ABSTRACT

@#Objective    To summarize the surgical strategy of reoperative aortic root replacement after prior aortic valve replacement (AVR), and analyze the early and mid-term outcomes. Methods    From April 2013 to January 2020, 75 patients with prior AVR underwent reoperative aortic root replacement in Fuwai Hospital. There were 54 males and 21 females with a mean age of 56.4±12.7 years. An emergent operation was performed in 14 patients and an elective operation in 61 patients. The indications were aortic root aneurysm in 38 patients, aortic dissection involving aortic root in 30 patients, root false aneurysm in 2 patients, prosthesis valve endocarditis with root abscess in 2 patients, and Behçet's disease with root destruction in 3 patients. The survival and freedom from aortic events during the follow-up were evaluated with the Kaplan-Meier survival curve and the log-rank test. Results    The operative procedures included prosthesis-sparing root replacement in 45 patients, Bentall procedure in 26 patients, and Cabrol procedure in 4 patients. Operative mortality was 1.3% (1/75). A composite of adverse events occurred in 5 patients, including operative death (n=1), stroke (n=1), and acute renal injury necessitating hemodialysis (n=3). The follow-up was available for all 74 survivors, with the mean follow-up time of 0.5-92.0 (30.3±25.0) months. Four late deaths occurred during the follow-up. The survival rate at 1 year, 3 years and 6 years was 97.2%, 91.4% and 84.4%, respectively. Aortic events developed in 2 patients. The rate of freedom from aortic events at 1 year, 3 years, and 6 years was 98.7%, 95.0% and 87.7%, respectively. There was no difference in rate of survival or freedom from aortic events between the elective patients and the emergent patients. Conclusion    Reoperative aortic root replacement after prior AVR can be performed to treat the root pathologies after AVR, with acceptable early and mid-term outcomes.

ABSTRACT

Objective:To investigate the clinical features of neonatal testicular torsion and to evaluate the effect and necessity of early intervention.Methods:A retrospective analysis was performed on 11 neonates admitted to the Second Hospital of Shandong University with neonatal testicular torsion from June 2017 to June 2022. Clinical data of these cases including clinical manifestations, ultrasonography findings, surgical management and outcomes were reviewed and analyzed with descriptive statistical methods.Results:The median age of the 11 patients on admission was 2.6 d (1-5 d). The median time from finding abnormal scrotum to admission was 12 h (1-120 h). Various degrees of scrotal swelling or scleroma were found in the patients. Among them, seven patients presented with acute inflammatory signs of cyano sis or skin redness, and testis-like tissue induration could be touched. Ultrasound scan showed abnormal blood flow in the affected testicle in all cases. Emergency scrotal exploration under general anesthesia was performed successfully in all cases and ten of them underwent orchiectomy of the affected testicle plus contralateral orchiopexy. The rest one who was admitted within 1 h after birth only underwent orchiopexy of the affected testicle as the parents refused contralateral testicular exploration. During the operation, 12 twisted testis were observed, including seven with extravaginal torsion, three with intravaginal torsion and two adhering to the surrounding tissue without normal testicular tissue or distinguishable torsion direction or degree. In this study, ten patients had unilateral testicular torsion, which affected the left side in seven cases and the right side in three cases, and one had bilateral testicular torsion, which was diagnosed as left testicle torsion before surgery. During scrotal exploration, the left testicle of this bilateral case was resected due to necrosis, while the right testicle twisted about 180 degrees with good blood flow and was subjected to orchidopexy after reduction. In one case, the unaffected testicle was unfixed and dysplastic during contralateral exploration, which was also subjected to orchidopexy. In the 12 testis with torsion, one testicle of the patient admitted within 1 h after birth and the right testicle of the bilateral case were preserved with a salvage rate of 2/12. Pathological examination showed necrosis in the ten excised testis, and fibrosis and calcification foci in two of them. None of the patients had any perioperative complications and the scrotal incision healed well in all neonates. The patients were followed up for 6-12 months with regular ultrasound. The two preserved testis and the contralateral testis subjected to orchidopexy were located in the scrotum with good blood supply, and no torsion, atrophy or other abnormalities occurred.Conclusions:Neonatal testicular torsion is rarely seen in clinical practice and has no specific manifestations. It has a high excision rate due to testicular necrosis. Early diagnosis and bilateral scrotal exploration are crucial to the prognosis and the keys to save the affected testis and avoid anorchidism.

