Inhibition of nitric oxide but not prostacyclin prevents poststenotic dilatation in rabbit femoral artery. (1/2966)

BACKGROUND: Poststenotic dilatation (PSD) occurs in a low-pressure region where recirculation eddies oscillate in size during the cardiac cycle. NO may be an important mediator of PSD. METHODS AND RESULTS: Femoral arteries of 7 adult male New Zealand White rabbits were stenosed bilaterally to achieve a diameter reduction of 70. 9+/-6.7% (n=14). At the time of stenosis, the adventitia of one of the arteries was coated with 1 mmol/L of NG-nitro-L-arginine methyl ester (L-NAME) in 22% (wt/vol) Pluronic gel, while the contralateral vessel was coated with gel without L-NAME. In stenosed femoral arteries that were treated with gel without L-NAME, a maximum PSD of 30.99+/-7.92% (n=7) was observed in polymer casts at 3 days relative to the mean proximal diameter of 1.57+/-0.25 mm at a position 12 mm upstream of each stenosis. In contrast, the vessels treated with L-NAME exhibited a maximum PSD of only 7.16+/-8.81% (n=7) relative to the mean proximal diameter of 1.55+/-0.16 mm. L-NAME caused a 76. 9% reduction (P<0.001, n=7) of PSD. Similarly, NG-monomethyl-L-arginine 1 mmol/L and NG-nitro-L-arginine 10 micromol/L attenuated PSD by 57.5% (P<0.001, n=6) and 63.9% (P<0.05, n=6), respectively. Indomethacin 10 micromol/L caused no reduction in PSD. Arterial rings obtained from the poststenotic region were more sensitive and responsive to acetylcholine than those obtained proximal to the stenosis. CONCLUSIONS: NO, but not prostacyclin, is a major mediator of PSD.  (+info)

Isolated femoropopliteal bypass graft for limb salvage after failed tibial reconstruction: a viable alternative to amputation. (2/2966)

PURPOSE: Femoropopliteal bypass grafting procedures performed to isolated popliteal arteries after failure of a previous tibial reconstruction were studied. The results were compared with those of a study of primary isolated femoropopliteal bypass grafts (IFPBs). METHODS: IFPBs were only constructed if the uninvolved or patent popliteal segment measured at least 7 cm in length and had at least one major collateral supplying the calf. When IFPB was performed for ischemic lesions, these lesions were usually limited to the digits or small portions of the foot. Forty-seven polytetrafluoroethylene grafts and three autogenous reversed saphenous vein grafts were used. RESULTS: Ankle brachial pressure index (ABI) increased after bypass grafting by a mean of 0.46. Three-year primary life table patency and limb-salvage rates for primary IFPBs were 73% and 86%, respectively. All eight IFPBs performed after failed tibial bypass grafts remained patent for 2 to 44 months, with patients having viable, healed feet. CONCLUSION: In the presence of a suitable popliteal artery and limited tissue necrosis, IFPB can have acceptable patency and limb-salvage rates, even when a polytetrafluoroethylene graft is used. Secondary IFPB can be used to achieve limb salvage after failed tibial bypass grafting.  (+info)

Superficial femoral eversion endarterectomy combined with a vein segment as a composite artery-vein bypass graft for infrainguinal arterial reconstruction. (3/2966)

OBJECTIVE: The purpose of this study was to determine the results of composite artery-vein bypass grafting for infrainguinal arterial reconstruction. METHODS: This study was designed as a retrospective case series in two tertiary referral centers. Forty-eight of 51 patients underwent the procedure of interest for the treatment of ischemic skin lesions (n = 42), rest pain (n = 3), disabling claudication (n = 1), and infected prosthesis (n = 2). The intervention used was infrainguinal composite artery-vein bypass grafting to popliteal (n = 18) and infrapopliteal (n = 30) arteries, with an occluded segment of the superficial femoral artery prepared with eversion endarterectomy and an autogenous vein conduit harvested from greater saphenous veins (n = 43), arm veins (n = 3), and lesser saphenous veins (n = 2). The main outcome measures, primary graft patency rates, foot salvage rates, and patient survival rates, were described by means of the life-table method for a mean follow-up time of 15.5 months. RESULTS: The cumulative loss during the follow-up period was 6% and 24% at 6 and 12 months, respectively. The primary graft patency rates, the foot salvage rates, and the patient survival rates for patients with popliteal grafts were 60.0% +/- 9.07%, 75.7% +/- 9.18%, and 93.5% +/- 6.03%, respectively, at 1 month; 53.7% +/- 11.85%, 68.9% +/- 12.47%, and 85. 0% +/- 9.92% at 1 year; and 46.7% +/- 18.19%, 68.9% +/- 20.54%, and 53.1% +/- 17.15% at 5 years. For infrapopliteal grafts, the corresponding estimates were 72.4% +/- 7.06%, 72.9% +/- 6.99%, and 92.7% +/- 4.79% at 1 month; 55.6% +/- 10.70%, 55.4% +/- 10.07%, and 77.9% +/- 9.02% at 1 year; and 33.6% +/- 22.36%, 55.4% +/- 30.20%, and 20.8% +/- 9.89% at 5 years. CONCLUSION: The composite artery-vein bypass graft is a useful autogenous alternative for infrainguinal arterial reconstruction when a vein of the required quality is not available or when the procedure needs to be confined to the affected limb.  (+info)

