Kay AB, Morris DS, Woller SC, Collingridge DS, Majercik S. Below the knee, let it be: Management of calf DVT in hospitalized trauma patients. Am J Surg 2023; 226:891-895. [PMID: 37574336 DOI: 10.1016/j.amjsurg.2023.07.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 07/28/2023] [Accepted: 07/31/2023] [Indexed: 08/15/2023]
Abstract
INTRODUCTION Management of below-knee DVT (BKDVT) in trauma patients is uncertain. We hypothesized that BKDVT can be managed with observation only. METHODS Secondary analysis on trauma inpatients March 2017-September 2019 with risk assessment profile ≥5. Management of BKDVT included observation with ultrasound. BKDVT was compared to above-knee DVT (AKDVT), and BKDVT with progression to AKDVT/PE compared to no progression. RESULTS Of 1988 patients, 136 (6.8%) BKDVT and 23 (1.2%) AKDVT. 7 (6.9%) BKDVT progressed to AKDVT/PE. 6.9% had BKDVT progression, associated with higher ISS (36.7 vs 21.6, p = 0.005), longer prophylaxis delay (121 vs 45 h, p = 0.02) and longer hospital LOS (25.6 vs 7.8, p = 0.01). None experienced post-thrombotic syndrome. CONCLUSION Majority of BKDVT in hospitalized trauma patients did not progress to AKDVT. Observation for progression, rather than treatment, was not associated with increased PE risk or thrombotic sequelae. Observation with serial ultrasound may serve as a practical alternative to anticoagulation in trauma patients with BKDVT.

Suboptimal Use of DOACs Post-Discharge for Geriatric Hip Fractures with Isolated Calf Deep Vein Thrombosis: Do Clinician Prescribing Preferences and Patient Compliance Alters Clinical Outcomes? Clin Interv Aging 2023; 18:1423-1436. [PMID: 37663122 PMCID: PMC10473050 DOI: 10.2147/cia.s421422] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Accepted: 08/06/2023] [Indexed: 09/05/2023] Open
Abstract
Introduction This study aimed to examine the impacts of DOACs compliance and prescribing preferences on clinical outcomes in elderly hip fracture patients with isolated calf deep vein thrombosis (ICDVT). Methods We conducted a retrospective cohort study that evaluated 702 patients who underwent surgical treatment combined with ICDVT in an academic university hospital between January 2016 and October 2021. DOACs compliance was investigated through telephone and outpatient follow-up, and ICDVT clinical outcomes were collected 30 and 90 days post-discharge, respectively. Variables of interest were collected through the electronic medical record system, and data were analyzed after adjusting for predictors of non-completely dissolved (CD) of ICDVT. Results The DOACs compliance survey revealed that 375 (53.42%) patients were fully adherent, 270 (38.46%) were fairly adherent, and 57 (8.12%) were poorly adherent. Approximately 62% of patients had ICDVT dissipation within 30 days after discharge, reaching 94% within 90 days. DOACs QD/BID regimen is often based on economic status, activity capacity, discharge destination and post-operative weight-bearing activities (p<0.05).The mechanism of injury, ASA classification, surgical technique and timing of ICDVT formation were significantly correlated with DOACs 14/28 days regimen (p<0.05).Multivariate analysis revealed that rural patients [OR 1.518 (95% CI, 1.117-2.236)], pre-operative ICDVT[OR 2.816 (95% CI, 1.862-4.259)] and thrombus length [OR 1.157 (95% CI, 1.263-1.821)] were ICDVT risk factors for non-CD. Furthermore, DOACs fair compliance [OR 0.087 (95% CI, 0.042-0.178)], DOACs full compliance [OR 0.283 (95% CI, 0.139-0.579)], and hospitalization duration [OR 0.793 (95% CI, 0.694-0.907)] were ICDVT protective factors for CD. Conclusion Better compliance with DOACs benefits early ICDVT dissipation, but final clinical outcomes have to be validated with longer follow-up periods. When managing elderly patients with hip fractures, indications for anticoagulation should be considered and individualized protocols should be used.