ABSTRACT

Objective:To evaluate the clinical effects of " watching without dealing" aortic root repair technique in acute Stanford type A aortic dissection(ATAAD).Methods:From October 2017 to October 2018, " watching without dealing" technique was performed in ATAAD patients with mild aortic root involvement. The proximal aortic anastomosis was at the level of the sinotubular junction, without " pursuing" complete excision of the intra-sinus dissections. The perioperative clinical data and follow-up imaging results of the patients were collected and analyzed to evaluate early and mid-term efficacy of the technique.Results:A total of 20 patients received " watching without dealing" technique in our hospital, including 15 males and 5 females with a mean age of(48.0±12.1) years old(34-73 years old). The preoperative aortic sinus diameter was(41.3±3.6)mm and the aortic sinotubular junction diameter was(43.9±6.6) mm. All patients underwent ascending aortic replacement and total arch replacement plus frozen elephant trunk surgery. The cardiopulmonary bypass time was(179.5±41.5)min(132~255 min), the cross-clamp time was(120.3±23.7) min(95~180 min), and the circulatory arrest time was(8.8±7.6) min(2~22 min). During perioperative period, no adverse events such as death, secondary opening, renal failure, cerebral infarction, and paraplegia occurred. The CTA examination of the aorta before the patients were discharged showed that all residual false lumen in the sinus disappeared, the diameter of the aortic sinus was(30.8±2.6) mm, and the diameter of the aortic sinotubular junction was(27.2±2.5) mm. The patients were followed up for mean(28.5±7.8) months(3~35 months). No surgical re-intervention of the aortic root occurred. The aortic CTA during follow-up period showed no residual or new dissection in the aortic sinus, the diameters of the aortic sinus and aortic sinotubular junction were(30.9±2.4) mm and(27.5±2.7) mm respectively; the ultrasonic cardiogram showed normal aortic valve structure and function. No statistically significant differences were found when comparing the aortic sinus diameter and aortic sinotubular junction diameter between two time points of at discharge and follow-up.Conclusion:The " watching without dealing" aortic root repair technique for ATAAD is relatively simple to learn and safe in the perioperative period. Early and mid-term follow-up imaging showed normalization of the aortic sinus structure. Further follow-up and observation were necessary to figure out the long-term clinical outcome of this modified aortic root repair.

ABSTRACT

Objective:To investigate the clinical characteristics and therapeutic laparoscopy treatment for superior mesenteric artery syndrome(SMAS) in children.Methods:A retrospective study on 5 children with SMAS who failed to respond to the conservative treatment in the Second Hospital of Shandong University from March 2017 to March 2022 was carried out.All the patients underwent the laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure.The clinical data were analyzed and literature retrieved from Wanfang and PubMed databases were reviewed.Results:There were 3 boys and 2 girls in the 5 cases with SMAS.The average age was (12.4±1.4) years, and the preoperative body mass index was (15.2±0.8) kg/m 2.The patients were admitted to the hospital with vomiting, abdominal pain and emaciation symptoms, and the duration of symptoms was (8.4±7.8) months.Gastroscopy, laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure were performed successfully in all the patients, without conversions to open surgery.The average operation duration was (66.0±10.7) min.Food intake was allowed 1 day after surgery.Chylous fistula occurred 4 days after operation in one patient, whose symptom relieved after 11 days of conservative treatment.One patient still had nausea and vomiting symptoms 10 days after operation and was healed by knee-chest posture treatment.No other short-term complications were observed.The median postoperative duration of stay in the hospital was 7 (6-22) days.The patients were followed up for 9-56 (median: 21) months.All of them recovered well and gained weight.One patient had mild recurrent symptoms, and was cured after conservative treatment.A total of 15 literature on the treatment of SMAS by laparoscopic lysis of the ligament of Treitz was retrieved, and the cure rate was 40%-100%.Only one group of these cases had a cure rate below 75%. Conclusions:The laparoscopic lysis of the ligament of Treitz and duodenal lowering procedure is safe, effective, simple and minimally invasive treatment for children with SMAS.It can be used as the first choice for most pediatric patients.

