Infection Risk Following Common Femoral Artery Endarterectomy Versus a Hybrid Procedure.

BACKGROUND: Hybrid revascularization combines open lower extremity surgery and endovascular procedures to simultaneously treat atherosclerotic lesions on multiple levels in patients with peripheral arterial occlusive disease (PAD). Hybrid surgery appears to be a safe strategy for multilevel stenosis revascularization, though the risk of surgical site infection (SSI) has not been clearly investigated. This study evaluates the development of SSI following common femoral artery endarterectomy (CFE) and hybrid revascularization procedures. METHODS: A retrospective study was performed including all patients undergoing CFE, as standalone or as part of a hybrid procedure, due to PAD between January 2013 and December 2016. Preoperative, intraoperative, clinical, and follow-up information was gathered prospectively and reviewed retrospectively. The presence of SSI was recorded based on criteria of the Centre for Disease Control. RESULTS: A total of 229 CFEs were performed. One hundred thirty-two as a standalone procedure, 65 combined with iliofemoral angioplasty, and 32 combined with peripheral angioplasty. Nineteen patients (8.3%) developed an SSI, of which 4 were deep infections. Ten infections (7.6%) occurred in the CFE-only group, 5 (7.7%) in the iliofemoral hybrid group, and 4 (12.5%) in the peripheral hybrid group (P = 0.65). Five patients (2.1%) required surgery to control the infection. The mean duration of stay was 5 days for patients without SSI versus 20 days for patients who developed an SSI (P < 0.0001). CONCLUSIONS: The hybrid procedure combining open femoral endarterectomy with endovascular revascularization is a safe procedure with no significant differences in infection rates between open surgery, central, or peripheral hybrid revascularization.

Dementia in Patients Suffering from Critical Limb Ischemia.

BACKGROUND: Critical limb ischemia (CLI) is a disease that is most prevalent in the elderly population. This group of patients includes patients suffering from comorbidities such as dementia. Mortality rates of both CLI and dementia are higher when compared with the nonaffected population. These demented vascular patients are often deemed unfit for surgery and at risk of respiratory and cardiovascular adverse events. Unfortunately, current literature is lacking in to determining the optimal treatment for demented patients suffering from CLI. The purpose of this study is to determine the prevalence of dementia in patients suffering from CLI, with special interest in the mortality rates of these patients. METHODS: Between January 2012 and October 2015, all patients aged over 70 and suffering from CLI were retrospectively reviewed in the Amphia Hospital, Breda, The Netherlands. Patients with diagnosed dementia before admission by a geriatrician were included in this study. Baseline characteristics were retrieved from patients' medical charts. Primary end point of this study is mortality and the secondary end points include adverse events, reinterventions, and limb salvage. RESULTS: A total of 369 patients suffering from CLI were diagnosed between January 2012 and October 2015. Thirty-one patients (8%) diagnosed with both dementia and CLI were included in this study with a mean age of 82 years old. Conservative therapy was selected as the therapy of choice in 61% of the patients. There was a mortality rate of 32% after 6 months, increasing to 52% after 1 year and 92% after 2 years. Limb salvage rates after 30 days were 84%, dropping to 77% after 6 months. CONCLUSIONS: Eight percent of CLI patients aged above 70 years old are suffering from dementia. Demented patients suffering from CLI are a frail group of elderly patients with a high mortality rate of 52% after 1-year follow-up. Therapy of choice should probably be selected following mutual agreement between vascular surgeons, individual patients, and their families, taking postoperative quality of life, life expectation, and anatomical arterial lesions into account.

Quality of Life in Patients Suffering from Critical Limb Ischemia.