Plaque area increase and vascular remodeling contribute to lumen area change after percutaneous transluminal angioplasty of the femoropopliteal artery: an intravascular ultrasound study. (4/2966)

OBJECTIVE: The aim of the study was to assess the change in lumen area (LA), plaque area (PLA), and vessel area (VA) after percutaneous transluminal angioplasty (PTA) of the femoropopliteal artery. METHODS: This was a prospective study. Twenty patients were studied with intravascular ultrasound (IVUS) immediately after PTA and at follow-up examination. Multiple corresponding IVUS cross-sections were analyzed at the segments that were dilated by PTA (ie, treated sites; n = 168), including the most stenotic site (n = 20) and the nondilated segments (ie, reference sites; n = 77). RESULTS: At follow-up examination, both the PLA increase (13%) and the VA decrease (9%) resulted in a significant LA decrease (43%) at the most stenotic sites (P =.001). At the treated sites, the LA decrease (15%) was smaller and was caused by the PLA increase (15%). At the reference sites, the PLA increase (15%) and the VA increase (6%) resulted in a slight LA decrease (3%). An analysis of the IVUS cross-sections that were grouped according to LA change (difference >/=10%) revealed a similar PLA increase in all the groups: the type of vascular remodeling (VA decrease, no change, or increase) determined the LA change. At the treated sites, the LA change and the VA change correlated closely (r = 0.77, P <.001). At the treated sites, significantly more PLA increase was seen in the IVUS cross-sections that showed hard lesion or media rupture (P <.05). No relationship was found between the presence of dissection and the quantitative changes. CONCLUSION: At the most stenotic sites, lumen narrowing was caused by plaque increase and vessel shrinkage. Both the treated sites and the reference sites showed a significant PLA increase: the type of vascular remodeling determined the LA change at follow-up examination. The extent of the PLA increase was significantly larger in the IVUS cross-sections that showed hard lesion or media rupture.  (+info)

The diameter of the common femoral artery in healthy human: influence of sex, age, and body size. (5/2966)

PURPOSE: To determine the relevance of dilatations of the common femoral artery (CFA), knowledge of the normal CFA diameter is essential. The diameter of the CFA in healthy male and female subjects of different ages was investigated. METHODS: The diameter of the CFA was measured in 122 healthy volunteers (59 male, 63 female; 8 to 81 years of age) with echo-tracking B-mode ultrasound scan. The influence of age, sex, height, weight, body surface area (BSA), and systolic blood pressure was analyzed by means of a multiple regression model. RESULTS: The CFA increased steadily in diameter throughout life. From 25 years onwards, the diameter was larger in men than in women. Significant correlations were found between the CFA diameter and weight (r = 0.58 and r = 0.57 in male and female subjects, respectively; P <.0001), height (r = 0.49 and r = 0.54 in male and female subjects, respectively; P <.0001), and BSA (r = 0.60 and r = 0.62 in male and female subjects, respectively; P <.0001). Age and BSA were used to create a model for prediction of the CFA diameter (r = 0.71 and r = 0.77 in male and female subjects, respectively; P <.0001). CONCLUSION: The diameter of the CFA increases with age, initially during growth but also in adults. This is related to age, body size, and sex male subjects have larger arteries than female subjects. It is now possible to predict the normal CFA diameter, and nomograms that may be used in the study of aneurysmal disease are presented.  (+info)

Use of high-intensity focused ultrasound to control bleeding. (6/2966)

OBJECTIVE: High-intensity focused ultrasound (HIFU) has been shown to be effective in controlling hemorrhage from punctures in blood vessels. The objective of the current study was to investigate the capability of HIFU to stop bleeding after a more severe type of vascular injury, namely longitudinal incisions of arteries and veins. METHODS: The superficial femoral arteries, common femoral arteries, carotid arteries, and jugular veins of four anesthetized pigs were exposed surgically. A longitudinal incision, 2 to 8 mm in length, was produced in the vessel. HIFU treatment was applied within 5 seconds of the onset of the bleeding. The HIFU probe consisted of a high-power, 3.5-MHz, piezoelectric transducer with an ellipsoidal focal spot that was 1 mm in cross section and 9 mm in axial dimension. The entire incision area was scanned with the HIFU beam at a rate of 15 to 25 times/second and a linear displacement of 5 to 10 mm. A total of 76 incisions and HIFU treatments were performed. RESULTS: Control of bleeding (major hemosatsis) was achieved in all 76 treatments, with complete hemostasis achieved in 69 treatments (91%). The average treatment times of major and complete hemostasis were 17 and 25 seconds, respectively. After the treatment, 74% of the vessels in which complete hemostasis was achieved were patent with distal blood flow and 26% were occluded. The HIFU-treated vessels showed a consistent coagulation of the adventitia surrounding the vessels, with a remarkably localized injury to the vessel wall. Extensive fibrin deposition at the treatment site was observed. CONCLUSION: HIFU may provide a useful method of achieving hemostasis for arteries and veins in a variety of clinical applications.  (+info)