ABSTRACT

Objective:To evaluate the short-term outcomes of aortic root repair using a pericardial autograft for acute type A aortic dissection.Methods:Between January 2020 and August 2021, 12 patients underwent aortic root repair using a pericardial autograft for type A aortic dissection. There were 8 males and 4 females, aged from 32.0 to 71.0 years, with a mean of (49.1±13.0) years, weight from 40.0 to 100.0 with a mean of (78.6±20.5) kg. Short-term outcomes were assessed by cardiopulmonary bypass time, cross-clamp time, circulatory arrest time, mechanical ventilation time, ICU time, postoperative stay time. The diameter of Valsalva sinus and aortic regurgitation were assessed before, after operation and during follow-up.Results:There were no postoperative and follow-up death. Cardiopulmonary bypass time was(256.4±60.6)min, ranging from 182.0 to 243.0 minutes; cross-clamp time was(195.0±52.5)minutes, ranging from 127.0 to 284.0 minutes; circulatory arrest time was(19.9±3.6)min, ranging from 15.0 to 25.0 min; mechanical ventilation time was (69.1±72.1)hours, ranging from 6.4 to 250.3 h; ICU time was (143.6±81.7) h, ranging from 56.9 to 288.0 h; postoperative stay time was (12.8±4.1) days, ranging from 8.0 to 20.0 days. One patient had transient paralysis (8.3%), and one patient needed hemofiltration due to acute kidney failure (8.3%), they all completely recovered before discharge. Follow-up time ranged from 10.0 to 21.0 months, with a median of 13 months. Heart function (NYHA) was I to II degrees. The mean diameter of aortic root was (36.7±5.8)mm(27.0-45.0 mm) preoperatively, (35.8±5.1)mm (25.0-44.8 mm) before discharge, and (35.7±5.9)mm (25.1-44.8 mm) during follow-up, respectively. There was no significant difference between them ( P>0.05). The preoperative aortic regurgitation was as follow: severe aortic regurgitation 2, moderate 1, mild to moderate 3, mild 1, trivial 1, none 4; postoperative aortic regurgitation: mild 2, trivial 2, none 8; follow-up aortic regurgitation: mild 3, trivial 1, none 8. Conclusion:Aortic root repair with a pericardial autograft is a safe and effective technique to treat acute type A dissection involving the sinus. Using this technique, residual dissection tissues could be significantly reduced, which subsequently decreases the risk of proximal bleeding, maintains the function of sinus, and increases long-term durability. Short-term results are satisfactory, and the long-term results need further follow-up.

ABSTRACT

Objective:To evaluate the short-term outcomes of cuff wrapping technique using remnant aortic wall in modified Bentall procedure.Methods:Between January 2018 and December 2018, 23 patients underwent modified Bentall procedure with the remnant aortic wall as a cuff to cover the sewing area of composite valved graft and the aortic annulus for proximal hemostasis. After the sewing ring of the composite valved graft was sutured to the aortic annulus by continuous suture, the remnant aortic wall was sutured to the graft just distal to the sewing ring by continuous suture. There were 21 males and 2 females, aged from 22 to 72 with a mean of(50.96±13.23)years. Short-term outcomes were assessed by cardiopulmonary bypass time, clamp aorta time, mechanical ventilation time, ICU time, postoperative stay time, effusion drainage till the first postoperative day, Left ventricular end diastolic diameter(LVEDD), left ventricular ejection fraction(LVEF), and follow-up results.Results:There were no postoperative and follow-up death. Cardiopulmonary bypass time was(157.74±39.85)min, ranged from 114 to 275 min; clamp aorta time(122.61±30.25)min, ranged from 84 to 212 min; mechanical ventilation time(11.65±3.08)h, ranged from 7.87 to 20.33 h; ICU time(81.43±45.88) h, ranged from 15.18 to 184.77 h; postoperative stay time(8.73±2.80)days, ranged from 6 to 15 days. Effusion drainage was(336.82±117.65)ml, ranged from 200 to 670 ml till the first postoperative day. Follow-up was performed from 19 to 30 months, with a mean of(23.17±3.17)months. There were significant differences between preoperative LVEDD and postoperative LVEDD before discharge[(49.78±6.21)mm vs.(58.78±10.54)mm, P<0.05]; There were a little decrease of follow-up LVEDD compared with postoperative LVEDD, but no significant difference between them[(48.87±4.63)mm vs.(49.78±6.21)mm, P>0.05] . There were a little decrease of postoperative LVEF compared with preoperative LVEF, but no significant difference between them(0.57±0.07 vs. 0.59±0.05, P>0.05). There were significant differences between follow-up LVEF and preoperative LVEF(0.62±0.04 vs. 0.57±0.07, P<0.05), postoperative LVEF before discharge( P<0.05). Conclusion:Cuff wrapping technique using remnant aortic wall in modified Bentall procedure has got good short-term results. This modification may be a simple, effective way in controlling proximal bleeding.

