RATIONALE: Placenta accreta is the main cause of severe obstetric postpartum hemorrhage (PPH) and hysterectomy. Several hemostatic techniques have been performed in patients with placenta accreta to prevent PPH and reserve fertility. Abdominal aorta and pelvic arteries balloon occlusion are the only techniques which could be performed before cesarean section (CS) in patients who want to keep the fetus and reserve fertility. However, abdominal aorta and pelvic arteries balloon occlusion might lead to severe complications such as formation and rupture of pseudoaneurysm, angiorrhexis, etc...

Iatrogenic acute dissection of the ascending aorta is a serious but rare complication of cardiac catheterization and percutaneous coronary intervention (PCI). Although treatment of ascending aortic dissection may require surgical repair, stenting at the origin of the dissection area may be sufficient in aortocoronary dissection (AD) following PCI. Described is the case of a 64-year-old female patient who was treated with PCI for a critical lesion of the right coronary artery (RCA). Immediate stenting at the source of the dissection was sufficient to repair the RCA lesions and successfully seal the site of retrograde propagation of the dissection...

Pseudoaneurysm in Salmonella infection is a rare complication of lupus. We describe a 51-year-old woman with lupus who suffered from swelling and painful sensation of right lower limbs. The Doppler ultrasound study revealed a large pseudoaneurysm of right superficial femoral artery and the tissue culture was Salmonella group D. Surgical repair with stent grafting was performed successfully. This vascular complication with Salmonella infection has not been previously described in lupus.

OBJECTIVE/BACKGROUND: A meta-analysis of recently published randomised controlled trials (RCTs) was performed to evaluate the safety of carotid artery stenting (CAS) versus carotid endarterectomy (CEA) for asymptomatic carotid stenosis with average risk. METHODS: The MEDLINE, Embase, and Cochrane Library databases were systematically searched for RCTs that compared CAS with CEA for asymptomatic carotid stenosis. These publications reported clinical outcomes after revascularisation in patients with asymptomatic carotid stenosis during their primary intervention...

BACKGROUND: We hypothesized the inflammatory markers (IM) could be independent predictors of carotid stenosis progression (CSP) after carotid artery stenting (CAS). METHODS: Between 2010 and 2012, 122 patients undergoing cervicocranial revascularization in our hospital were prospectively recruited. Patients undergoing revascularizations other than CAS were excluded. Carotid duplex ultrasonography was performed before and at 1 week, 6 months (6M), 1 year, and 2 years after CAS...

Endovascular aortic repair (EVAR) has revolutionized the treatment of infrarenal abdominal aortic aneurysm (AAA), with consistently low reported perioperative morbidity and mortality. Universal applicability of EVAR to treat AAA is hindered by several specific anatomic constraints, however, and many patients cannot be treated with commercially available stent grafts within the device specific instructions for use. Treatment of these complex pararenal aneurysms is increasingly accomplished by extension of EVAR into the visceral segment of the abdominal aorta with branches or fenestrations that allow perfusion of the visceral and renal arteries...

BACKGROUND AND OBJECTIVES: Neurologic intolerance (NI) is defined as the occurrence of neurological symptoms during carotid artery stenting (CAS). Because NI is inevitable problem, it may be helpful to anticipate its occurrence. So, we studied factors associated with NI during proximal protected CAS. METHODS: We retrospectively analyzed all consecutive patients underwent proximal protected CAS from August 2012 to January 2017. RESULTS: We included total 123 patients (109 males, 72±8 years old)...

Femoropopliteal (FP) artery-in stent restenosis (ISR) is a daunting management problem that we continue to face. FP artery-ISR rates after primary stent implantation are relatively high. Although repeat FP artery-ISR and the need for additional interventions remain all too common, little consensus exists regarding the best treatment algorithm. In this article, we review the limitations of the currently used devices for the endovascular treatment of FP artery-ISR and discuss which strategies are the most effective and safe...

Bare-metal stents (BMS) and paclitaxel-eluting stent (PES) are frequently used in medicine for the treatment of coronary heart disease, with millions of patients treated worldwide. The protein-protein interactions (PPI) were adopted to construct the networks. The M-module algorithm was used to identify multiple differential modules. Gene Ontology enrichment and pathway enrichment analysis were performed to analyze characteristics of modules. With the PPI and microarray data, two differential co-expressed networks were constructed, module 1 indicating PES and module 2 indicating BMS, with the same genes but different edges...