Disruption of skin perfusion following longitudinal groin incision for infrainguinal bypass surgery. (7/2966)

OBJECTIVE: The objective of our study was to investigate whether such an incision results in a reduction in blood flow, and therefore haemoglobin oxygen saturation, across the wound. DESIGN: Microvascular oxygenation was measured with lightguide spectrophotometry in 21 patients undergoing femoropopliteal or femorodistal bypass procedures. A series of measurements were made in the groin, medial and lateral to the surface marking of the femoral artery. The mean oxygen saturation on each side was calculated, and the contra-lateral groin was used as a control. The measurements were repeated at 2 and 7 days postop. RESULTS: Oxygen saturation in the skin of the operated groins was increased significantly from baseline at 2 days postop (f = 25.80, p < 0.001) and had begun to return to normal by day 7. The rise was more marked on the lateral side of the wound than on the medial (f = 12.32, p < 0.001). There was no such difference in the control groins. All wounds healed at 10 days. CONCLUSIONS: These results show a significant difference in skin oxygenation between the lateral and medial sides of the groin following longitudinal incision. This may contribute to the relatively high incidence of postoperative infection in these wounds.  (+info)

Outcome of the first 100 femoropopliteal angioplasties performed in the operating theatre. (8/2966)

OBJECTIVES: To examine the factors influencing outcome and restenosis in an initial series of 100 infrainguinal angioplasties. DESIGN: Prospective study of angioplasties of the superficial femoral and popliteal arteries performed over a 42-month period. MATERIALS AND METHODS: One hundred consecutive angioplasties in 96 patients performed in the operating theatre between January 1993 and June 1996 were followed prospectively with clinical, ABI, and duplex assessment. Forty-four procedures were for disabling claudication and 56 for critical ischaemia. Stents were deployed in 30 limbs. RESULTS: Angioplasty was successful in 84 of 100 limbs. Cumulative patency of the entire group at 3, 6, 12 and 18 months was 78%, 60%, 53%, and 49% respectively, while excluding initial failures, gave patencies of 95%, 69%, 63%, and 58%, respectively. Claudicants with a 1-year patency of 64% did significantly better than patients with critical ischaemia (44% p < 0.05). Angioplasties performed during the initial 21 months had a 1-year patency of 42%, while those performed in the final 21 months had a 74% patency (p = N.S.). The patency for stented arteries was 66% vs. 49% for angioplasty alone (p = N.S.). The 2-year limb salvage rate was 91% in patents with critical ischaemia. Forty-six per cent of restenoses were asymptomatic. CONCLUSIONS: The results suggest that while angioplasty is useful in treating infrainguinal arterial disease, there is a learning curve, resulting in a high restenosis rate for occlusive and multilevel disease, while concomitant placement of stents may be beneficial.  (+info)

The lateral circumflex femoral artery (lateral femoral circumflex artery, external circumflex artery) is an artery in the upper thigh. The lateral femoral circumflex artery arises from the lateral side of the profunda femoris artery, passes horizontally between the divisions of the femoral nerve, and behind the sartorius and rectus femoris, and divides into ascending, transverse, and descending branches. The lateral femoral circumflex artery may occasionally arise directly from the femoral artery. The artery usually courses anterior to the femoral neck and in between the branches of femoral nerve. A rare variant where the artery passes posterior to the femoral nerve has also been reported which is of great significance to the surgeon. The lateral circumflex femoral artery has three branches: The ascending branch of lateral circumflex femoral artery passes upward, beneath the tensor fasciae latae muscle, to the lateral aspect of the hip, and anastomoses with the terminal branches of the superior ...

This study sought to establish a chronic total occlusion (CTO) model with cell-mediated calcium deposits in rabbit femoral arteries. CTO is the most severe case in atherosclerosis and contains calcium deposits. Previous animal models of CTO do not mimic the gradual occlusion of arteries or have calcium in physiological form. In the present study we tested the strategy of placing tissue-engineering scaffolds preloaded with cells in arteries to develop a novel CTO model. Primary human osteoblasts (HOBs) were first cultured in vitro on polycaprolactone (PCL) scaffolds with 5 ng TGFβ1 loading for 28 days for precalcification. The HOB-PCL construct was then implanted into a rabbit femoral artery for an additional 3, 10 or 28 days. At the time of sacrifice, angiograms and gross histology of arteries were captured to examine the occlusion of arteries. Fluorescent staining of calcium and EDS detection of calcium were used to evaluate the presence and distribution of calcium inside arteries. Rabbit femoral
Results: During the study, it was found that profunda femoris artery was originating abnormally from the femoral artery. Out of 102 limbs that were studied, 47 limbs (46.07%) originated from posterolateral aspect, 20 limbs (19.60%) on lateral aspect, 11 limbs (10.78%) on medial aspect, 24 limbs (23.52%) on posterior aspect of femoral artery. High origin of profunda femoris artery (0- 10 mm) from femoral artery (distance from the midpoint of inguinal ligament) was seen in 2 limbs. ...

