ABSTRACT

In recent years, radiotherapy has been widely applied in tumor patients. The short-term and long-term impact on the cardiovascular system has captivated increasing attention from radiologist and cardiologist. Along with higher radiation dose and longer follow-up, the incidence rate of coronary artery disease tends to significantly elevate, especially in patients with breast cancer and lung cancer. With the advancement of radiotherapy technologies, different tumors, different radiation doses and different modes of radiation delivery exert different effects on coronary artery. There are still some disputes about how to prevent, diagnose, evaluate, and treat the high-risk population of coronary artery diseases after radiotherapy. How to optimize the treatment strategy before and after radiotherapy to reduce the incidence of short-term and long-term coronary artery diseases in cancer patients needs further clinical research.

ABSTRACT

Objective:To explorethe the clinical manifestations, treatment and prognosis of anastomotic pseudoaneurysm after renal transplantation caused by infection.Methods:Clinical data of 1 recipient with pseudoaneurysm after renal transplantation due to Pseudomonas aeruginosa infection were retrospectively analysed and combined with a literature review. Results:At Month 2 post-transplantation, the recipient developed right lower abdominal pain, and contrast-enhanced ultrasound examination showed a pseudoaneurysm at the artery anastomosis. Anti-infection and anti-rejection therapy had no obvious effect, and therefore next surgical exploration was performed. A size4.0 cm×3.5cm pseudoaneurysm was found intraoperatively at the graft renal artery anastomosis.After graft was evaluated as having no preservation value, the transplanted kidney and pseudoaneurysm were resected. Bacterial culture indicated Pseudomonas aeruginosa infection.The recipient recovered well and waited for next transplantation. Conclusions:Pseudoaneurysm of transplanted kidney is a very rare complication after renal transplantation, and caused by infection of Pseudomonas aeruginosa is more rarer, It has not been reported in mainland China.This type of recipient has the characteristics of high graft inactivation rate and high mortality rate. Timely surgical resection can effectively prevent the deterioration of disease.

ABSTRACT

Objective@#To explore the clinical application of facial artery perforator flap in repairing medium-size midfacial defects.@*Methods@#Sixteen patients with facial tumors or trauma were admitted in the Affiliated Hospital of Zunyi Medical University, from October 2017 to March 2018. The patients were 41—74 years of age, including 8 males and 8 females. The tissue defects were caused by basal cell carcinoma(BCC, n=10), trauma (n=4), and squamous cell carcinoma (SqCa, n=2). The size of tumor and trauma ranged from 0.3 cm×2 cm to 2 cm×4 cm. Patients with skin tumors undergone extended radical resection, according to the nature of the tumor. Debridement was performed routinely in patients with trauma. Facial artery perforator flap was designed based on the size and shape of defect area. The scar of donor site was as parallel or hidden in the nasolabial groove. The perforator branch of the lateral nasal artery was used as the pivot point, to cover the wound surface without tension. The ipsilateral secondary relay flap pedicled with the perforator of the nasal artery was designed, which was in triangular shape and slightly larger in size than the primary flap. The pedicle was located in the middle of the flap, then the flap was pushed to cover the donor site of primary flap. The postoperative results were evaluated by patients.@*Results@#All primary and secondary relay skin flaps survived. The follow-up period of the first stage was 3—12 months, with an average of 7.5 months. There was no obvious scar, no eyelid eversion or angular deviation, and no recurrence of tumor was observed. The primary and secondary flaps have similar appearance and matched color with normal skin. Ten patients were very satisfied with the surgical outcome, and 6 were satisfied, at the latest follow-up.@*Conclusions@#The facial artery perforator relay skin flap is an alternative method to repair medium facial defect.

