary chronic occlusive lesions treated with drug-coated balloons only were included in this study.The general information,medical history,and surgical information of the patients were recorded,and major adverse cardiovascular events(MACE,including cardiac death,myocardial infarction,and target vessel revascularization)were recorded by telephone or outpatient follow-up. Results:A total of 160 patients were included.There were 26 ostial lesions(16.3%),42 bifurcated lesions(26.3%),117 diffuse lesions(73.1%),and 87 calcified lesions(54.4%).The reference vessel diameter was(2.3±0.4)mm.During hospitalization,there were no acute myocardial infarction,cardiac death,target lesion revascularization,or acute coronary thrombosis.Cardiac death occurred in 1 case and target vessel revascularization occurred in 6 cases during follow-up.The MACE rate is 4.4%. Conclusions:Drug balloon therapy for de novo coronary chronic occlusive lesions is safe and effective,and the prognosis is satisfactory.
Résumé
Objectives:To compare the efficacy of the combination of excimer laser coronary angioplasty(ELCA)and drug-coated balloon(DCB)for in-stent restenosis(ISR)and to evaluate the impact of neointimal tissue characteristics on treatment outcomes. Methods:A total of 96 ISR lesions from 86 patients who underwent optical coherence tomography(OCT)evaluation and DCB with or without ELCA treatment at The First Medical Center of Chinese PLA General Hospital from January 2019 to May 2023 were retrospectively analyzed.ISR lesions were divided into ELCA+DCB group(n=30)and DCB group(n=66).Additionally,ISR lesions were classified as homogeneous and non-heterogeneous patterns based on the OCT characteristics of the neointimal tissue,and the impact on acute lumen gains was compared between different ISR patterns.Acute lumen gain(ΔMLA)was defined as the changes in minimum lumen area before and after the intervention. Results:The ELCA+DCB group had a significantly greater ΔMLA than the DCB group([3.2±0.8]mm2 vs.[2.6±1.4]mm2,P=0.015).Among the ISR with a homogeneous pattern,the ΔMLA of the ELCA+DCB group was significantly greater than that of the DCB group([3.0±0.9]mm2 vs.[2.2±1.1]mm2,P=0.030).There was no significant difference in ΔMLA between the two ISR groups with the non-homogeneous pattern([3.4±0.7]mm2 vs.[3.2±1.5]mm2,P=0.533).There was no death,the rate of target lesion revascularization was similar between the patients with lesions receiving DCB treatment and patients receiving ELCA +DCB treatment(7.4%vs.4.2%,P>0.05). Conclusions:The combination of ELCA and DCB is an effective strategy for treating ISR,which can achieve greater acute lumen gain compared to DCB treatment alone,especially for the treatment of homogenous ISR pattern characterized by OCT.