Abstract
BACKGROUND An established treatment strategy for asymptomatic pulmonary embolism (PE) or deep vein thrombosis (DVT) remains uncertain in Japan; therefore, in this study, we clarify the characteristics and outcomes of symptomatic compared to asymptomatic patients with PE or DVT. METHODS This prospective, multicenter sub-analysis of the J'xactly study in Japan included 1,016 patients (mean age, 68; 41% male) with venous thromboembolism (VTE) treated with rivaroxaban. RESULTS Asymptomatic PE patients (47% of PE patients) were more likely to have active cancer and asymptomatic proximal DVT at lower severity than symptomatic PE patients, despite no differences in age, sex, or the proportion receiving intensive 30 mg/day-rivaroxaban. Patients with asymptomatic DVT (34% of DVT patients) were older, had higher rates of female sex, active cancer, and distal DVT, and received shorter, less intense rivaroxaban treatment. Incidences did not differ between asymptomatic and symptomatic PE patients for recurrent symptomatic VTE (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.22-1.62; P = 0.31) or major bleeding (HR, 0.68; 95% CI, 0.20-2.33; P = 0.58), nor between asymptomatic and symptomatic DVT patients for recurrent symptomatic VTE (HR, 0.56; 95% CI, 0.23-1.40; P = 0.21) and major bleeding (HR, 1.47; 95% CI, 0.54-3.97; P = 0.45). CONCLUSIONS The real-world composite adverse event rate for treatment with rivaroxaban, as physician-adjusted for dose and duration, was similar for asymptomatic and symptomatic patients regardless of the presence of PE or DVT, suggesting a favorable safety profile for potential rivaroxaban treatment for asymptomatic VTE.

Ann Med Surg (Lond) 2022; 77:103627. [PMID: 35638069 PMCID: PMC9142657 DOI: 10.1016/j.amsu.2022.103627] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2022] [Revised: 04/11/2022] [Accepted: 04/11/2022] [Indexed: 11/25/2022] Open
Abstract
Background Pulmonary embolism (PE) from deep venous thrombosis (DVT) can be a fatal postoperative complication. Preventive measures for venous thromboembolism (VTE) was evaluated in this hospital. Materials and methods Preoperative DVT screening following surgery under general anesthesia in 2009–2016 was examined, and then, 217 patients diagnosed with DVT by preoperative leg-ultrasound (US) between 2014 and 2016 were retrospectively analyzed. Results There were 24,826 operations under general anesthesia in the study period. Preoperative leg-US was performed in 5345 (21.5%) patients, and 648 (12.1% of patients, 2.6% of total operations) were diagnosed with DVT. In 2014–2016, 217 patients, which is 11.7% of patients undergoing leg-US, were diagnosed with DVT. DVT was found in the proximal veins (upper popliteal vein) in 86 (39.6%) patients. A total of 143 (62%) patients were considered to have organized thrombi, no patient developed pulmonary embolism, and 133 (58%) patients were discharged without follow-up examination for DVT. Ninety-six patients were evaluated for changes on leg-US, with no difference in the results with and without anticoagulant use. On multivariate logistic regression analysis, anticoagulants appeared effective for non-organized thrombi, higher D-dimer levels (≥10 μg/mL), or orthopedic surgery. Conclusion Preoperative screening for DVT did not appear useful, and treatment of asymptomatic DVT was not always necessary. Preoperative screening of leg-ultrasound diagnosed 12% of patients with DVT. Developing symptomatic embolism was not associated with anticoagulant use. Anticoagulants were effective for non-organized thrombi, higher D-dimer levels, or orthopedic surgery. Preoperative screening for DVT did not appear useful.

Abstract
Isolated calf deep venous thrombosis (ICDVT) includes thrombosis located at the far end of the popliteal vein, such as the anterior tibial vein, posterior tibial vein, fibular vein, and intramuscular vein of the soleus and gastrocnemius. This type of thrombosis has the highest incidence, accounting for approximately half of all deep vein thrombosis (DVT) cases; however, there is no consistent recommendation for ICDVT treatment across countries, and there is also no optimal management strategy. In recent years, increasing evidence has shown that ICDVT can develop into proximal DVT, even causing pulmonary embolism (PE). Therefore, some experts suggest anticoagulant therapy for this type of DVT, while others hold an opposing attitude. Therefore, the treatment strategy for this type of DVT has become a hot and difficult research topic. The purpose of this review is to summarize the characteristics of ICDVT and the effects of different treatment strategies by analyzing recent and important classical works in the literature in an attempt to provide recommendations for the treatment of this most common type of DVT in orthopaedic clinics.