ABSTRACT

Objective@#To investigate the clinical effects of free superficial femoral artery femoral triangle perforator flap in the repair of skin and soft tissue defects in extremities.@*Methods@#From January 2016 to November 2017, 14 patients (9 males and 5 females, aged 19 to 54 years) with skin and soft tissue defects in extremities accompanied with tendon and bone exposure were admitted to our unit. The size of skin and soft tissue defects after debridement ranged from 7 cm×3 cm to 10 cm×7 cm. The defects were repaired with free superficial femoral artery femoral triangle perforator flaps, with size ranging from 13.0 cm×2.0 cm to 20.0 cm×4.5 cm. The medial femoral cutaneous nerve was applied to the flap. The perforator flap was grafted onto the medial femoral cutaneous nerve in 6 patients. The donor sites were sutured directly. The survival of flaps and the follow-up of patients were observed.@*Results@#All flaps of 14 patients survived successfully. The recipient sites and donor sites were healed completely in 13 patients, and 1 patient with partial skin necrosis at the edge of flap was healed after treatment. All patients were followed up for 6 months to 1 year after the operation. The flaps were in good shape, with nearly normal color and soft texture and no cicatrix contracture deformity. The flaps recovered protective sense in 6 patients who had medial femoral cutaneous nerve grafting, and the sensory recovery of the flap was slightly worse in the remaining 8 patients. There was no significant complications on the appearance and walking of the donor thigh in 14 patients, only a linear scar was left on the inner thigh, and no numbness was felt in the donor sites of patients.@*Conclusions@#The free superficial femoral artery femoral triangle perforator flap is an ideal therapy for repairing skin and soft tissue defects in extremities.

ABSTRACT

Objective@#To provide clinical guidance for clinical selection, through retrospective analysis for the advantages and disadvantages of superficial iliac circumflex artery and lateral circumflex femoral artery perforator flap in wound repair.@*Methods@#From July 2016 to January 2018, 89 cases were repaired with superficial iliac circumflex artery or lateral femoral circumflex artery perforator flap, including 32 cases of superficial circumflex iliac artery perforator flap, 18 cases of upper limb, 6 cases of face and neck, and 8 cases of lower extremity. There were 52 cases of lateral circumflex femoral artery perforator flap, 21 cases of upper limb, 2 cases of neck, 3 cases of trunk, 26 cases of lower extremity, 5 cases of superficial circumflex iliac artery perforator flap combined with lateral femoral circumflex artery perforator flap, 3 cases of upper limb and 2 cases of lower extremity. The perforators of superficial circumflex iliac artery or (and) lateral circumflex femoral artery were detected by portable Doppler flow detector before operation. According to the wound size, the superficial circumflex artery perforator flap or (and) lateral circumflex femoral artery perforator flap was or (were) designed and resected. End-to-end or end-to-side anastomosis was performed in vascular pedicle. In the combined resection group, the end-to-end or end-to-side anastomosis of the perforator of the lateral circumflex thigh artery was performed, and the pedicled part of the superficial circumflex iliac artery was used for supercharging.@*Results@#All the flaps survived successfully except one combined flap had tip necrosis on the superficial iliac circumflex artery perforator flap part. and healed after 2 weeks of dressing change. Venous crisis occurred on the first day after operation of superficial iliac circumflex artery perforator flap in 1 case.10 cases of lateral femoral circumflex artery perforator flap were slightly bloated and 3 cases returned to hospital for secondary thinning. All the flaps were soft in texture, satisfactory in shape and function, and numbed in the small area of the donor region of the perforator flap of lateral femoral circumflex artery in the early stage. All the patients had no severe complications after follow-up.@*Conclusions@#The perforator flap of superficial iliac circumflex artery and lateral femoral circumflex artery are ideal donor areas for wound repair. The perforator flap of superficial iliac circumflex artery is preferred for small area wound, hand wound and small bone defect. Lateral circumflex femoral perforator flap is suitable for all trunk and limbs with large or complex wounds.