Several theories point to the influence of the geometry of femoral arterial bifurcation in the formation and evolution of atherosclerosis plaques at the level of common, superficial and deep femoral arteries. The objective of this study is to correlate the degrees of calcifications of the femoral tripod with different morphological parameters, namely conicity, tortuosity, proximal and distal diameters of the arteries and angles between the common femoral artery (CFA) and the superficial femoral artery (SFA) and the profound femoral artery (PFA) and the superficial femoral artery. The results showed that only the tortuosity of the common femoral artery influences the formation of atherosclerosis plaque. These results allow us to predict the degree of calcification of the femoral tripod based on the tortuosity of the common femoral artery.
Poor aortoiliac or common femoral inflow (i.e. angiographically defined , 50% stenosis of the iliac or common femoral artery) that would be deemed inadequate to support a femoropopliteal bypass graft must be successfully treated prior to treatment of the target lesion. This can be done just prior to treatment of the target lesion. Successful treatment is defined as ,30% stenosis after either PTA or stenting of the inflow lesion. After treatment of the inflow lesion, if the peak to peak pressure gradient across the inflow lesion is ,/= 20mmHg and the peak to peak pressure gradient across the SFA target lesion is ,/= 20mmHg, then the patient will be included in the study ...
Minimal invasive treatment (called endovascular) of the arteries of the lower limb remains problematic, because recurrent disease (restenosis) frequently leads to recurrent symptoms. As yet, balloon angioplasty remains the recommended strategy to revascularize the superficial femoral artery (artery of the thigh). We investigated whether the use of a vascular endoprosthesis (stent) improves patients´ outcome.. Study hypothesis: Primary stenting with self expanding nitinol stents may improve patency after endovascular treatment of superficial femoral artery obstructions compared to balloon angioplasty with optional stenting. ...
Variant origin of lateral circumflex femoral artery (FA) is important during harvesting of anterolateral thigh flaps, aortopopliteal by-pass, coronary artery grafting, and vascularised iliac transplant. The frequencies of variant origins display ethnic variations, but reports from black Africans are scarce. This study, therefore, aimed to describe the variant origins of lateral circumflex FA in a black Kenyan population. Eighty-four (42 right and 42 left) lateral femoral circumflex arteries from 42 cadavers (31 male and 11 female) were exposed by dissection of the femoral triangles at the Department of Human Anatomy, University of Nairobi. The arteries were then traced proximally to their parent trunks. Sites of origin were recorded and representative images of the variations taken using a high-resolution digital camera. Data were analysed using Statistical Program for Social Scientists version 16.0 for Windows and presented in tables and macrographs. The lateral circumflex artery was a branch ...
January 4, 2016-Findings from a study of endovascular treatment of the common femoral artery (CFA) in the Society for Vascular Surgerys Vascular Quality Initiative were published by Jeffrey J. Siracuse, MD, et al online ahead of print in the Journal of Vascular Surgery (JVS). The study was first presented at the 2016 Vascular Annual Meeting of the Society for Vascular Surgery, which was held in June in National Harbor, Maryland.. The investigators noted that endovascular interventions of the CFA and deep femoral artery (DFA) are becoming more common, but there are very little published data for guidance. This study sought to analyze practice patterns and outcomes from these interventions.. As summarized in JVS, the investigators queried the Vascular Quality Initiative for all endovascular interventions of the CFA and DFA from 2010 to 2015. The study excluded cases that were emergent or for acute limb ischemia. Investigators analyzed patients who received isolated CFA intervention with or ...

These variations may not endanger the life of the patients and they are usually subclinical and are found only during surgeries, autopsies and dissections. These variations may be the sources of bleeding at times. The variations which involve the femoral, profunda femoris and the circumflex femoral arteries are important in vascular reconstructive surgeries, in surgical interventions for embolism, catheterization procedures and in raising skin grafts with pedicles. The variations of the lateral circumflex femoral artery are very much useful in making the anterolateral thigh flaps. Hence, here we are ...
The Stanza scaffold is the first self-expanding bioresorbable technology being developed for treatment of atherosclerotic disease in the superficial femoral artery, Holden said. He added that the scaffold design is a composite structure of strong PLGA fibers in combination with an elastomer. This design enables the scaffolds key attributes of flexibility and radial stiffness, similar to self-expanding metallic stents. Preclinical animal studies demonstrate biocompatible resorption of the scaffold over six to 12 months. The scaffold, which uses a conventional retractable sheath delivery system, is being tested in the STANCE trial in target lesions up to 100mm in length and diameters between 4.6-6mm.. The STANCE trial is a prospective, single-arm, multicentre trial of the Stanza scaffold in patients with symptomatic atherosclerotic disease of the superficial femoral artery. The primary endpoint of the trial is major adverse events at six months, with evaluation of vessel patency and other ...

