Superficial femoral artery pseudoaneurysm at implantation site of drug eluting stent discovered due to bacteremia:A case report

BACKGROUND Drug-eluting stents(DES)are used to treat lower extremity arterial disease.During DES treatment,aneurysmal degeneration occasionally occurs,especially with fluoropolymer-based DES.However,the incidence of pseudoaneurysms after DES placement is rarely reported in the lower extremity region,although there have been several reports on pseudoaneurysm formation after DES placement in the coronary artery region.CASE SUMMARY We report the case of a 64-year-old man who presented with fever and pain in his left hand after dialysis.Bacteremia was diagnosed by blood culture,and after admission,he developed pain on the medial side of the right thigh.A pseudoaneurysm was observed in the right superficial femoral artery(SFA)at the proximal end of a previously placed DES.The bacteremia was thought to have been caused by a pseudoaneurysm of the left superficial brachial artery,and the pseudoaneurysm of the left superficial brachial artery was removed after antibiotic treatment.The pseudoaneurysm of the right SFA rapidly expanded after admission,but the expansion rate was reduced after infection control.Seven months after the first admission,the pseudoaneurysm of the left SFA was re-moved and in situ revascularization performed using a rifampicin-soaked Dacron graft.CONCLUSION Although pseudoaneurysm after DES placement in the lower extremity region is rare,it must be considered in patients with bacteremia.

Sequential bowel necrosis and large gastric ulcer in a patient with a ruptured femoral artery:A case report

BACKGROUND Severe bleeding as a result of a major vascular injury is a potentially fatal event commonly observed in the emergency department.Bowel necrosis and gastric ulcers secondary to ischemia are rare due to their rich blood supply.In this case,we present the case of a patient who was treated successfully following rupture of his femoral artery resulting in bowel necrosis and an unusually large gastric ulcer.CASE SUMMARY A 28-year-old male patient sustained a knife stab wound to the right thigh,causing rupture of his femoral artery and leading to massive bleeding.He underwent cardiopulmonary resuscitation and received a large blood transfusion.Abdominal surgeries confirmed bowel necrosis,and jejunostomy was performed.The necrotic intestine was removed,the remaining intestine was anastomosed,and the right thigh was amputated.After three surgeries,the patient's overall condition gradually improved,and the patient was discharged from the hospital.However,one day after discharge,the patient was admitted again due to dizziness and melena,and a gastroduodenoscopy revealed a giant banded ulcer.After 2 weeks of treatment,the ulcer had decreased in size without bleeding.Six months after the last surgery,enterostomy and reintroduction surgery were completed.The patient was fitted with a right lower limb prosthesis one year after surgery.After 3 years of follow-up,the patient did not complain of discomfort.CONCLUSION Trauma department physicians need to be aware of the possible serious complications involving the abdomen of trauma patients with massive bleeding.

Pharmacokinetics of Native r-SAK in Rabbit's Femoral Artery Thrombosis Model

Objective: To study the pharmacokinetics of native r SAK in rabbit's femoral artery thrombosis model, the “lytic circle' method was used to determine plasma levels of r SAK. Methods: Thirty New Zealand rabbits were randomly assigned to the control (saline 10 ml, 30 min), r SAK low dose (0.25 mg/kg, 30 min), medial dose (0.50 mg/kg, 30 min), high dose (1.00 mg/kg, 30 min), single bolus (0.50 mg/kg, 2 min) and conjunctive therapy (initiated with heparin 200 U/kg, followed by infusion of r SAK 0.50 mg/kg for 30 min, and subsequently infused heparin 50 U/(kg·h) to endpoint) groups. The right femoral artery thrombosis model in rabbit was made by balloon injury, then the thrombolytic agents were infused through parallel ear vein and the blood samples were collected pre thrombolysis and at different time post thrombolysis to determine the plasma levels of r SAK by “lytic circle' method, the plasma levels of r SAK were processed by pharmacokinetic computing procedure to fit the model. Results: The plasma levels of r SAK and the diameters of lytic circles showed a pretty good linear correlation under the scope of 2.0×10 4 2.0×10 6 U/L, and the averaged recycle rate was (96.05±11.35)%(RSD =±11.82%).All peak concentration time in each infusion group was 30 min, and the peak concentrations positively correlated with the doses administrated in infusion groups(r=0.999 98, P <0.000 1). In single bolus group, Peak concentration time was 2 min, and the peak concentration reached (5.16±1.02) mg/L, which was significant higher than that in the same dose r SAK infusion group ( P <0.01). In conjunctive therapy group, the peak concentration showed no significant difference from that in the same dose r SAK infusion group ( P >0.05). The plasma levels of r SAK fit in two compartment model as processed by pharmacokinetic computing procedure in each group. Conclusion: The “lytic circle' method is a simple, practical and reliable method to determine the plasma level of r SAK, and the pharmacokinetics of native r SAK infusion fits in two compartment model in rabbit's femoral artery thrombosis model.

