Type B aortic dissection is a life-threatening aortic disease.With the development of clinical classification and diagnostic method,the mortality of type B aortic dissection has been greatly decreased.In respect of treatment,endovascular repair due to minimally invasive advantages become the first choice for the treatment of complicated type B aortic dissection.For non-complicated type B aortic dissection,endovascular repair also gradually replace drug treatment,and showed good efficacy.Open surgery is only available for patients who ate not suitable for endovascular repair or repair failure or patients with connective tissue disease.

Objective:To evaluate the efficacy and safety of physician-modified fenestration TEVAR for treating type B aortic dissection with unhealthy or short anchoring zone.Methods:Clinical data of patients with type B aortic dissection who received TEVAR for left subclavian artery fenesration from May 2016 to Dec 2018 were analyzed prospectively.Results:The technical success rate was 93.2%. One case was converted into chimney stenting. One case suffered type Ⅰendoleak. One case had type Ⅲ endoleak. There were no deaths or neurological complications during the perioperative period, and the mean hospital stay was 9.2 (5-26) days. The median follow-up time was 30 (12-42) months. One case developed type Ⅰ endoleak during follow-up. No retrograde dissection occurred and all LSA stents remained patent.Conclusion:Physician-modified fenestration TEVAR is safe and effective for the treatment of type B aortic dissection with unhealthy or short anchoring zone.

OBJECTIVETo evaluate the clinical efficacy of interventional therapy in the treatment of hepatocellular carcinoma (HCC).

METHODSThirty-three patients with HCC were synthetically treated by systematic measures. Among them, percutaneous port-catheter system (PCS) implantation via the femoral artery was performed in 21 cases. Patients with haemorrhage were treated with prothrombin complex concentrate and fibroraas, and patients with hepatic encephalopathy by branched-chain amino acids and arginine.

RESULTSAll indwelling catheters of PCS were patent and no catheter tip dislocations were observed. Of 33 patients with advanced HCC, the mean survival rate was 20.1 months and 12 (36%) patients survived more than 2 years.

CONCLUSIONPatients with advanced HCC were treated by synthetic measures. Survival was prolonged, quality of life was improved significantly, and the effectiveness of interventional therapy was further improved.

Objective To evaluate fenestrated thoracic endovascular aortic repair (f-TEVAR) using fenestrated stent graft on table in zone 0 and zone 1 for aortic arch diseases.Methods 13 patients undergoing f-TEVAR by using physician modified fenestrated stent grafts (PMSGs) on table in zone 0 and zone 1 for aortic arch diseases between Nov 2015 and Mar 2018 were retrospectively reviewed.Results The median age was 59 years(range,33-81 years).PMSGs were deployed from Z0 in 5 patients and Z1 in remaining 8 patients.All but 3 patients underwent elective procedure.The technical success rate was 92.3％.Overall mortality was 7.7％ (1/13).There were no perioperative neurologic complications and paraplegia.One patient suffering from acute left leg ischemia and renal failure recovered after openembolectomy and dialysis.Median length of stay was 9.0 days (range,4-35 days).12 patients were survival at a median follow-up of 11.5 months (range,1.0-19.0 months).Retrograde dissection occurred in one patient and resolved after open repair.During follow up,all target vessels remained patent,with no fenestration-related type Ⅰ or Ⅲ endoleaks.Conclusions f-TEVAR using modified fenestrated stent grafts on table in Z0 and Z1 is feasible for the treatment of aortic arch diseases.

Objective To evaluate fenestrated endovascular aortic repair (FEVAR) using physician-modified stent-grafts (PMSGs) for thoraco-abdominal aortic lesions.Methods Seven cases of thoraco-abdominal aortic lesions (1 type Ⅲ thoraco-abdominal aortic aneurysm,1 type Ⅳ thoraco-abdominal aortic aneurysm,4 chronic thoraco-abdominal aortic dissection and 1 type Ⅰ endoleak after EVAR due to abdominal aortic aneurysm) were treated with FEVAR from Nov 2016 to Nov 2017.Results FEVAR was performed successfully in all cases.Type Ⅱ and Ⅲ endoleak occurred in 4 cases.One died of acute myocardial infarction 2 days postoperatively.Renal dysfunction deterioration occurred in one case of chronic dissection and improved after the medical treatment.Renal subcapsular hematoma was found in 2 cases postoperatively,and resolved after conservative therapy.Mean follow-up period was 7.2 months,target vessel patency was identified in 5 of the 6 cases.Conclusions FEVAR using PMSGs is a viable alternative to treat thoraco-abdominal aortic lesions.

Objective: To evaluate the short-term efficacy of branched TEVAR in the treatment of complex aortic arch lesions. Methods: The clinical data of 18 patients with aortic lesions requiring reconstruction of the left subclavian artery who were treated with branch TEVAR technology in Tianjin Medical University General Hospital from Apr 2016 to Dec 2018 were analyzed retrospectively. Results: There were 16 cases using Castor external branch stent implantation and 2 cases of self-made internal branch stent. The success rate of device release was 100%, the success rate of operation was 100%, and there were no intraoperative deaths. Postoperative complications occurred in 2 cases: one proximal stent tear dissection required open surgery, one died of massive myocardial infarction.Seventeen patients were followed up for 1-8 months. CTA examination in 16 patients 30 days after surgery, found 1 patient with type Ⅲ endoleak. CTA examination done in 8 patients 6 months after surgery found distal occlusion of left subclavian artery stent in 1 patient necess itating distal stent implantation. Conclusion The branch TEVAR technique is effective method to reconstruct the arch branched artery.
