Reports of strategies of thrombus removal for acute deep venous thrombosis (DVT), especially in patients with iliofemoral DVT, consistently demonstrate improved outcomes relative to postthrombotic morbidity. Randomized trials support the observation that a strategy of thrombus removal reduces postthrombotic syndrome in patients with extensive proximal DVT. Unfortunately, there have been few randomized trials to date and they do not stand up to rigorous methodological review. This results in relatively weak recommendations by national and international guidelines for treatment strategies designed to eliminate thrombus. This report reviews the outcomes of randomized studies of treatments designed to remove thrombus from the venous system, including operative venous thrombectomy, systemic thrombolysis, and catheter-directed thrombolysis. Hopefully, the reader can put these results into perspective versus those anticipated with anticoagulation alone.

Intraoperative vascular anastomosis occlusion due to cold agglutinin disease during brain surgery: a case report.
JA Clin Rep
January 2025
Department of Anesthesiology and Pain Medicine, Gifu University Hospital, 1-1 Yanagido, Gifu, 501-1194, Japan.
Background: Cold agglutinin disease (CAD) is an autoimmune hemolytic anemia that induces blood coagulation and hemolysis upon exposure to cold temperatures. Strict temperature control is essential to mitigate these effects, especially during surgical procedures where hypothermia is possible.
Case Presentation: A 57-year-old male, 165 cm and 72 kg, diagnosed with CAD, underwent cerebral vascular anastomosis.
Hindfoot Nailing for Surgical Management of Open Ankle Fractures in the Elderly: A Systematic Review.

Open ankle fractures in the elderly are increasingly common, with significant morbidity and mortality. Management is challenging due to poor soft tissue conditions, comorbidities, and limited functional independence. While traditional surgical options include external fixation or open reduction and internal fixation (ORIF), hindfoot nail (HFN) fixation may offer advantages, including immediate weight-bearing and reduced immobilisation complications.

We present a case of a 60-year-old man with claudication in his right foot; the patient had received stent-graft implantation for the right superficial femoral artery (SFA) 1 year ago. Computed tomography angiography suggested stent occlusion of the right SFA, and a thrombus was considered to cause occlusion. To avoid distal embolization, we performed lesion recanalization via a trans-ankle intervention.

Heart Center, Women and Children's Hospital, Qingdao University, 6 Tongfu Road, Qingdao, 266034, Shandong, China.
Objectives: To evaluate the efficacy and safety of purse-string sutures (PSS) compared with manual compression for access hemostasis in children with atrial septal defects (ASDs) after large-caliber venous delivery sheaths removal.
Methods: We conducted a retrospective clinical data review of 271 children with ASDs who underwent transcatheter device closure through large-caliber venous delivery sheaths (≥ 8 Fr) at our institution from January 2018 to January 2023. The PSS group (n = 144) was compared to the control group (n = 127), which underwent manual compression for femoral venous hemostasis after sheath removal, focusing on hemostatic time, limb braking time, bed rest time, hospital stay, and vascular access complications.
A case of surgical treatment combined with interventional therapy for refractory hemodialysis access with catheter-related right atrial thrombosis.

Division of Nephrology, West China Hospital of Medicine, Chengdu, Sichuan, China.
This case report describes a surgical treatment combined with interventional therapy for a patient with refractory hemodialysis access combined with catheter-related right atrial thrombosis (CRAT). During surgery, an artificial graft was established from the left brachiocephalic vein to the right atrium and the right atrial thrombus was removed. After the operation, the tunneled cuffed catheter (TCC) was replaced with digital subtraction angiography (DSA).