Vasculo-Behçet disease iVBD jis a special type of Behçet disease iBD jinvolving some vascular disorders like aneurysmal formation, arterial occlusion, and venous thrombosis in various vessels. VBD has a poor prognosis due to aneurysmal rupture or recurrence of vascular disorders despite optimal treatment. However, definite diagnosis in BD is made on the basis of clinical features, and early diagnosis is difficult. We report 2 patients whose first clinical symptoms were femoral-pseudoaneurysms. They received a diagnosis of VBD after surgery. The first patient was a 69-year-old man, who underwent autologous-vein patch closure of a perforated region in the left femoral artery. One year later, he had a pseudoaneurysm of the right profunda femoris artery, which was ligated. The second patient was a 51-year-old man, who underwent the interposition of the saphenous vein for defective artery due to left superficial femoral-pseudoaneurysm ...
The treatment of femoropopliteal lesions has known an important evolution in the last years. An important limitation of current endovascular therapy remains the occurrence of restenosis. In order to minimize restenosis rates, drug eluting technologies are evolving. The use of drug-eluting stents (DES) in coronary arteries shows beneficial results, leading to investigation of DES in femoropopliteal arteries. In this article, we give an overview of current available data on treatment with drug eluting technologies in the superficial femoral artery (SFA). This paper su mmarizes also the current available data of the use of drug-coated balloons (DCB) in the femoropopliteal tract. Currently, no data are available on the use of DCB in long lesions. A drug eluting bioresorbable scaffold seems to be very promising in coronary arteries. The transfer to the peripheral area is nowadays ongoing. Which technique and device for which lesion and patient requires further investigation to build up a real ...

Arterial calcifications are more prevalent and more severe in patients with diabetes than in non-diabetics as assessed by a retrospective analysis of 326 plain radiographs of the lower extremities. A more modern retrospective study analyzed 136 randomly selected angiograms and compared peripheral artery disease distribution in diabetics and non-diabetics. Profunda femoris artery and below knee involvement were more prevalent in diabetics. Although ABI >1.3 is common in diabetics, no correlation with ABI was reported in this study. A retrospective study that examined 174 diabetics and 53 control subjects found discrepancy between ABI and toe brachial pressure among diabetics with ABI >1.3, concluding that distal calcifications made the ABI inaccurate. Another retrospective analysis attempted to correlate high ABI with plaque morphology and distribution as assessed by duplex in 184 diabetic patients. In 54 patients with elevated ABI, plaque was found to exist in small collections, distributed ...
Natural adaptation to femoral artery occlusion in animals by collateral artery growth restores only approximately 35% of adenosine-recruitable maximal conductance (C(max)) probably because initially elevated fluid shear stress (FSS) quickly normalize
November 8, 2010 - Patient enrollment has begun in a trial looking at a new system for patients undergoing diagnostic angiography procedures through the femoral artery. The RECITAL study will observe the safety and effectiveness of the Arstasis One access system. It is expected to enroll up to 500 patients in at least seven U.S. hospitals.. Since 1959, physicians have been using the modified Seldinger technique to insert flexible catheters into a patients femoral artery. At the end of every such case, each patient is left with a substantial hole in his/her femoral artery, which typically takes significant effort and cath lab resources to get to stop bleeding. Using the Arstasis One access system, physicians may create a shallow-angle needle pathway through the wall of the femoral artery. At the end of the procedure, all that is needed is approximately three to four minutes of mild, nonocclusive finger-pressure. That - combined with the patients femoral artery blood flow - helps collapse the ...
The wave speed (c) and the arrival time of reflected wave (Trw) in the common left carotid artery and common left femoral artery have been evaluated in 70 healthy subjects, aged 35-55 years with a non-invasive method. Wave speed and the arrival time of reflected waves were determined with lnDU-loop and non-invasive wave intensity analysis (ndI) techniques, respectively. Diameter (D) was measured with ultrasound echo wall tracking and velocity (U) was obtained by ultrasonography. A statistical analysis has been carried out in order to establish a potential relation of c and Trw with gender and age in the study population. Subjects have been divided in two classes of age, one from 35 to 45 years and the other from 45 to 55 years. Results show that c and Trw in the femoral artery are higher than those in carotid, in both men and women (P | 0.001). Also, the distance of the reflection (L) site from the point of measurement is higher in the femoral than in the carotid artery. We did not find statistically
Approach and Results-In vivo studies on femoral artery injury models revealed that vascular injury triggered an immediate upregulation of XBP1 expression and splicing in vascular SMCs and that XBP1 deficiency in SMCs significantly abrogated neointimal formation in the injured vessels. In vitro studies indicated that platelet-derived growth factor-BB triggered XBP1 splicing in SMCs via the interaction between platelet-derived growth factor receptor β and the inositol-requiring enzyme 1α. The spliced XBP1 (XBP1s) increased SMC migration via PI3K/Akt activation and proliferation via downregulating calponin h1 (CNN1). XBP1s directed the transcription of mir-1274B that targeted CNN1 mRNA degradation. Proteomic analysis of culture media revealed that XBP1s decreased transforming growth factor (TGF)-β family proteins secretion via transcriptional suppression. TGF-β3 but not TGF-β1 or TGF-β2 attenuated XBP1s-induced CNN1 decrease and SMC proliferation. ...