Direct Oral Anticoagulant Therapy for Isolated Distal Deep Vein Thrombosis Associated with Cancer in Routine Clinical Practice. J Clin Med 2021; 10:jcm10204648. [PMID: 34682770 PMCID: PMC8539627 DOI: 10.3390/jcm10204648] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 09/30/2021] [Accepted: 10/08/2021] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND The efficacy and bleeding complications of direct oral anticoagulant (DOAC) therapy for isolated distal deep vein thrombosis (IDDVT) associated with cancer in routine clinical practice remain unclear. Moreover, prior studies on prolonged therapy for IDDVT are limited. METHODS This retrospective study enrolled 1641 consecutive patients with acute venous thromboembolism (VTE) who had received oral anticoagulant therapy, including warfarin or DOAC, between April 2014 and September 2018 in our institutions. In these patients, 200 patients with cancer-associated IDDVT were evaluated. RESULTS Mean follow-up period was 780 ± 593 days. Major bleeding and VTE recurrence were observed in 22 (11.0%) and 11 (5.5%) patients, respectively. In multivariate analysis, statistically significant factors correlated with major bleeding were advanced cancer stage, high performance status, stomach cancer, and gallbladder cancer; those correlated with all-cause death were advanced cancer stage, high performance status, liver dysfunction, pancreatic cancer, and major bleeding. Cumulative events of major bleeding and recurrence between patients with prolonged DOAC therapy (≥90 days) and those with nonprolonged therapy were not significantly different. CONCLUSIONS Preventing major bleeding is important because it is a significant risk factor for all-cause death. Major bleeding and recurrent events were comparable between prolonged and nonprolonged therapy.

Abstract
Purpose An antegrade approach is frequently used in catheter-directed thrombolysis to remove deep-vein thrombosis. However, the antegrade approach is difficult when accessing veins with small diameters; therefore, understanding the variation of deep calf vein is important. Methods This study measured the diameters and surface areas of the proximal and distal posterior tibial vein, peroneal vein, and anterior tibial vein to determine which are preferable for venous access. This study dissected 132 legs from Korean and Thai cadavers. The proximal and distal posterior tibial vein, peroneal vein, and anterior tibial vein were scanned and measured. Results The mean diameter and surface area were largest for the proximal tibial vein, at 6.34 mm and 0.312 cm2, respectively, followed by the anterior tibial vein (5.22 mm and 0.213 cm2), distal posterior tibial vein (3.29 mm and 0.091 cm2), and peroneal vein (3.43 mm and 0.081 cm2). The proximal posterior tibial vein and anterior tibial vein have large diameters and surface areas, which make them ideal for applying an antegrade approach in catheter-directed thrombolysis. Conclusions The distal posterior tibial vein and peroneal vein are not recommended due to their smaller surface areas and also the anatomical variations therein.

Abstract
OBJECTIVE We aimed to evaluate the prevalence of pulmonary embolism (PE) before cancer therapies in patients with ovarian and endometrial cancers with enhanced computed tomography (CT) using D-dimer (DD), and determine the optimal cut-off level of DD. METHODS Since 2009, we have performed preoperative venous thromboembolism (VTE) screening of patients with ovarian and endometrial cancer. For patients with DD levels of more than 1.0 μg/ml, enhanced CT images were obtained from the pulmonary apex to the foot to detect PE and deep venous thrombosis (DVT) simultaneously. RESULTS Among patients with ovarian cancer, 84 of 413 (20.3%) had VTEs (DVT alone, n = 31 [7.5%]; PE with or without DVT, n = 53 [12.8%]; PE alone, n = 12 [2.9%]). Among patients with endometrial cancer, 50 of 455 (11.0%) had VTEs (DVT alone, n = 19 [4.2%]; PE with or without DVT, n = 31 [6.8%], PE alone, n = 14 [3.1%]). The optimal cut-off level of DD was estimated to be ≥1.5 and ≥1.2 μg/ml in ovarian and endometrial cancers, respectively. CONCLUSION Our study revealed a high prevalence of PE before cancer therapies in patients with ovarian and endometrial cancers by enhanced CT using DD.

Abstract
OBJECTIVE Although distal deep vein thrombosis (DDVT) has been more frequently diagnosed with the availability of better ultrasound imaging quality, the data on the best method to manage DDVT have been conflicting. The aim of the present review was to summarize the current and evidence-based recommendations for the diagnosis and management of DDVT and to provide a summary of the most recent societal guideline recommendations. METHODS A literature review of DDVT was performed. The PubMed databases were queried for articles on the epidemiology, risk factors, diagnosis, and management of DDVT. RESULTS The prevalence of isolated DDVT has been reported in a broad range. The reported risk factors include older age, active malignancy, a low degree of mobility, acute infection, and atrial fibrillation. With more evidence, anticoagulation therapy was found to be associated with a reduced risk of recurrent venous thromboembolism (VTE) and/or thrombus propagation compared with conservative management. However, anticoagulation was associated with an increased risk of bleeding in a number of studies. The rate of VTE recurrence ranged from 7% to 23% during a follow-up period ranging from 3 months to 8 years. The significant risk factors for VTE recurrence included cancer, older age, an unprovoked event, and inpatient status. CONCLUSIONS Few studies have addressed the diagnosis and management of DDVT. Further research is needed to standardize the best approach to diagnose and treat DDVT.

