Intra-Sac Injection of Thrombin During Endovascular Aneurysm Repair to Remedy Type II Endoleak and Promote Sac Shrinkage.

Purpose: To evaluate the safety and effectiveness of intra-sac thrombin injection to remedy type II endoleaks (T2ELs) during endovascular aneurysm repair (EVAR).

Materials And Methods: 224 cases abdominal aortic aneurysm (AAA) were treated with EVAR. For the 52 cases of intra-operative type II endoleaks and 8 cases of ruptured AAAs, after the grafts were deployed, thrombin was injected into the aneurysm sac through a preset catheter.

Comparison of complete multi-level vs. iliac-only revascularization for concomitant iliac and superficial femoral artery occlusive disease.

Objective: The aim of this study is to compare the efficacy and safety of complete multi-level vs. iliac-only revascularization for the treatment of concomitant iliac and superficial femoral artery (SFA) occlusive disease.

Methods: A total of 139 consecutive adult patients with severe stenosis and occlusive iliac and SFA disease with Rutherford categories 2-5 underwent multi-level ( = 71) and iliac-only ( = 68) revascularization at the Department of Intervention Vascular Surgery, Peking University Third Hospital, and Aerospace Center Hospital, between March 2015 and June 2017.

Construction of Transjugular Intrahepatic Portosystemic Shunt: Bare Metal Stent/Stent-graft Combination versus Single Stent-graft, a Prospective Randomized Controlled Study with Long-term Patency and Clinical Analysis.

Background: Balanced adjustment of the portal vein shunt volume during a transjugular intrahepatic portosystemic shunt (TIPS) is critical for maintaining liver perfusion and decreasing the incidence of liver insufficiency. A stent-graft is proved to be superior to a bare metal stent (BMS) for the construction of a TIPS. However, the clinical results of the combination application of stents and stent-grafts have not been determined.

[Percutaneous transluminal angioplasty versus stent implantation for treatment of femoral and popliteal artery lesion resulted from arteriosclerosis obliterans].

Objective: To study the clinical effects of percutaneous transluminal angioplasty (PTA) versus stent implantation (ST) after PTA for the treatment of femoral and popliteal artery lesion resulted from arteriosclerosis obliterans.

Methods: One hundred and three patients (119 limbs) treated for femoral and popliteal artery lesion resulted from arteriosclerosis obliterans for ten years were reviewed, of whom 60 limbs were treated by PTA and the other 47 by PTA combined with stent implantation.

Results: Among the 60 limbs of the PTA group, there were 22 limbs involved only in femoral and popliteal artery; 13 limbs combined with iliac artery lesion; 17 limbs combined with infrapopliteal artery lesion; 8 limbs combined with iliac and infrapopliteal artery lesion.

[Relative factors of type II endoleak after endovascular aneurysm repair].

Objective: To study the relative factors of type II endoleak after endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms.

Methods: Twenty-eight cases of abdominal aortic aneurysms treated by EVAR were retrospectively analyzed. The characteristics of the inferior mesentery arteries (IMA), the arc Riolan and the lumbar arteries of the cases with or without type II endoleak were analyzed.

[Comparison of the clinical efficacy of endovascular reconstruction versus bypass surgery for transatlantic inter-society consensus II C/D femoropopliteal artery lesion resulted from arteriosclerosis obliterans].

Objective: To study the clinical effects of endovascular reconstruction versus bypass surgery for TASC II(trans-atlantic inter-society consensus II) C/D femoropopliteal artery lesion resulted from arteriosclerosis obliterans.

Methods: One hundred and three patients(119 limbs)accepted bypass surgery or endovascular therapy for TASCII C/D femoropopliteal artery lesion between January 2002 and December 2012 at our institution were retrospectively assessed.All the patients were diagnosed with arteriosclerosis obliterins, and all their Rutherford classifications were from 2 to 5 degrees.

Isolated superior mesenteric artery dissection in China.

Objective: This study investigated the status of isolated superior mesenteric artery (SMA) dissection in the most populous country, China.

Methods: The Chinese-language literature published before December 2014 was reviewed. All case reports and series were included.

[Related factors of hemodynamic damage after carotid artery stenting].

Objective: To analyze correlation factors of hemodynamic damage after carotid artery stenting.

Methods: In this study, 66 cases (71 lesions) who undertook carotid artery stenting were collected and the correlation factors of hemodynamic damage were analyzed.

Results: Hemodynamic damage emerged in 23 cases (32.

Detection of Two Drug-Resistance Mutants of the Cytomegalovirus by High-Resolution Melting Analysis.

Background: Human cytomegalovirus (CMV) is an opportunistic pathogen that can be treated with ganciclovir. Mutations in the UL97 gene of CMV render the virus ganciclovir resistance. These include H520Q and C603W mutations, against which we developed a novel genotyping assay for their identification.

[Technological modification of transjugular intrahepatic portosystemic shunt: the precise covering of parenchymal shunt with stent-graft].

Objective: To introduce the technological modification of stents placement with combined naked self-expanding stent and stent-graft for the construction of portosystemic shunt during transjugular intrahepatic portosystemic shunt (TIPS).

Methods: In the study, 17 patients who suffered from upper digestive tract hemorrhage due to portal hypertension post liver cirrhosis underwent modified TIPS. The shunts were constructed with stepwise placement of naked self-expanding stent and a stent-graft other than stent-graft only for the purpose of precisely covering the parenchymal segment of the shunt and the active control of portosystemic gradient (PSG).

Vasodilator and endovascular therapy for isolated superior mesenteric artery dissection.

Objective: We report our experience in the treatment of isolated superior mesenteric artery dissection and review the clinical and imaging features reported in the literature.

Methods: A retrospective study was conducted of 18 consecutive patients with isolated superior mesenteric artery dissection who presented at the Peking University Third Hospital between September 2008 and May 2012. Their clinical characteristics, including age, sex, medical history, risk factors, symptoms, diagnostic imaging modality, and treatment, were analyzed.
