Bronchobiliary fistula is a rare and is an uncommon but severe complication of hydatid disease of the liver. Treatment has traditionally been surgical resection, but embolization and stent placement have been described. The invasive method seems to be a key component of patient treatment. We describe a case of a 58-year-old woman who, 25 years before, had undergone surgery for a hydatid cyst. A total cystectomy without previous puncture or parasite extraction was carried out. The lower aspect of the cyst was found to be completely perforated over the biliary duct. During the postoperative course, the patient had subphrenic right-sided pleural effusion and biliary fistula that subsided with medical treatment. Afterward, the patient came to the outpatient area of our hospital complaining of leakage of purulent exudate through the cutaneous opening, pain located on the right hypochondrium radiating to the right hemithorax, malaise, fever, chronic cough, and occasional vomiting of bile. Fistulography revealed an anfractuous cavity communicating with a residual cystic cavity on the right hepatic lobe. We observed communication with the intrahepatic canaliculi. Computed tomographic scan revealed a fistulous tract on the anterior liver border through the abdominal wall. There were no posttreatment complications. The patient is asymptomatic.

Objective: Superior venous system stenosis (superior vena cava (SVC) -right subclavian vein -innominate vein -left subclavian vein) is a clinical situation that frequently appears in patients with long-term implanted cardiac stimulation devices, due to venous system thrombosis and in those with congenital heart disease who need corrective surgery, due to chronic complications inherent to surgical techniques. In clinical practice, venous system stenosis may manifest as a SVC syndrome. In many cases, we are not able to correct stenosis or obstructions, since it is impossible to cross them. In this article, we describe the surgical technique that we have implemented in our hospital to solve this challenge, especially in those patients with pacing/defibrillation devices who present with this pathology. Our objective was to perform an extraction of the pacemaker and defibrillation electrodes, to allow the passage of a support wire to achieve the implantation of the endovascular stent(s) to correct the SVC syndrome. Methods: We present a retrospective series of six consecutive patients with SVC syndrome studied in a single center from 2012 to 2021.Three of them presented with thrombosis related to pacing or defibrillation electrodes and the other three presented with complications derived from Mustard or Senning techniques in patients with pacemakers and D-transposition of the great arteries. Results: In all cases, a complete re-vascularization of the SVC system was achieved using a stent, and new leads could have been implanted through it. Combined treatment of lead extraction and endovascular stent implantation corrected the syndrome in all cases. Conclusions: Angioplasty and stenting of the central venous system is a standardized technique with validated results, in acute, for the recanalization of chronic occlusions secondary to transvenous devices.
