Endovascular Thrombus Removal for Acute Iliofemoral Deep Vein Thrombosis.

BACKGROUND: The ATTRACT trial (Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis) previously reported that pharmacomechanical catheter-directed thrombolysis (PCDT) did not prevent postthrombotic syndrome (PTS) in patients with acute proximal deep vein thrombosis. In the current analysis, we examine the effect of PCDT in ATTRACT patients with iliofemoral deep vein thrombosis. METHODS: Within a large multicenter randomized trial, 391 patients with acute deep vein thrombosis involving the iliac or common femoral veins were randomized to PCDT with anticoagulation versus anticoagulation alone (No-PCDT) and were followed for 24 months to compare short-term and long-term outcomes. RESULTS: Between 6 and 24 months, there was no difference in the occurrence of PTS (Villalta scale ≥5 or ulcer: 49% PCDT versus 51% No-PCDT; risk ratio, 0.95; 95% CI, 0.78-1.15; P=0.59). PCDT led to reduced PTS severity as shown by lower mean Villalta and Venous Clinical Severity Scores ( P<0.01 for comparisons at 6, 12, 18, and 24 months), and fewer patients with moderate-or-severe PTS (Villalta scale ≥10 or ulcer: 18% versus 28%; risk ratio, 0.65; 95% CI, 0.45-0.94; P=0.021) or severe PTS (Villalta scale ≥15 or ulcer: 8.7% versus 15%; risk ratio, 0.57; 95% CI, 0.32-1.01; P=0.048; and Venous Clinical Severity Score ≥8: 6.6% versus 14%; risk ratio, 0.46; 95% CI, 0.24-0.87; P=0.013). From baseline, PCDT led to greater reduction in leg pain and swelling ( P<0.01 for comparisons at 10 and 30 days) and greater improvement in venous disease-specific quality of life (Venous Insufficiency Epidemiological and Economic Study Quality of Life unit difference 5.6 through 24 months, P=0.029), but no difference in generic quality of life ( P>0.2 for comparisons of SF-36 mental and physical component summary scores through 24 months). In patients having PCDT versus No-PCDT, major bleeding within 10 days occurred in 1.5% versus 0.5% ( P=0.32), and recurrent venous thromboembolism over 24 months was observed in 13% versus 9.2% ( P=0.21). CONCLUSIONS: In patients with acute iliofemoral deep vein thrombosis, PCDT did not influence the occurrence of PTS or recurrent venous thromboembolism. However, PCDT significantly reduced early leg symptoms and, over 24 months, reduced PTS severity scores, reduced the proportion of patients who developed moderate-or-severe PTS, and resulted in greater improvement in venous disease-specific quality of life.

Quality of Life after Radioembolization for Hepatocellular Carcinoma Using a Digital Patient-Reported Outcome Tool.

Health-related quality of life (HRQoL) measurements are important for patient care, and emerging bundles in value-based care are placing an increasing emphasis on tying reimbursement to patient surveys. A multicenter pilot study was carried out to assess the efficacy of an automated digital patient engagement (DPE) platform for collecting HRQoL measurements at baseline and at 2- to 4-week intervals through 90 days after transarterial radioembolization (TARE) with yttrium-90 (90Y) treatments for hepatocellular carcinoma (HCC). The results revealed a survey completion of 78.4% and demonstrated only 4 of 35 individual symptom instances across all time points of transient worsening relative to baseline. Most importantly, the DPE platform provided an effective means for deploying and collecting patient-reported outcome measures.

Vacuum-assisted thrombectomy device (AngioVac) in the management of symptomatic iliocaval thrombosis.

Three patients with complete iliocaval thrombosis causing symptomatic leg swelling failed initial treatment with standard pharmacomechanical techniques. The occluded segments of the inferior vena cava and iliac veins were subsequently treated with the AngioVac Cannula (AngioDynamics, Latham, New York) and extracorporeal venous bypass circuit. In each patient, symptoms improved after treatment. This report discusses potential benefits and ancillary techniques of using the AngioVac device for iliocaval venous thrombosis.

Improvement in chronic pelvic pain, orthostatic intolerance and interstitial cystitis symptoms after treatment of pelvic vein insufficiency.