ABSTRACT

Objective:To compare the mid-term result of two different valve-sparing root replacement techniques in acute type A aortic dissection: including reimplantation and remodeling.Methods:From March 2009 to December 2019, 41 patients with acute type A dissection and root involvement, who underwent a valve-sparing root replacement using reimplantation(36 cases) or remodeling(5 cases) were retrospectively analyzed in current study. The average age was(44.63±11.34) years old, 36 males. The differences of perioperative variables, postoperative aortic insufficiency and postoperative survival were compared between the two groups.Results:Thirty-day mortality for two groups was 2.8% and 20%( P=0.23). Remodeling group was significantly inferior to reimplantation group in terms of blood consumption(red blood cells, plasma and platelets), postoperative mechanical ventilation time, reoperation for bleeding and hemofiltration for acute renal failure. The median follow-up time of 39 discharged survivors was 34.56(3-121) months, and the follow-up rate was 100%. There was no follow-up death, no bleeding or embolism events, and no cardiovascular reoperation. Grade 2 or sever aortic regurgitation in remodeling group was significantly higher than that in reimplantation group( P=0.02). A Cox regression analysis identified that the remodeling technique was the independent risk factors of postoperative aortic regurgitation. Conclusion:Compared with remodeling technique, reimplantation technique has better perioperative and mid-term results in patients with acute type A aortic dissection. The rate of reoperation for bleeding, the blood consumption and the postoperative aortic regurgitation are significantly reduced. The long-term results need further follow-up.

ABSTRACT

@#Aortic arch disease is one of the research hotspots and treatment difficulties in the field of aorta, including aortic arch aneurysms, pseudoaneurysm, ulcer, dissection and intramural hematoma. By summarizing the clinical data of the vascular surgery center of Fuwai Hospital of Chinese Academy of Medical Sciences in the past five years and combining with the latest theories of the cutting-edge development of aortic surgery, the authors proposed the "HENDO" concept, including using hybrid technique (H), endovascular repair (Endo) and open surgery (O), properly to treat aortic arch pathologies individually. The authors advocated the establishment of HENDO team and cooperation mechanism in large aortic centers, to eliminate technical shortcomings of a single surgeon by fully mastering the three main technology clusters by teamwork. Accordingly, the best treatment for each patient can be administrated and the survival rate and quality of life can be improved eventually.

ABSTRACT

To evaluate the early and mid-term results after surgical repair of thoracoabdominal aortic aneurysm(TAAA)in patients with DeBakey typeⅠor Ⅲ aortic dissection. The clinical data of 130 patients who underwent TAAA repair for chronic DeBakey typeⅠ(groupⅠ, =47)or type Ⅲ(group Ⅲ, =83)aortic dissections in our center between January 2009 and December 2017 were retrospectively analyzed.Early postoperative results,midterm survival,and re-interventions were compared between these two groups. The 30-day mortality rate was 6.9%(=9)in the overall cohort,with no statistic difference between groupⅠand group Ⅲ(10.6% 4.8%;=0.803, =0.370).The incidence of major adverse events(38.3% 51.8%;=2.199, =0.138),5-year actuarial survival rate [(81.7±5.9)% (87.2±4.2)%;=0.483, =0.487],and 5-year actuarial freedom from all reinterventions [(84.5±6.7)% (85.5±4.8)%;=0.010, =0.920] showed no significant differences between these two groups. The early and mid-term outcomes after surgical repair of TAAA are similar for DeBakey typeⅠ and type Ⅲ patients.However,studies with larger sample sizes are still required.