Unusual disposition of lateral circumflex femoral artery: Anatomical description and clinical implications

The anatomical knowledge of arterial variations of lower limb is of utmost significance for the present day surgeons and interventional radiologists for minimizing complications during vascular reconstructive procedures, catheterization procedures and surgical intervention for embolism. Lateral Circumflex Femoral Artery(LCFA) isan important branch of Profunda Femoris artery and precise knowledge of its variations can be of great relevance during surgical and radiological procedures in femoral region. The present study reports a unique case of anomalous route taken by LCFA posterior to femoral nerve associated with a prominent muscular branch from Femoral artery mimicking the course of LCFA. Documentation of such variations is highly significant. It may serve as guideline for surgeons in reducing the incidence of postoperative complications where LCFA is used as a long vascular pedicle in anterolateral perforator thigh flap and in breast reconstruction after mastectomy. Ignorance of such variations can lead to fatal intraoperative haemorrhage and incapacitating sensory and motor deficit due to injury to femoral nerve branches which are closely related to these vessels.

Profunda femoris artery pseudoaneurysm following revision for femoral shaft fracture nonunion

Femoral artery pseudoaneurysms(FAPs) have been described following internal fixation of intertrocantheric, subtrocantheric and intracapsular femoral neck fractures as well as core decompression of the femoral head. The diagnosis of FAP is usually delayed because of non-specific clinical features like pain, haematoma,swelling, occasional fever and unexplained anaemia.Because of the insidious onset and of the possible delayed presentation of pseudoaneurysms, orthopaedic and trauma surgeons should be aware of this complication. We report a case of Profunda Femoris arterial branch pseudoaneurysm, diagnosed in a 40-year-old male 4 wk after revision with Kuntscher intramedullary nail of a femoral shaft nonunion. The diagnosis was achieved by computed tomography angiography and the lesion was effectively managed by endovascular repair. The specific literature and suggestions for treatment are discussed in the paper.

Dissection and ligation of the lateral circumflex femoral artery is not necessary when using the direct anterior approach for total hip arthroplasty

BACKGROUND Branches of the lateral circumflex femoral artery(LCFA) stretch across the surgical field during a direct anterior total hip arthroplasty. It is an anatomical marker in direct anterior approach. As an important vessel around the hip joint,this vessel was ligated in most situations. Although ligation of the vascular pedicle of the LCFA is a common, traditional procedure used to decrease bleeding, the ligation of the pedicle of the vessel is tedious and time-consuming.AIM To explore whether this ligation is truly necessary in a direct anterior approach to total hip arthroplasty.METHODS This single-center, single-surgeon, prospective study was performed to compare patients' bleeding undergoing ligation of the branches of the LCFA pedicle(group A) vs those treated with electrocautery from the branches of the LCFA(group B). In both groups, the pedicles were identified in the intermuscular plane between the tensor fasciae lata and the rectus femoris muscles. In group A, the pedicles were ligated with a silk ligature. In group B, the branches coming off the LCFA were controlled with electrocautery. We compared preoperative vs postoperative changes in blood hemoglobin levels, intraoperative blood loss,operative time, rates of transfusion, re-bleeding, and hematoma between the two groups.RESULTS The reduction of hemoglobin in group A was 20.9 ± 7.0, and in group B it was 21.2 ± 4.9. There was no statistically significant difference between the two groups(P > 0.05). The actual calculated blood loss in group A was 784 ± 125 mL,and in group B it was 722 ± 153 mL. There was a trend in group A having more blood loss(P = 0.078). The estimated blood loss in group A was 344 ± 88 mL, and in group B it was 346 ± 73 mL. There was no statistically significant difference between the two groups(P = 0.883). In addition, there were no significant differences in the rates of postoperative transfusion(10% vs 6.7%, P > 0.05),postoperative hematomas(6.7% vs 13.3%, P > 0.05), or re-bleeding(13.3% vs 20%,P > 0.05) between the two groups.CONCLUSION Ligation of the pedicle of the LCFA has no advantage in preventing or decreasing bleeding during or after a total hip arthroplasty using the direct anterior approach. Ligation of the pedicle of the vessel is a cumbersome, unnecessary procedure and can be replaced by electrocautery control of the branches off this artery that course through the surgical field.

