Objectives Multiple organ failure is a rare manifestation of ilio-iliac arteriovenous fistula which can lead to a high rate of misdiagnosis and death. Methods We reported a 61-year-old man presenting with multiple organ failure rapidly after right lower limb swelling. Computed tomography angiography showed an ilio-iliac arteriovenous fistula caused by right common iliac artery aneurysm, and venous thrombosis of bilateral common iliac veins. A bifurcated stent-graft with coil embolization of right internal iliac artery was used for repair. Results The patient recovered rapidly and was discharged without complications. Although arteriovenous fistula persisted due to type II endoleak, aneurysm sac and inferior vena cava significantly shrunk at six months follow-up. Conclusions This report demonstrated that multiple organ failure may appear when the distal outflow tracts of arteriovenous fistula are obstructed. Moreover, endovascular repair is effective for reversal of multiple organ failure caused by arteriovenous fistula, even if arteriovenous fistula persists due to type II endoleak.

Abstract Background and aims This experimental study assesses the influence of different gases and insufflation pressures on the portal, central-venous and peripheral-arterial pH during experimental laparoscopy. Methods Firstly, 36 male WAG/Rij rats were randomized into six groups (n = 6) spontaneously breathing during anaesthesia: laparoscopy using carbon dioxide or helium at 6 and 12 mmHg, gasless laparoscopy and laparotomy. 45 and 90 min after setup, blood was sampled from the portal vein, vena cava and the common femoral artery with immediate blood gas analysis. Secondly, 12 animals were mechanically ventilated at physiological arterial pH during 90 min of laparotomy (n = 6) or carbon dioxide laparoscopy at 12 mmHg (n = 6) with respective blood gas analyses. Results Over time, in spontaneously breathing rats, carbon dioxide laparoscopy caused significant insufflation pressure-dependent portal acidosis (pH at 6 mmHg, 6.99 [6.95–7.04] at 45 min and 6.95 [6.94–6.96] at 90 min, pH at 12 mmHg, 6.89 [6.82–6.90] at 45 min and 6.84 [6.81–6.87] at 90 min; p < 0.05) compared to laparotomy (portal pH 7.29 [7.23–7.30] at 45 min and 7.29 [7.20–7.30] at 90 min; p > 0.05). Central-venous and peripheral-arterial acidosis was significant but less severely reduced during carbon dioxide laparoscopy. Laparotomy, helium laparoscopy and gasless laparoscopy showed no comparable acidosis in all vessels. Portal and central-venous acidosis during carbon dioxide laparoscopy at 12 mmHg was not reversible by mechanical hyperventilation maintaining a physiological arterial pH (pH portal 6.85 [6.84–6.90] (p = 0.004), central-venous 6.93 [6.90–6.99] (p = 0.004), peripheral-arterial 7.29 [7.29–7.31] (p = 0.220) at 90 min; Wilcoxon–Mann–Whitney test). Conclusion Carbon dioxide laparoscopy led to insufflation pressure-dependent severe portal and less severe central-venous acidosis not reversible by mechanical hyperventilation.

Ivc Filters

Inferior vena cava (IVC) filters are recommended for patients with proximal deep vein thrombosis (DVT) who are not eligible for anticoagulation. Long-dwelling filters are well-known to be associated with the development of IVC thrombosis. Chronic caval occlusion can lead to a severe post-thrombotic syndrome (PTS), with manifestations of chronic venous insufficiency in the lower extremities. Animal studies have shown that post-thrombotic inflammation can trigger the development of an arteriovenous fistula (AVF), however, there is limited evidence for this phenomenon in patients with PTS. We describe the case of a spontaneous AVF in a patient with long-standing IVC thrombosis. It was postulated that the AVF could be compounding the venous hypertension and severe swelling of his lower extremities. The case additionally demonstrates the successful results of endovascular recanalisation for an occluded filter in the presence of an AVF.

We present a case of a high cardiac output (CO) arteriovenous fistula (AVF) with pulmonary hypertension (PH) post-double lung transplant presenting for AVF occlusion. The patient presented with a CO of 9.83 L/min, pulmonary artery pressures of 64/16, inferior vena cava dilatation and an AVF between the left common iliac artery and vein. Given her anaesthetic considerations, we elected to proceed with local anaesthesia and sedation. Trial balloon occlusion resulted in an increase in blood pressure and a headache that resolved with balloon deflation. Successful final occlusion with an endovascular stent was completed without adverse events. PH is a complex pathophysiology with the potential for catastrophic decompensation. Anaesthesiologists must consider a patient’s comorbidities and the procedure to safely administer anaesthesia without complications.
