Objectives: Pregnancy represents a special situation where both the mechanical and hormonal instigating factors of varicose veins are reversible with the venous valve cusps preserved. Exostent venous valve repairs are a physiological alternative which minimises stimulus to collateral growth (recurrence). The study purpose was to assess the effect of pregnancy on the durability of valve repairs.
Methods: In a prospective study of 36 limbs, 20 young females (30 ± 4.7 years) had an exostent implanted to the terminal valve of the saphenofemoral junction for varicose veins. At routine long-term follow up (9.7 ± 3.8 years), 38 pregnancies were completed (mean: 1.8, range: 1-4). The controls were a non-pregnant group of limbs (n = 386).
Results: At 9.7 years, the internal diameter of the greater saphenous vein (GSV) changed from 7.8 ± 2.8 mm preoperatively to 4.5 ± 1.4 mm post-operatively. Recurrence was associated with reflux, preoperative deep system and ovarian vein involvement. Pregnancy induced 33.3% recurrences compared with non-pregnant controls (4.7%) similarly treated or 22.8% compared with non-pregnant ablative controls. At 9.7 years, symptomatic improvement continued with significantly better CEAP status (described later) (31CSEAP preoperative to 6CSEAP) with no further truncal ablation (strip, laser) required.
Conclusions: Venous valve repairs can withstand the special stresses of pregnancy. There is no need to ablate the GSV. This approach is contrary to the traditional dictum; the treatment of varicose veins should be delayed until the family is completed.

Infective Endocarditis With Origin in Orbital Vascular Malformation and Maxillary Sinusitis: A Case Report and Review of Four Patients in the Literature.

Infective endocarditis is a life-threatening disease and the early diagnosis is crucial for a better outcome. We report an old adult who developed infective endocarditis in association with new-onset maxillary sinusitis as well as proptosis, which was caused by an orbital mass lesion in the background of pre-existing orbital vascular malformation. A 74-year-old woman was found incidentally to have right orbital vascular (venous) malformation by head magnetic resonance imaging when she was hospitalized for left dorsal pontine infarction.

Transvenous extraction of the leads in children is associated with a higher risk of serious complications, that is why it is reluctantly performed. Unfortunately, this conservative approach has been associated with secondary complications (tricuspid valve dysfunction and bilateral venous obstruction), adverse events during lead removal procedure and recanalization and stenting of chest veins. We present a case of a 27-year-old female with a pacemaker and insertion of two new leads on the opposite side of the chest leaving the old ones in place.

Noncardiogenic pulmonary edema after cardiac surgery is a rare but severe complication. The etiology remains poorly understood; however, the issue may arise from multiple sources. Possible causes include a significant inflammatory response or an autoimmune process.

The fibroblastic sleeve is a structure potentially enveloping any intravascular device. At ultrasound scan, it typically presents as a thin layer of variably echogenic material covering the catheter surface, which usually tends to remain into the vessel after the catheter removal. However, several case reports have documented its migration toward the heart or pulmonary artery after a central venous catheter removal.

Background And Objective: Deep vein thrombosis (DVT) of the lower limbs is a critical global vascular disease. Accurately assessing and predicting the efficacy of DVT treatment remains a significant challenge due to a lack of understanding of the mechanisms by which the level of patient-specific embolization and the rate of drug injection affect thrombolytic therapy.
Methods: In this study, we used the computed tomographic venography (CTV) clinical method to obtain patient-specific parameters, and the flow-solid interaction (FSI) method combined with biochemical response modeling of thrombolysis to analyze patient-specific hemodynamic and biomechanical characteristics and to quantitatively assess the effects of three vessel embolism levels (VEL) versus two drug injection rates (DIR) on bifurcated femoral venous thrombolytic therapy.