ABSTRACT

Objective:By analyzing the early- and mid-term clinical results of type Ⅱ hybrid aortic arch repair(HAAR) for the treatment of acute type A aortic dissection(ATAAD), the efficacy of hybridization technique in the application of acute type A aortic dissection was evaluated systematically.Methods:We retrospectively studied the records of patients with ATAAD who were admitted to the Beijing Fuwai Hospital between January 2016 and December 2018. 504 patients were included for analysis , 383 men and 121 women, mean age(50.0±11.7) years, the rate of hypertension was 79.6%, the average time of onset to operation was(69.5±40.0) hours. During this period, 110 continuous patients underwent hybrid aortic arch repair(HAAR) without deep hypothermic circulatory arrest, the landing zone of stent was located in ascending aorta(zone 0); 394 consecutive patients with ATAAD involving the aortic arch received traditional total aortic arch replacement with frozen elephant trunk(FET). A propensity score-matching analysis was applied to adjust for age and gender.The preoperative, perioperative and postoperative data in the HAAR group and FET group were compared.Results:For all 504 patients , male patients accounted for 75.9%. There were 24 cases of early death(4.8%), 20 cases of stroke(4.0%) and 7 cases of paralysis(1.4%). HAAR group showed more age[(62.1±6.8) years vs (46.6±10.4) years, P<0.001)], hypertension(87.3% vs 77.4%, P=0.033), coronary artery disease(13.6% vs 6.1%, P=0.016) and chronic obstructive pulmonary diseases(12.7% vs 3.6%, P=0.001) than the FET group. HAAR group showed shorter cardiopulmonary bypass time[(143.7±53.7) min vs (175.3±52.7) min, P<0.001] and aortic cross-clamping time[(78.5±33.6) min vs (106.9±37.8) min, P<0.001] than the FET group. Between the two groups there was no significant difference in operative mortality, rate of reoperation, and late mortality. Follow-up period ranged from 2 to 43 months, averaged(22.6±11.1) months. During folloe-up period , there were 5 cases of death(4.9%) and 3 cases of reoperation(3.1%) in HAAR group, 10 cases of death(2.7%) and 11 cases of reoperation(3.3%) in FET group. 3 patients lost follow-up because of not been rechecked in the outpatient department or the phone was not connected. Conclusion:This single -stage hybrid arch procedure offers an alternative approach to acute type A dissection and associated with acceptable early and midterm major morbidity and mortality in old-age patients. Future further researches are required to confirm the long-term outcomes.

ABSTRACT

Objective To observe the incidence of spinal cord injury (SCI) following aortic surgery in Fuwai Hospital of Chinese Academy of Medical Sciences, and evaluate the effect of standardized multidisciplinary spinal cord protection strategies, to summarize the experience in the prevention and treatment of SCI at perioperative period of aortic surgery. Methods The clinical data of patients underwent aortic surgery admitted to vascular center of Fuwai Hospital from January 2011 to December 2018 were retrospectively analyzed. The patients receiving traditional spinal cord protection strategies from January 2011 to December 2016 were defined as the control group, while the patients receiving standardized multidisciplinary spinal cord protection strategies from January 2017 to December 2018 were defined as the standardized treatment group. The standardized multidisciplinary treatment included preoperative cerebrospinal fluid drainage (CSFD), respiratory tract management, and maintenance of effective circulation of the lowest venous pressure; at the same time, anticoagulation, glucocorticoid, improve microcirculation, scavenge oxygen free radicals and other adjuvant treatments were started, and nerve function was monitored to prevent complications. The changes in SCI incidence after aortic surgery between the two groups were observed in order to evaluate the effect of standardized multidisciplinary spinal cord protection strategies. Meanwhile, the types of SCI after operation and the safety of CSFD were analyzed. Results During the 8-year period, 7 724 patients underwent aortic surgery at vascular center of Fuwai Hospital, 64 of which suffered from SCI after aortic surgery with total incidence of 0.83%. The onset of SCI was immediate in 39 patients (60.94%) and was delayed in 25 patients (39.06%), more than half of patients were immediate SCI. Of 64 patients with SCI, 52 patients (81.25%) underwent paraplegia and 12 (18.75%) underwent paraparesis. SCI persisted beyond discharge in 38 patients (59.38%) and 25 patients (39.06%) fully or partly recovered form SCI. One patient (1.56%) died. Compared with the control group, the incidence of SCI was decreased significantly after application of standardized multidisciplinary spinal cord protection strategies. The total incidence of SCI after aortic surgery was decreased from 1.06% (52/4 893) to 0.42% (12/2 831), the incidence after aortic arch replacement under deep hypothermic circulatory arrest was decreased from 3.66% (40/1 092) to 1.11% (5/450), and the incidence after thoraco-abdominal aortic replacement was decreased from 9.40% (11/117) to 2.47% (2/81) with statistically significant difference (all P < 0.05). Perioperative CSFD analysis showed that the incidence of CSFD-related complications was low, the overall incidence was 5.45% (3/55), including 1 patient of cerebrospinal fluid leakage, 2 patients of blood cerebrospinal fluid. No serious complications such as hemorrhage and infection of central nervous system occurred. Conclusions The main type of SCI after aortic surgery was immediate, about 39% SCI patients fully or partly recovered. Standardized multidisciplinary spinal cord protection strategies which included preoperative CSFD, reduced incidence of SCI after aortic surgery. The incidence of CSFD-related complications was low, which was safe and effective.

