Aleem K Mirza, J Michael Bacharach
Aortoiliac occlusive disease (AOID) results in varying degrees of pelvic and lower extremity arterial insufficiency. Treatment approach has evolved and endovascular therapies are being successfully reported for high-grade lesion. However, Trans Atlantic Inter-Society Consensus (TASC) D often necessitates open revascularization. Disease limited to the infrarenal segment does not typically affect intestinal perfusion in the absence of visceral aortic or mesenteric vessel involvement. Chronic mesenteric ischemia most commonly occurs due to atherosclerotic disease of two or three of the mesenteric vessels...

OBJECTIVE: Infrainguinal revascularization for disabling claudication (DC) is frequently performed but long term results are still unknown. In this study, we compared clinical outcomes of infrainguinal endovascular (EV) and open interventions for DC following failure of medical management. METHODS: 194 patients with DC (Rutherford category 3) who had open (n=53) or EV (n=141) interventions were grouped as Open-GSV (n=21), Open-Prosthetic (n=32), EV- AB (TASCII A & B) (n=48) and EV-CD (TASCII C & D) (n=93)...

The bone morphogenetic protein (BMP) signaling pathway, including antagonists, functions in lung development and regeneration of tracheal epithelium from basal stem cells. Here, we explore its role in the alveolar region, where type 2 epithelial cells (AT2s) and Pdgfrα+ type 2-associated stromal cells (TASCs) are components of the stem cell niche. We use organoids and in vivo alveolar regrowth after pneumonectomy (PNX) - a process that requires proliferation of AT2s and differentiation into type 1 cells (AT1s)...

BACKGROUND: According to the guidelines, bypass surgery is still the golden standard treatment in patients with femoropopliteal TASC C and D lesions and life-style limiting claudication or CLI. Over the past few decades, endovascular therapy has made great advancements. However, the success rates of surgical and endovascular procedures cannot be directly compared. According to the surgical term "patency", vessel patency can be maintained even in case of a high grade stenosis, whereas according to the endovascular primary patency definition, being binary restenosis, patency is lost from the moment there is a re-narrowing at any location within the treated segment...

INTRODUCTION: For several years, digital subtraction angiography (DSA) was considered the gold standard method for the evaluation of PAD patients. This is an invasive technique and allows a good evaluation of collaterals and the vessel lumen, even in cases with associated calcification. Nevertheless, recent technical development of computed tomography angiography (CTA) has improved its specificity and sensibility, besides the fact that CTA is a fast and non-invasive procedure. OBJECTIVE: To characterize a cohort of lower limb PAD patients and clarify if there are differences among the patients preoperatively evaluated by DSA or CTA...

INTRODUCTION: In the last few years, endovascular approaches have been demonstrating remarkable results on the treatment of aortoiliac TASC D lesions. However, the results remain conflictuous and proper evidence regarding the best treatment option for this group of patients is still lacking. Through this work, we aim to compare patency, cost-effectiveness and quality of life in patients successfully treated by these two approaches. METHODS: Patients with TASC D aorto-iliac disease, from two independent Vascular Surgery Centers, treated either by open surgery and endovascular intervention between 2011- 2017, were retrospectively analyzed and consecutively included (n=59)...

BACKGROUND: Eversion endarterectomy (EE) is a well-described technique for the treatment of extracranial cerebrovascular disease. Longitudinal arteriotomy and closure with patch angioplasty is the standard for infrainguinal arterial occlusive disease in the iliofemoral segment. A potential drawback of this technique is the introduction of exogenous material into the field. We herein describe a technique of transverse femoral arteriotomy with primary closure for treatment of chronic limb ischemia involving the iliofemoral system...

REVIEW
Pankaj P Rao, D V Singh
Traditionally injury care meant definitive repair following surgical exploration. However the outcome is poor because of deranged physiology in severely injured. Damage control surgery (DCS) is abbreviated initial procedure with subsequent correction of physiological imbalance, followed by definite repair. Tactical abbreviated surgical control (TASC) is application of principles of DCS techniques in the tactical environment. TASC is applied because of patient related factors (classic damage control) and limitations due to tactical reasons...

BACKGROUND: Peripheral arterial disease (PAD) is a complex and highly prevalent pathology. It has been estimated that ∼8.5 million people in the United States are affected by PAD, of which 12%-20% are older than age 60. The TransAtlantic Inter-Society Consensus (TASC) guidelines classified aortoiliac atherosclerotic disease based on morphology and level of lesions. TASC II guidelines recommend bilateral surgical bypass to the femoral arteries for TASC II C and D lesions. The aortobifemoral bypass (ABF) has been considered the gold standard in the treatment of aortoiliac occlusive disease (AIOD)...
