Surgical Management of Acute Mesenteric Ischemia; Review Article

Mesenteric ischemia is a condition in which the amount of oxygen available is insufficient to meet the needs of the intestines. The small intestine, colon, or both can be affected by ischemia. The most common cause of occlusive ischemia is an abrupt obstruction of a major artery, which causes a considerable drop in intestinal blood flow. Early diagnosis is one of the most essential components in achieving a favorable outcome. The most prevalent treatment is surgical management. However, there are minimally invasive therapy alternatives that have been shown in observational studies. For arterial thrombosis, endovascular stenting is an option, and anticoagulation is an option for venous thrombosis. Endovascular aspiration, mechanical embolectomy, and local thrombolysis are all possibilities for patients with arterial embolism.

Mapping Technologies for Catheter Ablation of Atrial Fibrillation Beyond Pulmonary Vein Isolation

Catheter ablation remains the most effective and relatively minimally invasive therapy for rhythm control in patients with AF. Ablation has consistently shown a reduction of arrhythmia-related symptoms and significant improvement in patients’ quality of life compared with medical treatment. The ablation strategy relies on a well-established anatomical approach of effective pulmonary vein isolation. Additional anatomical targets have been reported with the aim of increasing procedure success in complex substrates. However, larger ablated areas with uncertainty of targeting relevant regions for AF initiation or maintenance are not exempt from the potential risk of complications and pro-arrhythmia. Recent developments in mapping tools and computational methods for advanced signal processing during AF have reported novel strategies to identify atrial regions associated with AF maintenance. These novel tools – although mainly limited to research series – represent a significant step forward towards the understanding of complex patterns of propagation during AF and the potential achievement of patient-tailored AF ablation strategies for the near future.

Aorto Femoral Bypass Graft in Chronic Limb Ischemia Patient

A 44-year-old man was admitted to hospital to be performed re-thrombectomy after previously performed thrombectomy at the referring hospital but did not show clinical improvement. CT angiography results before re-thrombectomy showed a central thrombus measuring 1.1 cm in diameter, and an impression of 2.6 cm long at the branching of the right external Iliaca artery which caused total obstruction of the right illiaca external artery to the distal. Aortofemoral bypass graft surgery is a procedure utilized commonly for the treatment of aortoiliac occlusive disease. The treatment given to manage symptoms if medical management or minimally invasive therapy, such as balloon angioplasty and stenting, was unsuccessful or unsuitable for the patient. Aortofemoral bypass graft surgical procedure was performed on the patient. However, post procedure angiography showed no visible flow through the newly placed graft. A repair graft procedure was planned for the patient, but the patient refused to undergo further surgical procedures.