BACKGROUND: Various treatment options exist for patients suffering from critical limb ischemia (CLI). These options consist of endovascular procedures, surgical revascularization, primary amputation, or conservative therapy. The effect of the treatment is traditionally focused on outcomes, such as primary patency and limb salvage, though quality of life (QoL) is considered an important additional primary end point in a more patient-oriented healthcare system. The aim of this systematic review is to explore the best clinical decision making possible, to increase QoL in CLI patients. METHODS: This review is based on a systematic electronic literature search using the PubMed and EMBASE databases. Articles evaluating QoL in patients with CLI were selected for further analysis. Only prospective studies, written in English, describing QoL and health status (HS) after endovascular or surgical revascularization, amputation or conservative therapy were considered for inclusion. Treatment results were divided into short-term (≤3-month follow-up) and long-term results (≥1-year follow-up) to achieve a clear view of the QoL in patients suffering for CLI patients. RESULTS: Twenty-five articles describing HS in patients suffering from CLI were included. It was found that while most of these articles reported HS of patients, rarely did they report on QoL. As a result, it is difficult to determine the best treatment to increase HS as studies that focus on the comparison of treatment modalities are lacking. All 4 treatment modalities can raise HS in the short and the long terms; however, endovascular and surgical revascularization seem to positively effect HS the most. QoL results are lacking in both the short and long terms. CONCLUSIONS: All treatment methods included in the study resulted in an increase in patients' HS in both short and long terms. More comparative studies with inclusion of all different treatments of CLI are needed to assist in clinical decision making and perform tailored interventions for the individual patient. QoL and HS are confusingly used in current international literature with abundant HS research. To take patients individual opinions more into account, focus on QoL research is needed to designate the superior treatment in patients suffering from CLI.

Midterm follow-up of quality of life following peripheral bypass surgery.

BACKGROUND: Peripheral bypass surgery is an important treatment option for patients with peripheral arterial disease. Short-term results of quality of life (QoL) after peripheral bypass surgery showed an increase in QoL at 3 months. Little is known about QoL at more than 2 years of follow-up. This study was performed to analyze QoL at midterm follow-up, and overall survival after peripheral bypass surgery. METHODS: This study was part of a randomized control trial in which intermittent pneumatic compression was compared with compression stockings in the treatment of edema after bypass surgery. Patients completed a QoL questionnaire before surgery, 14 days and 3 months postoperatively, and at least 2 years after the original operation. A survival analysis was performed to calculate survival for patients who received both autologous and polytetrafluoroethylene (PTFE) bypass grafts. RESULTS: The original study consisted of 93 patients, and QoL midterm follow-up was achieved for 42. QoL scores at midterm follow-up were comparable to the preoperative baseline scores for both the autologous and the PTFE groups. Three-year survival rates were 75% and 54%, respectively. CONCLUSION: Although peripheral bypass surgery significantly increased QoL 3 months after surgery, midterm follow-up showed a return to baseline scores. No significant difference was found in survival between patients in the autologous and PTFE groups.

Magnetic resonance imaging reveals edema-like changes not only subcutaneously, but also in muscle tissue after femoropopliteal bypass surgery.

BACKGROUND: The pathophysiological mechanisms that induce postrevascularization edema after femoropopliteal bypass surgery are not completely understood. Reperfusion-associated injury to revascularized tissue and damage to lymphatic structures are both likely to play a role. Aim of this study was to study edema formation after peripheral bypass surgery with magnetic resonance imaging. MATERIALS AND METHODS: Nine patients suffering from severe peripheral arterial occlusive disease were subjected to magnetic resonance imaging scans before and 1 week after autologous femoropopliteal or femorocrural bypass surgery. RESULTS: A 12% increase in volume of the upper legs and an 11% increase in volume of the lower legs were measured in patients postoperatively. The increase of volume was largely due to expansion of the subcutaneous compartments: a 35% increase in the upper legs and a 41% increase in the lower legs. Edema in the upper legs was predominantly located medially at the site of the surgical wound. In contrast, edema in the lower legs was homogenously distributed around the entire leg circumference. The muscle compartment showed no significant change of volume. However, in the majority of patients, edema-like changes were seen in selected muscles as well after a peripheral bypass reconstruction. CONCLUSION: Swelling of the subcutaneous compartments is mainly responsible for the volume increases in upper and lower legs similar to lymphatic edema. In addition, in a majority of patients, edema-like changes in selected muscles were seen especially in the upper legs. Reperfusion-associated injury as a cause of these changes cannot be ruled out.

