Slope failure is very common phenomenon in hilly regions, especially in young techno active mountainous like Himalayas. It is hazardous because of the accompanying progressive movement of the slope-forming material. In order to minimize the landslide effects, slope failure analysis and stabilization requires in depth understanding of the process that governs the behavior of the slope. The present article mainly deals with the analysis of the stability of road cut slopes of Rudraprayag Area, Uttarakhand, India. The area experiences local as well as regional slides every year. Extensive field study was carried out along the road cut slopes. Laboratory experiments were conducted to determine the various Physio-mechanical properties of rock mass. These properties have been used as input parameters for the numerical simulation of slope using FLAC3D (Fast Lagrangian Analysis of Continua) including geological discontinuities. The computed deformations and the stress distribution along the failure surface are compared with the field observations. The study indicates that the overall slope is unstable except at the location E where slope is critically stable. The effects of instability have been thoroughly considered and remedial measures have been recommended.

We describe a rare complication of percutaneous transhepatic biliary drainage in a 51-year-old female with recurrent hilar cholangiocarcinoma. The patient presented with blood-mixed pericatheter leak of bile, 1 month after placement of a 10F ring biliary internal-external drainage catheter through the left-sided biliary radical. Color Doppler and triphasic computed tomography angiography revealed a pseudoaneurysm arising from segment 3 branch of the left hepatic artery and an arterioportal fistula immediately distal to the pseudoaneurysm. Endovascular coil embolization of the hepatic artery proximal to the pseudoaneurysm was done which resulted in occlusion of the pseudoaneurysm and fistula as well as clinical improvement in the symptoms.
