ABSTRACT
Objective:To evaluate multi-channel transcatheter embolotherapy for type Ⅱ endoleak originating from lumbar arteries after endovascular abdominal aortic aneurysm repair (EVAR).Methods:Data of 8 cases of type Ⅱ endoleak after EVAR from Oct 2017 to Nov 2020 at the Department of Vascular and Endovascular Surgery, Henan Provincial People's Hospital were retrospectively analyzed.Results:All patients who suffered from type Ⅱ endoleak that originated from lumbar arteries after EVAR were successfully treated with coils and mixture of Compant medical glue and iodipin through multi-channel. The technical success rate was 100%, the operative time was 80-150 min. Right lower limb dyskinesia occurred in 1 patient after operation, the symptom disappeared by anticoagulation and trophic neurotherapy for 2 months. Type Ⅱ endoleak didn't recur in all patients, and no mortality during the 4-38(14.1) months follow-up period.Conclusion:Multi-channel transcatheter embolotherapy has definite effects for the treatment of type Ⅱ endoleak from lumbar arteries after EVAR, with high technical feasibility, few perioperative complications, low mortality among other advantages. The results of short and medium term are satisfactory.
ABSTRACT
Objective:To summarize the clinical experience and effect of applying 3D printing assisted with the technology of extracorporeal pre-fenestration in the treatment of thoracic/abdominal aortic aneurysm.Methods:From August 2019 to November 2020, 15 patients with thoracic/abdominal aneurysm involving visceral arteries were admitted to our center, including 11 males and 4 females, with mean age of 57-82(68.26 ±4.73) years old. According to diameters of visceral artery, thoracic aorta, abdominal aorta, and bilateral iliac arteries measured by CTA, we selected suitable stents and made a 3D printing model by professional software to guide the position of intraoperative external fenestration and the fenestration diameter to implement full cavity repair.Results:All operations were completed and one case was converted to laparotomy. The average time of operations was(200.67±41.00)min and hospital stay was(13.47±4.16)days without any death, organ failure, endoleak, paraplegia, graft infection and other complications.Conclusion:The application of 3D printing assisted with the technology of extracorporeal pre-fenestration in the treatment of thoracic/abdominal aortic aneurysm is feasible and effective, and the short-term results are satisfactory.
ABSTRACT
Objective:To study the treatment outcomes of transjugular intrahepatic portal shunt (TIPS) on refractory hepatic sinus obstruction syndrome (HSOS) caused by Gynura segetum.Methods:The clinical data of 15 patients with refractory HSOS caused by Gynura segetum treated at the Department of Vascular Surgery, Henan Provincial People's Hospital from January 2017 to April 2021 were retrospectively analyzed. There were 7 males and 8 females, with ages ranging from 30 to 85 years, mean ± s. d. (61.2±14.1) years. Albumin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, glutamyl transferase, and portal vein pressure were compared before and after TIPS. The liver function and renal function of these patients were followed up.Results:When compared with pre-operation, the albumin, alanine aminotransferase, aspartate aminotransferase and other indexes were significantly improved after TIPS (all P<0.05). The portal vein pressure of 15 patients significantly decreased from the preoperative volume of (41.7±3.5) cmH 2O (1 cmH 2O=0.098 kPa) to (28.3±4.4) cmH 2O ( t=10.41, P<0.001). The preoperative liver function was Child-Pugh grade A in 1 patient, grade B in 8 patients, grade C in 6 patients. The postoperative Child-Pugh grading was grade A in 14 patients and grade B in 1 patient. Ascites, gastrointestinal bleeding, abdominal pain, abdominal distention and spontaneous peritonitis all disappeared in these 15 patients. Postoperative hepatic encephalopathy developed in 2 patients and hepatic myelopathy in 1 patient. Conclusion:TIPS for treatment of HSOS caused by Gynura segetum resulted in a rapid recovery of liver function, rapid symptomatic relief, with a low incidence of hepatic encephalopathy/hepatic myelopathy.
ABSTRACT
Objective:To investigate the effect of free anterolateral thigh perforator flap on repair of bone exposure of diabetic foot ulcer.Methods:From Sep. 2016 to Dec. 2019, free anterolateral thigh perforator flap was used to repair 19 cases of diabetic foot ulcer with bone exposure. The area of the flap ranged from 5.0 cm×7.0 cm to 10.0 cm×16.0 cm. The donor site of the flap was sutured directly. The patients were followed up regularly by outpatient and telephone.Results:18 of the 19 cases survived completely, in one case, most of the flap were necrotic, healed after second stage skin grafting; 5 flaps developed edema due to low albumin, and healed after stitches removal, dehydration, albumin supplement and secondary suture and antibiotic replacement. Through 6 to 24 months of follow-up study we concluded that flap transfer could functionally and morphologically repair wounds with soft tissue defect and infection.Conclusion:Free anterolateral thigh perforator flap is effective in repairing diabetic foot ulcer and can effectively reduce disability rate.