Abstract
INTRODUCTION This study proposes variations in the posterior tibial vein as one of the risk factors for deep-vein thrombosis. Understanding the anatomical classification of the posterior tibial vein would guide the antegrade approach of catheter-directed thrombolysis. MATERIALS AND METHODS One hundred thirty-four legs from Korean and Thai cadavers were dissected. The posterior tibial veins were classified into four types according to the number of proximal and distal veins. RESULTS The most common type was type Ia (64/134), followed by type IIa (28/134), type Ib (24/134), and type IIb (16/134). CONCLUSIONS The anterior tibial and fibular veins had exactly two paired veins; however, the posterior tibial vein had many variations. We assume that patients with type IIb and IIa have a higher risk of thrombosis and hidden symptoms due to collateral formation. Additionally, the classification of the posterior tibial vein and dividing into proximal and distal posterior tibial vein would help practitioners predict the course and guide the application of catheter-directed thrombolysis.

Abstract
Background: The natural history of asymptomatic isolated distal deep vein thrombosis (DVT) of the leg is unclear. This study aimed to describe a 3-month and 1-year clinical course after diagnosis of asymptomatic isolated distal DVT of the leg. Methods: This study included 127 patients with asymptomatic, sonographically proven isolated distal DVT who did not receive anticoagulant therapy and were retrospectively evaluated at our hospital between May 2014 and September 2016. After 3 months and 1 year, the presence or absence of venous thromboembolism recurrence and extension of DVT toward proximal veins was sonographically confirmed. Results: At 3-month and 1-year follow-ups, 125 and 109 patients were observed, respectively. All patients showed no symptoms or findings suspecting venous thromboembolism recurrence during the observation period. However, 43 patients underwent repeat ultrasonic examination, and thrombus extension was confirmed in 2 patients. Conclusions: Asymptomatic isolated distal DVT of the leg showed good prognosis, and thus uniform anticoagulation therapy was considered unnecessary.

Application of the Caprini Risk Assessment Model for Evaluating Postoperative Deep Vein Thrombosis in Patients Undergoing Plastic and Reconstructive Surgery. Ann Vasc Surg 2019; 65:82-89. [PMID: 31678541 DOI: 10.1016/j.avsg.2019.10.082] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 09/02/2019] [Accepted: 10/22/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND The optimal approach for assessing the risk of venous thromboembolism (VTE) in patients undergoing plastic surgery is yet to be established. This study aimed to determine the validity of the Caprini Risk Assessment Scale in identifying patients undergoing plastic surgery who are at a high risk of developing VTE. METHODS Between December 2014 and November 2015, we enrolled 90 patients. Risk factors for VTE were assessed at baseline. The Caprini Risk Assessment Model was used to stratify patients into Caprini <4, Caprini 5-6, Caprini 7-8, and Caprini >8 groups before examination. We preoperatively screened for deep vein thrombosis (DVT) using duplex ultrasound. During operation, surgical duration and blood loss were recorded. Duplex ultrasound was repeated 2 and 7 days postoperatively to evaluate for DVT. We used a univariate analysis to determine risk factors for postoperative VTE. Confounding predictors were finally tested using a multivariate logistic regression analysis. RESULTS One patient had preoperative DVT and was excluded from the study. Eighty-nine patients were included in the final analyses. Of the 89 patients, 7 (8%) developed postoperative DVT. Mean age, body mass index, Caprini score, and surgical duration were significantly higher in patients who developed postoperative DVT. Variables associated with increased risk of postoperative DVT using univariate analysis were Caprini scores of 7-8 and >8. Multivariate logistic regression analysis finally identified Caprini scores 7-8 [odds ratio (OR) 13, 95% confidence interval (CI) 1.67-101.98, P = 0.014] and >8 (OR 19.5, 95% CI 1.02-371.96, P = 0.048) to be independently associated with postoperative DVT. CONCLUSIONS Although the incidence of postoperative DVT is relatively low among patients undergoing plastic surgery, Caprini scores can be used to predict postoperative VTE complications.