ABSTRACT

Objective: To explore the safety and strategy of thoracic endovascular aortic repair (TEVAR) combining coronary artery bypass grafting (CABG) as one-stop performance in treating the patients with coronary artery disease (CAD) and thoracic aorta disease. Methods: A total of 20 patients received one-stop treatment of TEVAR combining CABG in our hospital from 2009-04 to 2016-01 were retrospectively analyzed. There were 18 male and the mean age of patients was (65.2±8.5, 51-82) years. The performance strategy and peri-operative management were studied. Results: There were 1/20 patient received 2 stents implantation in thoracic aorta and 19 received 1 stent in thoracic aorta those including 1 case with endovascular repair of abdominal aortic aneurysm, 1 with right iliac artery stent implantation and 1 with carotid endarterectomy at meanwhile. The average number of coronary artery bypass branch was (2.4±0.94, 1-4) and 10 (50%) patients received internal mammary artery grafting. The average in-hospital time in all 20 patients was (22.4±11.6, 8-58) days. There were 6 (30%) patients received blood transfusion; 1 (5%) having low cardiac output syndrome received extracorporeal membrane oxygenation (ECMO), then received the second thoracotomy for hemostasis due to excessive pleural effusion; 2 (10%) patients died at 30 days post-operation. 1 patient lost contact and 17 received clinical or telephone follow-up visit at the average of (13.4+13.6, 1-49) months; 2 patients died for cerebral hemorrhage at 12 and 49 months post-operation, the rest 15 had disappeared symptoms and improved quality of life, no operation related death occurred. Conclusion: TEVAR combining CABG as one-stop performance presented good mid-term effect in treating the patients with CAD and thoracic aorta disease; in otherwise, the operative time and risk might be increased by two step performance.

ABSTRACT

Objective To investigate the impact of acute kidney injury ( AKI ) on early and long-term outcome using RIFLEcriteria in patients after acute type A dissection surgery.Methods Between January 2006 and June 2011, 286 cases a-cute type A dissection patients underwent deep hypothermic circulatory arrest surgery were retrospectively analyzed .Using RIFLEcriteria to classfy AKI to risk, injury and failure stages and comparing 30-day mortality, dialysis, ventilation time, ICU stay, hospital stay and cost, and three-year mortality.Multivariate analyses were performed to identify predictors of failure stage.Results AKI was detected in 160 patients(55.9%), and risk 85 cases(29.7%), injury 39 cases(13.6%), failure 36 cases(12.6%).Dialysis rate, ventilation time, ICU stay, cost, and 30-day mortality increased with worsening severity of renal injury, and these was significant increased in failure stage than other groups .There was no association between severity of renal injury and 3-year mortality.Multiple logistic regression showed that malperfusion syndrome ( OR =3.499, 95%CI:1.019-12.013, P=0.047) and WBC(OR=1.121, 95%CI:1.017 -1.237, P=0.022) were independent predictors of renal failure.Conclusion Postoperative mild and morderate acute kidney injury were common in acute type A dissection pa-tients.The severe acute kidney injury had association with poor early outcome .