Quality of life in perspective to treatment of postoperative edema after peripheral bypass surgery.

BACKGROUND: To examine the effects of peripheral bypass surgery on patients' quality of life (QoL) as well as to compare two treatment modalities to reduce postoperative edema with regard to patients' QoL. METHODS: This was a randomized controlled trial set in the department of vascular surgery in a nonacademic teaching hospital. Ninety-three patients (mean age, 70 years; 33% Rutherford 5-6), enrolled between August 2006 and September 2009, who underwent peripheral bypass surgery (autologous 57, polytetrafluoroethylene 36). Patients were assigned to intermittent pneumatic compression (n = 46) or to compression stockings (n = 47). The main outcome measure was QoL, measured with the World Health Organization Quality of Life assessment instrument (short form: WHOQOL-BREF). RESULTS: QoL improved on the domain of Physical Health by 7.18 points (P < 0.001 [range, 0-100]) after 2 weeks and by 10.03 points (P < 0.001) after 3 months. Patients who received a polytetrafluoroethylene bypass scored 0.45 points (P = 0.0008 [range, 1-5]) lower at baseline on Global QoL than patients who received an autologous bypass. Type of bypass or edema treatment method did not affect the improvements. Edema did not correlate with QoL. CONCLUSION: Improvement in QoL on the domain Physical Health following femoropopliteal bypass surgery was found as soon as 2 weeks after surgery. Improvement in QoL domains was not influenced by the type of bypass reconstruction. No specific effects of edema on QoL were detected.

Prospective randomized controlled trial to analyze the effects of intermittent pneumatic compression on edema following autologous femoropopliteal bypass surgery.

BACKGROUND: Patients who undergo autologous femoropopliteal bypass surgery develop postoperative edema in the revascularized leg. The effects of intermittent pneumatic compression (IPC) to treat and to prevent postreconstructive edema were examined in this study. METHODS: In a prospective randomized trial, patients were assigned to one of two groups. All patients suffered from peripheral arterial disease, and all were subjected to autologous femoropopliteal bypass reconstruction. Patients in group 1 used a compression stocking (CS) above the knee exerting 18 mmHg (class I) on the leg postoperatively for 1 week (day and night). Patients in group 2 used IPC on the foot postoperatively at night for 1 week. The lower leg circumference was measured preoperatively and at five postoperative time points. A multivariate analysis was done using a mixed model analysis of variance. RESULTS: A total of 57 patients were analyzed (CS 28; IPC 29). Indications for operation were severe claudication (CS 13; IPC 13), rest pain (10/5), or tissue loss (7/11). Revascularization was performed with either a supragenicular (CS 13; IPC10) or an infragenicular (CS 15; IPC 19) autologous bypass. Leg circumference increased on day 1 (CS/IPC): 0.4%/2.7%, day 4 (2.1%/6.1%), day 7 (2.5%/7.9%), day 14 (4.7%/7.3%), and day 90 (1.0%/3.3%) from baseline (preoperative situation). On days 1, 4, and 7 there was a significant difference in leg circumference between the two treatment groups. CONCLUSIONS: Edema following femoropopliteal bypass surgery occurs in all patients. For the prevention and treatment of that edema the use of a class I CS proved superior to treatment with IPC. The use of CS remains the recommended practice following femoropopliteal bypass surgery.

Reliability of the Inverse Water Volumetry Method to Measure the Volume of the Upper Limb.