Abstract
目前,肺癌的发病率和死亡率在全世界范围内居首位。静脉血栓栓塞症(venous thromboembolism, VTE)是一种公认的肺癌并发症,也是肺癌患者的主要死因之一。癌症自身因素、患者自身因素以及治疗相关因素都是导致肺癌患者发生VTE的主要原因。肿瘤细胞可产生组织因子(tissue factor, TF)、癌性促凝物质(cancer procoagulant, CP)、炎症因子和细胞因子,从而直接激活凝血;其中TF过度表达是肿瘤患者血栓形成的主要机制之一。2016年美国胸外科医师协会(American College of Chest Physicians, ACCP)发布的第10版肿瘤患者VTE防治指南(AT-10)指出,抗凝治疗是肺癌患者合并VTE的基本治疗措施;其中低分子肝素(low molecular-weight-heparin, LWMH)被认为是首选的抗凝药物,但要注意出血风险。

Abstract
In our varicose vein center, on a trial basis, among the patients with asymptomatic calf deep vein thrombosis (CDVT) we carefully selected the patients for varicose vein surgery using the requirements as follows; 1) the patients had varicose veins with incompetent saphenous veins, 2) sequential examination including DUS confirmed stability and clinical insignificance of asymptomatic CDVT, 3) the patients do not have any risk factors for DVT such as a coagulation profile disorder (antithrombin deficiency, protein C deficiency, protein S deficiency, or antiphospholipid syndrome) or malignancies, 4) surgery is possible under local anesthesia alone, and 5) the patients can understand the concept of asymptomatic CDVT and undergo the surgery on their own will and informed consent. The patients who fulfilled these conditions underwent the varicose vein surgery. Twenty-eight patients with 30 limbs with varicose veins had asymptomatic CDVT, found by preoperative duplex ultrasonography (DUS). Among CDVT, 91% of CDVT existed in the soleal veins. After the diagnosis of the asymptomatic CDVT, serial DUS was performed and showed no changes in the status of the thrombus. Then varicose vein surgery (high ligation of the saphenous junctions either with or without stripping of the saphenous veins) was performed. After the surgery, the CDVT was re-evaluated by DUS. In 27 limbs, CDVT did not show any changes in the status of the thrombus, and in 3 limbs the CDVT was partially resolved. These data suggest that, at least, as far as the patients fulfilled these conditions, varicose vein surgery did not worsen the asymptomatic CDVT.

Abstract
OBJECTIVE Provoked deep venous thrombosis (DVT) is precipitated by a specific event. This paper compares the characteristics of provoked DVT in patients with transient risk (TR) factors and patients with continuous risk (CR) factors. METHODS A retrospective review of records of all consecutive patients diagnosed with DVT between January 2013 and August 2014 was performed. Patients with provoked DVT were included in the TR group if the provoking event resolved in 2 weeks and they did not have ongoing risk of thrombosis. Patients in the CR group had a provoked DVT with ongoing risk of thrombosis due to individual factors deemed to be ongoing risks of thrombosis, such as cancer, hypercoagulable disorder, and prolonged immobilization. Demographics, risk factors, association with pulmonary embolism (PE) and its severity, risk of recurrent venous thromboembolism (VTE), and mortality were compared between the two groups. RESULTS A total of 838 patients were diagnosed with DVT, and 50.7% (425) were provoked. There were 127 (29.9%) patients with TR and 298 (70.1%) with CR. TR patients were younger (60.4 ± 16.3 vs 65.9 ± 16.0; P = .001). TR was more likely to be provoked by surgery (70.9% vs 55.4%; P = .003), whereas CR was more likely to be provoked by immobilization (21.5% vs 12.6%; P = .032). CR patients were affected by cancer (48.7%) and hypercoagulable disorders (4.4%). TR patients were more likely to have calf DVTs (36.2% vs 26.2%; P = .047). There was a trend toward lower association with PE on presentation in TR (17.3% vs 21.1%; P = .072), but that did not reach statistical significance. However, TR factors were more likely to be associated with low-risk PE compared with CR factors (30.2% vs 54.6%; P = .040). After mean follow-up of 7.2 months, CR had higher risk of recurrent VTE (14.0% vs 6.8%; P = .045) and mortality (23.5% vs 7.1%; P < .0001). CONCLUSIONS Provoked DVT with CR factors affects older patients and is associated with high recurrence of VTE and mortality compared with provoked DVT with TR factors.