AIM: The aim of this study was to analyze the intermediate results of selective stenting of superficial femoral artery (SFA) lesions after a suboptimal balloon angioplasty result. METHODS: We analyzed 70 consecutive patients with claudication or crit
The articularis genus (subcrureus) is a small skeletal muscle located anteriorly on the thigh just above the knee. It arises from the anterior surface of the lower part of the body of the femur, deep to the vastus intermedius, close to the knee and from the deep fibers of the vastus intermedius. Its insertion is on the synovial membrane of the knee-joint. It is supplied by the lateral femoral circumflex artery. It is innervated by branches of the femoral nerve (L2-L4). Flat, wispy and highly variable, sometimes consisting of several separate muscular bundles, this muscle is without a distinct investing fascia and ranges 1.5-3 cm in width. It is usually distinct from the vastus intermedius, but occasionally blended with it.[needs update] Articularis genus pulls the suprapatellar bursa superiorly during extension of the knee, and prevents impingement of the synovial membrane between the patella and the femur.

The treatment of infrainguinal arterial disease has changed significantly in the last 20 years, with the introduction of many new devices and therapies. There are now numerous options to restore flow through or around the superficial femoral artery (SFA) to provide adequate perfusion to the leg. In this article we will discuss the current approach to SFA reconstruction, including identification of the extent of disease with imaging, and an algorithm to treat disease using both open and endovascular approaches.. ...
How is Left Atrial to Femoral Artery abbreviated? LA-FA stands for Left Atrial to Femoral Artery. LA-FA is defined as Left Atrial to Femoral Artery very rarely.
Increasingly, health plans, employers, and accreditation agencies are looking for providers of valued care. However, the definition of this term is still elusive among payers, employers, consumers, and regulators in markets around the world. Even more importantly, the precise relationship between cost and quality is not yet established in many fields of medicine. As practitioners who perform endovascular procedures that often utilize advanced (and costly) technology, we are at the forefront of this discussion.. In the superficial femoral artery (SFA), we now have multiple technologies that can be used and randomized trials demonstrating the benefits of some of these approaches. However, there remains a disconnect in that many of the approval trials excluded the most common lesions we treat. We also lack head-to-head comparisons of advanced technology beyond that of basic angioplasty. Some institutions have gone so far as to remove physicians from the procurement process, thus limiting choice ...

The use of drug-coated balloons (DCBs) with anti-proliferative agents in treating femoropopliteal lesions was approved in Japan in 2017. A better limb salvage rate or amputation-free rate of DCBs relative to plain old balloon angioplasty (POBA) has been reported; however, there is little evidence of the direct effect on intimal hyperplasia (IH). A 70-year-old man with chronic limb-threatening ischemia and foot gangrene had undergone bypass surgery from the left common femoral artery to the dorsalis pedis artery 2 years earlier. We evaluated the bypass graft using ultrasonography and found stenosis around the proximal anastomotic site, presumably due to IH. POBA was performed every 3 months due to the repeated re-stenosis of the lesion. Since using the DCB, no restenosis has been detected to date (10 months). DCB might be an effective tool for treating re-stenosis due to IH or vein grafts that do not respond to POBA.

We have shown that inhibition of NO production by l-arginine analogues significantly attenuated the development of PSD. To the best of our knowledge, this is the first report of pharmacological antagonism of PSD. Furthermore, the enhanced vascular reactivity of vessel rings to acetylcholine in the poststenotic region is consistent with an important role for endothelium-produced NO as a mediator of PSD. In the present study, large-scale turbulence throughout the flow field is not expected, because the upstream, time-averaged Reynolds numbers were ,100, based on the mean velocity. Turbulence would be expected to occur in this geometry at a Reynolds number of 300 to 400.42 In light of several reports12 13 14 16 17 of steady unidirectional laminar shear stress inducing NO production and elevating eNOS gene expression levels in cultured endothelial cells, elevated wall shear stress or rapid changes in direction and magnitude of wall shear stress are the likely initiators of PSD. This linkage was ...

Primary femoral aneurysms are uncommon and are frequently associated with other aneurysms, particularly those of the aorta and popliteal arteries. True isolated atherosclerotic aneurysm of the superficial femoral artery is a rare pathology [2].. Rigdon et al discussed 17 arteriosclerotic superficial femoral artery aneurysms in 14 patients, which revealed complication at presentation in 65% - rupture in 35%, thrombosis in 18%, and distal emboli in 12%. However, limb salvage was 94% and there were no perioperative deaths [3]. Males (75%) were more common than females, and the average age was 77 years (range 61 to 93) [3].. True femoral artery aneurysms are attributed to weakening of the arterial wall due to atherosclerosis. True femoral artery aneurysms are relatively rare and are found in elderly men who have strong smoking history. Aortic aneurysms are approximately 10 times more common. According to Levi et al distal embolization occurs in 0-26% of cases, acute thrombosis occurs in around 15% ...
A 79-year-old man, with a background of peripheral vascular disease, presented to the emergency department with a sudden increase in the size of his swelling in the right thigh, indicating rupture of his right superficial femoral artery aneurysm. His past medical history included having had a left femoropopliteal bypass (1986), abdominal aortic aneurysm repair (1991), repair of false aneurysm on the right (1992) and repair of left common femoral artery aneurysm (1995). On surgical exploration, four contiguous aneurysms in the right superficial femoral artery were identified, which measured around 25 cm in total length. After achieving control of the aneurysm, it was noted that the popliteal artery was unsuitable for anastomosis. However, the leg was still adequately perfused via collaterals in spite of the ligation, so nothing further was done. The patient was put on a heparin infusion postoperation, and had an uneventful recovery with a viable limb on discharge. It is a useful reminder that ...