Missed diagnosis of femoral deep artery rupture after femoral shaft fracture: A case report

BACKGROUND Vascular injury is a rare complication of femoral shaft fractures,and rupture of the deep femoral artery is more difficult to diagnose because of its anatomical location and symptoms.Despite its low incidence,deep femoral artery rupture can lead to life-threatening outcomes,such as compartment syndrome,making early identification and diagnosis critical.CASE SUMMARY A 45-year-old male patient was admitted to our hospital due to right lower limb trauma in a car accident,with complaints of severe pain and swelling on his right thigh.X-ray demonstrated a right femoral shaft fracture.During preparation for emergency surgery,his blood pressure and blood oxygen saturation dropped,and sensorimotor function was lost.Computed tomography angiography was performed immediately to confirm the diagnosis of rupture of the deep femoral artery and compartment syndrome,so fasciotomy and vacuum-assisted closure were performed.Rhabdomyolysis took place after the operation and the patient was treated with appropriate electrolyte correction and diuretic therapy.Twenty days after the fasciotomy,treatment with the Hoffman Type II External Fixation System was planned,but it was unable to be immobilized internally based on a new esophageal cancer diagnosis.We kept the external fixation for 1 year,and 3 years of follow-up showed improvement of the patient’s overall conditions and muscle strength.CONCLUSION For patients with thigh swelling,pain,anemia,and unstable vital signs,anterior femoral artery injury should be highly suspected.Once diagnosed,surgical treatment should be performed immediately and complications of artery rupture must be suspected and addressed in time.

The Configuration of the Femoral Arterial Bifurcation’s Influence on Its Atherogenesis

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.

Blood Flow Simulation in the Femoral Artery

This paper presents the development of the blood flow simulation in two dimensions over the real geometry of the femoral artery. The Navier-Stokes equations are solved using the finite element method, to obtain the distributions of the blood pressure and flow velocity in multiple instants of time and different places of the femoral artery and thus determine the current condition of the blood vessels. The velocity field shows a laminar behavior,where, the velocity is higher in the center of the artery and decreases as the blood flow approaches artery walls. In spite of all artery and blood flow properties not being considered, the values of pressure and velocity obtained are within the normal ranges. Finally the model is used to verify if there exist irregularities in the blood flow in both healthy subjects and sick patients.

The Contemporary Role of Femoral Artery Access

The scope of interventional cardiology has rapidly expanded over the last several decades.In a field where procedural treatment options for a variety of complex cardiovascular conditions have grown exponentially,the importance of procedural safety continues to come to the forefront.This is most evident in the movement toward radial access as the initial approach for operators in the cardiac catheterization laboratory.As the evidence grows for the superiority of radial access over femoral access with regard to reducing bleeding events and improving clinical outcomes,we discuss the modern approach to obtaining access,and highlight best practices.

Treatment of Atherosclerotic Disease of the Femoral Artery: Randomized Controlled Trials and Meta-Analyses. Should You Be Sceptical?

A narrative review of the data provided by Randomised Controlled clinical trials and meta-analyses was undertaken to assess how much reliance a clinician could place on these in selecting a treatment for patients with disease of the Femoral artery. An attempt was made to detect and review every clinical trial and meta-analysis published on treatments relating to disease of the femoral artery but not relating to drug treatment. Disease of the femoral artery in >65 years age group occurs in approximately 20% of the population but symptomatology was present in 40%. In almost all trials the predominant (>90%) indication for treatment was intermittent claudication. In this setting, clinical benefit was limited and did not extend beyond 12 months. Mortality, from co-morbidities was high. The Basil Trial was the only one to examine intervention for critical limb ischemia. The results for Bypass surgery and Percutaneous transarterial balloon angioplasty (PTA) were equivalent. There is little evidence to support the use of PTA or stenting other than in the treatment of patients with critical limb ischemia.

Long Term Clinical and Angiographic Outcome Following Percutaneous Transluminal Angioplasty and Stent Placement for Iliac and Femoral Artery Stenosis

Objective This study reportsthe initial and late results of percutaneous transluminal angioplasty (PTA) and intravascular stenting for atherosclerotic stenosis of the iliac and femoral arteries. Methods and Results From December 1994 to March 1997, we performed iliac and femoral artery angioplasty and primary intravascular stent placement in 37 vessel of 33 patients (19 men and 14 women; mean age, 70. 5 years). A total of 43 self - expanding Wallstents (Boston, Inc. ) were deployed. All patients underwent angioplasty and stent placement successfully. Clinical follow - up was available for all patients at a mean of 26±14months. All patient clinical is-chemic category (claudication or rest pain) was improved. Angiographic follow - up was completed for 17 of 23 patients at a mean follow-up of 10±5 months, The iliac artery restenosis rate was 0(0/8). The femoral artery restenosis rate was 33 % (3/9), All 3 patients underwent repeat balloon angioplasty successfully. Conclusion The iliac and femoral arteries can be performed and reasonable early and late patency rates.