ABSTRACT

Objective@#To evaluate the efficacy of paclitaxel-coated balloon for de novo coronary lesions with diameters ≥ 2.8 mm.@*Methods@#This prospective study included 215 consecutive patients with 238 de novo lesions, who received paclitaxel-coated balloon angioplasty in Beijing Hospital from May 2014 to June 2016. According to the reference vessel diameter, the patients were divided into large vessel disease (LVD) group (reference vessel diameter≥2.8 mm, 85 patients and 90 lesions) and small vessel disease (SVD) group (reference vessel diameter<2.8 mm, 130 patients and 148 lesions). Clinical characteristics, interventional procedures and major adverse cardiovascular events (includingall-cause mortality, non-fatal myocardial infarction and target lesion revascularization) after procedure were compared between the 2 groups.@*Results@#(1)Patients in LVD group were younger than SVD group ((60.1±11.1) years old vs. (65.0±10.6) years old, P<0.01), and less patients had diabetes (24.7% (21/85) vs. 43.1%(56/130), P<0.01).(2)Prevalence of three-vessel disease (35.5%(30/85) vs. 53.6%(67/130), P<0.05) and complex lesions (type B2/C,34.4% (31/90) vs. 50.0%(74/148), P<0.05) were significantly lower in LVD group than in SVD group.(3) During pre-dilation, the rate with plain balloons use was significantly higher in SVD group than in LVD group(76.4%(113/148) vs. 58.9%(53/90), P<0.01), while the proportion of additional use of non-compliant balloons was significantly higher in LVD groupthan in SVD group(20.0% (18/90) vs. 3.4% (5/148) , P<0.01). The ratio of paclitaxel-coated balloon diameter/RVD was significantly lower (0.87±0.12 vs. 0.96±0.15, P<0.01) and the duration of dilationwas significantly shorter ((41.5±9.5) seconds vs. (45.1±9.1) seconds, P<0.01) in LVD group than those in SVD group. Each group had 1 failure case that was bailout stented with drug-eluting stents. The success rate of paclitaxel-coated balloon treatment was similar in LVD group and SVD group (98.9% (89/90) vs. 99.3%(147/148), P>0.05).(4) At the fourth day of procedure, there was 1 acute myocardial infarction requiring emergent target lesion revascularization in SVD group. No major adverse cardiovascular event was observed in LVD group during hospitalization. Forty-two patients with 53 lesions, including 27 LVD lesions and 26 SVD lesions,underwent coronary angiography at (9.4±4.6) months after paclitaxel-coated balloon intervention. The quantitative coronary angiography analysis showed that minimal lumen diameter significantlyincreased during follow-up than that of post-procedurein SVD group ((1.71±0.36)mm vs. (1.52±0.30)mm, P<0.05) , while in LVD group the minimal lumen diameter was similar between during follow-up and post-procedure ((2.35±0.48)mm vs. (2.19±0.34)mm, P>0.05). Major adverse cardiovascular event rate was 0 in LVD group and 2.3%(3/130) in SVD group (P>0.05) during follow up. No death was observed in this patient cohort.@*Conclusion@#Treatment with paclitaxel-coated balloon for de novo coronary lesions with diameters≥2.8 mm is safe and effective.

ABSTRACT

Objective To observe the changes of serum soluble CD40 ligand (sCD40L) and fibrinogen in acute myocardial infarction (AMI) patients and to investigate the clinical predictive value of increased serum sCD40L and fibrinogen. Methods Serum sCD40L level of 60 AMI patients was determined by enzyme-linked im-munosorbent assay (ELISA). Plasma level of fibrinogen was measured. The patients were followed up for 2 years af-ter discharge from the hospital and were observed for cardiovascular event. Results AMI patients had higher sCD40L and fibrinogen levels than those of controls [(15.36±7.32) μg/L vs. (5.79±2.78) μg/L, (4.60±1.37)g/L vs. (3.03±0.82) g/L,P<0.001] ,which were significantly higher in the patients experiencing cardio-vascular event than those without cardiovascular event [(18.14±6.34) μg/L vs. (14.38±6.67) μg/L and (4.97±1.33)g/L vs. (4.20±1.24} g/L] (P<0.05). The patients with sCD40L≥14.5 μg/L or fibrinogen≥ 4.4 g/L experienced increased risk of adverse cardiovascular events (P<0.05). In AMI patients, sCD40L level was significantly higher in patients with diabetes than in nondiabetics [(18.38±6.71) μg/L vs. (14.46±6.48) μg/L, P<0.05)]. Fibrinogen level was related to sCD40L (r=0.27, P<0.05) and LVEF(r=-0.319, P<0.05). Conclusion Increased sCD40L and fibrinogen levels,which maybe related to the pathogenesis of AMI,can be found in AMI patients and can indicate an independent increased risk of major adverse cardiovascular events. Diabetes is independently associated with elevated sCD40L level in AMI patients.