The deep femoral vein (also known as the profunda femoris) flows along with the profunda femoris artery. It has tributaries that correspond to the perforating branches of this artery. Through these tributaries it communicates with the inferior gluteal vein higher up and the popliteal vein lower down. The medial and lateral femoral circumflex veins are also received.

We treated a patient with late-stage unilateral bypass thrombosis after bilateral axillary-femoral bypass with lateral axillary-profunda femoris artery (LAx-PF) bypass. A 64-year-old male patient was admitted to our hospital for acute left lower limb ischemia. Six years ago, he underwent bilateral axillary-femoral bypass due to Leriche syndrome. On emergency admission, thrombosis of the left bypass vessel was identified. Blood flow could not be restored due to failure to restore patency of the proximal and distal anastomosis of the left bypass vessel during surgery. We performed LAx-PF bypass surgery to successfully rescue the limb, which was on the verge of necrosis. If thrombectomy cannot restore blood flow in the previous axillary-femoral bypass, LAx-PF bypass is an easy procedure to rescue the ischemic limb.

Freedom from a composite of target vessel restenosis, major index limb amputation, and device- or procedure-related death at 30 days was defined as the primary endpoint. The primary effectiveness endpoint was freedom from target lesion restenosis at 12 months. Secondary endpoints were acute device and procedural success and clinically assessed primary patency, the authors write.. Results. The registry results showed a 99.4% freedom at 30 days from the composite safety endpoint. There was 89.3% freedom from target lesion restenosis in the overall population at 24 months. In long lesions up to 50cm, the freedom from target lesion restenosis was 88.2%; in patients with in-stent restenosis this figure was 84.6%. The clinically assessed primary patency was 75.6% and more than 76% of patients showed improvement of at least one Rutherford category.. Editorial comment. In an accompanying editorial comment in the journal, Ivan P Casserly, Dublin, Ireland, writes: Most endovascular specialists are ...
The femoral artery is commonly used for cannulation in peripheral VA-ECMO due to its ease of access. As the return cannula is placed in a retrograde direction in the femoral artery, perfusion of the ipsilateral lower limb may be compromised as the direction of blood flow from the return cannula is opposite to that from the native heart. The risk of distal limb ischaemia is even higher if large-size cannulas are used. Successful distal limb perfusion in VA-ECMO has been reported using various approaches, including antegrade cannulation of the superficial femoral artery, and retrograde cannulation of the dorsalis pedis or posterior tibial artery.15 16 17 Antegrade percutaneous cannulation of the superficial femoral artery is the most commonly used technique in our locality. The reperfusion cannula should be placed using the Seldinger technique under fluoroscopic or ultrasound guidance. If ultrasound is used, in-plane visualisation is helpful to differentiate the superficial femoral artery from the ...

Our prospective study demonstrates that LE-PAD patients with a hypoechoic plaque in the femoral arteries are exposed to a significantly higher risk of developing myocardial infarction or stroke compared with those with a hyperechoic femoral plaque. Similar findings were obtained with both computer-assisted and visual analyses of plaque echogenicity. Notably, these results remained unaltered after accounting for factors known to have important impacts on LE-PAD patients outcome, including age, sex, previous cardiovascular events, and ABI.. Acute ischemic events are more closely related to the histopathological characteristics of atherosclerotic plaques than to the number of plaques or the degree of vascular stenosis (2,5-8,28,29). In this regard, the PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) trial (8) has recently shown that lesions responsible for recurrent cardiac ischemic events are frequently angiographically mild, most are thin-cap ...
A 61-year-old man with acute myocardial infarction developed a painful hematoma in his groin after percutaneous coronary intervention. Ultrasonography, including color Doppler, detected a pulsatile, hypoechogenic, single compartment lesion (2.3 × 3.0 × 2.9 cm) consistent with a partially thrombosed pseudoaneurysm originating from the distal part of the common femoral artery (Figure, A). Sampling from the neck of the pseudoaneurysm connecting the pseudoaneurysm to the common femoral artery, spectral Doppler waveform analysis unexpectedly displayed flow directed toward the pseudoaneurysm cavity both in systole and diastole (Figure, B), in contrast to the characteristic to and fro-like flow pattern detected in uncomplicated pseudoaneurysms (Figure, C). The turbulent monophasic flow of the pseudoaneurysm neck, with its characteristic high end-diastolic velocities (Figure, B), suggested flow to an area of low peripheral resistance, in contrast to the normal high-resistance biphasic arterial flow ...