ABSTRACT

<p><b>OBJECTIVE</b>To assess the safety and efficacy of off-pump technique with normothemia to extend thoracoabdominal aortic aneurysm replacement compared with traditional hypothermic circulatory arrest.</p><p><b>METHODS</b>From January 2004 to December 2013, 128 consecutive patients underwent surgical repair of thoracoabdominal aortic aneurysm (type Crawford Ⅱ) in Fuwai Hospital. The mean age was (37±11) years. The patients included 74 cases (57.8%) with chronic Stanford A dissection, 34 cases (26.6%) with chronic Stanford B dissection, 20 cases (15.6%) with thoracoabdominal aortic true aneurysm. There were 71 patients who underwent hypothermic circulatory arrest surgery (cardiopulmonary bypass (CPB) group) and 57 patients who underwent off-pump surgery with normothermia (off-pump group). The clinic data was compared between the 2 groups using paired t tests and χ(2) test. Kaplan-Meier survival analysis was used for postoperative survival stays.</p><p><b>RESULTS</b>The mean CPB time in CPB group was (251 ±87) minuets and the circulatory arrest time was (45±24) minuets. Spinal cord ischemia time in the two groups was (21±12) minuets and (18±10) minuets (t=5.68, P=0.51). The operation time, ventilator time, length of ICU stay and length of hospital stay of off-pump group were shorter than CPB group ((408±114) minuets vs.(630±156) minuets, t=-7.67, P=0.05; (18±13) hours vs. (113±89) hours, t=-3.86, P=0.00; (4±2) days vs.(10±9) days, t=-4.19, P=0.00; (15±7) days vs.(25±14) days, t=-4.47, P=0.00). The intraoperative blood loss in off-pump group and CPB group was (900±750) ml and (1 400±400) ml (t=-2.23, P=0.04). The mortality was 1.7% and 9.8% in the off-pump group and CPB groups (χ(2)=3.544, P=0.05). The cerebral complication rate in the normal temperature group was 1.7% vs. 22.6% in extracorporeal group (χ(2)=9.35, P<0.05). A total of 113 patients were followed up, with a follow-up rate of 88.2%. Duration of follow-up was (78±54) months. Five patients died during the follow-up period, including 2 who died of cerebral infarction and 3 paraplegia patients who died of infection. Eight patients had phase Ⅱ aortic arch replacement after a mean time of 6 months. The overall postoperative survival rate was 97%, 93% and 87% at 3 years, 5 years and 7 years, respectively.</p><p><b>CONCLUSION</b>Off-pump technique with normothemia was associated with a lower risk of a composite outcome of mortality and major adverse cardiac and cerebrovascular events during repair of extensive thoracoabdominal aortic aneurysm.</p>

ABSTRACT

Objective To explore the impact and value of 11C-MET PET/CT for high-grade glioma in making conformal radiotherapeutic planning compared with MRI.Methods From October 2011 to September 2013,11C-MET PET/CT and MRI were performed in 25 initial glioma cases and 9 recurrent cases.All 34 cases (19 males,15 females) were classified into initial group (n=17),initial surgery group (n=8) and recurrent group (n=9).GTV was outlined using PET/CT images combined with T1 weighted MRI images.Results 11 C-MET PET/CT optimized radiotherapy targets in 22 cases,including 7 initial cases,8 initial surgery cases and 7 recurrent cases.GTV was consistent with the volume of abnormally enhanced region on T1 weighted MRI (VMRI) in 10 initial cases,GTV>VMRI in 5 cases,and GTV<VMRI in 2 cases.GTV<VMR1 in the initial surgery group.GTV was consistent with VMRI in 2 recurrent cases,GTV>VMRI in 2 cases and GTV<VMRI in 4 cases; 1 recurrent case's GTV located largely outside the VMRI.Conclusions There are some differences on locating the lesions of high-grade gliomas between 11C-MET PET/CT and MRI.Using 11CMET PET/CT in sketching radiotherapy target could significantly optimize the high grade glioma's radiotherapeutic planning,which may be more valuable in recurrent or operative cases.
