Isolated spontaneous dissection of the superior mesenteric artery (SMA) is a rare cause of acute mesenteric ischemia. Two patients were successfully treated by percutaneous stent placement within the main trunk of the SMA. Emphasis is placed on the feasibility of nonsurgical management with percutaneous stent placement of isolated spontaneous dissection of the SMA.
Inferior vena cava (IVC) thrombosis after traumatic liver injury is an extremely rare condition, and only 12 cases have been reported in the English literature since 1911. We report a case of a 26-year-old man who presented with IVC thrombosis after blunt liver injury. IVC thrombosis was incidentally detected by computed tomography 15 days after conservative management of blunt liver injury. The patient denied any symptoms of thrombophlebitis and did not have any evidence of hypercoagulable state. We placed an IVC filter via the right jugular vein and started the anticoagulation treatment. The patient recovered successfully without operative treatment and IVC thrombosis disappeared completely two months later. We suggest that that the possibility of IVC thrombosis should be considered in patients with a large hematoma of the liver, which may cause compression of the IVC.
We report a case of 53-year-old woman with an injured popliteal artery due to excessive drilling with a drill bit during medial opening wedge high tibial osteotomy (MOWHTO). Pseudoaneurysm was diagnosed three days after surgery and confirmed by urgent computed tomography (CT) angiography. Open vascular surgery with resection of the perivascular hematoma and end-to-end anastomosis using ipsilateral saphenous vein interposition graft was performed. CT angiography at 8 months postoperatively showed that blood flow was maintained without obstruction of the graft site and active dorsiflexion of the foot was possible. To reduce neurovascular injury during MOWHTO, it is important not to drill the far cortex at the proximal part of the osteotomy site when using a drill bit, and the metal should be positioned posteromedially as much as possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