Abstract
Essentials Clinical significance of cancer-related isolated distal deep vein thrombosis (iDDVT) is unknown. We studied patients with iDDVT, with and without cancer, and proximal DVT with cancer. Cancer-related iDDVT patients have a much poorer prognosis than iDDVT patients without cancer. Cancer-related iDDVT patients have a similar prognosis to cancer-related proximal DVT patients. SUMMARY Background Isolated distal deep vein thrombosis (iDDVT) (infra-popliteal DVT without pulmonary embolism [PE]) is a frequent event and, in the absence of cancer, is usually considered to be a minor form of venous thromboembolism (VTE). However, the clinical significance of cancer-related iDDVT is unknown. Methods Using data from the observational, prospective multicenter OPTIMEV cohort, we compared, at 3 years, the incidences of death, VTE recurrence and major bleeding in patients with cancer-related iDDVT with those in cancer patients with isolated proximal DVT (matched 1:1 on age and sex) and patients with iDDVT without cancer (matched 1:2 on age and sex). Results As compared with patients with cancer-related isolated proximal DVT (n = 92), those with cancer-related iDDVT (n = 92) had a similar risk of death (40.8% per patient-year (PY) vs. 38.3% per PY; aHR = 1.0, 95% CI[0.7-1.4]) and of major bleeding (3.8% per PY vs. 3.6% per PY, aCHR = 0.9 [0.3-3.2]) and a higher risk of VTE recurrence (5.4% per PY vs. 11.5% per PY; aCHR = 1.8 [0.7-4.5]). As compared with patients with iDDVT without cancer (n = 184), those with cancer-related iDDVT had a nine times higher risk of death (3.5% per PY vs. 38.3% per PY; aHR = 9.3 [5.5-15.9]), a higher risk of major bleeding (1.8% per PY vs. 3.6% per PY; aCHR = 2.0 [0.6-6.1]) and a higher risk of VTE recurrence (5.0% per PY vs. 11.5% per PY; aCHR = 2.0 [1.0-3.7]). The results remained similar in the subgroup of patients without history of VTE. Conclusion Patients with cancer-related iDDVT seem to have a prognosis that is similar to that of patients with cancer-related isolated proximal DVT and a dramatically poorer prognosis than patients with iDDVT without cancer. This underlines the high clinical significance of cancer-related iDDVT and the need for additional studies.

Abstract
BACKGROUND To investigate the usefulness of popliteal artery spectral doppler findings as a complimentary approach to isolated calf vein thrombosis (DVT). MATERIAL/METHODS We included consecutive patients presenting with symptomatic and sonographically proven acute isolated calf DVT. Patients with thrombosis of any other vein were excluded. We classified calf vein into into four main types. We investigated how many of these four vessels had DVT and compared them with respect to the pulsatility index (PI) value of the popliteal artery. RESULTS We evaluated spectral doppler characteristics of the popliteal artery on the same side as the isolated calf vein thrombosis as well as on the opposite side. The relationship between PI values of the popliteal artery and the number of thrombosed calf veins was investigated. In patients with 1 and/or 2 thrombosed veins, the mean PI was 6.03±0.54 on the side of cDVT and 5.68±0.39 on the opposite side (p=0.008), respectively. Inpatients with 3 and/or 4 thrombosed veins, the mean PI was 8.05±0.61 on the side of cDVT and 6.34±0.47 on the opposite side (p=0.001), respectively. CONCLUSIONS Venous doppler sonography for the evaluation of calf DVT may be limited by patient characteristics such as obesity, edema, and tenderness., Arterial PI can be used as a complimentary technique for the detection of venous thrombosis in such of cases.

Abstract
BACKGROUND The severity of pulmonary embolism (PE) after isolated calf deep vein thrombosis (C-DVT) is controversial, which leads to inconsistent clinical decision making when treating C-DVT. This systematic review assessed PE frequency and severity in patients with C-DVT. METHODS Database searches were completed using MEDLINE and Scopus along with cross-referencing. Two independent reviewers used using rigorous inclusion and exclusion criteria to screen the papers. Data concerning PE and C-DVT characteristics as well as methods of detection were abstracted. Studies reporting combined outcomes for patients with proximal and C-DVT, those with concurrent PE at diagnosis, and retrospective studies not allowing the determination of C-DVT and PE as separate events were excluded. RESULTS Of 586 papers that were screened, 21 met inclusion criteria, which included eight randomized clinical trials and 13 prospective cohort studies. There was data heterogeneity among patients, methods of diagnosis, and follow-up. PE diagnosis was often based on ventilation/perfusion scanning, where more recent studies used computed tomography angiography. The PE is usually overestimated because it includes concurrent events. The incidence of PE from isolated C-DVT in our review was 0% to 6.2%. No fatal PEs were reported. No data were found on PE severity and patient outcomes regarding this complication. CONCLUSIONS Reported adverse outcomes of PE from C-DVT are infrequent, and clinical severity is unclear. Further studies are necessary to determine the actual risk associated with PE after C-DVT to establish proper treatment.