Dissection of the Common Femoral Artery at the Bamako Anatomy Laboratory

Objectives: The purpose of this work was to determine the dimensions of CFA before the birth of the deep thigh artery, describe the mode of termination of the CFA, search for CFA collaterals, and describe the anatomical variations of the CFA. Methodology: This was a prospective study conducted at the Anatomy Laboratory of the Faculty of Medicine and Odonto-Stomatology of Bamako. CFA arteries of 12 fresh corpses of adults include 9 men and 3 women. A total of 24 CFA arteries were dissected and photographed. Results: The mean length of CFA was 50.9 ± 12.55 mm (range: 31 and 93 mm). Its average diameter was 9.12 ± 1.17 mm (range: 7 and 12 mm). In 70.83%, the CFA artery ended without any particularity. There was 29.17% anatomic variation in the CFA termination mode. The CFA divided into 3 branches (trifurcation) in 25%. The 3 branches were in 20.83%, the FS and a common core to LFCA and AQ;in 4.17%, they were the SFA, the DFA and the MFCA. In 4.17%, it divided into 4 branches which are: the SFA, the DFA, the MFCA and a common core to QA and LFCA. The CFA gave as collateral: circumflex superficial iliac artery in 22 cases (91.67%), superficial epigastric artery in 19 cases (79.17%), upper external pudendal artery in 20 cases (83.33%), and lower external pudendal artery in 14 cases (58.33%). We noted in our series 9 anatomical variations at the collateral level of the CFA or 37.5%. The CFA gave birth to the following branches: the MFCA in 4 cases or 16.67%, the LFCA in 1 case or 4.17%, the QA in 1 case or 4.17%, and a common core to the QA and LFCA in 3 cases or 12.5%. Conclusion: The length of CFA is important. The variations of CFA are frequent and important to know in clinical and surgical practice.

Anatomic Dissection of the Femoral Vein at the Bamako Anatomy Laboratory

Objectives: The purpose of this work was to measure the dimensions of the femoral veins, to describe the affluent and the variations of the femoral veins. Methodology: Twenty-four femoral veins of 12 fresh adult cadavers were dissected and photographed. Results: The diameter of the superficial, deep and common femoral veins was respectively 8.75 mm;7.60 mm and 13.95 mm. The common femoral vein was 80.70 mm long. At the level of the superficial vein, the modal disposition was noted in 79.17%;as anatomical variations, it was split in 2 cases, the presence of a collateral canal in 1 case and in 2, and it received a quadricipital muscle vein. At the level of the deep femoral vein, the modal disposition was noted in 16.67%, and the anatomical variations were noted in 83.33% where it received no affluent in the femoral trine. The modal disposition was noted in 91.67% at the level of the mode of birth of the common femoral vein, in 16.67% at the level of its tributaries. The anatomical variations were noted in 8.33% in the mode of birth of the femoral vein, in 83.33% in which the common femoral vein received, in addition to the large saphenous vein, other tributaries, the most frequent of which were the quadricipital veins and the circumflex femoral veins. Conclusion: The diameter of the femoral veins is important. The main tributaries of the common femoral vein are GVS, VQ and circumflex femoral veins. The femoral variations are numerous and important to know to avoid a possible misdiagnosis in case of their thrombosis.

Removal of a pulmonary artery foreign body during pulse ablation in a patient with atrial fibrillation:A case report

BACKGROUND Foreign bodies in the pulmonary circulation have been documented in the literature and are typically caused by interventional procedures.However,reports of pulmonary artery foreign bodies during femoral vein puncture are rare,and there is no description of this complication from the guidewire surface flows into the pulmonary artery during a pulse ablation in a patient with atrial fibrillation.CASE SUMMARY We described a case in which a linear foreign body suddenly appeared on fluoroscopy image during pulsed ablation of atrial fibrillation.Multiposition angiography showed that the foreign body was currently lodged in the pulmonary artery but was hemodynamically stable.We then chose to use an interventional approach to remove the foreign body from the pulmonary artery.This foreign body was subsequently confirmed to be from the hydrophilic coating of the guidewire surface.This may be related to the difficulties encountered during the puncture of the femoral vein.This is a rare and serious complication of femoral vein puncture.Therefore,we reported this case in order to avoid a similar situation.CONCLUSION Mismatches between interventional devices from different manufacturers used for femoral venipuncture may result in pulmonary artery foreign bodies.