Introduction: Disease of the femoropopliteal artery (FPA) is associated with significant morbidity and quality of life impairment. End-stage lesions may be too advanced to determine how demographics and clinical risk factors impact arterial wall damage and lesion development; therefore we investigated the influence of these patient characteristics on various stages of human FPA histopathology.. Methods: FPAs were obtained from 14-80 year-old human tissue donors (n=120). Proximal segments of the arteries were mechanically tested and labeled with Verhoeff-Van Gieson stains. FPA intimal-medial damage severity was assessed and correlated with histology, mechanical properties, subject demographics, risk factors, and physiological stresses and stretches using Pearson correlation r with two-tailed significance levels.. Results: Age correlated strongest (r=0.664, p,0.01) with the degree of FPA intimal-medial damage, explaining 50% of the variation alone. Primarily due to medial calcification, more ...

Click the title to purchase the article.. Abstract:. Femoro-femoral cardiopulmonary bypass (CPB) followed by deep hypothermic circulatory arrest is one of the modalities used for ascending aortic pseudoaneurysmrepair to achieve cardiac unloading and to avoid severe hemorrhage due to the risk of rupture during the sternal entry. However, due to the limited size of the cannulas, it can be challenging to achieve total cardiopulmonary support. Therefore, despite the achievement of total cardiopulmonary support, the heart may still be able to eject antegrade blood flow that meets the retrograde blood flow from the arterial side of the CPB. The point where the blood flow meets in the aorta is called the watershed area. If the antegrade blood flow is large due to a left ventricular ejection, the watershed area will be located in the descending aorta. Therefore, if ventilation is stopped, deoxygenated blood will be ejected to the cerebral circulation. Cerebral near-infrared spectroscopy (NIRS) may be ...

Certain factors like ostial disease, chronic total occlusion, and long, multiple stents are the main causes of multiple stent fractures, as were present in this case. Such stent fractures are usually associated with significant in-stent restenosis; however, this patient had a patent lumen despite multiple fractures.

THE STUDY The study involved around 31 healthy non-smoking adults in the age group of 24 years. An MRI was undertaken before and after them using nicotine free e-cigarettes. The participants had to take 16 puffs in total with each lasting for 3 seconds.. The e-cigarette content was free from nicotine but included glycerol and propylene glycol with a tobacco flavor. The researchers measured reactive hyperemia or a short rise in the arterial blood flow post occlusion, of their subjects after they constricted and released their blood vessels.. The MRI scans did show that there was a reduction in the femoral arterys blood flow. Femoral is the main artery responsible for delivering blood to the thigh and leg area of the body. Another note that the team made was about reduction in reactive hyperemia as well.. Based on the study, the researchers concluded that smoking nicotine free e-cigarette aerosol does affect the endothelial function in healthy smokers transiently. Endothelial is the thin cell ...

Back to the AimRADIAL course, co-organizer and radial pioneer, Olivier F. Bertrand, MD, PhD, told Angioplasty.Org that Besides usual themes, special emphasis will be placed this year on 1) peripheral intervention and radial approach, 2) use of dedicated universal catheters versus standard catheters, 3) cost benefits for radial approach in the USA and around the world, including new practice such as same-day discharge, 4) how to use new anticoagulants and new antiplatelets in the lab, 5) radial artery injury and occlusion: prevention and treatment.. This last point is interesting. Because the radial approach is positioned as a safer alternative to femoral, most radialists are very sensitive to the subject of complications. And, like any medical procedure, there are complications to the transradial approach, but they are small in percentage. However, they do exist and there are several lectures on the program about possible complications, how to avoid them, and what to do about them when they ...

To introduce a new, efficient method for vessel-wall imaging of carotid and peripheral arteries by means of a flow-sensitive 3D water-selective SSFP-echo pulse sequence. Periodic applications of RF pulses will generate two transverse steady states, immediately after and before an RF pulse; the latter being referred to as the SSFP-echo. The SSFP-echo signal for water protons in blood is spoiled as a result of moving spins losing phase coherence in the presence of a gradient pulse along the flow direction. Bloch equation simulations were performed over a wide range of velocities to evaluate the flow sensitivity of the SSFP-echo signal. Vessel walls of carotid and femoral and popliteal arteries were imaged at 3 T. In two patients with peripheral artery disease the femoral arteries were imaged bilaterally to demonstrate methods potential to visualize atherosclerotic plaques. The method was also evaluated as a means to measure femoral artery flow-mediated dilation (FMD) in response to cuff-induced ischemia

Prevention includes the use of breast milk and probiotics.[2] A 2012 policy by the American Academy of Pediatrics recommended feeding preterm infants human milk, finding "significant short- and long-term beneficial effects," including reducing the rate of NEC by a factor of two or more.[10] Small amounts of oral feeds of human milk starting as soon as possible, while the infant is being primarily fed intravenously, primes the immature gut to mature and become ready to receive greater intake by mouth.[11] Human milk from a milk bank or donor can be used if mother's milk is unavailable. The gut mucosal cells do not get enough nourishment from arterial blood supply to stay healthy, especially in very premature infants, where the blood supply is limited due to immature development of the capillaries, so nutrients from the lumen of the gut are needed. A Cochrane review in 2014 found that supplementation of probiotics enterally "prevents severe NEC as well as all-cause mortality in preterm ...