Abstract
Abstract
Background
A large number of studies have examined the potential complications of calf deep vein thrombosis (DVT). There is no consensus on when or how to treat patients to prevent these complications. This systematic review assessed the rate of proximal propagation, pulmonary embolism, major bleeding and recurrence in patients with isolated calf DVT.
Methods
Database searches of MEDLINE, the Cochrane Library, Scopus, CINAHL and Web of Science were undertaken along with extensive cross-referencing. Two independent reviewers screened the papers using stringent inclusion and exclusion criteria. Included studies were graded on six methodological standards. Data on propagation, pulmonary embolism, recurrence and major bleeding were abstracted.
Results
A total of 4261 papers were found; 15 met the inclusion criteria, including five randomized clinical trials and ten prospective cohort studies. The propagation rate to the popliteal vein or above was around 9 per cent and the rate of pulmonary embolism was close to 1·5 per cent. No studies found anticoagulant therapy to reduce the rate of adverse outcomes.
Conclusion
The literature on calf DVT is heterogeneous, limiting conclusions from data analysis. Adverse outcomes are infrequent and studies do not suggest that they are reduced by anticoagulation.

Abstract
BACKGROUND Distal deep venous thrombosis (DVT) accounts for approximately half of all the cases of lower limb thrombosis. The impact and management of this condition is still controversial. This study aims to evaluate the incidence of pulmonary embolism (PE) in patients with distal DVT in comparison to proximal DVT and evaluate the correlation between DVT and PE extension. METHODS 100 patients with acute lower limb DVT diagnosed with whole leg Doppler ultrasound from January 2006 to December 2014 were retrospectively analyzed. Active investigation for PE was carried out in all patients using multislice computed tomography angiography. Classification of DVT and PE was based on the proximal extension of the thrombus. RESULTS The overall incidence of PE in our sample patients was 72%. In the subgroup analysis, incidence of PE was equal in both the proximal and distal DVT groups (77%, p > 0.99). PE was detected in 43% of the patients with isolated calf vein thrombosis (ICVT). No statistical difference was observed between the distribution of lobar, segmental and subsegmental PE in the 3 DVT subgroups (p = 0.665); however, truncular PE was only observed in the proximal DVT group. CONCLUSION Distal DVT is associated with a high incidence of PE compared to proximal DVT. Distal DVT and ICVT can provoke PE with involvement of proximal vessels in the pulmonary arterial tree, even in asymptomatic patients. Our study arises discussion in the controversial debate regarding the need for routine anticoagulation in distal DVT.

Abstract
Thrombi of the soleal and gastrocnemius veins of the leg remain incompletely characterized in terms of the appropriate treatment algorithm to follow. Although they are anatomically located below the level of the fascia, making them "deep" vein thrombi, their natural history is unclear with respect to propagation and embolization. Varying treatment suggestions have been proposed, from full-dose anticoagulation to "watchful waiting" with repeated duplex examination, with none rising to the level of accepted scientific evidence. Herein, we present the current literature citing the differing opinions and data that have confused the subject.

Abstract
The treatment of isolated calf vein thrombosis remains widely debated. This study highlights the characteristics of isolated calf vein thrombosis in cancer patients and compares to isolated calf vein thrombosis in patients without history of cancer. Between July 2013 and April 2014, a retrospective chart review of consecutive patients with isolated calf vein thrombosis was performed recording patient risk factors, ultrasound characteristics of the thrombus, treatment modalities, long-term recurrence of venous-thromboembolism, incidence of bleeding, and mortality. Of 131 patients with isolated calf vein thrombosis, 53 (40.1%) had history of cancer. Isolated calf vein thrombosis occurred at an older age in cancer patients (66.7 vs 58.5 years, p = 0.004). The anatomical characteristics of isolated calf vein thrombosis on ultrasound were comparable in both groups. Isolated calf vein thrombosis in cancer patients was less likely to be treated with anticoagulation (60.4% vs 80.8%, p = 0.018). However, a trend towards higher incidence of bleeding after initiation of anticoagulation for isolated calf vein thrombosis in cancer patients (11.3% vs 6.4%, p = 0.351) was noted. Mortality in cancer patients was higher (37.7% vs 9.00%, p < 0.001) but was unrelated to isolated calf vein thrombosis or its treatment. In conclusion, the risks of bleeding seem to exceed the benefits of anticoagulation in approximately 50% of cancer patients with isolated calf vein thrombosis. The management of isolated calf vein thrombosis does not seem to impact the survival of cancer patients.