OBJECTIVES: Comorbidities associated with venous origin chronic pelvic pain (VO-CPP) were evaluated pre and post venous treatment to assess change. MATERIALS AND METHODS: 45 women with VO-CPP were treated with venous stenting and/or embolization. Four surveys assessed symptoms pre- and post-treatment: IPPS (chronic pelvic pain), PUF (interstitial cystitis), OHQ (dysautonomia), and modified ROME III (IBS). Prevalence of joint hypermobility was investigated. RESULTS: Ages were 18-65. Pretreatment, 64% and 49% of women were in the severe range for PUF and OHQ, respectively. 40% and 56% met criteria for IBS and Ehlers-Danlos syndrome/Hypermobility Spectrum Disorder (EDS/HSD), respectively. 17eceived an iliac stent, 5 pelvic embolization, and 23 both. Post-treatment, average scores improved: IPPS (by 55%), PUF (34%), and OHQ (49%). Rome III improved only slightly. CONCLUSION: Pelvic pain, interstitial cystitis, and dysautonomia were frequently found with VO-CPP and improved after venous treatment. EDS/HSD and IBS were common in these women.

Pancreatic arteriovenous malformation: a case report and literature review.

Most pancreatic arteriovenous malformations (PAVM) present due to gastrointestinal bleeding or abdominal pain, but these patients may be asymptomatic. Increased portal vein flow from these malformations can lead to portal hypertension and gastrointestinal bleeding. Diagnosis is often made by imaging, and early diagnosis has led to successful surgical resection or percutaneous embolization. We report a patient with PAVM, diagnosed by CT and angiography, who has remained asymptomatic for 2 years without treatment.

Cutaneous thermal injury after endovenous laser ablation of the great saphenous vein.

Herein a case of cutaneous thermal injury in the leg of a patient who underwent endovenous laser (EVL) ablation of an incompetent great saphenous vein (GSV) is reported. Follow-up ultrasonography (US) of the site of skin burn showed that the burn was directly over thrombosed superficial tributaries originating from the GSV, but medial to the treated GSV. At the level of skin burn, the thrombosed GSV was 22 mm deep, but the tributaries were 1 mm deep. In addition, US showed echogenic fat surrounding and conforming to the superficial thrombosed tributaries. Based on the clinical scenario and follow-up US findings, it was concluded that the cutaneous thermal injury resulted from heated blood traveling from the 22-mm-deep GSV to the superficial tributaries directly beneath the site of skin burn.

Sonography of delayed effects of uterine artery embolization on ovarian arterial perfusion and function.

OBJECTIVE: We aimed to assess the delayed effects of uterine artery embolization on ovarian arterial perfusion and function by performing ovarian sonography immediately before and after uterine artery embolization, as well as several months later. CONCLUSION: Although persistent loss of detectable arterial perfusion after uterine artery embolization occurs in some women, most patients reestablish arterial perfusion and do not develop symptoms of ovarian failure.

Comparison of pain after uterine artery embolization using tris-acryl gelatin microspheres versus polyvinyl alcohol particles.

When compared in a uterine artery embolization (UAE) animal model, Embospheres (ES) (Biosphere Medical, Rockland, MA) were found to induce less uterine ischemia than polyvinyl alcohol (PVA) particles. Given this finding, we aimed to test the hypothesis that ES is associated with less pain after UAE than PVA in human patients. We performed retrospective analysis on data from 72 consecutive UAE patients, collected from a prospectively acquired database. Patient-controlled analgesia (PCA) pump-delivered morphine sulfate (MS) dosages were compared between patients who received ES versus PVA. Subjective pain scores (SPS) were also compared between the two groups. Secondary outcome measures, including embolic volume and clinical outcome data, were also collected. Linear regression and t-test statistical analyses were performed. Null hypotheses were rejected at the p < 0.05 level. Mean follow-up period in the PVA population was 178 days (range 28-426), versus 96 days (range 24-197) in the ES population. The mean MS doses used by ES and PVA patients were 37.2 (s.d. 23.5) versus 47.1 (s.d. 26.8), respectively. This difference was not significant (p > 0.15). Utilizing a standard 0-10 pain scale, the mean peak SPS for the ES and PVA groups were 5.58 (s.d. 2.77) and 5.07 (s.d. 2.99), respectively. The difference was not significant. The mean amount of embolic material used in each ES and PVA patient was 4.86 cc (s.d. 3.01) and 3.52 cc (s.d. 1.63), respectively. The difference revealed a strong trend toward statistical significance (p = 0.05). There was one treatment failure in each group of patients. Within both patient samples, no significant correlation was found when comparing the volume of embolic used and subsequent MS dose. Despite a strong trend toward a significantly higher volume of ES used per patient, there is no subjective or objective difference in pain after UAE with ES when compared to PVA.