BACKGROUND: Lymphedema of the upper extremity is a common side effect of lymph node dissection or irradiation of the axilla. Several techniques are being applied in order to examine the presence and severity of lymphedema. Measurement of circumference of the upper extremity is most frequently performed. An alternative is the water-displacement method. The aim of this study was to determine the reliability and the reproducibility of the "Inverse Water Volumetry apparatus" (IWV-apparatus) for the measurement of arm volumes. PATIENTS AND METHODS: The IWV-apparatus is based on the water-displacement method. Measurements were performed by three breast cancer nurse practitioners on ten healthy volunteers in three weekly sessions. RESULTS: The intra-class correlation coefficient, defined as the ratio of the subject component to the total variance, equaled 0.99. The reliability index is calculated as 0.14 kg. This indicates that only changes in a patient's arm volume measurement of more than 0.14 kg would represent a true change in arm volume, which is about 6% of the mean arm volume of 2.3 kg. CONCLUSION: The IWV-apparatus proved to be a reliable and reproducible method to measure arm volume.

Treatment strategies and clinical aspects of lower limb edema following peripheral bypass surgery.

In selected patients who suffer from severe peripheral artery disease (PAD) a revascularization with a peripheral bypass might be considered. Postoperative edema is a well-known phenomenon following peripheral bypass surgery and is probably caused by multiple factors. Although postoperative edema causes discomfort to patients, the effects on the quality of life are unknown. Treatment and preventive strategies should nonetheless aim at achieving a net absorption of fluid from the interstitial space into the vascular or lymphatic compartment. A brief summarization of treatment strategies of lower limb edema will be presented that include the use of compression stocking and intermittent pneumatic compression. So far, the postoperative application of compression stockings seem to prevent and reduce edema as much as possible. Quality of life improves slightly following peripheral bypass surgery. However, a contribution of edema on the quality of life could not be detected.

[Time lost between stroke and carotid endarterectomy]. / Tijdverlies van beroerte tot carotisendarteriëctomie.

OBJECTIVE: To establish whether measures taken to shorten the interval of time between a stroke and carotid endarterectomy (CEA) procedure at two Dutch hospitals had any effect. DESIGN: Retrospective and descriptive. METHOD: Data were gathered on all patients with symptomatic narrowing of the carotid artery from a non-academic teaching hospital (Amphia Ziekenhuis in Breda) as well as from a university clinic dedicated to carotid abnormalities (University Medical Center Utrecht, UMCU). 'Pass-through' intervals were analysed from 2006 and 2007 and compared with those from 2010 when the sequence of hospital care had been improved in terms of time interval from stroke up to and including CEA. The time interval between the first symptoms of stroke and the first visit to the outpatient clinic specialist was determined, as well as the time interval between the stroke and CEA procedure. RESULTS: After the hospitals had taken measures to shorten the time interval between a stroke and an operation, the percentage of patients who had undergone surgery within 2 weeks in 2010 was 34% at Amphia Ziekenhuis and 21% at the UMCU, as opposed to 5.5% (2006) and 10.5% (2007), respectively. The median time between first symptoms and surgery had decreased from 40 to 19 days at Amphia Ziekenhuis and from 57 to 36 days at the UMCU. CONCLUSION: At both the non-academic clinic and the university centre dedicated to carotid abnormalities, the majority of symptomatic patients had not undergone surgery within 2 weeks of a stroke in 2010. A CEA must therefore become a semi-acute operation instead of a semi-elective one in order to meet its associated performance criteria in the near future.

Endovascular Treatment of an Axillary Pseudoaneurysm Following a Traumatic Shoulder Dislocation.

A pseudoaneurysm following a shoulder dislocation is considered rare. We report here a case of an 82-yearold man who suffered from vascular and neurological injury due to an axillary pseudoaneurysm following anterior dislocation of the left shoulder. An emerging swelling in the shoulder region was caused by a hematoma and a slowly bleeding pseudoaneurysm in combination with reactive swelling of the soft tissues. Neurological damage occurred due to local compression. A minimally invasive technique was used to treat the pseudoaneurysm. Embolization was initially attempted, but this treatment failed. A stent was subsequently inserted to eliminate the axillary pseudoaneurysm from the circulation. Early imaging and an aggressive endovascular treatment should be considered in all patients suffering from an axillary artery (pseudo)aneurysm.