Abstract
BACKGROUND Isolated distal deep vein thrombosis (IDDVT) is frequently found in symptomatic outpatients, but its long term outcome is still uncertain. AIMS To assess IDDVT long term outcome and the impact of IDDVT characteristics on outcome. METHODS In a prospective, single center study we enrolled symptomatic outpatients in whom IDDVT was detected by whole-leg compression ultrasonography. Patients with provoked IDDVT were treated with low molecular weight heparins (LMWH) for 30 days while those with unprovoked IDDVT received with vitamin K antagonists (VKA) for three months. The primary end-point was the rate of the composite of pulmonary embolism (PE), proximal deep vein thrombosis (DVT), and IDDVT recurrence/extension during 24 month follow-up. RESULTS 90 patients (age 61 ± 18, male 48.9%) were enrolled. Risk factors for thrombosis were reduced mobility (34.4%), obesity (25.3%), surgery (15.6%), and previous DVT (15.6%) and cancer in 8 patients (8.9%). Eighty-eight patients were treated (56 with LMWH and 32 with VKA). During follow-up (median 24 ± 2 months), 17 events were recorded, which included 3 PE (two in cancer patients), 4 proximal DVTs (one in cancer patient) and 10 IDDVT. Male sex (HR 4.73 CI95%: 1.55-14.5; p=0.006) and cancer (HR 5.47 CI95%: 1.76-17.6; p=0.003) were associated with a higher risk of complications, whereas IDDVT anatomical characteristics, anticoagulant therapy type, and provoked IDDVT were not. CONCLUSIONS The risk of recurrent venous thromboembolism after IDDVT may be relevant in male patients or in patients with active cancer. Larger studies are needed to address this issue.

Abstract
BACKGROUND Australia has two published national guidelines for general medical thromboprophylaxis (MT), but the two differ in detail and the basis for patient selection remains uncertain. Several aspects of current guidelines are controversial, as is the proposed design of a dedicated prescribing box in the National Inpatient Medication Chart. AIM To discuss and comment on the current standing of medical thromboprophylaxis in Australia. METHOD We have marshalled literature known to us from our previous published research, and have applied this knowledge to discuss shortcomings, which, in our opinion, exist in current medical thromboprophylaxis practice, and to suggest solutions. CONCLUSION Australian guidelines are flawed because they are based on unsuitable evidence (incidence of subclinical thrombotic disease) and define eligibility broadly, such that about 80 per cent of patients are considered eligible. They urge that prescribers should "consider" prophylaxis without supplying an adequate basis for doing so. They do not provide grounds for assessing the balance between hazard (in the form of major bleeds) and benefit (thrombotic events avoided). Other clinical factors promoting unnecessary use of medical thromboprophylaxis include the use of age as a risk factor and proposed inclusion of a new DVT prophylaxis section in the National Inpatient Medication Chart (NIMC), which implicitly discourages non-prescription of prophylaxis.

Abstract
Isolated distal deep-vein thromboses (DVT) are infra-popliteal DVT without involvement of proximal veins or pulmonary embolism (PE). They can affect deep calf (tibial anterior, tibial posterior, or peroneal) or muscular (gastrocnemius or soleal) veins. They represent half of all lower limbs DVT. Proximal and distal DVTs differ in terms of risk factor profile, proximal DVT being more frequently associated with chronic risk factors and distal DVT with transient ones. Their natural history (rate of spontaneous proximal extension) is debated leading to uncertainties on the need to diagnose and treat them with anticoagulant drugs. In the long term, the risk of venous thromboembolic recurrence is lower than that of proximal DVT and their absolute risk of post-thrombotic syndrome is unknown. French national guidelines suggest treating with anticoagulants for 6 weeks a first episode of isolated distal DVT provoked by a transient risk factor and treating for at least 3 months unprovoked or recurrent or active cancer-related distal DVT. The use of compression stockings use is suggested in case of deep calf vein thrombosis. Ongoing therapeutic trials should provide important data necessary to establish an evidence-based mode of care, especially about the need to treat distal DVT at low risk of extension with anticoagulants.
